More specifically, researchers observed rapid and sustained immunological reconstitution in terms of CD4 and CD8 lymphocyte counts and high frequencies of specific CD4+ and CD8+ cells against microbial agents together with a significant reduction in post-transplant cytomegalovirus reactivation.

In order to define the target antigens and the relative immunodominance of the overall HIV-1-specific CD4 T cell response in clade C virus infection, we used an IFN-γ Elispot assay to screen for HIV-1-specific CD4+ responses using an overlapping peptide set spanning the entire HIV-1 clade C proteome in 32 randomly selected subjects.
