Characterization of the Fine Specificity of Bovine CD8 T-Cell Responses to Defined Antigens from the Protozoan ParasiteTheileria parva [PDF]
ABSTRACTImmunity against the bovine intracellular protozoan parasiteTheileria parvahas been shown to be mediated by CD8 T cells. Six antigens targeted by CD8 T cells fromT. parva-immune cattle of different major histocompatibility complex (MHC) genotypes have been identified, raising the prospect of developing a subunit vaccine.

Inhibitory effects on protein kinase C activity by lipophosphoglycan fragments and glycosylphosphatidylinositol antigens of the protozoan parasite Leishmania [PDF]
Fragments of the lipophosphoglycan of Leishmania donovani were generated by phospholipase C digestion and mild acid hydrolysis. The fragments were purified and examined for inhibitory activity on protein kinase C isolated from rat brains. On a molar basis, the 1-O-alkylglycerol portion of LPG exhibited the most inhibitory activity, whereas the ...

Evolution and diversity of secretome genes in the apicomplexan parasite Theileria annulata [PDF]
<b>BACKGROUND</b>: Little is known about how apicomplexan parasites have evolved to infect different host species and cell types. Theileria annulata and Theileria parva invade and transform bovine leukocytes but each species favours a ...

Eimeria tenella protein trafficking: differential regulation of secretion versus surface tethering during the life cycle [PDF]
Eimeria spp. are intracellular parasites that have a major impact on poultry. Effective live vaccines are available and the development of reverse genetic technologies has raised the prospect of using Eimeria spp.

The genome of the protozoan parasite Cystoisospora suis and a reverse vaccinology approach to identify vaccine candidates [PDF]
Vaccine development targeting protozoan parasites remains challenging, partly due to the complex interactions between these eukaryotes and the host immune system.

Evidence for conservation in antigen gene sequences combined with extensive polymorphism at VNTR loci [PDF]
Theileria parva is a tick‐transmitted apicomplexan protozoan parasite that infects lymphocytes of cattle and African Cape buffalo (Syncerus caffer), causing a frequently fatal disease of cattle in eastern, central and southern Africa.

A perspective on clonal phenotypic (antigenic) variation in protozoan parasites
Intra-clonal phenotypic (antigenic) variation is used by many pathogens to evade the consequences of immune-mediated killing by mammalian hosts. In this substantially theoretical article, I emphasise that antigenic variation (sensu stricto) involves no change in genotype; its importance as a mechanism for promoting pathogen transmission and its ...
