DescriptionIFN-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 Human IFN-γ is a 16.8 kDa protein containing 144 amino acid residues.
