and pathogen chronicity. However, the mechanisms that underpin the development of these
regulatory cells, especially in the context of ongoing antigen exposure, have remained
obscure. To address this knowledge gap, we undertook a comprehensive functional,
phenotypic, and transcriptomic analysis of interleukin (IL)-10-producing CD4+ T cells
induced by chronic infection with murine cytomegalovirus (MCMV). We identified these cells …
