This preliminary study was performed to assess the neutralization activity of anti-MPER-secretory IgA (SIgA) from parotid saliva in 88 HIV+ patients, in five exposed seronegative (ESN) and in five seronegative volunteers. 48.9% of the HIV+ patients and 100% of ESN patients showed antigp41 SIgA. 25.6% of anti-MPER SIgA from HIV+ patients and 100% from ESN patients neutralized efficiently HIV-1 primary isolate SF162 (IC 50). The neutralization activity is maintained for much lower concentrations in ESN than in HIV+ secretions.
