ABSTRACT = {CD3+ T lymphocytes were isolated by positive magnetic separation from the peripheral blood of
healthy donors. In the absence of any additional activating stimuli, interleukin-7 (IL-7) was shown to augment
the levels of T cells expressing CD25 activation marker both in CD4-positive and in CD4-negative effector memory
(CD45RA<sup>-</sup>CD197<sup>-</sup>)
T cell subsets, as well as in terminally differentiated (CD45RA<sup>+</sup>CD197<sup>-</sup>) T cells, without
signiﬁcantly affecting the activation status of naive (CD45RA<sup>+</sup>CD197<sup>+</sup>) and central memory (CD45RA-CD197<sup>+</sup>)
T
cells. In addition, IL-7 noticeably enhanced the production of IL-2, interferon-γ (IFN-γ), and IL-10, but not IL-4,
in T cells. The direct effects of IL-7 on T cell activation induced in vitro by MACSiBead<sup>TM</sup> particles coated with
CD2, CD3, and CD28 antibodies (Abs) were also investigated. Upon cell activation, IL-7 signiﬁcantly augmented
the levels of CD25+ T cells in naive (CD45RA<sup>+</sup>CD197<sup>+</sup>), central memory (CD45RA<sup>-</sup>CD197<sup>+</sup>),
and effector memory
(CD45RA<sup>-</sup>CD197<sup>-</sup>)
T-cell compartments. In addition, IL-7 facilitated activation of CD4- (but not CD4<sup>+</sup>) terminally
differentiated effector (CD45RA<sup>+</sup>CD197<sup>-</sup>) T cells. Finally, IL-7 was found to upregulate the production of IL-2,
IFN-γ, IL-4, and IL-10 by activated T cells. In conclusion, we speculate that IL-7 is capable of enhancing functional
T cell activity without causing signiﬁcant functional inbalance between various T cell subsets.},
