Until recently, human cytomegalovirus (hCMV) infection and anti-CMV treatment in transplanted patients have been monitored essentially by pp65 antigenemia, which is time-consuming and requires experienced operators. For the last two years, pp65 antigenemia levels have tended to be lower than previously in our laboratory, which could be due to better(More)
The binding of the novel radioligand, [3H]-rat urocortin to homogenates of rat cerebellum and homogenates of cells stably transfected with the human CRF1, rat CRF2alpha and rat CRF2beta receptors was examined. In each case, specific reversible high affinity binding was observed (K[d]s between 0.18 and 0.31 nM). The density of sites was relatively low in the(More)
Corticotropin releasing factor (CRF) receptors belong to the super-family of G protein-coupled receptors. These receptors are classified into two subtypes (CRF1 and CRF2). Both receptors are positively coupled to adenylyl cyclase but they have a distinct pharmacology and distribution in brain. Two isoforms belonging to the CRF2 subtype receptors, CRF2alpha(More)
Ro 19-6327 (lazabemide, L), MDL 72974, selegiline, AGN 1135 and MDL 72145 were investigated for their MAO inhibitory effect in rat tissues in vitro. The selectivity of MAO-B inhibition of L, selegiline and MDL 72974 was also measured in vitro in human brain tissue as well as ex vivo in rat brain and liver after acute and subchronic administration. Of all(More)
We report on a comparison of the kinetics of [125I][Tyr0]corticotropin releasing factor (CRF) and [125I][Tyr0]urocortin binding to the CRF binding protein (CRF-BP) at physiological temperature. The association rates of [125I][Tyr0]urocortin or [125I][Tyr0]CRF binding to the CRF-BP were similar. The half time of association for [125I][Tyr0]urocortin was 3.2(More)
We present the pharmacological characterisation of the recombinant human corticotropin releasing factor binding protein (hCRF-BP) using a simple assay. In this assay we employed [3H]urocortin as the radioligand and, as a means to separate bound and free ligand, adsorption to activated charcoal. Using this method, approximately 60-70% of total binding was(More)
