A Candida glabrata calcineurin mutant exhibited increased susceptibility to both azole antifungal and cell wall-damaging agents and was also attenuated in virulence. Although a mutant lacking the downstream transcription factor Crz1 displayed a cell wall-associated phenotype intermediate to that of the calcineurin mutant and was modestly attenuated in virulence, it did not show increased azole susceptibility. These results suggest that calcineurin regulates both Crz1-dependent and -independent pathways depending on the type of stress.
光滑念珠菌钙调神经磷酸酶突变体对唑类抗真菌药物和细胞壁破坏剂的敏感性均增加,其毒力也减弱。虽然缺乏下游转录因子 Crz1 的突变体表现出与钙调神经磷酸酶突变体相关的细胞壁表型,但毒力中度减弱,对唑类药物的敏感性并未增加。这些结果表明,钙调神经磷酸酶根据应激的类型调节依赖于 Crz1 的和不依赖于 Crz1 的途径。
