[sci.med.aids] CD-4

I have wondered where the name "CD4" comes from, but I've never remember to
ask someone who knows.

I was reading the description of a drug called "Orthoclone" last night.
Orthoclone is an immunosuppressant and is used to help prevent graft
rejection by blocking the function of CD3 in T cells.

The description included this sentence: "The CD3 designation identifies the
specificity of the antibody as the Cell Differentiation (CD) cluster 3
defined by the First International Workshop on Human Leukocyte
Differentiation Antigens."

So now I know.
