We consequently performed multi-color circulation cytometry on peripheral blood mononuclear cells from young and aged beagles, and identified the differential cytokine production by proposed memory space subsets. CD4+ and CD8+ T lymphocytes in aged dogs displayed improved cytokine production, and decreased proliferative capacity. Antibodies focusing on CD45RA and CD62L, but less so CD28 or CD44, defined canine cells that consistently exhibited properties of na?ve-, central memory space-, effector memory space-, and terminal effector-like CD4+ and CD8+ T lymphocyte subsets. Older dogs demonstrated decreased frequencies of na?ve-like CD4+ and CD8+ T lymphocytes, and an increased frequency of terminal effector-like CD8+ T lymphocytes. Overall findings exposed that aged dogs displayed features of BOC-D-FMK immunosenescence much like those reported.
