Natural resistance to African trypanosomiasis in certain Bos taurus cattle in West Africa, called trypanotolerance, may hold solutions for control of this economically crippling disease. Comparison of immune responses between trypanotolerant and trypanosusceptible cattle have shown some differen...

The membrane-associated form of the variable surface glycoprotein (mfVSG) from African trypanosomes is a potent macrophage activator capable of inducing production of tumor necrosis factor z (TNFalfa) in both bovine and murine models. Using a bovine model. we have re-investigated the hypothesis t...

Bovine bone marrow-derived macrophages were infected in vitro with non-cytopathic or cytopathic strains of bovine viral diarrhoea virus. Infection with both biotypes resulted in a decreased production of tumour necrosis factor alpha upon stimulation with heat-inactivated Salmonella dublin or lipo...

Experimental infections of mice with the African trypanosome Trypanosoma brucei lead to a profound state of T-cell unresponsiveness in the lymph node cell (LNC) compartment. This suppression is mediated by macrophage-like cells which inhibit interleukin 2 (IL-2) secretion and down-regulate IL-2 r...
