Oncostatin M Receptor Type II Knockout Mitigates Inflammation and Improves Survival from Sepsis in Mice. Biomedicines 2023; 11:biomedicines11020483. [PMID: 36831019 PMCID: PMC9953488 DOI: 10.3390/biomedicines11020483] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Revised: 01/27/2023] [Accepted: 01/31/2023] [Indexed: 02/11/2023] Open
Abstract
Sepsis remains one of the leading causes of death worldwide. Oncostatin M (OSM), an interleukin (IL)-6 family cytokine, can be found at high levels in septic patients. However, little is known about its role in sepsis. This study aimed to determine if the genetic knockout of OSM receptor (OSMR) type II signaling would improve survival in a murine model of sepsis. Aged (>50 weeks) OSMR type II knockout (KO) mice and wild-type (WT) littermates received an intraperitoneal injection of fecal slurry (FS) or vehicle. The KO mice had better survival 48 h after the injection of FS than the WT mice (p = 0.005). Eighteen hours post-FS injection, the KO mice had reduced peritoneal, serum, and tissue cytokine levels (including IL-1β, IL-6, TNFα, KG/GRO, and IL-10) compared to the WT mice (p < 0.001 for all). Flow cytometry revealed decreased recruitment of CD11b+ F4/80+ Ly6chigh+ macrophages in the peritoneum of KO mice compared to WT mice (34 ± 6 vs. 4 ± 3%, PInt = 0.005). Isolated peritoneal macrophages from aged KO mice had better live E. coli killing capacity than those from WT mice (p < 0.001). Peritoneal lavage revealed greater bacterial counts in KO mice than in WT mice (KO: 305 ± 22 vs. 116 ± 6 CFU (×109)/mL; p < 0.001). In summary, deficiency in OSMR type II receptor signaling provided a survival benefit in the progression of sepsis. This coincided with reduced serum levels of pro-inflammatory (IL-1β, TNFα, and KC/GRO) and anti-inflammatory markers (IL-10), increased bacterial killing ability of macrophages, and reduced macrophage infiltration into to site of infection.

Abstract
Introduction Methotrexate (MTX) is the first-line drug for the treatment of rheumatoid arthritis (RA) in several countries. However, MTX has an extremely low solubility in water, and the side effects caused by its delivery mode restrict its curative effect. In this study, we designed a dissolving microneedles array (DMNA) containing MTX nanocrystals (MTX-NCs) (MTX-NC@DMNA) to improve the treatment of RA. DMNA-based drug delivery combines the advantages of patient compliance with the use of transdermal drug delivery systems and high-efficiency injection administration; thus, it can mitigate the side effects that result from current administration routes. Carrier-free and surfactant-free MTX-NCs were prepared to overcome bioavailability limitations and poor drug loading problems. Methods The MTX-NCs prepared by reverse solvent precipitation method was encapsulated in the DMNA. The morphology, mechanical properties, safety, stability and in vivo dissolution were evaluated, and its pharmacodynamic characteristics were assessed in a rat model of RA. Results The particle size of the MTX-NCs was 148.1 ± 10.1 nm. The MTX-NC@DMNA were found to be rigid enough to penetrate the skin and deliver the drug successfully. The results indicated effective skin recovery after removal of the DMNA. It was found that the MTX-NC@DMNA significantly reduced foot swelling in the rats and regulated the balance in the levels of related cytokines. It also reduced pathological damage to the synovium, joint, and cartilage, and effectively alleviated organ injury in the rats. Conclusion Transdermal administration of MTX-NC@DMNA may be an effective approach for treating RA.

Abstract
Inflammasome is a molecular platform that is formed in the cytosolic compartment to mediate host immune responses to infection and cellular damage. Inflammasome can activate caspase-1, leading to the maturation of two inflammatory cytokines interleukin 1β (IL-1β) and IL-18 and initiation of a proinflammatory form of cell death called pyroptosis. Among various inflammasome complexes, the NLRP3 inflammasome is by far the most studied inflammasome. NLRP3 inflammasome is a key factor in regulating host immune defense against infectious microbes and cellular damage. However, the dysregulated NLRP3 inflammasome activation also participates in the pathogenesis of many human disorders. NLRP3 inflammasome plays an important role in the pathogenesis of rheumatic disease such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), ankylosing spondylitis (AS), Sjögren's syndrome (SS), dermatomyositis/polymyositis (DM/PM), gout, and systemic sclerosis (SSc). For example, NLRP3 inflammasome has been found highly activated in synovial tissues and peripheral blood mononuclear cells from RA patients. In this paper, we will discuss the role of NLRP3 inflammasome in the pathogenesis of rheumatic disease.

