Caffeic acid phenethyl ester inhibits nuclear factor-kB and protein kinase B signalling pathways and induces caspase-3 expression in primary human CD4+ T cells

Wang et al, 2009, Clin Exp Immunol

The inhibitory effect of CAPE results in the inhibition of cytokine production and proliferation in primary human CD4+ T cells

Se pretrattiamo con CAPE (ac. Caffeico) l’effetto è di minore intensità.

The results of this study suggest that natural propolis extracts may prevent TGF-β1-induced EMT in alveolar cells, which may be clinically applied in the prevention and/or treatment of EMT-related fibrotic diseases as well as airway remodeling in chronic asthma
