HIV-1 subtype CRF01_AE and B differ in utilization of low levels of CCR5, Maraviroc susceptibility and potential N-glycosylation sites

HIV subtypes not only predominate in different geographical regions but also differ in key phenotypic characteristics. To determine if genotypic and/or phenotypic differences in the Envelope (Env) glycoprotein can explain subtype related differences, we cloned 37 full length Envs from Subtype B and AE HIV infected individuals from Singapore. Our data demonstrates that CRF01_AE Envs have lower Potential N Glycosylation Sites and higher risk of ×4 development. Phenotypically, CRF01_AE were less infectious than subtype B Envs in cells expressing low levels of CCR5.
