Spatial and functional heterogeneity of follicular helper T cells in autoimmunity.

Spatial and functional heterogeneity of follicular helper T cells in autoimmunity. Curr Opin Immunol. 2019 Jul 30;61:1-9 Authors: Seth A, Craft J Abstract Follicular helper T cells provide signals that promote B cell development, proliferation, and production of affinity matured and appropriately isotype switched antibodies. In addition to their classical locations within B cell follicles and germinal centers therein, B cell helper T cells are also found in extrafollicular spaces - either in secondary lymphoid or non-lymphoid tissues. Both follicular and extrafollicular T helper cells drive autoantibody-mediated autoimmunity. Interfering with B cell help provided by T cells can ameliorate autoimmune disease in animal models and human patients. The next frontier in Tfh cell biology will be identification of Tfh cell-specific pathogenic changes in autoimmunity and exploiting them for therapeutic purposes.

CONCLUSIONS: TAK does co-occur with IBD, AS and less frequently with BS in about 1/5 of the patients, at least in a hospital setting. There is no clear temporal pattern. The high prevalence of inflammatory back pain in the dorsal spine in TAK needs further scrutiny. PMID: 31969224 [PubMed - as supplied by publisher]

CONCLUSIONS: In our cohort, the prevalence of serodiscordant SSc patients was low. They differed from their counterparts in some clinical manifestations. The management of patients with SSc should be guided by both serology and cutaneous subtype. PMID: 31969223 [PubMed - as supplied by publisher]

Authors: Gao N, Cui W, Zhao LM, Li TT, Zhang JH, Pan LL Abstract OBJECTIVES: Takayasu's arteritis (TAK) involves inflammatory vasculitis of large vessels and mainly affects the aorta and its major branches. Abnormal immunity may play a vital role in TAK pathogenesis. Regulatory T cells (Treg cells) are important for peripheral tolerance, but under certain conditions Treg cells can differentiate into Th-like cells that have lost immune suppressive function and promote the development of autoimmune diseases. The role of Th-like Treg cells in TAK is unclear and this study aims to investigate the function of Th-like Tr...

Sphingosine 1-phosphate (S1P) receptor modulators are being developed to treat autoimmune-mediated diseases, including ulcerative colitis (UC) and Crohn ’s disease (CD). Amiselimod (AMS), a second-generation S1P receptor modulator, was developed to reduce bradycardia associated with other S1P receptor modulators, including fingolimod.

Anti-TNF agents are an established treatment modality for ulcerative colitis (UC); however, as many as 30% of patients do not respond to anti-TNF agents, and almost 50% of responders lose clinical benefits after a year of treatment. Furthermore, numerous safety concerns are associated with long-term use of anti-TNF agents. An alternative treatment in development for autoimmune-mediated diseases, including Crohn ’s disease (CD) and UC, are sphingosine 1-phosphate receptor modulators such as amiselimod (AMS).

Anti-microbial antibodies have been found useful for diagnosis of Crohn ’s disease (CD) and Sjogren’s syndrome (Sjo). These antibodies are also elevated in other autoimmune disease such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and multiple sclerosis (MS). The prevalence of these antibodies in the normal healthy population is unknown. We set t o survey the normal population for these anti-microbial antibodies in comparison with Crohn’s disease and others. Totally 288 blood samples from the donor units of the leukocyte-reduced red blood cells from the American Red Cross were examined...

Intestinal fungal communities are perturbed in several autoimmune diseases and have been shown to influence disease outcome. We have shown that intestinal resident CX3CR1+ mononuclear phagocytes (MNPs) can sense gut fungi and are crucial for the initiation of immune responses both locally and at distant sites. These results suggest that recognition of fungi by gut phagocytes might be involved in the pathogenesis of immune-related diseases such as IBD. Despite the identification of a few molecules involved in the recognition and immunity to intestinal fungi the cellular mechanisms governing the initiation and regulation of ...

Under Inflammatory bowel disease (IBD), autoantibody-type VII collagen complex can induce autoimmune reaction and continue with the inflammation. Here, we introduced synthetic 19 amino acid sequenced peptide termed as NIPEP-IM-0127 that inhibits autoantibody-type VII collagen complex formation. The NIPEP-IM-0127 was further formulated for oral administration. Primary function of NIPEP-IM-0127 selectively localizes to wound gut barrier and masks exposed type VII collagen, which is the starting of autoimmune reaction.
