IL-7 reverses NK1+ T cell-defective IL-4 production in the non-obese diabetic mouse.

abstract：:We have previously shown that the occurrence of CD45RA+ adult mouse thymocytes is strain-dependent, e.g. constituting approximately 0.6% in C57BL/Icrf and approximately 2.5% in BALB/c (Huby, R. and Goff, L., 1992. Eur. J. Immunol. 22:1659). Here we show that irrespective of strain, the thymus contains approximately 0....

abstract：:The interleukin 2 receptor (IL-2R) is composed of at least two polypeptides--a 55 kd protein (the L chain, p55, or alpha chain) and a 75 kd protein (the H chain, p75 or beta chain). The high-affinity binding of IL-2 results in the formation of a ternary complex consisting of IL-2 and the L and H chains. We found that ...
