Recombinant Chicken IL-9 (N-His)
Chicken interleukin-9 (Gallus gallus Interleukin-9, Chicken IL-9) is a secreted pleiotropic cytokine belonging to the IL-7/IL-9 family. Unlike mammalian IL-9, chicken IL-9 was cloned and functionally characterized relatively late: a 2022 study first cloned chicken IL-9 and found that its amino acid identity with mammalian IL-9 is less than 30%. Chicken IL-9 mRNA is abundantly detected only in the testis and thymus, and is significantly upregulated in mitogen-stimulated peripheral blood mononuclear cells (PBMCs); native chicken IL-9 is expressed as a glycosylated protein in activated PBMCs with a molecular weight of approximately 25 kD. Functionally, recombinant chicken IL-9 activates monocytes/macrophages to produce inflammatory cytokines and promotes CD3+ T cell proliferation, suggesting conserved pro-inflammatory and pro-proliferative activities in avian immune regulation.
