VIROLOGY Infectious Synapse

Dendritic cells (DCs) may play a role in host-pathogen interactions. For example, certain proteins expressed on DCs, such as DC-SIGN, can stimulate the efficiency of infection of target cells by the human immunodeficiency virus (HIV). McDonald et al. visualized individual particles of HIV in living cells and found that DC-associated HIV was recruited to the site of contact with target cells such as T cells. Simultaneously, the HIV receptor and coreceptor were recruited to the contact site. This recruitment effectively concentrates HIV, its receptor, and its coreceptor and presumably facilitates infection.
