Recent studies have found that increased level of GLP-1 in the hippocampus restores GABA and reverses this neurotoxic effect by reducing oxidative stress through the SIRT1/Nrf2/HO-1 pathway, promoting autophagy through the AMPK/mTOR pathway, and alleviating hippocampal apoptosis by inactivating pro-apoptotic kinase GSK-3 ( The anorectic effects of GLP-1 can also be explained by its GABAergic modulation in the nucleus tractus solitarius (NTS) cells
After incubation for 16 hrs at 37C, the percentage of infected cells was determined by a direct immunofluorescence assay using FITC-conjugated rabbit anti-herpes simplex virus type 2 immunoglobulins (Dako)
