Notably, tirzepatide observably increased the abundance of beneficial genera such as Akkermansia, elevated the ratio of farnesoid X receptor (FXR) antagonists (glycoursodeoxycholic acid: GUDCA, -muricholic acid: -MCA, hyodeoxycholic acid: HDCA, ursodeoxycholic acid: UDCA) to natural agonists (cholic acid: CA, lithocholic acid: LCA, chenodeoxycholic acid: CDCA, glycocholic acid: GCA, taurodeoxycholic acid: TDCA), and reduced FXR expression in intestinal tissues
The beneficial effect of tirzepatide on hsCRP, a biomarker of systemic inflammation, YKL-40, a proinflammatory cytokine, and ICAM-1, a biomarker of endothelial dysfunction, was already detectable at 4 weeks, consistent with the salutary effects of GIP and GLP-1 on inflammation and atherosclerosis in experimental models [84,85,86]
Nicotine is a paradox: it acutely sharpens attention via nicotinic receptors but dependence and withdrawal reliably fog memory and concentration and a 2024 Psychopharmacology review links e-cigarettes to impaired memory and decision-making even in never-smokers