Abstract
Skeletal system has been considered a highly dynamic system, in which bone-forming osteoblasts and bone-resorbing osteoclasts go through a continuous remodeling cycle to maintain homeostasis of bone matrix. It has been well acknowledged that interferons (IFNs), acting as a subgroup of cytokines, not only have crucial effects on regulating immunology but also could modulate the dynamic balance of bone matrix. In the light of different isoforms, IFNs have been divided into three major categories in terms of amino acid sequences, recognition of specific receptors and biological activities. Currently, type I IFNs consist of a multi-gene family with several subtypes, of which IFN-α exerts pro-osteoblastogenic effects to activate osteoblast differentiation and inhibits osteoclast fusion to maintain bone matrix integrity. Meanwhile, IFN-β suppresses osteoblast-mediated bone remodeling as well as exhibits inhibitory effects on osteoclast differentiation to attenuate bone resorption. Type II IFN constitutes the only type, IFN-γ, which exerts regulatory effects on osteoclastic bone resorption and osteoblastic bone formation by biphasic ways. Interestingly, type III IFNs are regarded as new members of IFN family composed of four members, including IFN-λ1 (IL-29), IFN-λ2 (IL-28A), IFN-λ3 (IL-28B) and IFN-λ4, which have been certified to participate in bone destruction. However, the direct regulatory mechanisms underlying how type III IFNs modulate the metabolic balance of bone matrix, remains poorly elucidated. In this review, we have summarized functions of IFN family during physiological and pathological conditions and described the mechanisms by which IFNs maintain bone matrix homeostasis via affecting the osteoclast-osteoblast crosstalk. In addition, the potential therapeutic effects of IFNs on inflammatory bone destruction diseases such as rheumatoid arthritis (RA), osteoarthritis (OA) and infectious bone diseases are also well displayed, which are based on the predominant role of IFNs in modulating the dynamic equilibrium of bone matrix.

Abstract
Cell death is ascribed as an essential biological process that is fundamental for the development of an organism along with its survival. The procedure comprises of apoptosis and pyroptosis. Pyroptosis is a programmed procedure for cell death which is inflammatory in nature and this pathway gets activated via human caspase-4, human caspase-11 and human caspase-5. The activation of this process leads to release of pro-inflammatory mediators including cytokines, alarmins, IL-18 and IL-1β. The pro-inflammatory mediators released via interaction of intracellular kinases direct the development of Rheumatoid arthritis. Rheumatoid arthritis is characterized as disorder/disease that is auto-immune and chronic in nature. It involves erosions in marginal bone along with articular cartilage which is responsible for joint destruction. The cytokine along with its complex network is responsible for inflammation. The process of pyroptosis is linked with the destruction of plasma membrane, that releases these mediators and excessive release of these mediators is linked with rheumatoid arthritis.

Abstract
Animal venoms comprise a complex mixture of components that affect several biological systems. Based on the high selectivity for their molecular targets, these components are also a rich source of potential therapeutic agents. Among the main components of animal venoms are the secreted phospholipases A2 (sPLA2s). These PLA2 belong to distinct PLA2s groups. For example, snake venom sPLA2s from Elapidae and Viperidae families, the most important families when considering envenomation, belong, respectively, to the IA and IIA/IIB groups, whereas bee venom PLA2 belongs to group III of sPLA2s. It is well known that PLA2, due to its hydrolytic activity on phospholipids, takes part in many pathophysiological processes, including inflammation and pain. Therefore, secreted PLA2s obtained from animal venoms have been widely used as tools to (a) modulate inflammation and pain, uncovering molecular targets that are implicated in the control of inflammatory (including painful) and neurodegenerative diseases; (b) shed light on the pathophysiology of inflammation and pain observed in human envenomation by poisonous animals; and, (c) characterize molecular mechanisms involved in inflammatory diseases. The present review summarizes the knowledge on the nociceptive and antinociceptive actions of sPLA2s from animal venoms, particularly snake venoms.

