Function of T helper cells: Antigen presenting cells ( APCs ) present antigen on their Class II MHC molecules ( MHC2 ). (wikidoc.org)
Class II MHC proteins are generally only found on the surface of professional antigen-presenting cells (APCs). (wikidoc.org)
Some APCs also bind native (or unprocessed) antigens to their surface, such as follicular dendritic cells , but unprocessed antigens do not interact with T cells and are not involved in their activation. (wikidoc.org)
