Abstract:Intrathymic T lymphocyte differentiation proceeds from complex interactions between prothymocytes of bone marrow origin and cells of the thymic stroma, epithelial cells and "acessory" cells (macrophages and/or interdigitating cells). The present paper describes the role of the accessoty cell compartment in this intrathymic process. Acessory cells produce factors which are involved in thymocyte proliferation (interleukin 1, prostaglandins, deoxynucleosides). Cell-cell interaction between "accessory" cells and t… 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.
