  "account": "Metabolically activated proteostasis regulators, such as compound AA147, can inhibit the differentiation of CD4+ T helper 17 (TH17) cells. These regulators achieve this by targeting stress-responsive signalling pathways and promoting degradation of the transcription factor RORgammat. This process occurs independently of ATF6 activation and involves the NRF2 pathway, which reduces intracellular reactive oxygen species and suppresses TH17 cell differentiation. Additionally, AA147 decreases the expression of the TCR-responsive factor IRF4, thereby suppressing the production of select effector cytokines across effector T cell subsets. This selective reshaping of TH17 cell identity has the potential to broadly dampen effector cytokine responses in various T cell subsets, offering a promising therapeutic approach.",
  "summary": "The differentiation of naive CD4+ T cells into effector T cell subsets such as TH1, TH2, TH17 and TREG cells is governed by tightly coordinated activation programmes dependent on T cell receptor (TCR) engagement, co-stimulation, and cytokine signalling. This differentiation process involves regulation of stress-responsive signalling pathways such as the unfolded protein response (UPR) and the…",
