Characterization of liver lymphomyeloid cells in mice infected with Plasmodium yoelii sporozoites.
We have isolated, characterized and quantified the immunocompetent cells present in the extravascular hepatic compartment at various stages after Plasmodium yoelii malaria infection with sporozoites. Cytological analyses revealed a predominantly lymphoid population. In mice with a primary infection, the predominant cells were CD4+, CD8+ and B lymphocytes. In fully protected mice, CD3+ CD4- CD8- and polymorphonuclear cells, particularly eosinophils, were most common. The significance of changes in subpopulations is discussed in relation to antigen presentation and host-protective mechanisms.
