Numerous studies highlight the importance of macrophages for optimal host protection against systemic Candida albicans infections. We chose the murine macrophage cell line RAW 264.7 and the wild-type strain C. albicans SC5314 to study of the induced expression/repression of proteins in macrophages when they are in contact with C. albicans, based on 2-DE, comparison between different gels and protein identification. RAW 264.7 cells were allowed to interact with C. albicans cells for 45 min, and a significant differential protein expression was observed in these macrophages compared to controls. Gels were stained with SYPRO Ruby, allowing a better quantification of the intensity of the protein spots. Fifteen spots were up-regulated, whereas 32 were down-regulated; 60 spots appeared and 49 disappeared. Among them, we identified 11 proteins: annexin I, LyGDI (GDID4), Hspa5 (Grp78, Bip), tropomyosin 5 and L-plastin, that augment; and Eif3s5, Hsp60, Hspa9a, Grp58 (ER75), and Hspa8a (Hsc70), that decrease. The translation elongation factor (Eef2p) is modified in some of its different protein species. Many processes seem to be affected: cytoskeletal organisation, oxidative responses (superoxide and nitric oxide production) and protein biosynthesis and refolding.
