C-C趋化因子受体5型(CCR5)是HIV感染的关键参与者,因为它主要参与感染过程。对CCR5共受体作用的研究首先集中在其与病毒的结合以及导致HIV进入和传播的分子机制上。自然发生的CCR5突变的鉴定使科学家们能够将CCR5分子作为预防或限制体内HIV感染的有希望的靶标。在暴露但未感染的人群中,以及在长期控制感染的HIV血清阳性人群中,发现了自然产生的ccr5特异性抗体。这表明存在对CCR5共受体的天然自身免疫,并可能在HIV控制中发挥作用。这种天然免疫力促使了通过靶向CCR5实现抗hiv体液反应的策略,这将在这里描述。
The C-C chemokine receptor type 5 (CCR5) is a key player in HIV infection due to its major involvement in the infection process. Investigations into the role of the CCR5 coreceptor first focused on its binding to the virus and the molecular mechanisms leading to the entry and spread of HIV. The identification of naturally occurring CCR5 mutations has allowed scientists to address the CCR5 molecule as a promising target to prevent or limit HIV infection in vivo. Naturally occurring CCR5-specific antibodies have been found in exposed but uninfected people, and in a subset of HIV seropositive people who show long-term control of the infection. This suggests that natural autoimmunity to the CCR5 coreceptor exists and may play a role in HIV control. Such natural immunity has prompted strategies aimed at achieving anti-HIV humoral responses through CCR5 targeting, which will be described here.
