Recombinant bovine IFN gamma is a potent inhibitor of Cowdria ruminantium growth in vitro irrespective of the rickettsial stock, or the origin of the endothelial cells. These results suggest an important role for IFN gamma in protective immune responses against C. ruminantium infections. Here we ...

Dendritic cells (DC) constitute the most effective immune cell population for priming and recalling T cell responses to foreign antigens. DC patrol the peripheral tissues collecting foreign antigen for subsequent presentation by classical class II MHC molecules to T cells in the draining lymph no...

We describe a highly sensitive, non-radioactive assay for T cell activation, based on the rapid induction of class II MHC expression by constitutively negative bovine endothelial cells, when cultured in the presence of supernatants derived from activated bovine T cells. We demonstrate the effecti...

We describe the characterization of two subsets of bovine gamma delta T cells having distinct cell surface phenotype and tissue distribution. One population expresses the previously described 215000 MW WC1 antigen and is negative for the cell-surface differentiation antigens CD2. CD4, and CD8. Th...

The studies reported here describe methodology permiting the direct identification of antigens recognized by cytotoxic T lymphocytes. We demonstrated that bovine alloreactive CTL can detect a bovine MHC molecule transiently expressed in a COS cell population in a standard microcytotoxicity assay....
