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. -- Because of mail/disk problems at Netcom, I have adopted the policy of responding in some way to all non-listserv/non-acknowledgement email. If you don't hear from me, I didn't get it. Jack Hamilton jfh@netcom.uucp or claris!netcom!jfh
