tokens: In this study , we investigated the ability of the major envelope glycoprotein of HIV , glycoprotein 120 ( gp120 ) , to regulate intercellular adhesion molecule-1 ( ICAM-1 ) expression in glial cells , because ICAM-1 is important in mediating immune responsiveness in the CNS , facilitating entry of HIV -infected cells into the CNS , and promoting syncytia formation .
