Since T cells express diverse sex steroid hormone receptors, they might be a good model to evaluate the effects of sex steroid hormones on immune modulation. Porcine testicular extract contains several sex steroid hormones and may be useful to study the effects of sex steroid hormones during T cell activation. We have examined the effects of the porcine(More)
Cytotoxic T lymphocyte-associated antigen-4 (CTLA-4; CD152) is a transmembrane protein that is structurally similar to CD28. As CTLA-4 has a much higher binding affinity to B7 than CD28, several approaches using soluble CTLA-4 have been tried to down-regulate T cell activity by blocking the interaction between CD28 and B7. We constructed soluble rhesus(More)
