In this study we examined secretory IgA, isolated from the parotid saliva of 10 HIV-1-infected subjects, for its ability to influence HIV-1 infection of peripheral blood mononuclear cells with two R5 and two X4 primary isolates. Salivary IgA from four subjects was found to inhibit both R5 viruses but not the X4 viruses. In another subject, salivary IgA inhibited both X4 viruses but not the R5 viruses. The specificity of these antibodies seemed to be directed against, but not restricted to, gp160 and gp120. Compared with subjects whose salivary IgA did not inhibit HIV-1 infection, subjects who displayed neutralizing activity were in relatively early stages of disease and had CD4+T cell counts greater than 200 cells/μl. Our data indicate the presence of tropism-specific (more frequently R5-specific) neutralizing antibodies in HIV-1-infected subjects. Because mucosal transmission of HIV-1 occurs exclusively in R5 viruses, and X4 viruses often emerge in established infection and account for viral persistence later in disease, our data suggest a potential role for secretory IgA in preventing viral transmission, but a less likely effect on chronic infection.
