Immunocytochemical identification and analysis of the diffuse bipolar cell type DB6 in macaque monkey retina

Eur J Neurosci. 2001 Feb;13(4):829-32. doi: 10.1046/j.0953-816x.2000.01449.x.


The distribution and morphology of CD15-immunoreactive bipolar cells were studied in the retina of macaque monkey. Labelled cells have a large dendritic tree contacting several cones and a narrowly stratified axon terminal that ends deep in the inner plexiform layer, close to the ganglion cell layer. The morphology of the labelled cells corresponds to that of the diffuse bipolar cell type named DB6 by Boycott & Wässle (1991; Eur. J. Neurosci., 3,1069). We conclude that CD15 is a marker for DB6 bipolar cells, enabling the quantitative analysis of the distribution and connectivity of this diffuse bipolar cell type.
