AB  - The neural cell adhesion molecule (NCAM)-derived peptide FG loop (FGL) modulates synaptogenesis, neurogenesis, and stem cell proliferation, enhances cognitive capacities, and conveys neuroprotection after stroke. Here we investigated the effect of subcutaneously injected FGL on cellular compartments affected by degeneration and regeneration after stroke due to middle cerebral artery occlusion (MCAO), namely endogenous neural stem cells (NSC), oligodendrocytes, and microglia. In addition to immunohistochemistry, we used non-invasive positron emission tomography (PET) imaging with the tracer [18F]-fluoro-L-thymidine ([18F]FLT) to visualize endogenous NSC in vivo. FGL significantly increased endogenous NSC mobilization in the neurogenic niches as evidenced by in vivo and ex vivo methods, and it induced remyelination. Moreover, FGL affected neuroinflammation. Extending previous in vitro results, our data show that the NCAM mimetic peptide FGL mobilizes endogenous NSC after focal ischemia and enhances regeneration by amplifying remyelination and modulating neuroinflammation via affecting microglia. Results suggest FGL as a promising candidate to promote recovery after stroke.
