- Abstract
To study the mechanism by which human host cells respond to an infection of <italic>Toxoplasma gondii</italic>, we monitored the level of poly(A)-binding protein (PABP), an indicator of translation. Here, we report an observation of the relocalization of PABPs in human host cells upon <italic>T</italic>. <italic>gondii</italic> infection. Notably, the aggregates of PABPs formed upon infection are mainly found in the nucleus, which is a different response from that found after exposure to heat shock. Pyrimethamine treatment of the infected monolayers inhibits the multiplicity of the parasite and reverses the relocalization of PABP aggregates. This active interaction between the infected mammalian host cells and <italic>T</italic>. <italic>gondii</italic> appears to be different from that caused by viral infection.
