EEF1A1-mediated regulation of inflammatory cytokines in psoriasis: implications for therapeutic strategies
摘要
Psoriasis is a chronic T cell-mediated autoimmune disease characterized by persistent skin inflammation. This study analyzed the GSE47598 dataset from the GEO database to investigate the molecular characteristics of T cells activated in vitro with anti-CD3 and anti-CD28 from peripheral blood mononuclear cells (PBMCs) of psoriasis patients. Gene expression profiling revealed that eukaryotic elongation factor 1 alpha 1 (EEF1A1) was significantly upregulated in activated T cells from psoriasis patients. EEF1A1 was shown to promote the secretion of pro-inflammatory cytokines, including IL-6, IL-22, and TNF-α, contributing to the inflammatory cascade in psoriasis. In an imiquimod-induced mouse model of psoriasis, EEF1A1 expression was markedly elevated in lesional skin and was found to regulate inflammation via the Nuclear factor kappa B (NF-κB) signaling pathway. Targeting EEF1A1 using small interfering RNA (siRNA) reduced inflammatory cytokine levels, highlighting its potential as a therapeutic target. Our findings position EEF1A1 as a potential therapeutic target in psoriasis and warrant further validation in human tissues and in vivo inhibition studies.
