Mechanisms promoting dendritic cell-mediated transmission of HIV

Mol Immunol. 2005 Feb;42(2):229-37. doi: 10.1016/j.molimm.2004.06.019.


Dendritic cells (DC) survey epithelial or mucosal surfaces for antigens, take them up via their endocytic or phagocytic receptors, process the captured antigens and migrate to the lymphatic tissues. In the draining lymph nodes they present the immunogenic peptides to T cells thereby inducing antigen-specific immune responses. HIV-1 in turn seems to have developed mechanisms to exploit the natural trafficking of DC to establish infection in its primary targets, the CD4+ T cells. This review discusses several aspects of DC-HIV interactions with a main focus on the attachment, internalisation and transmission of the virus by DC to cells, susceptible for infection with HIV.
