Research articleCaspase-1 inhibitor regulates humoral responses in experimental autoimmune myasthenia gravis via IL-6- dependent inhibiton of STAT3
چکیده انگلیسی


- Caspase-1 inhibitor reduced follicular helper T cells, and suppressed germinal center response.
- Caspase-1 inhibitor increased follicular regulatory T cells and regulatory B cells.
- Caspase-1 inhibitor inhibited humoral immunity response in EAMG rats via suppressing IL-6-STAT3-Bcl-6 pathways.

We have previously demonstrated that Cysteinyl aspartate-specific proteinase-1 (caspase-1) inhibitor ameliorates experimental autoimmune myasthenia gravis (EAMG) by inhibited cellular immune response, via suppressing DC IL-1 β, CD4+ T and γdT cells IL-17 pathways. In this study, we investigated the effect of caspase-1 inhibitor on humoral immune response of EAMG and further explore the underlying mechanisms. An animal model of MG was induced by region 97-116 of the rat AChR α subunit (R97-116 peptide) in Lewis rats. Rats were treated with caspase-1 inhibitor Ac-YVAD-cmk intraperitoneally (i.p.) every second day from day 13 after the first immunization. Flow cytometry, western blot, immunofluorescence, and enzyme-linked immunosorbent assay (ELISA) were performed to evaluate the neuroprotective effect of caspase-1 inhibitor on humoral immune response of EAMG. The results showed that caspase-1 inhibitor reduced the relative affinity of anti-R97-116 IgG, suppressed germinal center response, decreased follicular helper T cells, and increased follicular regulatory T cells and regulatory B cells. In addition, we found that caspase-1 inhibitor inhibited humoral immunity response in EAMG rats via suppressing IL-6-STAT3-Bcl-6 pathways. These results suggest that caspase-1 inhibitor ameliorates EAMG by regulating humoral immune response, thus providing new insights into the development of myasthenia gravis and other autoimmune diseases therapies.
