Клиническое значение внутриопухолевых Foxp3+ Т-регуляторных клеток при солидных опухолях и фолликулярных лимфомах: обзор литературы и собственные данные

Abstract

Роль Т-регуляторных клеток (Treg) при солидных опухолях заключается в подавлении специфических противоопухолевых Т-клеточных ответов, что способствует злокачественному росту и неблагоприятному прогнозу. При лимфомах из клеток фолликулярных центров Treg служат компонентом реактивного микроокружения фолликулов. Они участвуют в контроле В-клеточной дифференцировки, их действие при фолликулярной лимфоме направлено не только и не столько на Т-цитотоксические лимфоциты, сколько непосредственно на опухолевые В-клетки. Как и в нормальном лимфоузле, Treg способны препятствовать росту и дифференцировке В-клеток зародышевых центров и даже оказывать непосредственное цитотоксическое влияние на них. В целом это может сказываться на улучшении прогноза у больных. Наши предварительные данные с количественной оценкой FOXP3позитивных Т-лимфоцитов у 66 больных фолликулярной лимфомой подтверждают благоприятную прогностическую роль интрафолликулярных клеток FOXP3+.

T-regulatory cells suppress specific anti-tumor immune responses in non-hematological malignancies and thus lead to tumor growth and unfavorable prognosis. In malignant lymphomas arising from follicular center cells T-regulatory cells are directed not only to cytotoxic lymphocytes but also to tumor B-cells. As in normal lymph node T-regulatory cells can suppress growth and differentiation of germinal center B-cells, and even kill them by cytotoxic mechanism. Generally it may have favourable effect, and lead to the improvement of prognosis in patients. We quantitatively studied FOXP3-positive lymphocytes in different microanatomical lymph node compartments of 66 patients with follicular lymphoma and found favourable influence on prognosis of a large number of intrafollicular FOXP3 cells.
