This suggests that siglec-E up-regulation on macrophages represents a negative feedback pathway that

limits the inflammatory response to LPS signalling. A potential limitation of receptor over-expression and the use of antibodies to cross-link siglecs is that they may trigger non-physiological signalling pathways. Siglecs are normally masked on the cell surface via cis interactions with cell-expressed sialic acids, which limits the ability of exogenous trans ligands to induce clustering at 3MA the cell surface. Furthermore, the natural siglec–sialic acid interactions are much weaker than the siglec–antibody interactions and typically in the affinity range of 100–1000 μm. Alternative in vitro approaches include the use of synthetic sialylated carbohydrates to cross-link siglecs, which might better approximate the natural interactions between siglecs and their ligands on other cells in terms of both affinity and avidity. Siglec-deficient mice are proving useful in determining the precise regulatory role of siglecs as discussed further

below. Siglec-G is predominantly expressed on B cells, including the B1a RG7204 supplier cell population that is important for making rapid T-independent IgM responses to bacterial carbohydrate antigens as well as natural antibodies.41 Hoffmann et al.41 showed that siglec-G-deficient mice had a large expansion of the B1a population which began early in development and this was independently confirmed by Ding et al.42 The expansion was specific to B1a B cells and not follicular B2 B cells, which also express siglec-G.41,42 Mixed radiation chimeras prepared with 1 : 1 ratios of wild-type and siglec-G-deficient bone marrow cells, demonstrated that

the effect of siglec-G in controlling cellular expansion is B-cell intrinsic.41 The B1a-cell expansion in siglec-G-deficient mice was not the result of increased cell cycling but rather reduced turnover rate as shown by lower bromodeoxyuridine incorporation.41 These data are suggestive of increased survival Histone demethylase of B1a cells in siglec-G−/− mice, possibly through increased B-cell receptor signalling. Over-expression of siglec-G inhibited B-cell-receptor-mediated Ca2+ signalling and the siglec-G-deficient B1a cells exhibited exaggerated calcium signalling and increased IgM production.41 A similar phenotype has been observed in SHP-1-deficient mice, which exhibit expansion of the B1-cell population and higher B-cell receptor-induced calcium signalling in B cells. This suggests that SHP-1 plays a role downstream of siglec-G to give rise to its inhibitory function.43 This newly defined role of siglec-G may explain the naturally muted signalling response of B1a cells when compared with the B2 population in which siglec-G does not seem to play a functional role despite relatively high levels of expression.

Baboons (Papio anubis, from the CNRS Primatology Center, Rousset, France) were negative for all quarantine tests, including a tuberculin skin test. Animals were housed at the large animal facility of our laboratory following the recommendations of the Institutional Ethical Guidelines of the Institut National de la Santé Et de la Recherche Médicale, France. All experiments were performed under general anaesthesia with Zoletil (Virbac, Carron, France). Pharmacokinetic and pharmacodynamic

studies were performed during DTH experiments on five baboons receiving an i.v. bolus of either 1 mg/kg or 0·1 mg/kg of chimeric A9H12. Chimeric A9H12 was quantified in baboon sera using a specific sandwich ELISA. LAG-3-Ig (Immutep, Orsay, France) was immobilized on plastic at pH 9·5 overnight at a concentration of 5 µg/ml. After saturation with

5% gelatin at 37°C for 2 h, serum diluted AG-014699 order in PBS-0·05% Tween 20 were incubated for 4 h at room temperature, washed and revealed with a mouse anti-human IgG kappa chain BTK activity antibody (EFS, Nantes, France) at a 1:2000 dilution, followed by peroxidase-labelled goat anti-mouse antibody (Jackson Immunoresearch, Westgrove, PA, USA) at a 1:5000 dilution. Optical density was recorded at 450 nm after a tetramethylbenzidine (TMB) revelation period of 10 min at room temperature in the dark and addition of 25 µl 1 N sulphuric acid/well. Baboons were immunized intradermally (i.d.) twice with a bacillus Calmette–Guérin (BCG) vaccine (0·1 ml; 2–8 × 105 UFS; Sanofi Pasteur MSD, Lyon, France) in the upper region of the leg, 4 and 2 weeks before the DTH skin test. To investigate antigen-specific T cell immunity before

