Abstract

125I-labeled recombinant gp120 bound to primary cultures of human fetal astrocytes with a single class of 260-kDa binding sites, with a K(d) of 26 nM and maximal number of binding sites of 29.9 fmol/4 x 104 cells. Neither CD4 nor galactocerebroside was detectable on astrocytes, and 125I-labeled recombinant gp120 binding to astrocytes was not blocked by antibodies against galactocerebroside or the gp120 binding domain of CD4.
