Employing preclinical, ex vivo, in vivo, and in vitro model systems investigators determined that GLP-1 agonists exert anti-inflammatory and immune modulating effects through their effects on macrophages (reduced interleukin [IL] 1, IL-6, tumor necrosis factor [TNF], and C-X-C motif chemokine ligand [CXCL]), T and B lymphocytes (reduced cluster of differentiation [CD] 4 cells), monocytes (increased IL-10), mononuclear cells (decreased monocyte chemoattractant protein [MCP]1, cell death protein [PD],, CD4 and CD8 T cells) [51,52,53,54,55]
A key difference may be the timing of muscle sampling as it is unclear when dissection of the mice was performed relative to the last BA dose ( Muscle carnosine loading is most pronounced during the initial weeks of supplementation, after which increases in muscle carnosine content appear to slow
