The Effect of Intermittent IL-2 Therapy on CD4 T Cells in the Gut in HIV-1-Infected Patients
2011
We sought to determine the effects of interleukin-2 administered in combination with antiretroviral therapy (ART) on CD4+ T cells in the gut. Lymphocytes from whole blood, colon and terminal ileum of HIV infected adults treated with interleukin-2 and ART or ART alone were examined. There were no differences between groups in the proportion of CD4+ T cells or in expression of CD25 or Ki67 by CD4+T cells in the gut. Although IL-2 administration leads to expansion of peripheral blood CD4+ T cells, there is no alteration in the proportion or activation of CD4+ T cells in the gut mucosa.
