Mucosal dendritic cells in HIV-1 susceptibility: a critical role for C-type lectin receptors
2017
Sexual transmission is the major route of HIV-1 infection worldwide. The interaction of HIV-1 with mucosal dendritic cells (DCs) might determine HIV-1 susceptibility as well as initial antiviral immunity controlling virus in the chronic phase. Different DC subsets reside in mucosal tissues and express specific C-type lectin receptors (CLRs) that interact with HIV-1 with different outcomes. HIV-1 has been shown to subvert CLRs for viral transmission and immune evasion, whereas CLRs can also protect against HIV-1 infection. Here, we will discuss the role of CLRs in HIV-1 transmission and adaptive immunity, and how the CLRs dictate the function of DCs in infection. Ultimately, understanding the interplay between CLRs and HIV-1 will lead to targeted approaches in the search for preventative measures.
