Extract

The ultrastructural pathology of HIV infection is a broad subject, owing to the fact that the transmission electron microscope has played an integral part in our understanding of HIV disease. The subject can be divided into three basic areas: HIV pathogenesis, opportunistic infections (OI), and neoplastic disease. Once HIV was determined to be a retrovirus, TEM confirmed its membership in the Lentivirus family and showed that it has a conical nucleoid. TEM has played a key role in our understanding of: 1) the CNS as a target of HIV, 2) the macrophage as a “trojan horse” for HIV, 3) how lymphocytes and macrophages differ in their HIV expression, 4) attachment of virions to the processes of follicular dendritic cells via complement and Fc receptors, and 5) the formation of multinucleated giant cells.
