Survival of Dopaminergic Amacrine Cells after Near-Infrared Light Treatment in MPTP-Treated Mice

Figure 1

Outline of the different experimental groups used in this study, namely: Saline, Saline-NIr, MPTP, and MPTP-NIr, in either the simultaneous (a) or posttreatment (b) series of the acute and chronic models. Photomicrographs of TH⁺ amacrine cells in retinal wholemounts of the superior temporal region (c) and of the retinal edges ((d), (e)). The latter reveals the location of the TH⁺ somata and dendrites within the different layers. Most TH⁺ somata were located in the inner layers of the inner nuclear layer (c); very few were located in the ganglion cell layer (e). All images from Saline group of Ac-Sim case. Scale bars = 100 μm.
