Bovine cytotoxic T cell clones which recognize lymphoblasts infected with two antigenically different stocks of the protozoan parasite Theileria parva

European Journal of Immunology, 1987
AbstractThe Muguga and Marikebuni stocks of Theileria parva differ on the basis of cross‐protection and in their schizont antigen profile determined with a panel of parasitespecific monoclonal antibodies. The phenotype and specificity of six cytotoxic T cell clones generated from an animal immunized against T. parva (Marikebuni) were investigated.

A mouse protozoan boosts antigen-specific mucosal IgA responses in a specific lipid metabolism- and signaling-dependent manner

Nature Communications
IgA antibodies play an important role in mucosal immunity. However, there is still no effective way to consistently boost mucosal IgA responses, and the factors influencing these responses are not fully understood. We observed that colonization with the murine intestinal symbiotic protozoan Tritrichomonas musculis (T.mu) boosted antigen-specific ...

Ontological representation, modeling, and analysis of parasite vaccines

Journal of Biomedical Semantics
Background Pathogenic parasites are responsible for multiple diseases, such as malaria and Chagas disease, in humans and livestock. Traditionally, pathogenic parasites have been largely an evasive topic for vaccine design, with most successful vaccines ...

Immunomodulation of Patients with Canine Visceral Leishmaniasis at Different Stages: A 12-Month Follow-Up Study Using LaSap

Vaccines
Background/Objectives: Canine visceral leishmaniasis (CVL) is one of the main neglected protozoan diseases in the world. Dogs play a fundamental role in the maintenance of Leishmania infantum in the Americas, and we have already encountered resistance ...
