皮肤粘膜利什曼病是由维亚利什曼亚属的细胞内寄生虫感染引起的,包括古yanleishmania。病理发展后,寄生虫传播到鼻咽组织,在那里破坏性的转移性病变形成慢性炎症。目前,涉及病变发展的机制尚不清楚。本研究表明,转移性寄生虫具有高利什曼RNA病毒- 1 (LRV1)负荷,该负荷可被宿主toll样受体3 (TLR3)识别,从而诱导促炎细胞因子和趋化因子。矛盾的是,这些tlr3介导的免疫反应使小鼠更容易受到感染,并且动物出现了增加的足垫肿胀和寄生虫病。因此,转移性寄生虫中的LRV1破坏了宿主对利什曼原虫的免疫反应,并促进了寄生虫的持久性。
Mucocutaneous leishmaniasis is caused by infections with intracellular parasites of the Leishmania Viannia subgenus, including Leishmania guyanensis. The pathology develops after parasite dissemination to nasopharyngeal tissues, where destructive metastatic lesions form with chronic inflammation. Currently, the mechanisms involved in lesion development are poorly understood. Here we show that metastasizing parasites have a high Leishmania RNA virus–1 (LRV1) burden that is recognized by the host Toll-like receptor 3 (TLR3) to induce proinflammatory cytokines and chemokines. Paradoxically, these TLR3-mediated immune responses rendered mice more susceptible to infection, and the animals developed an increased footpad swelling and parasitemia. Thus, LRV1 in the metastasizing parasites subverted the host immune response to Leishmania and promoted parasite persistence.
