    Linkage of Amino Acid Variation and Evolution of Human Immunodeficiency Virus Type 1 gp120 Envelope Glycoprotein (Subtype B) with Usage of the Second Receptor

    To clarify the relationship between the amino acid variations of the gp120 of human immunodeficiency virus type 1 (HIV-1) and the chemokine receptors that are used as the second receptor for HIV, we evaluated ...
