Abstract The recruitment of monocytes into the scrapie-affected brain was investigated in female mice reconstituted with male bone marrow, using a Y-chromosome-specific probe and F4/80 immunocytochemistry. Recruitment of monocytes could be demonstrated in six out of eight animals and the number of recruited cells correlated with the severity of vacuolation in most, but not all, animals. The proportion of microglia derived from recruited monocytes varied between individual animals, did not correlate with the increase in cellularity (glia) in affected areas of brain and did not affect the length of incubation period. Thus, it is unlikely that the recruitment of monocytes is a pivotal event in the development of early pathological changes in scrapie. The morphology of recruited cells in scrapie lesions, as revealed by F4/80 immunoreactivity, was indistinguishable from that of activated resident microglia.
