We have described in the preceding 2 papers the development of the pharmacological and contractile properties of all targets of the ciliary ganglion: the iris and ciliary body (Pilar et al., 1987), and the choroidal coat (Meriney and Pilar, 1987). In this paper, we examine the chronic effects of ACh receptor (AChR) blockade on ciliary ganglion neuron(More)
Adrenomedullary cells and autonomic ganglion cells originate from the neural crest. Both cell types synthesize, store and release catecholamines; however, their structural and functional properties are distinctly different. Aloe and Levi-Montalcini have shown in vivo that when the adrenal medulla is exposed to exogenous nerve growth factor (NGF) most cells(More)
During development, most cortical neurons migrate to the cortical plate (CP) radially. CP development is abnormal in reeler and other mutant mice with defective Reelin signaling. Reelin is secreted by Cajal-Retzius cells and binds to the very low density lipoprotein receptor and apolipoprotein E receptor type 2 receptors on the surface of CP cells, inducing(More)
Tumor necrosis factor (TNF) is synthesized by macrophages exposed to endotoxin. It produces haemorrhagic necrosis of a variety of tumours in mice and is cytostatic or cytocidal against various transformed cell lines in vitro, but viability of normal human or rodent cells is unaffected. The role of TNF is unlikely to be restricted to the rejection of(More)