DTH skin testing, successful immunization was confirmed by interferon (IFN)-γ enzyme-linked immunospot (ELISPOT) assay (non-human primate IFN-γ ELISPOT kit; R&D Systems, Minneapolis, MN, USA) on freshly isolated Sitaxentan PBMC, according to the manufacturer’s instructions. Intradermal reactions (IDR) were performed with duplicate intradermal injections of two doses (2000 UI or 40 UI) of tuberculin-purified protein derivative (PPD; Symbiotics Corporation, San Diego, CA, USA) in 0·1 ml in the skin on the right back of the animals. Saline (0·1 ml) was used as a negative control. Dermal responses at the injection sites were measured using a caliper square. The diameter of each indurated erythema was measured by two observers from days 3–8, and were considered positive when > 4 mm in diameter. The mean of the reading was recorded. Skin biopsies from the DTH or control (saline) site were performed at day 4 on one duplicate and placed in Tissue Tek optimal cutting temperature (OCT) compound (Sakura Finetek, Villeneuve d’Ascq, France) for immunohistochemical analysis. A second IDR was performed after a 3-week washout period and animals received one i.v. injection of either 1 mg/kg or 0·1 mg/kg of chimeric A9H12 1 day before this second challenge with PPD.

Li and He [[10].] found PAR-4 protein expression but failed to detect the presence of PAR-4 transcripts due to technical issues. Irrespectively, also in our hands, PAR-4 expression is marginal. The presence of PAR-1, -3 and -4 at protein level in naïve monocytes suggests that cross-talking between coagulation and inflammation is possible, because PARs are sensitive to protease stimulation. Human PAR-1 can be activated by FXa and thrombin; whereas PAR-2 can be activated by FVIIa, the binary TF-FVIIa complex, FXa and the DMXAA manufacturer ternary TF-FVIIa-FXa complex; and PAR-3 and PAR-4 can be activated by thrombin [5-7, 13]. PAR activation is irreversible. Upon activation, PARs are uncoupled from signalling and then

internalized GDC-0068 molecular weight and degraded [26, 27]. Therefore, we first investigated whether stimulation of naïve monocytes with the coagulation proteases would alter PAR expression. The percentage monocytes expressing PARs and the MFI of PAR expression did not

changed upon stimulation, with the coagulation proteases suggesting that PARs were not activated and internalized [28]. We next investigated whether stimulation of naïve monocytes with coagulation proteases resulted in cytokine production. It is known that coagulating whole blood results in the production of IL-6 and IL-8 [29]. In addition, administration of FVIIa was found to elicit IL-6 and IL-8 release in healthy human subjects [30]. In our study, none of the investigated coagulation proteases induced pro-inflammatory cytokine production by naïve CD14+ monocytes. For FVIIa and the binary TF-FVIIa complex, this seems logic

regarding the absence of PAR-2 expression on naïve monocytes. For FXa and thrombin, our findings correspond to previous studies demonstrating that both FXa and thrombin did not promote monocyte IL-1β, IL-6 and TNF-α secretion [31-33]. Thus, although freshly isolated naïve monocytes express PAR-1, PAR-3 and PAR-4 at protein level, our results demonstrate that stimulation with the investigated coagulation Abiraterone solubility dmso proteases does not result in cross-talking with the inflammation cascade leading to pro-inflammatory cytokine production. To figure out which coagulation protease is responsible for the observed pro-inflammatory cytokine release in coagulating whole blood and upon FVIIa administration in vivo, we next investigated whether stimulation of PBMCs with coagulation proteases resulted in pro-inflammatory cytokine release and proliferation. From the investigated coagulation proteases, only thrombin was found to induce pro-inflammatory effects. Thrombin-induced IL-1β and IL-6 cytokine release and PBMC cell proliferation. This effect clearly appeared to be PAR-1 mediated. Because isolated CD14+ monocytes did not respond, it could be that the context of PBMC population is necessary to stimulate the monocytes. On the other hand, it is also plausible that other cells within the PBMC population were stimulated by thrombin.

