Human CD300a is known to promote the infection by Dengue and other enveloped viruses and is overexpressed on CD4+ T cells from HIV-1 infected patients. We found that infected CD4+RA- T cells from untreated HIV-1 infected patients were mostly CD300a+. Furthermore, CD300a expressing CD4+RA- T cells from healthy donors were significantly more infected by HIV-1 in vitro than CD300a- cells. CD300a might represent a biomarker of susceptibility to HIV-1 infection on memory CD4+ T lymphocytes.
