WebMixed lymphocyte reaction Test your immunomodulatory drug by measuring effects on T cell proliferation in a mixed lymphocyte reaction (MLR). The MLR is based on an allogeneic immune reaction that occurs when lymphocytes of two different donors are co-cultured, resulting in T cell activation. WebBy utilizing a mixed lymphocyte culture reaction, a clone strain of Th cell (Th21 cell), producing IL-21 and IFNγ but not producing IL-17, is successfully established. 例文帳に追加 混合リンパ球培養反応を利用して、IL−21及びIFNγを産生するが、IL−17を産生しないTh細胞（Th21細胞）のクローン株を樹立することに成功した。
