Title: Characteristics of immune interferon produced by human lymphocyte cultures compared to other human interferons. Author: Valle MJ, Jordan GW, Haahr S, Merigan TC. Journal: J Immunol; 1975 Jul; 115(1):230-3. PubMed ID: 239056. Abstract: A factor with antiviral activity has been produced in vitro by combined macrophage-lymphocyte cultures from patients with recent herpes labialis in response to HSV antigen stimulation. It has been designated "immune interferon" and characterized in comparison to several other human interferons. It was shown to be relatively unstable at pH 2 and at 56 degrees C. Rabbit anti-human leukocyte interferon serum was shown to be less active against immune interferon than against diploid cell interferon or against vesicle fluid interferon. The possibility of immune interferon being a totally different anti-viral protein or a protein with certain shared antigen determinants or structures with classical viral interferon is discussed. A simplified method for the assay of anti-interferon sera with microtiter plates is also described.[Abstract] [Full Text] [Related] [New Search]
