Ure.com/scientificreports/Figure four. Fluorescence micrographs of retinal sections, labeled yellow-green for LEP-100 or GRL2 and tealblue for nuclei (DAPI); RPE and pigmented structures, which we situated in bright-field photos, are outlined with white dotted lines. In retinas treated using the maximal dose of SNP (a,d), intense LEP-100 and GRL2 signals have been found within the IPL, close to the inner limiting membrane, and inside the choroid; a important amount of red autofluorescence (pseudo-colored pink) was detected in what are most likely the pigmented remnants from the RPE, a number of which had been co-localized with the LEP-100 and GRL2 signals (). In all other tissues tested, there was no important fluorescence within the red channel, and LEP-100 and GRL2 labelling patterns didn’t differ as outlined by remedy group. LEP-100 signal was present within the basal RPE, bacillary layer (PR), putative microglia/macrophage inside the IPL (), and probable astrocytes at the internal limiting membrane ( ) in max L-Arg- and PBS-treated retina (b,c). GRL2 signal was not detected in undamaged retina (e,f).

Nonetheless, this has never been conclusively shown, and as we have argued recently34, several information are inconsistent with atropine-mediated prevention of myopia by competitive inhibition of ACh at retinal mAChRs. Also, the proof for direct interact.
