AB The retroviruses linked with human cancer fall into two distinct
categories. Human T-cell leukemia viruses (HTLV-I, HTLV-II) are
oncoviruses. HTLV-I infection accounts for the major burden of adult
T-cell lymphoma and leukemia in regions such as Japan, the Caribbean
basin and some West African states. HTLV-II is widely endemic in native
Americans and has also been found among African bushmen. It is not so
definitely linked with malignant disease as HTLV-I but may be implicated
in a variant form of hairy cell leukemia. The tax genes of HTLV-I and
HTLV-II play a role in cell transformation by transactivating cellular
genes. Human immunodeficiency viruses (HIV-1, HIV-2) are lentiviruses
and are the principal causes of AIDS. The cancers linked with HIV
infection are the same as those seen in immunodeficiency caused by
hereditary defects or by iatrogenic immunosuppression, in particular,
B-cell lymphoma and Kaposi's sarcoma. Epidemiological investigations of
Kaposi's sarcoma in AIDS patients indicate that it may be initiated by a
transmissible agent independent of HIV but will not normally be manifest
in immunocompetent individuals. In addition, studies of Kaposi cells in
culture and of some transgenic mice suggest that the HIV TAT protein may
promote Kaposi-like cell proliferation.
