Nerve growth factor (NGF), released by osteoblasts, endothelial cells, and infiltrating immune cells, plays a key role in promoting this ectopic innervation, establishing a direct link between structural bone changes and pain signaling ( via its receptor DCC, has been shown to drive the sprouting of calcitonin gene-related peptide (CGRP)+ nociceptive fibers in the subchondral bone, thereby contributing directly to pain hypersensitivity associated with OA (Zhu et al., 2019)
Compared with GLP-1 drugs, it also stimulated metabolism, particularly fat use
This includes improved mitochondrial function and reduced inflammatory markers
The mechanisms for metal transition ions promoted lipid peroxidation are H 2 O 2 decomposition and direct homolysis of endogenous hydroperoxides
As a result, direct comparisons between ESG, GLP-1 RAs, and MBS are often hindered by methodological inconsistencies
