Purpose: The objective of this study was analyzing the distribution of the excitatory neurotransmitter glutamate receptor to investigate the function in the retina of the greater horseshoe bat.
Methods: After retinal tissues of adult greater horseshoe bat were cut into 40 μm vertical sections, standard immuno-cytochemical techniques was applied for analysis. Immunofluorescence images were obtained using the Bio-Rad MRC 1024 laser scanning confocal microscope.
Results: AMPA (GluR1-4), Kainate (GluR5-7, KA1-2) and NMDA (1, 2A, 2B) mainly distributed in the inner plexiform layer and outer plexiform layer. KA1 receptors have existed not only plexiform layer but also ganglion cell layer.
Conclusions: The greater horseshoe bat has same neuron and neurotransmitter to mammalian retina. These findings suggest that bat has a functional retina for visual analysis.
