MACROPHAGES AS A CELLULAR EXPRESSION OF INHERITED NATURAL RESISTANCE

Abstract
Tissue cultures of peritoneal macrophages prepared from individual mice of the eighth generation of backcrossing between virus-resistant hybrids and virus-susceptible C3H mice were exposed to West Nile virus. Half of the cultures failed to support virus multiplication, while the remaining cultures yielded infectious virus. This distribution of resistance and susceptibility in macrophage culture reflected, on the cellular level, genes segregating for virus resistance and susceptibility on the whole animal level.
