Predominance of CCR5-dependent HIV-1 subtype E isolates in Cambodia

Article Abstract:

HIV subtype E that uses the CCR5 receptor appears to be predominate in Cambodia. The CCR5 cell receptor is a receptor on T cells that HIV uses to gain entry into the cell. A survey of 95 HIV-infected Cambodians showed that 89 were infected with subtype E. This subtype is traditionally transmitted via sexual intercourse. Viruses that used the CCR5 receptor were predominant and occurred in half of the patients with advanced disease.

Coreceptor usage of HIV-1 isolates representing different genetic subtypes obtained from pregnant Cameroonian women

Article Abstract:

HIV-1 can use different co-receptors to enter cells, according to a study of 42 HIV-infected women in Cameroon. Subtype A predominated and used CCR5 as a co-receptor. Fourteen percent of viral isolates used the orphan receptor Bonzo and some used both CCR5 and Bonzo.