We, and other groups, have recently demonstrated that B7-H1 is essentially involved in the induction and maintenance of T-cell anergy 25. There is abundant evidence that different viruses abuse B7-H1 to RG7422 turn-off effector T-cell responses 26–28. The findings of this study imply that B7-H1-mediated inhibition of T-cell responses is, at least partly, due to its capacity to contribute to the induction of IL-35 production. Yet, B7-H1 alone was not sufficient to induce IL-35, but required co-signaling via sialoadhesin. Sialoadhesin, a member of sialic acid binding lectin family of I-type lectins, preferentially

binds to sialylated carbohydrate structures (e.g. NeuAcα2,3-Gal) 29 and CD43 Small molecule library cell line has been recently described as ligand for sialoadhesin on T cells

30. Sialoadhesin is a frequently used marker for macrophages because it is typically not expressed on monocytes, lymphocytes, and DC. Yet, type-I IFN have lately been reported to up-regulate sialoadhesin on monocytes 30–33, but also on DC (our unpublished data). Thus, sensing of viral infections by DC leads to the up-regulation of the inhibitory receptor pair B7-H1 and sialoadhesin, which is critical for the induction of IL-35+ Treg. We have discovered this novel pathway of immune-regulation by analyzing the impact of HRV on DC. HRV are specialized pathogens and only infect humans with all the well-known symptoms of a cold. HRV infection is probably the most frequent human infectious disease, which indicates that the host/HRV relationship is highly evolved. HRV utilizes a variety of tricks to blunt our immune-system and induction of IL-35+ Treg may represent a further prominent immune-evasion mechanism 13. Since induction of B7-H1 and sialoadhesin expression on DC seem to be induced by many other viruses as well, it is intriguing to suggest that the induction of IL-35+ Treg is a general theme in viral infections. Cells were maintained in RPMI 1640 (Gibco, Paisley, Scotland), supplemented with 2 mM L-glutamine, 100 U/mL penicillin, 100 μg/mL streptomycin, and 10% FBS (Sigma-Aldrich, St. Louis, MO, USA). Recombinant human GM-CSF

and IL-4 were kindly provided by Novartis Research Institute (Vienna, Austria). The HRV-blocking reagent WIN 52035-2 14 was a kind gift from Arachidonate 15-lipoxygenase the Sterling-Winthrop Research Institute (Rensselaer, NY, USA) and was used at a final concentration of 5 μg/mL. IL-10,TGF-β and IL-12 were purchased from R&D Systems (Minneapolis, MN, USA). IFN-α (isoform 2c) was purchased from Boehringer Ingelheim (Vienna, Austria). Monensin, PMA, and Ionomycin were obtained from Sigma-Aldrich. Human IL35:Fc was obtained from Alexis Biochemicals (San Diego, CA, USA). The following murine mAb were generated in our laboratory: negative control Ab VIAP (against calf intestine alkaline phosphatase), 5-272 (B7-H1), 7-239 (CD169, sialoadhesin), VIT6b (CD1a).

