Study summary Full title Chronic myeloid leukemia-derived extracellular vesicles increase Foxp3 level and suppressive activity of thymic regulatory T cells. All authors Swatler J, Dudka W, Bugajski L, Brewinska-Olchowik M, Kozlowska E, Piwocka K. Journal Eur J Immunol Abstract Mechanisms driving immunosuppression in chronic myeloid leukemia are mostly unknown. We show that le (show more...)Mechanisms driving immunosuppression in chronic myeloid leukemia are mostly unknown. We show that leukemic extracellular vesicles (EVs) target lymphocytes and amplify suppressive function of thymic regulatory T cells, by driving expression of Foxp3 transcription factor. This could facilitate expansion of leukemic cells outside the bone marrow, leading to blast crisis.
