GLP1R and myeloid sarcoma: Because the expression of GLP-1R in myelin-forming oligodendrocytes has been implicated (Smith et al., 2022) and the stimulatory effects of GLP-1RAs on Schwann cells and OECs have been delineated (Pan et al., 2020; Takaku et al., 2021; Tseng et al., 2021), it seems plausible that the agents can directly act on oligodendrocytes and their progenitor cells to promote remyelination under MS conditions.