“In this article,we revisited the anatomy of the distal perforator of the descending genicular artery (DGA) and report the clinical application of its perforator propeller flap in the reconstruction of soft tissue defects around the knee. Forty fresh human

lower limbs were dissected to redefine the anatomy of the branches of the DGA and their perforators and the anatomical landmarks for clinical applications. Five patients underwent “propeller” distal anteromedial thigh (AMT) flaps based on DGA perforators for the reconstruction of post-traumatic (n = 4) BAY 80-6946 in vivo and post-oncologic (n = 1) soft tissue defects occurring near the knee with a size ranging from 4.8 cm × 6.2 cm to 10.5 cm × 18.2 cm. A constant cutaneous perforator of the osteoarticular branch (OAB) of the click here DGA was found in the distal AMT fossa with a mean caliber of 1.2 ± 0.4 mm. It arose 9.4 ± 3.1 cm distally to the origin of the OAB and 4.0 ± 0.4 cm above the knee joint. The size of the harvested flaps ranged from 6.0 cm × 7.1 cm to 11.0 cm × 20.1 cm. All the flaps healed uneventfully at a mean period of 7.4 months. All the patients regained full range motion of the knee-joint. Our study provided evidence of the vascular supply and the clinical application of the distal AMT flap based on a constant

perforator arising from the OAB of the DGA. This flap may be a versatile alternative for the reconstruction of the defects around the knee because of its consistent vascular pedicle, pliability and thinness, adequate retrograde perfusion, and the possible direct suture of the donor site. © 2014 Wiley Periodicals, Inc.

“Background: Three-dimensional computed tomographic angiography (3D CTA) can be used preoperatively to evaluate the course and caliber of perforating blood vessels for abdominal free-flap breast reconstruction. For postmastectomy breast reconstruction, many women inquire whether the abdominal tissue volume will match that of the breast to be removed. Therefore, our

goal was to estimate preoperative volume and weight of the proposed flap and compare them with the actual volume and weight to determine if diagnostic imaging can accurately identify the amount Fluorouracil solubility dmso of tissue that could potentially to be harvested. Methods: Preoperative 3D CTA was performed in 15 patients, who underwent breast reconstruction using the deep inferior epigastric artery perforator flap. Before each angiogram, stereotactic fiducials were placed on the planned flap outline. The radiologist reviewed each preoperative angiogram to estimate the volume, and thus, weight of the flap. These estimated weights were compared with the actual intraoperative weights. Results: The average estimated weight was 99.7% of the actual weight.

Upon the autopsy, pigs were extubated and tubes were stored AZD6738 mouse at −80 °C for subsequent analysis. Then, to prevent any disruption of the biomatrix and impairment of bacterial viability, prior microscopic analyses, the ETTs were slowly unfrozen up to room temperature. The ETT exterior surface was cleaned with sterile gauzes and decontaminated through careful rinsing with 80% alcohol and saline solution. Using strict aseptic technique, two 1-cm-long sections of the distal dependent part of the ETT were excised

(Fig. 1). A 1-cm cross-section of ETT was immersed in a 1 mL phosphate buffer solution (PBS), stained with live/dead® BacLight kit™ (BacLight kit™; Invitrogen, Barcelona, Spain) for 15 min protected from the light, and then rinsed with PBS. The staining conditions were as follows: 1.5 μL of SYTO® 9 (stock 3.34 mM DMSO) and 1.5 μL propidium Palbociclib nmr iodide (stock 20 mM DMSO) in 1 mL PBS. During CLSM imaging, SYTO® 9 emits green fluorescence and is used to identify living microorganisms with intact membrane whereas propidium iodide (PI) emits red fluorescence and stains dead bacteria with damaged membrane. A Leica TCS SP5 laser scanning confocal system (Leica Microsystems Heidelberg GmbH, Manheim, Germany) equipped with a DMI6000 inverted microscope and a 20xPL APO numerical

aperture 0.7 objective were used. SYTO® 9 and PI images were acquired sequentially using 488-, 561-nm laser lines, an acousto optical beam splitter and emission detection ranges 500–550, 4-Aminobutyrate aminotransferase 570–620 nm, respectively. The confocal pinhole set at 1 Airy units. Pixel size was 160 nm. All samples and slides were coded to ensure that the image acquisition and measurements were blinded. The first author and an experienced CLSM facility manager made all observations and pictures. We analyzed 127 CLSM images (69 for the control, 37 for the linezolid, and 21 for the vancomycin group). Biofilm

