Purpose of review: The aim of this review is to summarize the recent studies regarding the relationship between anti-DFS70 antibodies and HIV-1 infection. Examining the interaction between HIV-1 integrate (HIV-IN) and DFS70 and its role in the integration into the host's chromatin. Then, summarizing the importance of anti-DFS70 autoantibodies binding the DFS70 in the same region as the HIV-IN.
Recent findings: The interaction between HIV-IN and DFS70 protein could be a proficient target in the treatment against HIV-1 infection. The blockade of DFS70 is more effective than the blockade of HIV-IN as anti-HIV-1 drug. The anti-DFS70 autoantibodies could be an interesting therapeutic target for anti-HIV-1 treatment. Currently, there are no studies that measured the levels of anti-DFS70 autoantibodies in HIV-1-infected individuals.
Summary: The anti-DFS70 antibodies bind to the DFS70 autoantigen in the same region as the HIV-IN. This fact makes the autoantibodies a potential treatment for HIV-1-infected individuals. Blood levels of anti-DFS70 antibodies have not been measured in HIV-1-infected individuals. This issue opens new lines of research about the protective role of antibodies against HIV-1 infection.
