T cells, the next big target in axSpA?
Arthritis &Rheumatology, Accepted Article.Axial spondyloarthritis (axSpA) is a chronic inflammatory disease characterized by complex immune dysregulation, with T cells playing a central role in its pathogenesis. In this review we synthesize current knowledge on diverse T cell subsets in axSpA, their pathogenic mechanisms, and emerging therapeutic strategies targeting these cells.

The role of mucosal associated invariant T cells in antimicrobial immunity
Frontiers in Immunology, 2015 Mucosal associated invariant T (MAIT) cells are an innate-like T cell subset prevalent in humans and distributed throughout the blood and mucosal sites. Human MAIT cells are defined by the expression of the semi-invariant TCRα chain TRAV1-2/TRAJ12/20/33 ...

Mucosal delivery of tuberculosis vaccines: a review of current approaches and challenges. [PDF]
, 2019 Introduction: Tuberculosis (TB) remains a major health threat and it is now clear that the current vaccine, BCG, is unable to arrest the global TB epidemic. A new vaccine is needed to either replace or boost BCG so that a better level of protection could

International Journal of Cancer, EarlyView.What's New? Colorectal cancer (CRC) is increasingly complicated by drug‐resistant tumors that limit the effectiveness of anticancer therapies. Because resistance mechanisms vary among patients and can evolve over time, personalized treatment strategies are needed.

MAIT cells launch a rapid, robust and distinct hyperinflammatory response to bacterial superantigens and quickly acquire an anergic phenotype that impedes their cognate antimicrobial function: Defining a novel mechanism of superantigen-induced immunopathology and immunosuppression [PDF]
, 2017 Superantigens (SAgs) are potent exotoxins secreted by Staphylococcus aureus and Streptococcus pyogenes. They target a large fraction of T cell pools to set in motion a "cytokine storm" with severe and sometimes life-threatening consequences typically ...

Interdisciplinary Medicine, EarlyView.In ankylosing spondylitis‐acute anterior uveitis (AS‐AAU), trained immunity monocytes (Mono‐TI) differentiate into macrophages in the eye, retaining trained immunity features. Mono‐TI cells secrete pro‐inflammatory cytokines and chemokines, including IL‐1β, TNF‐α, and CCL3.

Japanese Journal of Clinical Immunology, 2012 Mucosal associated invariant T (MAIT) cells are restricted by a nonpolymorphic MHC-related molecule-1 (MR1), and express an invariant TCRα chain: Vα7.2-Jα33 in humans and Vα19-Jα33 in mice. MAIT cells are selected in the thymus, but, interestingly, MAIT cells require B cells as well as commensal flora for their peripheral expansion.

Immunity, 2016 Mucosal-associated invariant T (MAIT) cells recognize microbial non-peptidic antigens presented by non-classical MHC MR1. In this issue of Immunity, Gherardin et al. (2016) show co-crystal structures of MR1 complexed to T cell receptors (TCRs) from two classes of MAIT-type cells.
