Interferon gamma is a pleiotropic cytokine which is now recognised as
an important modulator of the immune response. We now report the cloni
ng and sequencing of feline interferon gamma cDNA which was generated
by the polymerase chain reaction. At the nucleotide level feline ifn-g
amma shares 78% and 63% homology with human and murine cDNA equivalent
s. At the amino acid level the feline IFN-gamma shares 63% and 43% hom
ology with human and murine homologs respectively.
