Abstract
A study to investigate the participation of T cells in macrophage-mediated responses during malaria was performed in nude (nu/nu) and littermate (nu/+) mice infected with Plasmodium berghei (PB). We found that in both groups of mice spleen cells suppressed the mitogenic response to LPS. Both nu/+ and nu/nu infected mice also showed liver macrophage activation, reflected by increased plasminogen activator release. These findings suggest that at least some of the macrophage changes during malaria infection are T-independent.
