Siglec-1/CD169 is a myeloid-cell surface receptor critical for HIV-1 capture and infection of bystander target cells. To dissect the role of SIGLEC1 in natura, we scan a large population genetic database and identify a loss-of-function variant (Glu88Ter) that is found in ∼1% of healthy people. [...]

Les cèl·lules mieloides són actors clau en el reconeixement i resposta de l'hoste contra els virus invasors. Paradoxalment, després de la infecció del VIH-1, les cèl·lules mieloides també poden promoure la patogènesis viral a través de la trans-infecció, un mecanisme que promou la transmissió del VIH-1 a les cèl·lules diana a través de la captura i emmagatzematge del virus.

Las células dendríticas (DCs) están especializadas en la presentación de antígeno. Sin embargo, las DCs expuestas al virus de la inmunodeficiencia humana (VIH) también son capaces de transmitir una potente infección citopática a los linfocitos T CD4+, un proceso que frecuentemente se ha relacionado con la capacidad que tiene el receptor DC-SIGN (Dendritic Cell-Specific Intercellular adhesion molecule-3-Grabbing Non-integrin) para unirse de forma específica a la glicoproteína de la envuelta viral.
