Enhanced interferon response of leukocytes from immune animals. J. Bacteriol. 91:2185-2191. 1966.-The production of interferon was studied under in vitro conditions in peritoneal leukocytes or macrophages from mice immunized with Chikungunya virus (CV). Cultures of leukocytes obtained from animals immune to CV produced 2- to 10-fold greater amounts of interferon when exposed to an inoculum of CV than similar cell preparations from nonimmune, control animals. The viral inhibitor produced in increased quantity by CV-immune leukocytes had the biological - biochemical properties of interferon. The enhanced interferon production was inhibited by actinomycin D. This response of immune leukocytes was specific, - was initiated only by CV; it was not observed in leukocytes from animals immunized against other viruses which were challenged with CV. The presence of neutralizing antibody could not be related to this response. The observed increase in interferon production was not dependent upon an enhanced virus uptake. The data are presented as a possible new dimension of the immune response" - may suggest a mechanism for the phenomenon of "tissue immunity.""
