NFKB1 and psoriasis: We found that PSORI-CM02 suppressed HaCaT cell proliferation by hindering their cell cycle progression at G1 phase, inhibited the expression of proinflammatory cytokines and NF-κB signaling, upregulated CD4+ Foxp3+ regulatory T cells (Tregs) in vivo and promoted their in vitro expansion as well while reducing IL-17 production and ameliorating murine psoriasis.