viability was computed using image j software (Wayne Rasband, NIH). Regions of interest of each image were drawn by the operator to select all bacterial aggregates and exclude areas of eukaryotic cells; selection of these regions was based on cell size, morphology, and overall consistency of these factors within the area. Then, to select and independently measure the areas of live and dead bacteria, threshold limits were set for SYTO® 9 and PI channels, respectively. Only thresholded pixels were included in area measurements. For each image, we measured total area of bacteria (comprising live and dead bacteria), area of live bacteria (green), and dead bacteria (red) to evaluate differences in bacterial presence and viability among groups of treatment. We quantified the ratio between the total area of bacteria and the area of image examined, expressed as percentage. The live/dead bacterial ratio was calculated as the ratio between the area of live bacteria and the area of dead bacteria.

Tumour necrosis factor-related apoptosis-inducing ligand has an intricate receptor system comprising

four distinct membrane receptors, designated TRAIL-R1, TRAIL-R2, TRAIL-R3 and TRAIL-R4. Of these receptors, only TRAIL-R1 and TRAIL-2 transmit the apoptotic signal. These two receptors belong to a subgroup of the TNF receptor family, the so-called death receptors, and contain the hallmark intracellular death domain (DD). This DD is critical for apoptotic signalling by death receptors. Tumour necrosis factor-related apoptosis-inducing ligand activates the extrinsic pathway of apoptosis by binding to TRAIL-R1 and/or CT99021 TRAIL-R2 (Figure 1), whereupon the adaptor protein Fas-associated

death domain and initiator caspase-8 are recruited to the DD of these receptors. Assembly of this so-called death-inducing signalling complex leads to the sequential activation of initiator and effector caspases, and ultimately results in apoptotic cell death. In certain cells, the execution of apoptosis by TRAIL further relies on an amplification loop via the intrinsic mitochondrial pathway of apoptosis. The mitochondrial pathway of apoptosis is a stress-activated pathway, e.g. upon radiation, and hinges on the depolarization of the mitochondria, leading to release of Obeticholic Acid supplier a variety of pro-apoptotic factors into the cytosol (Figure 2). Ultimately, this also triggers effector caspase activation and apoptotic cell death. This mitochondrial release of pro-apoptotic factors is tightly controlled by the Bcl-2 family of pro- and anti-apoptotic proteins [14]. In the case of TRAIL receptor signalling the Bcl-2 homology (BH3) only protein Bid is cleaved into a truncated form (tBid) by active caspase-8. Truncated Bid subsequently activates the mitochondrial pathway. TRAIL-R3 is a glycosylphosphatidylinositol-linked

receptor that lacks an intracellular domain, whereas TRAIL-R4 only Digestive enzyme has a truncated and non-functional DD. The latter two receptors are thought to function as decoy receptors that modulate TRAIL sensitivity; however, the mechanism underlying this decoy function is not yet elucidated. Evidence suggests that TRAIL-R3 binds and sequesters TRAIL in lipid membrane microdomains. TRAIL-R4 appears to form heterotrimers with TRAIL-R2, whereby TRAIL-R2-mediated apoptotic signalling is disrupted. TRAIL-R4 might activate nuclear factor kappa B, although conflicting evidence concerning activation of nuclear factor kappa B exists [15,16]. Of note, TRAIL also interacts with the soluble protein osteoprotegerin, although the exact consequence of this interaction remains to be clarified.

