Development of morphological types and distribution patterns of amacrine cells immunoreactive to tyrosine hydroxylase in the cat retina

Abstract: Using an antibody against tyrosine hydroxylase on newborn to 30-day kitten retinas, we have been able to follow the development of the dopaminergic amacrine cells of the cat retina by light-microscopical investigations of retinal wholemounts. The Type 1 or large Toh+ amacrine cells described by others (Oyster et al., 1985;Tork & Stone, 1979) and named A18 from a Golgi study (Kolb et al., 1981), is at birth (PI) an immature neuron with a small cell body and two or three simple thick radiating dendrites stratify… Show more

“…4). Finally, in some species, DA cell processes appear to give rise to a fourth plexus in the deepest region of the IPL (Nguyen-Legros et al 1981, 1982, rat, M. fascicularis; Hokoç and Mariani 1987, 1988 cat, rabbit; Dacey 1990, M. mulatta; Kolb et al 1990, cat; Tauchi et al 1990, rabbit; Wang et al 1990, cat), where they synapse with the dendrites of AII amacrines (Kolb et al 1990). Occasionally, the deep processes of DA cells, after a tangential course of several hundred micrometers, ascend back to S1.…”

“…DA cell processes in S3 could be the recipients of the ON-cone bipolar synapses, but there is a confounding circumstance that complicates the interpretation of the observations quoted above: Most of the descriptions of DA cells are based on immunocytochemical demonstration of tyrosine hydroxylase (TH), the rate limiting enzyme in dopamine biosynthesis, and the retina contains a second type of TH-positive neuron, the type 2 catecholaminergic amacrine (CA) cell, whose single dendrite gives rise to an arbor residing in the S3 stratum (Mariani and Hokoç 1988, M. mulatta; Wang et al 1990, cat). This type of neuron, however, exhibits a smaller perikaryon than DA cells and is less intensely stained by antibodies to TH.…”

“…This contrasts with the protracted expression of NPY and somatostatin in ganglion cells, as well as the expression of other neuroactive substances within amacrine cells. For example, cholinergic amacrine cells (ChAT-immunoreactive) dramatically increase in number during postnatal development (Dann, 1989), and a transient population of approximately 40,000 morphologically distinct tyrosine-hydroxylase immunoreactive amacrine cells disappear by the third postnatal week (Wang et al, 1990). The cells documented here show no such transcience or protracted expression before their adult complement is reached.…”
