Immunocytochemical demonstration of taurine in the retina and pineal organ of the pigeon

Immunocytochemical Localization of Taurine in the Pineal Organ and Retina of an Anadromous Fish, Plecoglossus altivelis.

“…According to LAKE and VERDONE-SMITH (1989), however, taurine-like immunoreactivity is intense in the inner segments and synaptic terminals of most rod cells in rat retina and in the outer and inner segments of cone cells in guinea pig retina. In the cone dominated retina of the pigeon, in addition, the most intense taurine immunoreactivity is demonstrated in the outer and inner segments, and the perikarya and terminal endfeet of the cone cells (DECK et al, 1995).…”

“…High levels of taurine immunostaining were found in the outer and inner segments and synaptic terminals of some photoreceptor cells; lower levels of immunostaining were reported in the apical processes of pigment epithelium and distal parts of glial cells (LAKE and VERDONE-SMITH, 1989;Pow, 1994). The taurine localization, however, is scarcely known in the photoneuroendocrine pineal organ, except in the case of the pigeon (DECK et al, 1995) and rat (MCNULTY et al, 1992).…”

“…Cellular localization of taurine in the retinal tissues has been investigated using Immunocytochemical methods (LAKE, 1989(LAKE, , 1994LAKE and VERDONE-SMITH, 1989;Pow, 1994;DECK et al, 1995;MARC et al, 1995). High levels of taurine immunostaining were found in the outer and inner segments and synaptic terminals of some photoreceptor cells; lower levels of immunostaining were reported in the apical processes of pigment epithelium and distal parts of glial cells (LAKE and VERDONE-SMITH, 1989;Pow, 1994).…”
