Abstract
Reproductive efficiency of herpes simplex virus type 1 has been determined in several normal and mutant human skin fibroblast lines. The mutant cell lines were derived from individuals diagnosed as having Duchenne muscular dystrophy, a disease thought to involve genetically determined membrane defects. Yields of infectious virus, determined by plaque assay on rabbit kidney cell monolayers, were consistently lower from dystrophic cells than from normal cells. The yield from dystrophic lines was 3–20% of the normal. The time course of production of infectious particles did not appear to vary between dystrophic and normal host cells. Also, the initiation of replication of the viral genome did not appear to be altered in the dystrophic lines. It is proposed that a late maturation function is involved in the lower virus productivity in dystrophic cells.
