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.
本初步研究旨在评估来自 88 名 HIV 阳性患者、5 名暴露后阴性(ESN)和 5 名血清阴性志愿者的腮腺唾液中抗-MPER-分泌型 IgA(SIgA)的中和活性。48.9%的 HIV 阳性患者和 100%的 ESN 患者显示抗 gp41 SIgA。25.6%的 HIV 阳性患者和 100%的 ESN 患者的抗-MPER SIgA 能够有效中和 HIV-1 原发分离株 SF162(IC 50)。ESN 中的中和活性保持在比 HIV 阳性分泌物更低的浓度。
