Indeed, SIV-infected sooty mangabeys may be spared, by their failure to mount significant antiviral immune responses, much of the indirect bystander damage seen in pathogenic primate lentivirus infections that both contributes to accelerated CD4 depletion and compromises host immune regenerative capacity.