Transthoracic echocardiography revealed no apparent vegetation. As we continued administering Vancomycin, swollen and reddened skin turned normal, but MRSA was positive on blood culture. We changed antibiotics, Vancomycin to Daptomycin. By changing antibiotics, blood culture turned negative. After administered antibiotics for 4 weeks, she was discharged and moved to another hospital to receive rehabilitation. Conclusions: Sometimes MRSA forms a biofilm. Vancomycin

doesn’t permeate a biofilm through inside easily. Daptomycin, however, penetrate through inside Selleck BMS-777607 and show antibacterial activity. In our case, successful treatment was done with Daptomycin. Daptomycin is one of the choice to treat graft infection by MRSA when it is intractable. 274 A CASE REPORT OF 2 SUCCESSFUL PREGNANCY OUTCOMES IN A FEMALE WITH END STAGE RENAL FAILURE SECONDARY TO FOCAL SEGMENTAL GLOMERULOSCLEROSIS S AGGARWAL1, S ROXBURGH1, A MATHER1, S MCGINN1, S SEEHO2, T NIPPITA2, M BROWN3 1Renal Medicine, Royal North Shore Hospital, St Leonards, NSW; 2Obstetrics and Gynaecology, Royal North Shore Hospital, St Leonards, NSW; 3Renal Medicine, St George Hospital, Kograh, NSW,

Australia Background: Successful pregnancy outcomes have been increasingly reported in patients with end stage kidney disease (ESKD) with improved haemodialysis regimes. We report 2 successful pregnancies in a 32 year old female with ESKD on chronic haemodialysis. Case Report: Our SB-3CT patient developed ESKD secondary to focal segmental glomerulosclerosis (FSGS) that was treated unsuccessfully with cyclophosphamide and steroids and progressed to dialysis by age PLX4032 20. She subsequently had a renal transplant aged 25 with disease recurrence resulting

in a return to nocturnal haemodialysis within 12 months. In 2009 she conceived and was managed with extended dialysis hours (36 hours/week with an average urea of 6 mmol/L) and correction of anaemia with increased dose of erythropoietin stimulating agents. At 33 + 6/40 gestation she developed preterm premature rupture of membranes (PPROM). She delivered a 2.3 kg male who developed severe nephrotic syndrome which resolved spontaneously by day 30. Genetic testing of both the mother and child did not reveal a familial or genetic form of FSGS. In 2012 she successfully progressed with a pregnancy after 2 miscarriages at 8/40 gestation. She remained on haemodialysis for 36 hours/week with an average urea of 4–6 mmol/L and a haemaglobin greater than 95 g/L. At 28 + 4/40 gestation she developed PPROM and went into spontaneous labour at 34 + 3/40 gestation. She delivered a 1.7 kg male with no evidence of nephrotic syndrome. Conclusions: This case supports the literature showing that extended hours of haemodialysis and correction of anaemia can preserve fertility and allow successful pregnancy outcomes in women on haemodialysis.

“Supermicrosurgical side-to-end (S-E) lymphaticovenular anastomosis (LVA) is the most favorable anastomotic configuration for the treatment of lymphedema because it creates Ku-0059436 datasheet antegrade and retrograde lymph flow while preserves the native lymph flow. However, it is technically demanding and its successful performance has been limited only to the experienced LVA surgeons.

This study aimed to evaluate the applicability of parachute technique in S-E LVA and its potential in decreasing the technical complexity of the procedure. Between April

2010 and July 2011, S-E LVAs were performed in 14 patients with bilateral lower limb lymphedema with either the conventional technique or the parachute technique. To exclude interoperator variability of LVAs, only limbs in which S-E LVAs performed by one surgeon were included. Torin 1 cost Feasibility, anastomotic patency, operative times, and treatment efficacy of both techniques were retrospectively compared. Thirty-seven S-E LVAs were performed by the surgeon; 17 LVAs with parachute technique in seven limbs and 20 LVAs with the conventional technique in seven limbs. Both groups demonstrated 100% anastomotic patency. Time required to perform the S-E anastomosis using the parachute technique was significantly shorter than when the conventional technique was used (8.6 ± 3.7 vs. 11.3 ± 3.1 minutes, P = 0.025). Both groups showed similar postoperative reduction in lymphedema indices (19.9 ± 8.2 vs. 18.9 ± 10.0, P = 0.841). Conclusions: The parachute technique simplifies the supermicrosurgical S-E LVA while maintaining

