In this paper, we sought to identify the CD4(+) T-cell dynamics in the course of HIV infection in response to continuous and intermittent intravenous courses of interleukin-2 (IL-2), the principal cytokine responsible for progression of CD4(+) T-lymphocytes from the Cl to the S phase of the cell cycle. Based on multivariate regression models, previous literature has concluded that the increase in survival of CD4(+) T-cell appears to be the critical mechanism leading to sustained CD4(+) T-cell levels in HIV-infected patients receiving intermittent IL-2 therapy. Underscored by comprehensive mathematical modeling, a major finding of the present work is related to the fact that, rather than due to any increase in survival of CD4(+) T-cells, the expressive, selective and sustained CD4(+) T-cell expansions following IL-2 administration may be related to the role of IL-2 in modulating the dynamics of Fas-dependent apoptotic pathways, such as activation-induced cell death (AICD) or HIV-specific apoptotic routes triggered by viral proteins.
