Abstract:The differentiation of CD4+ T cell subsets in response to infection has been studied extensively, however the epigenetic programs that regulate these processes remain poorly understood. Active demethylation by tet methylcytosine dioxygenases of CpG dinucleotides within DNA is a key component of epigenetic programing that promotes lineage specific gene expression and contributes to cellular differentiation and function. Here we report that Tet2 acts to restrict the differentiation of T follicular helper (Tfh) c… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
