Interaction of C. glabrata wild type and C. albicans yeast-locked efg1ฮฮ/cph1ฮฮ mutant cells with macrophages.
Should I stay or should I go? Research in #mBio suggests the fungus Candida glabrata may actively prolong the part of its life spent inside macrophages, which could contribute to immune evasion, antifungal resistance and potential recurrence of infection. asm.social/2Q2
