East Coast fever (ECF) is a highly fatal lymphoproliferative disease of cattle caused by Theileria parva, a tick-borne intracellular apicomplexan parasite. Parasite antigens that are targets of protective cytotoxic T lymphocyte (CTL) responses are required to formulate a sub-unit vaccine against ...
Immunity against the bovine intracellular protozoan parasite Theileria parva has been shown to be mediated through the destruction of parasite infected lymphocytes by MHC class I restricted CD8+ CTL. Six parasite proteins targeted by CTL from T. parva immune cattle have been identified and raised...
Theileria parva antigens recognized by cytotoxic T lymphocytes (CTLs) are prime vaccine candidates against East Coast Fever in cattle. A strategy for enhancing induction of parasite-specific T cell responses by increasing recruitment and activation of dendritic cells (DCs) at the immunization sit...
N-Ribohydrolases, including the inosine-adenosine-guanosine-preferring (IAG) nucleoside hydrolase, have been proposed to be involved in the nucleoside salvage pathway of protozoan parasites and may consitute rational therapeutic targets for the treatment of these diseases. Reported is the complet...
Recent studies suggest that peptidyl-prolyl isomerases of the cyclophilin family, that access the secretory pathway, can be involved in the interaction of parasitic protozoa with mammalian host cells. The amino acid sequence of a cDNA encoding a cyclophilin family member of the intracellular pro...
The purine salvage pathway of parasitic protozoa is currently considered as a target for drug development because these organisms cannot synthesize purines de novo. Insight into the structure and mechanism of the involved enzymes can aid in the development of potent inhibitors, leading to new cur...
Cyclophilin A from the bovine parasite Trypanosoma brucei brucei has been cloned, expressed in Escherichia coli, purified and crystallized in the presence of cyclosporin A using ammonium sulfate as a precipitant. The crystals belong to the orthorhombic crystal system with unit-cell dimensions of ...
