Key result
C-phycocyanin reduces pro-inflammatory cytokines and leptin while modulating brown fat UCP1 in high-fat diet-fed mice.
Why the study?
Brown adipose tissue plays a key role in energy expenditure and is a promising target for obesity treatment, but the effects of C-phycocyanin on BAT inflammation and thermogenesis are not well understood.
Does C-phycocyanin supplementation improve thermogenic and inflammatory markers in brown adipose tissue of high-fat diet-fed mice?
Does C-phycocyanin supplementation improve thermogenic and inflammatory markers in brown adipose tissue of high-fat diet-fed mice?
C-phycocyanin supplementation may improve brown adipose tissue function and reduce inflammation in a high-fat diet mouse model of obesity.
CPC may curb diet-induced weight gain in mice; hypothesis-generating for obesity therapies and should not yet change practice.
C-phycocyanin (CPC), a bioactive compound derived from Spirulina, has been described as a molecule with antioxidant and anti-inflammatory properties. It has also been demonstrated that sustainably obtained CPC effectively inhibited body mass gain, regulated serum leptin and resistin levels, and prevented the onset of a pro-inflammatory state in Swiss mice fed a hyperlipidic diet. These results highlighted the anti-obesogenic potential of CPC. Brown adipose tissue (BAT) has been identified as a promising target in the treatment of obesity, playing a role in energy expenditure. In this study, Swiss mice fed a high-fat diet were supplemented with 500 mg/kg body weight of CPC daily for 12 and 16 weeks. BAT was collected, and Western blot and ELISA were performed. A reduction in pro-inflammatory cytokines, as well as a decrease in leptin levels was observed in the tissue, which was also associated with a reduction in BAT relative weight to body mass. Furthermore, CPC administration was able to modulate uncoupling protein 1 (UCP1) levels, which is crucial in the thermogenesis process. Therefore, this study demonstrated that supplementation with CPC reduces inflammatory cytokines associated with detrimental effects in the BAT, emerging as a tool in combating obesity and improving BAT function.

Neto et al. (2025) studied Obesity. C-phycocyanin (CPC) was evaluated on Pro-inflammatory cytokines, leptin levels, BAT relative weight, and UCP1 levels. Supplementation with C-phycocyanin reduced pro-inflammatory cytokines and leptin levels, and modulated UCP1 levels in the brown adipose tissue of high-fat diet-fed mice.
