Figure 2. Molecular mechanisms of the anti-obesity effects of capsaicin.

Figure 2

(A) Capsaicin can inhibit adipogenesis in preadipocyte and adipocyte by up-regulating the expression of PPARγ and UCP-1. Thus, it will stimulate adiponectin secretion and increase body fat accumulation. (B) Capsaicin can activate BAT activity, accompanied by increased expression of UCP-1 and PGC-1α. (C) Capsaicin can suppress appetite, increase satiety, and ameliorate insulin resistance. (D) Capsaicin can modulate its function in gastrointestinal tract and gut microbiome, including stimulation of GLP-1 secretion and increase in population of the gut bacterium Akkermansia muciniphila. STAT-3, signal transducer and activator of transcription-3.
