Composite image comparing the development of three types of retrovirus. Rows 1 & 2 show Human T-cell Lymphotropic Virus types 1 & 2 (HTLV-1 & HTLV-2) respectively. HTLV-1 & HTLV-2 cause leukaemia-type infections. The bottom row shows the development of the virus that leads to AIDS. It was originally believed to be related to HTLV-1 & -2 and was therfore designated HTLV-3 by the American team led by R. Gallo. In fact the bottom 3 images are of the AIDS virus isolated by the French team led by Luc Montagnier, who designated the virus LAV (Lymphodenopathy-Associated Virus). It has since been renamed HIV (Human Immunodeficiency Virus).
