“…61,62 The buffering capacity of semen may help to maintain conditions that are conducive to HIV-1 stability and infection. [63][64][65][66] 72 Furthermore, complement activation in seminal fluid generates C3 cleavage and augments HIV-1 infection in epithelial cells. 73 In vaginal epithelial cells, SP induces the secretion of CCL20 and subsequent recruitment of LCs.…”

“…Informed consent was obtained from each patient before sperm collection. Ejaculates were obtained by masturbation under hygienic conditions, after a period of 2-4 d of sexual abstinence, and were collected in sterile containers as previously described (27). The samples were allowed to liquefy for 30 min at 37˚C.…”

“…Existe evidencia molecular que sujetos infectados por HIV pueden eyacular pequeñas cantidades espermatozoides anormales HIV-1 DNA-positivos, sin embargo, espermatozoides HIV-1 DNApositivos que lleven una amplia variedad de alteraciones estructurales puede ser incapaz de fertilizar y/o generar embriones viables (Muciaccia et al, 2007). Es así, que los espermatozoides actúan concertadamente con células dendríticas (CDs) pudiendo afectar el curso temprano de la transmisión sexual de la infección por HIV-1, además de transmitirse de manera eficiente a macrófagos y células T (Ceballos et al, 2009). Finalmente, teniendo en consideración que el semen es la principal vía de transmisión del HIV-1, es poco lo que se conoce acerca de sus efectos sobre la inefectividad viral (Munch et al, 2007).…”