Abstract
BACKGROUND Arthritis is a set of inflammatory conditions that induce aching, stiffness, swelling, pain and may cause functional disability with severe consequences to the patient's lives. These are multi-mediated pathologies that cannot be effectively protected and/or treated. Therefore, the aim of this study was to establish a new model of acute arthritis, using a Lys49-PLA2 (Bothrops asper myotoxin II; MT-II) to induce articular inflammation. METHODS The articular inflammation was induced by MT-II (10 μg/joint) injection into the left tibio-tarsal or femoral-tibial-patellar joints. Cellular influx was evaluated counting total and differential cells that migrated to the joint. The plasma extravasation was determined using Evans blue dye. The edematogenic response was evaluated measuring the joint thickness using a caliper. The articular hypernociception was determined by a dorsal flexion of the tibio-tarsal joint using an electronic pressure-meter test. The mediators involved in the articular hypernociception were evaluated using receptor antagonists and enzymatic inhibitors. RESULTS Plasma extravasation in the knee joints was observed 5 and 15 min after MT-II (10 μg/joint) injection. MT-II also induced a polymorphonuclear cell influx into the femoral-tibial-patellar joints observed 8 h after its injection, a period that coincided with the peak of the hyperalgesic effect. Hyperalgesia was inhibited by the pretreatment of the animals with cyclooxygenase inhibitor indomethacin, with type-2 cyclooxygenase inhibitor celecoxib, with AACOCF3 and PACOCF3, inhibitors of cytosolic and Ca2+-independent PLA2s, respectively, with bradykinin B2 receptor antagonist HOE 140, with antibodies against TNFα, IL-1β, IL-6 and CINC-1 and with selective ET-A (BQ-123) and ET-B (BQ-788) endothelin receptors antagonists. The MT-II-induced hyperalgesia was not altered by the lipoxygenase inhibitor zileuton, by the bradykinin B1 receptor antagonist Lys-(Des-Arg9,Leu8)-bradykinin, by the histamine and serotonin antagonists promethazine and methysergide, respectively, by the nitric oxide inhibitor LNMMA and by the inhibitor of matrix 1-, 2-, 3-, 8- and 9- metalloproteinases GM6001 (Ilomastat). CONCLUSION These results demonstrated the multi-mediated characteristic of the articular inflammation induced by MT-II, which demonstrates its relevance as a model for arthritis mechanisms and treatment evaluation.

Abstract
AIM To assess serum type III or lambda (λ) interferons (IFN) levels and its clinical and laboratory associations in rheumatoid arthritis (RA). METHODS A cross-sectional study including 43 patients with RA (86% females; age 45.3 ± 10.3 years) and 43 healthy individuals was performed. Clinical data including disease activity, acute-phase reactants, rheumatoid factor and anticyclic citrullinated peptide (anti-CCP) antibodies were collected. Serum IFNλ1, IFNλ2, IFNλ3, CXCL8 and anti-mutated citrullinated vimentin (anti-MCV) antibody levels were measured. RESULTS Patients with RA had higher IFNλ1 (113.5 ± 118.6 pg/mL versus 55.9 ± 122.3 pg/mL; p < 0.0001) and IFNλ2 (245.4 ± 327.7 pg/mL versus 5.1 ± 11.0 pg/mL; p = 0.009) levels than controls, but not IFNλ3 levels. Notably, IFNλ1 levels were found to be higher in both patients with active disease (124.9 ± 135.9 pg/mL; p < 0.001) and quiescent disease (99.0 ± 93.7 pg/mL; p < 0.01), while IFNλ2 levels were higher only in patients with active disease (264.0 ± 356.1 pg/mL; p = 0.02). A noteworthy association between serum IFNλ1 levels and anti-MCV antibody titers (Spearman's rho coefficient 0.36, 95% CI 0.36 to 0.61; p = 0.02) was observed. CONCLUSION Serum IFNλ1 and IFNλ2 levels are abnormally elevated in patients with RA and the former are linearly associated with circulating anti-MCV antibody levels. These results may place type-III IFN as an attractive new therapeutic target in RA.

