IL-2/Interleukin-2

Rat IgG

IL-2 recombinant protein. Placenta Cellular

Synthetic peptide corresponding to human IL-2 protein. Lymphokines secreted by activated lymphocytes include proteins such as interleukin-2. This protein is secreted primariry by helper T cells that have been activated through the T cell receptor complex or by other mitogens. Cells targeted by IL-2 include activated T helper and cytotoxic T cells inducing their proliferation. The secretion of IL-2 can also act as a growth factor for B cells. The transcription factor NFAT has been shown to play a major role in the regulation of IL-2 transcription and correlates to an age-related decline in the expression of IL-2.
