Depression of mitogen response in spleen cells from reticuloendotheliosis virus-infected chickens and their suppressive effect on normal lymphocyte response.
Spleen cells and peripheral blood lymphocytes from chickens infected with reticuloendotheliosis virus (REV) were depressed in their responsiveness to phytohemagglutinin (PHA). When spleen cells from uninfected chickens were co-cultured with spleen cells from chickens infected with REV at 2 weeks of age, the PHA response by the normal cells was completely suppressed. Although spleen cells from chickens infected with REV at 6 or 9 weeks of age were also suppressed in their ability to respond to PHA, they did not suppress the mitogenic response of normal cells in mixed cultures.
