Sympathetic and neural-crest derived sensory neurons consisting of unmyelinated and small myelinated fibers are known to be affected at an early stage in diabetes mellitus (DM). Since these peripheral neurons need nerve growth factor (NGF) for their development and maintenance of function in adulthood, changes in endogenous NGF levels could be of relevance(More)
The neurotrophins nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) are important mediators of brain and neuronal development, the maintenance of homeostatic conditions in the adult nervous system, and the complex interplay of central and peripheral physiological and pathophysiological factors. To date there are few studies examining(More)
There is increasing evidence that in Alzheimer's disease nerve growth factor (NGF) protein and NGF mRNA content in postmortem cortex is not decreased, but may even be elevated although the NGF-sensitive cholinergic basal forebrain neurons are preferentially affected. However, only little is known about the early pathophysiological events leading to(More)
Long-term effects of ethanol consumption on endogenous nerve growth factor (NGF) level were investigated in NGF-producing target organs and tissues of the peripheral nervous system. Rats were treated with ethanol (20% v/v) for 9 months, detoxified for an additional 2 weeks and kept without ethanol for an additional month prior to sacrifice. NGF level in the(More)
In der Studie wird untersucht, ob neuropsychologische Tests und klinische Demenzskalen eine Aussage über die Einwilligungsfähigkeit von dementen Patienten erlauben. Bei 18 Patienten mit einer Demenz (ICD-10: F00-F03) wurde im Rahmen der ambulanten Demenzdiagnostik neben einer ausführlichen psychiatrischen und neuropsychologischen Untersuchung die(More)
There is increasing evidence that deprivation of the retrogradely transported neurotrophic protein nerve growth factor (NGF) accounts for some functional deficits known to occur in experimental diabetic neuropathy. Here we have studied changes in the axonal transport of endogenous NGF, NGF receptor (NGFR), and NGFR saturation (NGF/NGFR ratio) in the rat(More)
After an untreated 5-month duration of streptozotocin (STZ)-induced diabetes mellitus (DM), nerve growth factor (NGF) levels in BDE rats were decreased to 45-65% of control in the sympathetically innervated target organs iris and submandibular gland, in the superior cervical ganglion (containing NGF-dependent sympathetic perikarya projecting to the cranial(More)
