We reassessed the infection ability of human primary preadipocytes. The use of X4, R5 or VSV-G-pseudotyped viral particles indicated that viral entry is the limiting step. However, transfection with HIV-1 receptors restored efficient infection. Analyses of CD4, CXCR4 and CCR5 expression on preadipocytes and adipocytes revealed that receptor co-expression levels did not permit HIV-1 entry into adipose cells from all biopsies tested. We concluded that adipose tissue cannot be infected with HIV-1 in vivo.
