Ganglion cells

Methanol intoxication can cause blindness due to damage to ganglion cells in the retina. The blindness results from the accumulation of formaldehyde and formic acid, which are metabolites of methanol. Chemical compounds can also damage the visual cortex, for example, visual damage was observed among the victims of organic mercury intoxication in Japan (the fishermen of Minamata Bay). ... [Pg.293]

In addition to changes within the nerve, sympathetic afferents become able to activate sensory afferents via as yet poorly characterised a-adrenoceptors. These interactions between adjacent sensory and autonomic nerve axons and between ganglion cells result in excitation spreading between different nerve fibres. These peripheral ectopic impulses can cause spontaneous pain and prime the spinal cord to exhibit enhanced evoked responses to stimuli, which themselves have greater effects due to increased sensitivity of the peripheral nerves.

In addition to its presence in the RPE, ABCA1 has been found to be localized in the neural retina, particularly in the ganglion cell layer and rod photoreceptor inner segments (Tserentsoodol et al., 2006a), suggesting it may be involved in carotenoid transport throughout the retina. [Pg.321]

A1 adenosine receptors are inhibitory in the central nervous system. A receptors were originally characterized on the basis of their ability to inhibit adenylyl cyclase in adipose tissue. A number of other G-protein-mediated effectors of A receptors have subsequently been discovered these include activation of K+ channels, extensively characterized in striatal neurons [13], and inhibition of Ca2+ channels, extensively characterized in dorsal root ganglion cells [14]. Activation of A receptors has been shown to produce a species-dependent stimulation or inhibition of the phosphatidylinositol pathway in cerebral cortex. In other tissues, activation of A receptors results in synergistic activation of the phosphatidylinositol pathway in concert with Ca2+-mobilizing hormones or neurotransmitters [15]. The effectors of A adenosine receptors and other purinergic receptor subtypes are summarized in Table 17-2. [Pg.313]

Neurotrophin 4/5 is not as well characterized as other members of the neurotrophin family. Much of what is known is derived from analysis of NT4/5 and TrkB knockout mice. Elucidating the actions of NT4/5 is complicated by virtue of the fact that both NT4/5 and BDNF exert their effects via the TrkB receptor. It appears that NT4/5 functions largely overlap with those of other neurotrophin family members, particularly BDNF. NT4/5 knockout mice are essentially normal, in contrast to BDNF knockout mice, which do not live long. NT4/5 is likely to have unique actions on a subpopulation of neurons in the nodose and geniculate ganglia, which are not supported by BDNF. Like BDNF, NT4/5 acts on sensory neurons and retinal ganglion cells, supporting their survival. [Pg.476]
