环境中充满了几乎无数种真菌,我们的免疫系统必须进行调整以应对持续接触它们的情况。此外,越来越清楚的是,我们身体的许多表面都定殖有复杂的真菌群(真菌组),就像它们定殖有复杂的细菌群一样。免疫系统必须耐受共生真菌的定植,但要防御真菌入侵。只有当这种平衡被严重的免疫抑制或基因突变等破坏时,真正危及生命的真菌感染才会常见。最近的研究已经开始揭示这种平衡是如何建立和维持的,并建议未来研究真菌在稳态条件下的作用。
The environment is suffused with nearly countless types of fungi, and our immune systems must be tuned to cope with constant exposure to them. In addition, it is becoming increasingly clear that many surfaces of our bodies are colonized with complex populations of fungi (the mycobiome) in the same way that they are colonized with complex populations of bacteria. The immune system must tolerate colonization with commensal fungi but defend against fungal invasion. Truly life-threatening fungal infections are common only when this balance is disrupted through, for example, profound immunosuppression or genetic mutation. Recent studies have begun to shed light on how this balance is established and maintained, and suggest future studies on the role of fungi in homeostatic conditions.
