Molecular cloning, characterization, and localization of a high-affinity serotonin receptor (5-HT7) activating cAMP formation.
Northern blot and in situ hybridization analyses showed the 5-HT7 transcripts to be expressed in discrete areas of the limbic brain (e.g., pyramidal hippocampus cells, tenia tecta, amygdaloid, or mammillary nuclei), suggesting that the receptor mediates serotoninergic controls in functions like mood, learning, or neuroendocrine and vegetative behaviors.

Evaluation of Histamine H1-, H2-, and H3-Receptor Ligands at the Human Histamine H4 Receptor: Identification of 4-Methylhistamine as the First Potent and Selective H4 Receptor Agonist
Interestingly, 4-methylhistamine is identified as a high-affinity H4R ligand that has a >100-fold selectivity for the hH4R over the other histamine receptor subtypes, of major importance for future studies to unravel the physiological roles of the H 4R. Expand
A novel rat serotonin (5-HT6) receptor: molecular cloning, localization and stimulation of cAMP accumulation.
Cloned a rat cDNA encoding a functional serotonin receptor (5-HT6), its coding sequence corresponds to a glycoprotein of 436 amino acids displaying significant homology with other cloned monoaminergic receptors, e.g., various serotonin receptors. Expand
The histamine H3 receptor: from gene cloning to H3 receptor drugs
relevant information on this target protein is discussed and the development of various H3 receptor agonists and antagonists are described, and their effects in preclinical animal models are described. Expand
Molecular pharmacological aspects of histamine receptors.
The description of pharmacological tools for the H1, H2 and H3 receptor, including the recent cloning of the receptor genes, and their respective signal transduction mechanisms are described. Expand
Identification of rat H3 receptor isoforms with different brain expression and signaling properties.
The identification of these new H3 receptor isoforms and their specific signaling properties adds a new level of complexity to the understanding of the role of histamine, and the H3 receptors in brain function. Expand
Human cytomegalovirus-encoded chemokine receptor US28 promotes tumorigenesis
The studies reveal that expression of US28 induces a proangiogenic and transformed phenotype by up-regulating the expression of vascular endothelial growth factor and enhancing cell growth and cell cycle progression, indicating the importance of constitutive receptor activity in the early onset of tumor development.
