23. Human Immunodeficiency Virus (HIV)
Terese Winslow applies her artistic eye to the creation
of accurate, clear scientific illustrations. "HIV" was created
for the cover of the prestigious journal Science.
HIV infects T-lymphocytes in the blood stream, ultimately
causing AIDS. Terese Winslow created this artwork to give
scientists new insight into how HIV infects T-lymphocytes.
The virion is shown in the first stage of infection, when the
virion attaches to the surface of the T-cell. The molecules
involved in this docking process are of particular interest to
scientists, so she rendered them accurately according to the
most up-to-date scientific information. These molecules
include gp120 (the blue 'mushrooms' on the surface of the
virus), CD4 (the long red molecules on the cell surface),
and chemokine receptors (the groups of blue cylinders on
the cell surface). The artwork was created with Adobe
Photoshop and Fractal Painter on a Power Macintosh.
