Background
Rat IL-2 (Interleukin-2) is a 15–17 kDa glycoprotein and key T-cell growth factor primarily secreted by activated CD4+ T cells, NK cells, and dendritic cells. It drives T-cell proliferation, Th1 differentiation, and NK cell activity while also supporting regulatory T cell (Treg) function for immune tolerance. Signaling through the IL-2 receptor (IL-2Rαβγ) activates JAK-STAT pathways, promoting cell survival and expansion. Rat IL-2 shares ~70% homology with mouse IL-2 but differs significantly from humanIL-2, requiring species-specific detection methods (e.g., ELISA, flow cytometry). It is crucial in research on autoimmunity (e.g., EAE), transplantation, and cancer immunotherapy, with dysregulation linked to immune disorders. Recombinant IL-2 has therapeutic potential but demands rat-specific reagents for accurate study.
