WebApr 13, 2024 · Signal inhibitory receptor on leukocytes-1 (SIRL-1) is an immune inhibitory receptor expressed on human myeloid cells. We previously showed that dendritic cell (DC)-driven Th17 cell differentiation of human naive CD4+ T cells requires presence of neutrophils, which is inhibited by SIRL-1 ligation. VSTM1-v2 is a soluble isoform of SIRL-1, … WebJul 19, 2024 · Activated (and differentiated) T cells that were previously activated by DCs can identify some of these B cells clones through the TCR-MHC interaction. The B cells process the antigens like DCs, so the resulting heterogeneity of the processed peptides means a fair chance a T cell will recognize it.
