AB A possible mechanism for explanation of the simultaneous development of
acquired immunodeficiency syndrome (AIDS) and malignant tumors may be
based on the cell-fusion process with the participation of
immunocompetent cells. If the fusion proceeds with a high intensity,
i.e. a great number of cells (including immunocompetent cells) are
involved in the process, it will cause a rise in multinuclear
formations-polykaryocytes. Since polykaryocytes are incapable of
proliferation, their formation is equivalent to elimination of
immunocompetent cells and may lead to immunodeficiency. If the intensity
of fusion is low, the occurrence of binuclear formations-
dikaryons-seems more frequent. We have shown (1) a possibility of the
transformation of dikaryons into tumor cells under certain conditions
and since immunocompetent cells are dominant by their phenotypic
properties the malignant cells in AIDS should have mainly macrophage,
lymphoid or intermediate morphology. Even low doses of various chemical
carcinogens may cause malignancy by the formation of special defects in
plasma membrane which promote cell fusion, whereas under high doses of
carcinogens (or high intensity of their action) the formation of
polykaryocytes and the development of immunodeficiency seem more
probable, though it does not exclude the possibility of cancer
development.
