However, the PHI group did exhibit stronger T helper cell responses, which led the researchers to suggest that "individuals treated in early infection may benefit from [therapeutic] strategies aimed at enhancing virus-specific CTL responses, whereas individuals treated later in infection may benefit from strategies aimed at enhancing HIV-1-specific T helper cell functions as well as broadening CTL responses to combat increased viral diversity." Decreased CTL activity had also been observed in early-disease patients who had been treated from 45 to 90 days after symptomatic acute infection, according to a study published 2 years earlier by researchers from the Aaron Diamond AIDS Research Center (ADARC) in New York and colleagues.
