Abstract: | Heat-shock proteins (HSPs) are evolutionarily highly conserved polypeptides synthesized by cells to preserve cellular functions under a variety of stressful conditions, including infections. In infections, both host cells and pathogens express HSPs, although the role of these molecules in the host-pathogen relationship is elusive. Here, Hajime Hisaeda and Kunisuke Himeno show that a correlation exists between the 65 kDa HSP molecule (HSP65) and protection against Toxoplasma gondii infection, suggesting that this protein contributes to the host defense system. These findings may help in the understanding of the complicated host-parasite relationship. |