Abstract
Inflammation is an integral component of autoimmune arthritis. The balance of pathogenic T helper 17 (Th17) and protective T regulatory (Treg) cells can influence disease severity, and its resetting offers an attractive approach to control autoimmunity. We determined the frequency of Th17 and Treg in the joints of rats with adjuvant arthritis (AA), a model of rheumatoid arthritis (RA). We also investigated the impact of Celastrol, a bioactive compound from the traditional Chinese medicine Celastrus that can suppress AA, on Th17/Treg balance in the joints. Celastrol treatment reduced Th17 cells but increased Treg in the joints, and it inhibited Th17 differentiation but promoted Treg differentiation in vitro by blocking the activation of pSTAT3. Furthermore, Celastrol limited the production of Th17-differentiating cytokines and chemokines (CCL3, CCL5). Thus, Celastrol suppressed arthritis in part by altering Th17/Treg ratio in inflamed joints, and it should be tested as a potential adjunct/alternative for RA therapy.

Abstract
Chronic inflammatory diseases represent a heterogeneous group of conditions that can affect practically any organ or system. An increasing number of biologic agents have been developed to selectively target the cell populations and signaling pathways involved in chronic inflammation, including cytokines, monoclonal antibodies and engineered receptors. This approach has been remarkably successful in alleviating some of the signs and symptoms of refractory autoimmune diseases. The use of this therapeutic strategy is likely to increase with the introduction of biosimilar agents. The different nature of these biological products makes the comparison of their pharmaceutical and clinical characteristics difficult, including safety and potency and these issues may be particularly relevant in the case of biosimilars. In addition, the heterogeneity of autoimmune diseases and of autoimmune patients, further adds to the complexity of choosing the right drug for each patient and predicting efficacy and safety of the treatment. In this review, we summarize actual knowledge about current biological agents and their use in autoimmune diseases, with a special emphasis for rheumatoid arthritis, inflammatory bowel diseases and psoriasis. The purpose of this analysis is to address the most critical issues raised by the rapid advancements in this field over recent years, and to acknowledge the potentially valuable gains brought about by the increasing availability of these new biologic agents.

Abstract
Abatacept is approved for the treatment of moderate-to-severe active rheumatoid arthritis (RA) patients with inadequate response to one or more disease-modifying antirheumatic drugs (DMARDs), including methotrexate or a TNF antagonist, and can be used either as monotherapy or concomitantly with nonbiologic DMARDs. It can be administered either intravenously or subcutaneously. It has demonstrated to improve signs and symptoms of RA, physical function and health-related quality of life, and it inhibits radiographic progression of structural damage across a wide range of early and long-standing RA populations. The safety profile appears good and close to RA patients treated with nonbiologic DMARDs. Meta-analysis and real-world studies support these findings. This article reviews published data on clinical and radiographic efficacy as well as the safety of this drug, incorporating recent relevant information reported at scientific meetings.

Abstract
New treatments for rheumatoid arthritis (RA) continue to emerge to meet unsatisfied needs of a significant number of patients. The development of new, oral biologic therapy is a significant step forward, although these drugs will require further evaluation in clinical settings before their true potential is appreciated. This new, oral biologic therapy has mostly focused on inhibition of intracellular signaling. These mechanisms and the available studies regarding the efficacy and safety of specific drugs which interfere with these mechanisms are the subject of this article.

Abstract
Cervical carcinoma is the second most common cause of cancer deaths in women worldwide. Treatments have not changed for decades and survival rates for advanced disease remain low. An exciting new molecular target for the treatment of cervical squamous cell carcinoma (SCC), and possibly for SCCs at other anatomical sites, is the oncostatin M receptor (OSMR). This cell surface cytokine receptor is commonly copy number gained and overexpressed in advanced cervical SCC, changes that are associated with significantly worse clinical outcomes. OSMR overexpression in cervical SCC cells results in enhanced responsiveness to the major ligand oncostatin M (OSM), which induces several pro-malignant effects, including a pro-angiogenic phenotype and increased cell migration and invasiveness. OSMR is a strong candidate for antibody-mediated inhibition, a strategy that has had a major impact on haematological malignancies and various solid tumours such as HER2-positive breast cancers.

