  A selected set of these new derivatives was then used for functional assays at the human A1AR showing, as expected, an antagonist profile with IC50 values at nanomolar level. The same molecules showed also to be efficacious as nanomolar antagonists in a functional assay aimed at analyzing their abil

  Functional consequences of ADK regulation on neuronal excitability Adenosine modulates neuronal excitability via activation of the high affinity A1 or A2A, low-affinity A2B, or low abundance A3 adenosine receptors that feed into a multitude of different neuronal and astrocytic pathways (Blum et

  This study was funded and supported by Tehran University of Medical Sciences and Health Services; and Iran National Science Foundation. Introduction The enzyme acetylcholinesterase (AChE) plays a central role in the signal transduction in the nervous system, hydrolyzing the neurotransmitter acet

  2024-02-06

  

  It has been recognized for decades that neurons in the mammalian central nervous system may release both a fast-acting, typically amino acid derived neurotransmitter such as glutamate or GABA, and a second peptidergic neuromodulatory molecule such as neuropeptide Y, substance P, or cholecystokinin.

  Phosphorylation of P450c17 – Initial studies In addition to the molar ratio of POR to P450c17 and the allosteric action of cytochrome b5, a third factor that governs 17,20 lyase activity is the serine/threonine (Ser/Thr) phosphorylation of P450c17 itself. In a search for post-translational factor

  2024-02-05

  

  The known crystal structures of class C GPCR VFTs do not include attached TM domains, therefore current conformational data may not accurately reflect the dynamics of extracellular domains in full-length receptors. Nevertheless, compelling mechanisms of signal transduction can still be postulated. S

  Cell surface metalloproteases coordinate signaling during development, tissue homeostasis, and disease. A disintegrin and metalloprotease 17 (ADAM17) is a well-characterized member among ADAM family, which mediates the cleavage of various cell surface proteins (Black, 2002, Black et al., 1997, Dello

  Furthermore, to address the concern that the observed positive in vitro activity results might be stymied by the propensity of such assays to display false positives due to the inherent noxiousness of the tested compounds, all analogs were evaluated against Vero cells in an MTT assay. Some of the mo

  Discussion Here, we show opposing effects of iontophoretically administered phenylephrine,aselective α1-AR agonist, on firing of putatively DAergic and non-DAergic neurons recorded in vivo in the VTA of urethane anaesthetized rats. Phenylephrine application caused a relatively weak decrease in fi

  In conclusion, this study detected the expression of adiponectin and its receptors, AdipoR1 and AdipoR2, in goat ovarian follicles. In addition, adiponectin was shown to enhance the progression of goat oocyte nuclear maturation in vitro. The present findings provide evidence for paracrine/autocrine

  In order to get a better understanding of this synergy, we tested the effect of preliminary incubation of L-693,403 maleate with non-stimulating concentrations of gonadotropins or FSK before subsequent stimulation by FSK or gonadotropins alone, also at sub-stimulating concentrations. We observed tha

  ACK1 can be localized to clathrin-coated vesicles [1]. The association of SNX9 with synaptojanin-1 would suggest the two cooperate during endocytosis at the synapse by coupling the sorting nexin to changes in phospholipid composition. ACK1 in turn negatively regulates the association of SNX9 with ta
