GLP-1RAs and osteoclasts The greater degree of bone degradation observed in mice lacking GLP-1R indicates that GLP-1R signaling suppresses osteoclast differentiation and bone resorption.362 In an experimental study in which osteoclast formation and bone resorption were induced in mice through lipopolysaccharide (LPS) administration, researchers discovered that simultaneous treatment with exendin-4 resulted in a significant decrease in the number of osteoclasts, the proportion of bone resorption pits, and the levels of the bone resorption marker CTX compared to injection with LPS alone.363 According to previous reports, exendin-4, a GLP-1RA, has the potential to inhibit LPS-induced osteoclast formation and bone resorption in vivo.363,364 This inhibition is believed to occur through the suppression of LPS-induced TNF- production in macrophages.15 Studies have indicated that GLP-1R KO mice exhibit greater numbers of osteoclasts and greater bone resorption than wild-type controls.364 Additionally, CT analysis revealed that, compared with their wild-type counterparts, hyperlipidemic rats treated with subcutaneous GLP-1 for 3 days exhibited increased bone mass in the femur and vertebrae.365 Diabetic patients have a higher risk of fractures than does the general population.366 Mice with type 1 diabetes (T1D) exhibit a reduction in bone mineral density (BMD) and compromised microstructural integrity.367 The administration of liraglutide also impeded osteoclastic bone formation, thereby inhibiting bone resorption and exerting protective effects on bone health in T1D mice.367 Specifically, liraglutide, both alone and in combination with insulin, effectively suppressed the formation of osteoclasts
