The novel dendritic cell receptor Siglec-1 binds sialyllactose moieties on HIV-1 membrane gangliosides, thereby enhancing HIV-1 transinfection. Dendritic cells (DCs) are essential antigen-presenting cells for the induction of immunity against pathogens. [...]

Dendritic cells (DCs) are essential in order to combat invading viruses and trigger antiviral responses. Paradoxically, in the case of HIV-1, DCs might contribute to viral pathogenesis through trans -infection, a mechanism that promotes viral capture and transmission to target cells, especially after DC maturation.
