Macrophage restriction of Marek's disease virus replication and lymphoma cell proliferation.
Macrophages are shown to restrict the replication of Marek's disease virus (MDV) and isotope uptake by spleen cells from chickens bearing Marek's disease (MD) tumors. The titer of virus from duck embryo fibroblasts (DEF) co-cultivation with MDV-spleen cells pretreated to deplete marcophages was 4- to 18-fold higher than with untreated cells. Treated MDV-spleen cells increased isotope uptake by 2-fold. These restrictive activities are attributable to macrophage regulation of cell proliferation.
