Anti-neutrophil cytoplasmic autoantibodies (ANCA) -associated (AAV) is an autoimmune disease characterized by inflammation and necrosis of blood vessel walls, which is accompanied by the presence of ANCA antibodies in serum. AAV includes granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangiitis (EGPA). The frequency of circulating MAIT cells is lower in patients with AAV compared to HCs, especially in MPA and GPA ( 56). MAIT cells in peripheral blood from AAV patients in the acute and remission phases exhibit an activated phenotype as judged by their increased expression of CD69 ( 57). The frequency of circulating MAIT cells that produce IFN-γ is increased in MPA and GPA patients, while the frequency of TNF and IL-17-producing MAIT cells is similar in AAV patients compared to controls ( 57).

Ankylosing spondylitis (AS) is a chronic inflammatory rheumatic disease characterized by abnormal ossification and ankylosis affecting the spine and sacroiliac joints. Peripheral blood MAIT cell frequency and number are reduced in AS patients compared with HCs; however, MAIT cell frequency does not correlate with disease activity ( 47, 51, 52). The results obtained by Gracey et al. show that the level of CD69 of blood MAIT cells in AS patients is equivalent to that in HCs, while Hayashi et al. have found that CD69 expression on circulating MAIT cells correlates with the Ankylosing Spondylitis Disease Activity Score in patients with AS ( 47, 51). The discrepancy may be due to some factors, such as different disease stages and different treatments. MAIT cells are enriched in synovial fluid with high expression of CCR6. There is a higher percentage of IL-17 + and IL-22 + MAIT cells and a lower percentage IFN-γ + MAIT cells in the blood of AS patients; in the paired synovial fluid of AS patients, TNF + and IFN-γ + MAIT cells are decreased, and the granzyme B + and IL-17 + MAIT cell frequencies are increased ( 47, 52). Furthermore, IL-17 elevation in circulating MAIT cells of AS patients depends on priming with IL-7 but not IL-23 or MR1-presenting antigens ( 47).

PMID 35058274. S2CID 246081888. Many of us have experienced theissues caused by the need to share accurate information, at speed, often with many partners, during an emergency incident. Even today, the solution for many organisations is to make a phone call. This ties-up a control roomoperator at both ends and, even with direct lines, it can cause queues and further delays. Some organisations benefit from direct, machine to machine, data communication which helps but still requires many links to share information with more than one partner. Harriff, M. J. et al.
