Abstract

Most parasitic skin infections are averted by very efficient strategies of preventing pathogen invasion. Innate immune cells such as mast cells, macrophages and dendritic cells are responsible for detecting parasites and for recruiting proinflammatory cells that help to contain and control the pathogen at sites of infection. This induces efficient adaptive immunity, which is crucially important for parasite control. Using the example of cutaneous leishmaniasis, we highlight how the skin utilizes different strategies to prevent skin infection and how containment of the infection to the skin site may reduce the harm that otherwise may result for the entire organism.

摘要

大多数寄生性皮肤感染可通过非常有效的预防病原体入侵策略得以避免。诸如肥大细胞、巨噬细胞和树突状细胞等固有免疫细胞负责检测寄生虫,并招募促炎细胞,这些促炎细胞有助于在感染部位遏制和控制病原体。这会诱导有效的适应性免疫,而适应性免疫对于控制寄生虫至关重要。以皮肤利什曼病为例,我们强调皮肤如何利用不同策略预防皮肤感染,以及将感染控制在皮肤部位如何减少否则可能对整个机体造成的损害。
