Immunologic effects of HIV in the lung.
This article covers a selected group of topics dealing with the contribution of lung immunocompetent cells in the host defense mechanisms against HIV. These include recent findings suggesting that bidirectional signals between alveolar macrophages and pulmonary cytotoxic T lymphocytes define regulatory networks, which contribute to the accumulation of HIV-specific effector cells in the lung microenvironment. The authors also emphasize the cell pattern of HIV infection in the lung, highlighting the role of the retrovirus in weakening pulmonary host defenses and its spreading into the lower respiratory tract.
