IFN-γ is an acid-labile interferon produced by CD4 and CD8 T lymphocytes, as well as activated NK cells.? IFN-γ receptors are present in most immune cells, which respond to IFN-γ signaling by increasing the surface expression of class I MHC proteins.? This promotes the presentation of antigen to T-helper (CD4+) cells.? IFN-γ signaling in antigen-presenting, cells and antigen-recognizing B and T lymphocytes, regulates the antigen-specific phases of the immune response.? Additionally, IFN-γ stimulates a number of lymphoid cell functions, including the anti-microbial and anti-tumor responses of macrophages, NK cells, and neutrophils.? Human IFN-γ is species-specific and is biologically active only in human and primate cells.? Recombinant Murine IFN-γ is a 15.6 kDa protein containing 134 amino acid residues.
