The ciliary neurotrophic factor receptor is critically involved in embryonic motor neuron development. Postnatally, it may contribute to neuronal maintenance and regeneration. In addition, pharmacological stimulation of the receptor may slow the progression of several neurodegenerative disorders. The widespread nervous system expression of ciliary(More)
A rapid and sensitive radiometric assay for UDP-glucuronosyltransferase (UGT) is described. UGT substrates are incubated in 96-well plates with microsomes in the presence of [14C]UDP-glucuronic acid, and 14C-labeled glucuronidation products are separated from the unreacted nucleotide sugar by solid-phase extraction using 96-well extraction plates. The assay(More)
Target-derived neurotrophic factors are assumed to regulate motoneuron cell death during development but remain unspecified. Motoneuron cell death in the spinal nucleus of the bulbocavernosus (SNB) of rats extends postnatally and is controlled by androgens. We exploited these features of the SNB system to identify endogenously produced trophic factors(More)
We describe an improved genetic immunization strategy for eliciting a full spectrum of anti-hepatitis C virus (HCV) envelope 2 (E2) glycoprotein responses in mammals through electrical gene transfer (EGT) of plasmid DNA into muscle fibers. Intramuscular injection of a plasmid encoding a cross-reactive hypervariable region 1 (HVR1) peptide mimic fused at the(More)
Since ciliary neurotrophic factor (CNTF) inhibits the production of TNF and activates the hypothalamus-pituitary-adrenal axis (HPAA), we investigated whether CNTF can produce antiinflammatory actions and whether it may act through a central mechanism, using the murine air pouch model of inflammation. In this model, inflammation is evaluated by measuring the(More)
Ciliary neurotrophic factor (CNTF) drives the sequential assembly of a receptor complex containing the ligand-specific alpha-receptor subunit (CNTFR) and the signal-transducing beta-subunits gp130 and leukemia inhibitory factor receptor-beta (LIFR). CNTFR can function in either membrane-bound or soluble forms. The membrane-bound form mediates the neuronal(More)
Human HIV integrase inhibitors are a novel class of antiretroviral drugs that act by blocking incorporation of the proviral DNA into the host cell genome, a crucial step in the life cycle of HIV. In the present work, quantitative methods for prediction of human pharmacokinetics were used to guide the selection of development candidates from a series of(More)
Endogenous injury response mechanisms likely reduce secondary neuronal loss following CNS trauma by activating growth factor receptors. Therefore, it is important to determine which growth factor receptors are activated in vivo by CNS trauma and which signal transduction pathways are affected in which cell types. We present a model of penetrating brain(More)
Leptin is an adipocyte-secreted hormone that regulates body weight and exerts effects on hematopoiesis, reproduction, and immunity. The leptin receptor (OBR) shares sequence similarity and signaling capabilities with receptors for cytokines of the ciliary neurotrophic factor (CNTF) family. Our previous finding that CNTF and leptin exert similar anti-obesity(More)
Regressor serum from MSV-M-infected mice markedly reduced MSV-M oncogenesis when administered i.p. (0-1 ml/mouse) as much as 30 days before i.m. MSV-M infection in adult BALB/c mice. The regressor serum activity appeared to be directly dependent on the amount of IgG, as shown by: (1) inactivity of sera which have low virus-neutralizing antibody content; (2)(More)
