Hovanessian. Portrait of Professor Ara Hovanessian in 1994, French AIDS researcher at the Pasteur Institute in Paris. A culture of cells infected with the AIDS virus is seen in the foreground. Hovanessian is involved with research on the CD26 receptor found on T-cells of the human immune system. The AIDS virus attacks T-cells, targetting these cells by recognising CD4 receptors on the cell membrane. However, it is thought that another receptor known as CD26 enables the AIDS virus to infect the T-cell. Hovanessian is developing drugs to block this interaction of virus with CD26 receptor, so preventing AIDS viral infection. His drugs are already effective on cultured cells.
