WebExpert Answer. QUESTION 9 Helper T cells (TH) are activated by binding to epitopes on molecules using their T cell receptor and coreceptor. Once activated, they can differentiate into either cells which stimulate cytotoxic T cells or cells which stimulate B cells. QUESTIONS Helper T cells (TH) are activated by binding to epitopes on v coreceptor. WebDQ2-and DQ8-mediated presentation of gluten peptides to CD4+ T cells is a key event in the pathogenesis of the disease. The association of celiac disease with these human leukocyte antigen (HLA) molecules is explained by a preferential binding of gluten peptides to these HLA molecules, although the actual data on this in the literature are scarce.
