Regulatory T cells (Treg) that prevent autoimmune
diseases by suppression of self-reactive T cells may also suppress the
immune response against cancer. In mice, depletion of Treg
by Ab therapy leads to more efficient tumor rejection.
Treg-mediated suppression of antitumor immune responses may
partly explain the poor clinical response to vaccine-based
immunotherapy for human cancer. In this study, we measured the
prevalence of Treg that coexpress CD4 and CD25 in the PBLs,
tumor-infiltrating lymphocytes, and regional lymph node lymphocytes
from 65 patients with either pancreas or breast cancer. In breast
cancer patients (n = 35), pancreas cancer patients
(n = 30), and normal donors (n
= 35), the prevalence of Treg were 16.6% (SE 1.22), 13.2%
(SE 1.13), and 8.6% (SE 0.71) of the total CD4+ cells,
respectively. The prevalence of Treg were significantly
higher in breast cancer patients (p < 0.01) and
pancreas cancer patients (p < 0.01) when compared
with normal donors. In tumor-infiltrating lymphocytes and lymph node
lymphocytes, the Treg prevalence were 20.2% (SE 3.93) and
20.1% (SE 4.3), respectively. Treg constitutively
coexpressed CTLA-4 and CD45RO markers, and secreted TGF-
and IL-10
but did not secrete IFN-
. When cocultured with activated
CD8+ cells or CD4+25- cells,
Treg potently suppressed their proliferation and secretion
of IFN-
. We conclude that the prevalence of Treg is
increased in the peripheral blood as well as in the tumor
microenvironment of patients with invasive breast or pancreas cancers.
These Treg may mitigate the immune response against cancer,
and may partly explain the poor immune response against tumor
Ags.
