AB The ability of the human immunodeficiency virus (HIV) to persist and
replicate in human CD4+ T lymphocytes and mononuclear phagocytes is
under the control of both virally encoded proteins and a variety of
host-related factors. Ultraviolet (UV) light has been shown to induce
transcription and expression of HIV. Both DNA damage and repair and DNA
damage/repair-independent pathways caused by UV irradiation lead to
expression of proviral HIV genomes via activation of the cellular
transcription factor NF-kappa B. Transgenic mice that contain either
long terminal repeat (LTR)-reporter genes or HIV genomes, either full
length or deleted in the gag-pol region, express RNA and proteins at the
epidermal level, particularly after UV irradiation. Furthermore,
UV-triggered release of soluble factors capable of inducing expression
of HIV in non-irradiated cells has been observed. Among other host
factors, the functional network of pro-inflammatory and immunoregulatory
cytokines has been demonstrated to act as a potent regulator of HIV
replication, at least in different in vitro systems of infection.
