Overexpression of tumour necrosis factor alpha in the brain of transgenic mice differentially alters nerve growth factor levels and choline acetyltransferase activity.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

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

The toxicity of tumor necrosis factor-alpha upon cholinergic neurons within the nucleus basalis and the role of norepinephrine in the regulation of inflammation: implications for Alzheimer's disease.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

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

Tumor necrosis factor-alpha triggers cell death of sensitized potassium chloride-stimulated cholinergic neurons.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

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

Smoke, choline acetyltransferase, muscarinic receptors, and fibroblast proliferation in chronic obstructive pulmonary disease.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

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

Choline acetyltransferase and the nicotinic acetylcholine receptor AChRα7 in experimental myositis.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

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

Interleukin-1β and tumor necrosis factor-α co-operatively enhance a novel trophic activity of astrocytes for pontine cholinergic neurons in vitro.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

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

Survival role of locally produced acetylcholine in the bovine corpus luteum.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

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

Expression and function of NIK- and IKK2-binding protein (NIBP) in mouse enteric nervous system.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

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

Ameliorative effect of deoxyvasicine on scopolamine-induced cognitive dysfunction by restoration of cholinergic function in mice.

Aerial parts of Peganum harmala Linn is used as a traditional medical herb for treatment of amnesia in Uighur medicine in China. Deoxyvasicine (DVAS) is one of the chief active ingredients in P. harmala, it possesses strong acetylcholinesterase (AChE) and butyrylcholinesterase (BChE)

6-Hydroxydopamine induced cardiac malformations and alterations of the autonomic nervous system in the developing chicken embryo.

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

Neural-immune interactions in sympathetic ganglia.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

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

Adenoviral gene delivery of pigment epithelium-derived factor protects striatal neurons from quinolinic acid-induced excitotoxicity.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

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

The presence of the APP(swe) mutation in mice does not increase the vulnerability of cholinergic basal forebrain neurons to neuroinflammation.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

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

Alzheimer's Disease-like Early-phase Brain Pathogenesis: Self-curing Amelioration of Neurodegeneration from Pro-inflammatory 'Wounding' to Anti-inflammatory 'Healing'.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

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

Mechanisms of toxicity and tolerance to diisopropylphosphorofluoridate at the neuromuscular junction of the rat.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

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
