...Markus Geissen; Stefan Heller; Diane Pennica; Uwe Ernsberger; Hermann Rohrer ABSTRACT Sympathetic ganglia are composed of noradrenergic and cholinergic neurons. The differentiation of cholinergic sympathetic neurons is characterized by the expression of choline acetyltransferase (ChAT...

.... Tectal interneurons rich in SP receptors are concentrated in the lamina to which SP-positive RGC axons project, and a set of cholinergic (choline acetyltransferase-positive) tectal projection neurons elaborate dendrites in the lamina to which AChR-positive RGC axons project. These populations of tectal...

... mechanism for the regulation of trophic factor production by target cells. To test this notion, we have examined motoneuron survival in vivo and choline acetyltransferase (ChAT) development in vitro following treatment of chick embryos and rat spinal cord cultures with partially purified skeletal muscle...

... hydroxylase (TOH) and choline acetyltransferase (CAT). Total acetylcholinesterase (AcChE) activity increased with NGF concentration, although less distinctly than TOH and CAT. However, NGF caused a large induction of the asymmetric A 12 form of AcChE, and to a lesser extent of the globular G, and G 2 forms...

...Simone Vidal; Brigitte Raynaud; Dominique Clarous; Michel J. Weber ABSTRACT Muscle-conditioned medium (CM) induces choline acetyltransferase (CAT) activity in primary cultures of new-born rat sympathetic neurones and depresses the development of tyrosine hydroxylase (TOH). By following these two...
