choline acetyltransferase/necrosis

Tumour necrosis factor alpha (TNF-alpha) is a pleiotrophic cytokine synthesized primarily by macrophages and monocytes, which exerts a variety of biological activities during inflammatory responses, immune reactions, and wound healing. Within the central nervous system (CNS), the basal levels of

Inflammation and reduced forebrain norepinephrine are features of Alzheimer's disease that may interact to contribute to the degeneration of specific neural systems. We reproduced these conditions within the basal forebrain cholinergic system, a region that is vulnerable to degeneration in

Cell death of cholinergic neurons of the basal forebrain plays an important role in neurodegenerative disorders, such as Alzheimer's disease. Inflammatory cytokines, such as, for example, tumor necrosis factor-alpha (TNF-alpha), may be involved in these neurodegenerative processes. The aim of this

Acetylcholine (ACh), synthesized by choline acetyltransferase (ChAT), and muscarinic M(1), M(2), and M(3) receptors (MRs) are involved in fibroblast proliferation. We evaluated ChAT, MRs, and extracellular signal-regulated kinase (ERK) 1/2 and nuclear factor (NF) kappaB activation in lung

It is not known to what extent a non-neuronal cholinergic system is involved in myositis (muscle inflammation) evoked by marked muscle overuse. Therefore, in the present study, a recently established rabbit myositis model was used and the expression patterns of ChAT and nicotinic acetylcholine

Insulin and insulin-like growth factors (IGFs) are the only known trophic factors for pontine cholinergic neurons. The present study revealed that astrocyte-extract pretreated with IL-1β and TNF-α significantly enhanced choline acetyltransferase (ChAT) activity of the pontine neurons in the presence

The present study was conducted to explore the source of acetylcholine (ACH) in the corpus luteum (CL) and to test our hypothesis of an antiapoptotic role of ACH in the bovine CL and, further, to investigate whether nerve growth factor (NGF), insulin-like growth factor 1 (IGF1), and transforming

BACKGROUND NIK- and IKK2-binding protein (NIBP)/TRAPPC9 is expressed in brain neurons, and human NIBP mutations are associated with neurodevelopmental disorders. The cellular distribution and function of NIBP in the enteric nervous system (ENS) remain unknown. METHODS Western blot and reverse

6-Hydroxydopamine (6-OHDA) was injected into the air sac of developing chicken embryos on day E3 in order to study its effects on cardiac development both morphologically and biochemically. A dose-dependent teratogenic effect and fetotoxicity were observed in the 6-OHDA-treated embryos. Cardiac

Effects of immune cytokines on neuronal gene expression have recently been examined in cultured superior cervical (sympathetic) ganglia, a widely used model system for the study of neurotransmitter plasticity. Following deafferentation and explantation into culture, interleukin-1 causes an

The 50-kDa secreted glycoprotein pigment epithelium-derived factor (PEDF) is neuroprotective for various types of cultured neurons, but whether it is neuroprotective for neurons in vivo is not known. We examined the effects of adenovirus-mediated gene transfer of PEDF on quinolinic acid (QA)-induced

Neuroinflammation, and elevated levels of inflammatory proteins, such as tumor necrosis factor-alpha, and the deposition of beta-amyloid may interact to contribute to the pathogenesis of Alzheimer's disease. We reproduced a component of the neuroinflammatory state within the basal forebrain

The etiological initiators of neuroinflammation remain inconclusive, and effective interventions to block neurodegeneration are unavailable. Surprisingly, we found collagen II-combined complete Freund's adjuvant (CC) that usually induces rheumatoid arthritis (RA) also drives Alzheimer's disease

Diisopropylphosphorofluoridate (DFP), an irreversible inhibitor of acetylcholinesterase (AChE) activity, when given as an acute dose (1.5 mg/kg, sc) caused fasciculations and induced necrosis in rat skeletal muscle fibers. No adaptation was seen to daily dosing of DFP (1.5 mg/kg, sc) since all rats
