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. [...]

Myeloid cells are key players in the recognition and response of the host against invading viruses. Paradoxically, upon HIV-1 infection, myeloid cells might also promote viral pathogenesis through trans-infection, a mechanism that promotes HIV-1 transmission to target cells via viral capture and storage.

Background: Cell-to-cell HIV transmission requires cellular contacts that may be in part mediated by the integrin leukocyte function antigen (LFA)-1 and its ligands intercellular adhesion molecule (ICAM)-1, -2 and -3. [...]

9 p, 5.6 MB HIV and mature dendritic cells : Trojan exosomes riding the Trojan horse? / Izquierdo Useros, Nuria (IrsiCaixa Foundation) ; Naranjo Gómez, María del Mar (Fundació Institut per a la Investigació en Ciències de la Salut Germans Trias i Pujol) ; Erkizia, Itziar (IrsiCaixa Foundation) ; Puertas, María Carmen (IrsiCaixa Foundation) ; Borràs Serres, Francesc Enric (Fundació Institut per a la Investigació en Ciències de la Salut Germans Trias i Pujol) ; Blanco, Julià (IrsiCaixa Foundation) ; Martínez Picado, Francisco Javier (Institució Catalana de Recerca i Estudis Avançats)
Exosomes are secreted cellular vesicles that can induce specific CD4+ T cell responses in vivo when they interact with competent antigen-presenting cells like mature dendritic cells (mDCs). The Trojan exosome hypothesis proposes that retroviruses can take advantage of the cell-encoded intercellular vesicle traffic and exosome exchange pathway, moving between cells in the absence of fusion events in search of adequate target cells.

200 p, 4.9 MB HIV-1 immune activation induces Siglec-1 expression and enhances viral transmission in myeloid cells / Pino Claveria, Maria ; Jaraquemada, Dolores, dir.

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. [...]
Dendritic cells (DCs) are specialized antigen-presenting cells. However, DCs exposed to human immunodeficiency virus (HIV) are also able to transmit a vigorous cytopathic infection to CD4+ T lymphocytes, a process that has been frequently related to the ability of DC-SIGN (Dendritic Cell-Specific Intercellular adhesion molecule-3-Grabbing Non-integrin) to bind HIV-1 envelope glycoproteins.
