CD28 delivers a costimulatory signal involved in antigen-specific IL-2 production by human T cells by Jenkins, MK, Taylor, PS, Norton, SD, Urdahl, KB

“…CD4+ T cells require two signals to produce maximal amounts of IL-2, i.e., TCR occupancy and an unidentified APC-derived costimulus. Here we show that this…”

Clonal anergy is induced in vitro by T cell receptor occupancy in the absence of proliferation by DeSilva, DR, Urdahl, KB, Jenkins, MK

“…Murine Th1 clones that receive signals through their TCR in the absence of APC-derived co-stimulatory signals do not produce IL-2 and instead become anergic,…”
