Nikon fluorescence microscope with a 20× objective lens eclipse ni-u
GLP-1 enhances mIPSCs of normal RGCs in a concentration-dependent manner. (A) Schematic illustration of the experimental protocol for continuously recording mIPSCs from an RGC for 28 minutes. Data were statistically analyzed at the following time periods: 6–9 minutes of Ctrl, 15–18 minutes of GLP-1 application, and 25–28 minutes of washout. (B) Micrographs of the same retinal section taken with an infrared interferometric phase <t>microscope</t> (left) and a <t>fluorescence</t> microscope (right), showing a representative Lucifer yellow dye-filled ON-RGC with dendrite arborizations in the proximal part of the IPL. Scale bar: 10 μm. (C) Representative current traces showing the effect of 10 nM GLP-1 on GABAergic mIPSCs of an ON-RGC (top trace) and the mIPSC currents on an expanded time scale (bottom traces). (D, E) Scatterplots of mIPSC frequency and amplitude from individual recordings, demonstrating a GLP-1-mediated reversible increase in mIPSC frequency (D), but not amplitude (E) in ON-RGCs ( n = 10). (F) Representative micrographs showing a typical Lucifer yellow-filled OFF-RGC with dendrite arborizations in the distal part of the IPL. Scale bar: 10 μm. (G) Current traces showing the effect of GLP-1 on mIPSCs of an OFF-RGC. (H, I) GLP-1 reversibly incrased mIPSC frequency (H), but not amplitude (I) in OFF-RGCs ( n = 9). (J) Normalized mIPSC frequency recorded in 26 RGCs. (K) Increases in mIPSC frequencies under GLP-1 concentrations of 5, 10, and 100 nM, but not 0.05, 0.5, or 1000 nM. All data normalized to the control values obtained before GLP-1 application. Cell numbers are marked inside the bars in panels J and K. Data are presented as mean ± SEM; * P < 0.05, ** P < 0.01, *** P < 0.001, determined by one-way repeated measures analysis of variance with Tukey’s multiple comparisons test (D, E, H–J) and paired t -test (K).

(J) Normalized mIPSC frequency recorded in 26 RGCs. (K) Increases in mIPSC frequencies under GLP-1 concentrations of 5, 10, and 100 nM, but not 0.05, 0.5, or 1000 nM. All data normalized to the control values obtained before GLP-1 application. Cell numbers are marked inside the bars in panels J and K. Data are presented as mean ± SEM; * P < 0.05, ** P < 0.01, *** P < 0.001, determined by one-way repeated measures analysis of variance with Tukey’s multiple comparisons test (D, E, H–J) and paired t -test (K).

GLP-1 enhances mIPSCs of normal RGCs in a concentration-dependent manner. (A) Schematic illustration of the experimental protocol for continuously recording mIPSCs from an RGC for 28 minutes. Data were statistically analyzed at the following time periods: 6–9 minutes of Ctrl, 15–18 minutes of GLP-1 application, and 25–28 minutes of washout. (B) Micrographs of the same retinal section taken with an infrared interferometric phase microscope (left) and a fluorescence microscope (right), showing a representative Lucifer yellow dye-filled ON-RGC with dendrite arborizations in the proximal part of the IPL. Scale bar: 10 μm. (C) Representative current traces showing the effect of 10 nM GLP-1 on GABAergic mIPSCs of an ON-RGC (top trace) and the mIPSC currents on an expanded time scale (bottom traces). (D, E) Scatterplots of mIPSC frequency and amplitude from individual recordings, demonstrating a GLP-1-mediated reversible increase in mIPSC frequency (D), but not amplitude (E) in ON-RGCs ( n = 10).