Abstract
Recent therapeutic advancements in understanding of molecular and cellular mechanisms of rheumatoid arthritis (RA) have highlighted the strategies that aim to inhibit the harmful effects of up-regulated cytokines or other inflammatory mediators and to inhibit their associated signaling events. The utility of cytokine as therapeutic targets in RA has been unequivocally demonstrated by the success of tumor necrosis factor (TNF)-α blockade in clinical practice. Partial and non-responses to TNF-α blocking agents, however, together with the increasing clinical drive to remission induction, requires that further therapeutic targets be identified. Numerous proinflammatory mediators with their associated cell signaling events have now been demonstrated in RA, including interleukin (IL)-1 and IL-12 superfamilies. Continued efforts are ongoing to target IL-6, IL-15 and IL-17 in clinical trials with promising data emerging. In the present review, we focus on IL-7, IL-18, IL-32 and IL-10 family of cytokines (IL-19, IL-20 and IL-22) as they are implicated in contributing to the pathogenesis of RA, which could be targeted and offer new therapeutic options for RA therapy. Recent evidences also suggest that multiligand receptor for advanced glycation end products (RAGE), several adipokines and various components of immune system play a critical role in the pathophysiology of RA; therefore we have also highlighted them as therapeutic targets for RA therapy. Components of subcellular pathways, involve in nuclear transcription factor (NF)-κB, mitogen-activated protein kinases (MAPKs) and the Janus kinase-signal transducer and activator of transcription (JAK-STAT) pathway have also been discussed and offer several novel potential therapeutic opportunities for RA.

Tissue transglutaminase mediates the pro-malignant effects of oncostatin M receptor over-expression in cervical squamous cell carcinoma. J Pathol 2013; 231:168-79.

Abstract
Oncostatin M receptor (OSMR) is commonly over-expressed in advanced cervical squamous cell carcinoma (SCC), producing a significantly worse clinical outcome. Cervical SCC cells that over-express OSMR show enhanced responsiveness to the major ligand OSM, which induces multiple pro-malignant effects, including increased cell migration and invasiveness. Here, we show that tissue transglutaminase (TGM2) is an important mediator of the ligand-dependent phenotypic effects of OSMR over-expression in SCC cells. TGM2 expression correlated with disease progression and with OSMR levels in clinical samples of cervical and oral SCC. TGM2 depletion in cervical SCC cells abrogated OSM-induced migration on fibronectin-coated surfaces and invasiveness through extracellular matrix, while ectopic expression of TGM2 increased cell motility and invasiveness. Confocal microscopy and co-immunoprecipitation assays showed that TGM2 interacted with integrin-α5β1 in the presence of fibronectin in cervical SCC cells, with OSM treatment strengthening the interaction. Importantly, integrin-α5β1 and fibronectin were also over-expressed in cervical and oral SCC, where levels correlated with those of OSMR and TGM2. This combined tissue and in vitro study demonstrates for the first time that stimulation of over-expressed OSMR in cervical SCC cells activates TGM2/integrin-α5β1 interactions and induces pro-malignant changes. We conclude that an OSMR/TGM2/integrin-α5β1/fibronectin pathway is of biological significance in cervical SCC and a candidate for therapeutic targeting.

Abstract
Interferon (IFN)-λ1 is a newly described cytokine that is known for its proinflammatory activity in viral infection and in cancer. Because recent studies indicated that IFN-λ can influence significantly the innate and adaptive immune response, we studied IFN-λ in a prototypic systemic autoimmune disease, rheumatoid arthritis (RA). It was found that RA patients had higher mRNA levels in PBMC and higher serum levels of IFN-λ1 in comparison with healthy matched controls and ankylosing spondylitis (AS) patients. Although there was no correlation between serum IFN-λ1 and RA autoantibodies, RA patients that presented knee joint involvement displayed higher serum IFN-λ1 than patients without knee joint involvement, suggesting that abnormally elevated IFN-λ1 levels in RA can associate with knee joint disease.