efficacy comparable to the conventional technique. © 2014 Wiley Periodicals, Inc. Microsurgery, 2014. “
“In this study, 6-phosphogluconolactonase the surgical outcomes of 32 patients with ulnar nerve injuries in the Guyon canal are presented. Outcomes were analyzed in relation to various factors such as age, surgical timing, zone of injury, and type of nerve reconstruction. Between 1990 and 2007, 32 patients with injury in Guyon canal were managed surgically. Twelve patients had ulnar nerve injury proximal to its bifurcation (zone I); 14 patients had isolated motor branch injury (zone II); and six patients had isolated sensory branch injury (zone III). End-to-end repair was achieved in 12 (38%) of 32 patients, while nerve grafting was performed in 20 (62%) cases. The mean follow-up period was 22 months. Good and excellent motor function was restored in 25 (96%) of 26 cases with motor branch injury. Good and excellent sensory results were achieved in 15 (83%) of 18 cases with sensory branch injury.

In addition to GM-CSF and MIP-1β (not measured in healthy volunteers after low doses AndoSan™ consumption), in patients with IBD, IL-1β, IL-2, IL-6, IL-17 and G-CSF were detected in reduced concentrations after mushroom intake both among healthy volunteers and patients. Thus, both pro-inflammatory cytokines (IL-1β, IL-6) and chemokines (IL-8, MIP-1β, MCP-1, GM-CSF, G-CSF) were downregulated by AndoSan™ in these patients with IBD. The three cytokines with the most marked reduction in LPS-stimulated blood from these

patients were MIP-1β, IL-1β and IL-6. Chemokine MIP-1β belongs to the family of macrophage inflammatory 1 proteins, which orchestrate acute and chronic inflammatory responses at sites of injury or infection mainly by recruiting pro-inflammatory Staurosporine supplier cells [32]. selleck chemicals llc Recently, an unselective increase in chemokine expression in mucosa has been demonstrated by immunohistochemistry

among patients with UC and CD. Such studied chemokines include MIP1-β, MCP-1 and IL-8 [19], which were reduced in collected blood from patients with UC (MIP1-β, MCP-1) and CD (MIP1-β, IL-8). IL-6 in the intestinal mucosa is synthesized by mononuclear cells [21, 24], and it is elevated in serum in both UC [25] and CD [24]. We observed a considerable decline in this cytokine (Fig. 2B) in patients with UC after consumption of the mushroom extract. Similar to our study (Tables 1–3), increased serum levels of IL-1β are seldom detected [24], but IL-1β levels are elevated [20, 33, 34] in intestinal lesions in both UC and CD. Interestingly, levels of IL-1β in LPS-stimulated blood declined in both diseases, again pointing to a net anti-inflammatory effect of AndoSan™. The hitherto unreported reduction in pleiotropic IL-17 (Fig. 3F) in patients with CD is intriguing [35]. Because IL-17 will both convey a host defensive mechanism to various extracellular bacterial Sclareol infections and pathogenic involvement in autoimmune disease, a reduced concentration of this cytokine may dampen these inflammatory reactions. The general tendency in patients with UC and CD was that cytokine levels

were either significantly or insignificantly reduced after 12 days of mushroom consumption. Thus, the lack of significant reduction in concentrations especially for cytokines TNF-α, IFN-γ and IL-6 (CD) could be because of the limited number of patients included in each IBD group (type II error). For cytokines IL-4, IL-5, IL-7 and IL-13 in patients with IBD, there were no striking alterations in their concentrations throughout the experimental period. None of the Th2 cytokines (IL-4, -5, -13) potentially relevant for UC seemed to be initially elevated or modulated by AndoSan™, whilst IL-2 was the only Th1 cytokine that was reduced after AndoSan™ ingestion in patients with CD. According to the Th2/Th1 dichotomy [36], one could also have anticipated an inverse increase in Th2 and Th1 cytokines in UC and CD, respectively.
