GLP1R and psoriasis: A Danish study observed that GLP-1R gene expression was detected in five out of six PsO patients in areas with active psoriatic plaques compared to five out of six PsO patients that had no GLP1R expression in inactive areas and five out of six healthy controls (without psoriasis) that also had no expression of GLP1R, suggesting that GLP1R expression is upregulated in active psoriatic lesions [38].
