CD28 is the quintessential costimulatory molecule expressed on CD4(+) and CD8(+) T cells. During chronic infections and the normal aging process, CD28 expression is lost, compromising the functional activity of T cells. CD28 loss is promoted by replicative stress, particularly in the presence of tumor necrosis factor-alpha, owing to an inoperative CD28 initiator element. It is currently unknown...
To analyze the roles of interleukin-12 (IL-12) and the IL-12-dependent Th1 response in resistance to Cryptococcus neoformans, we have established a chronic infection model in wild-type mice and in mice with targeted disruptions of the genes for the IL-12p35 and IL-12p40 subunits (IL-12p35(-/-) and IL-12p40(-/-) mice, respectively) as well as in mice with a targeted disruption of the IL-4 gene. ...
