Pathogen interactions with the host immune response components are critical for establishing protective immunity and pathological responses against Leishmania parasites. A predominant proinflammatory profile associated with enhanced phagocytosis trigger a cell-mediated immune response that is relevant to infection control. On the other hand, an anti-inflammatory phenotype, correlated with a predominant modulated/regulatory response, favors intracellular proliferation of Leishmania parasites and disease progression. In this context, chemokines play an important role in determining cellular composition at inflammatory sites. Leishmania infection induces the expression of various chemokines and chemokine receptors in the mammalian host, which can subvert the host immune responses. Indeed, the balance and dynamic changes in cytokines and chemokines may control or predict the disease outcome. In this review, we address our current knowledge regarding the chemokines and chemokines receptors' role in the immunopathogenesis of Tegumentary and Visceral Leishmaniasis.
病原体与宿主免疫反应成分的相互作用对于建立针对利什曼原虫寄生虫的保护性免疫和病理反应至关重要。与增强吞噬作用相关的主要促炎特征触发细胞介导的免疫反应,与感染控制相关。另一方面,与主要调节/调节反应相关的抗炎表型有利于利什曼原虫寄生虫的细胞内增殖和疾病进展。在这种情况下,趋化因子在确定炎症部位的细胞组成方面起着重要作用。利什曼原虫感染会诱导哺乳动物宿主中各种趋化因子和趋化因子受体的表达,从而改变宿主的免疫反应。事实上,细胞因子和趋化因子的平衡和动态变化可能会控制或预测疾病的结果。在这篇综述中,我们将讨论我们目前对趋化因子和趋化因子受体在皮肤和内脏利什曼病免疫发病机制中的作用的了解。
