Scientists figure out why HIV-1C subtype replicates faster

A team of scientists from India and America have figured out why HIV-1C subtype is more prevalent than other subtypes of the virus.


The study was conducted in a group of HIV positive persons in India. It was found that viral strains of HIV-1C containing two PTAP domains could dominate viral strains containing only one PTAP domain in the blood of eight persons during follow up.

"This molecular trick may have given HIV-1C a big replication advantage over others. Given the dynamic nature of viral evolution, this trick may be transmitted to other slow-witted cousins through ‘viral recombination’ and may make this new molecular trick a universal problem," explained Dr Udaykumar Ranga, a scientist at Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bengaluru, who led the study.
