A vacuolar type H(+)-ATPase regulates cytoplasmic pH in murine macrophages.

An Na(+)- and HCO3(-)-independent mechanism of cytoplasmic pH (pHi) recovery was previously demonstrated in acid-loaded macrophages (Swallow, C. J., Grinstein, S., and Rotstein, O. D. (1988) J. Biol. Chem. 263, 19558-19563). Acid extrusion was found to be ATP-dependent and sensitive to N-ethylmaleimide and N,N'-dicyclohexylcarbodiimide, suggesting involvement of an H(+)-pumping ATPase. In this ...

Acidocalcisomes in Toxoplasma gondii tachyzoites.

Toxoplasma gondii tachyzoites were loaded with the fluorescent indicator fura 2 to investigate the transport mechanisms involved in maintaining their intracellular Ca2+ homoeostasis. The mitochondrial ATPase inhibitor oligomycin and the endoplasmic-reticulum Ca(2+)-ATPase inhibitor thapsigargin increased the intracellular Ca2+ concentration ([Ca2+]i), thus indicating the requirement for ATP and...

Immunogenicity of Gamma-Irradiated Toxoplasma gondii Tachyzoites in Mice

The Immunogenicity of γ-irradiated tachyzoites of a highly virulent strain of Toxoplasma gondii (RH strain) was investigated. Immunized mice survived challenge infection and displayed increased interferon gamma (INF-γ ) production. On the other hand, nonimmunized controls died after 10 days and displayed a significantly decreased lymphoproliferative response to Concanavalin A (Con A). No tachyz...

Triazine Inhibits Toxoplasma gondii tachyzoites in vitro and in vivo.

The triazine WR99210 [4,6-diamino-1,2-dihydro-2,2-dimethyl-1-(2,4,5-trichlorophenoxypropyloxy)-1,3,5 triazine] inhibits Toxoplasma gondii in vitro at nanomolar levels (P < 0.05). The 50% inhibitory concentration (IC(50)) was approximately 50 nM. It is a potent inhibitor in vitro and is also effective in vivo. Administration of WR99210 parenterally (i.e., intraperitoneally) reduced the mean numb...

Toxoplasma gondii aspartic protease 1 is not essential in tachyzoites.

Aspartic proteases are important virulence factors for pathogens and are recognized as attractive drug targets. Seven aspartic proteases (ASPs) have been identified in Toxoplasma gondii genome. Bioinformatics and phylogenetic analyses regroup them into five monophyletic groups. Among them, TgASP1, a coccidian specific aspartic protease related to the food vacuole plasmepsins, is associated with...
