“…Interestingly, anti-TNF treatment, but not anti-IL17, anti-IL12 or anti-IL23 treatments, can induce body-weight increase in patients with psoriasis (Esposito et al, 2009, Gisondi et al, 2013, Gisondi et al, 2008a, Patsalos et al, 2020, Shi et al, 2021, Wu et al, 2020, indicating that TNFα may play a unique role in suppressing adipocyte growth. Indeed, TNFα is known to inhibit adipogenesis and induce adipocyte lipolysis (Cawthorn and Sethi, 2008), and therefore it is likely that TNF blockage may promote J o u r n a l P r e -p r o o f 16 weight gain by restoring adipogenesis and inhibiting lipolysis.…”