Abstract
Synovial angiogenesis is well recognized as participating in the pathogenesis of rheumatoid arthritis (RA) and has been regarded as a potential target for RA therapy. Previously, we have shown that norisoboldine (NOR) can protect joints from destruction in mice with collagen II-induced arthritis (CIA). Here, we investigate the effect of NOR on synovial angiogenesis in adjuvant-induced arthritis (AA) rats, and clarify the mechanisms in vitro. NOR, administered orally, significantly reduced the number of blood vessels and expression of growth factors in the synovium of AA rats. In vitro, it markedly prevented the migration and sprouting of endothelial cells. Notably, the endothelial tip cell phenotype, which is essential for the migration of endothelial cells and subsequent angiogenesis, was significantly inhibited by NOR. This inhibitory effect was attenuated by pretreatment with N-{N-[2-(3,5-difluorophenyl) acetyl]-(S)-alanyl}-(S)-phenylglycine tert-butyl ester, a Notch1 inhibitor, suggesting that the action of NOR was related to the Notch1 pathway. A molecular docking study further confirmed that NOR was able to promote Notch1 activation by binding the Notch1 transcription complex. In conclusion, NOR was able to prevent synovial angiogenesis in AA rats, which is a putatively new mechanism responsible for its anti-rheumatoid effect. The anti-angiogenesis action of NOR was likely achieved by moderating the Notch1 pathway-related endothelial tip cell phenotype with a potential action target of the Notch1 transcription complex.

Abstract
OBJECTIVES Insulin-like growth factor-1 (IGF-1) regulates several biological functions, and low plasma levels of IGF-1 are known to contribute towards the pathogenesis of rheumatoid arthritis (RA). In view of the biological significance of IGF-1, we investigated the association of RA with the polymorphism of a 192-bp allele which is cytosine-adenosine repeat located 1 kb upstream from the IGF-1 gene transcription site and is known to regulate serum IGF-1 levels. METHODS Blood samples were collected from 52 healthy controls (HC) and 68 RA patients to measure the levels of IGF-1 and to isolate genomic DNA. Polymorphism of the IGF-1 gene was examined using polymerase chain reaction (PCR). Disease severity, duration, and activity were recorded for all RA patients. RESULTS We observed that 97% of all the subjects who participated in this study showed the presence of a 192-bp allele of the IGF-1 gene. All healthy controls exhibited the presence of 192-bp wild-type allele. All non-carriers of the 192-bp allele were Arabs and had RA. Gender correlated significantly with allele frequencies as 14% of the male and only 2% of the female RA patients were non-carriers of 192-bp allele. Plasma IGF-1 levels were significantly lower (p < 0.01) in RA patients compared to HC, and all RA patients who were non-carriers of the 192-bp allele had a significantly high disease activity score. No correlation was found between the duration of RA and the presence or absence of this allele. CONCLUSIONS This study suggests a possible association of the IGF-1 gene polymorphism with developing RA, particularly in males as non-carriers of the 192-bp allele.

Abstract
There is now growing evidence that autoimmunity is the common trait connecting multiple clinical phenotypes albeit differences in tissue specificity, pathogenetic mechanisms, and therapeutic approaches cannot be overlooked. Over the past years we witnessed a constant growth of the number of publications related to autoimmune diseases in peer-reviewed journals of the immunology area. Original data referred to factors from common injury pathways (i.e. T helper 17 cells, serum autoantibodies, or vitamin D) and specific diseases such as multiple sclerosis, systemic lupus erythematosus, and rheumatoid arthritis. As an example, the issue of a latitudinal gradient in the prevalence and incidence rates has been proposed for all autoimmune diseases and was recently coined as geoepidemiology to suggest new environmental triggers for tolerance breakdown. The present article is aimed at reviewing the articles that were published over the past year in the major autoimmunity and immunology journals.

Abstract
IL-10 producing regulatory type 1 (Tr1) cells represents a subpopulation of CD4+ regulatory cells able to prevent in vitro bystander T-cell proliferation and to inhibit a wide range of inflammatory diseases in mice. Our aim was to evaluate the frequency and function of joint specific Tr1 cells in the peripheral blood of severe Rheumatoid Arthritis (RA) patients. The collagen II protein was chosen to isolate Tr1 cells specific for a joint antigen. We successfully isolated Tr1 clones from 9 out of 11 RA patients. We showed that cells from patients display the same phenotype and surface marker regulation as previously shown for human Tr1 cells, characterized by expression of markers of regulation (FoxP3, CD25) at the activated but not at the resting state. Importantly, cells from patients showed Tr1 cytokine secretion (IL-10 and IFN-γ) and immunosuppressive action on bystander T cell proliferation. Based on these results, we demonstrated that collagen II specific Tr1 cells can be isolated from the blood of severe refractory patients and that these cells are not altered in their phenotype and function.
