WebJul 1, 2024 · However, intratumoral Treg depletion in MHCII ΔProx-1 mice did not affect effector T-cell densities, suggesting that Tregs were already dysfunctional in the absence of MHCII expression in LECs. RNA-seq data demonstrated that Treg transcriptomics were profoundly affected in tumors, but not in TdLNs, by the loss of MHCII in LECs. WebThe origin of intratumoral Treg cells and their relationship with peripheral blood Treg cells remain unclear. Treg cells consist of at least three functionally distinct subpopulations.
