the most important risk factors for anxiety disorders include genes, early life stress, and current stress. these factors do not act independently but interact with each other throughout human development through examples such as epigenetic modifications and complex forms of learning. the neural substrate of pathological anxiety includes hyperactivity in the amygdala and other limbic brain regi...
Neuropeptide Y (NPY) receptors (nomenclature as agreed by the NC-IUPHAR Subcommittee on Receptors [158]) are activated endogenous peptides neuropeptide Y, Y-(3-36), peptide YY, PYY-(3-36) and pancreatic polypeptide (PP). The receptor originally identified Y3 has been CXCR4 chemokine recepter (originally named LESTR, [139]). y6 is a functional gene product in mouse, absent rat, but contains fram...
Peripheral autonomic and sensitive neurons projecting to the extrinsic smooth penile musculature of the pig were studied by means of retrograde tracing and single-labelling immunofluorescence methods. The fluorescent retrograde tracer Fast Blue was injected into the left retractor penis muscle, that was taken as an experimental model of the male genital smooth musculature, of 4 castrated pigs. ...
Neuropeptides are a diverse class of intercellular signalling molecules that mediate neuronal regulation of many physiological and behavioural processes. Recent advances in genome/transcriptome sequencing are enabling identification of neuropeptide precursor proteins in species from a growing variety of animal taxa, providing new insights into the evolution of neuropeptide signalling. Here, det...
The intergeniculate leaflet (IGL) of the lateral geniculate complex has widespread, bilateral, and reciprocal connections with nuclei in the subcortical visual shell. Its function is poorly understood with respect to its role in visual processing. The most well-known IGL projection, and the only one with a clear function, is the geniculohypothalamic tract (GHT) that terminates in the suprachias...
We investigated the contractile response of isolated rabbit middle cerebral artery (MCA) segments to electrical field stimulation (EFS). The dynamics of the EFS contraction were compared with a similar-sized branch of rabbit ear artery. In comparison with the ear artery, the EFS contractions of the MCA displayed a longer latency and a higher stimulus frequency threshold. Greater stimulation tra...
PURPOSE To characterize the potential for neuropeptide Y (NPY) signaling in the retinal pigment epithelium (RPE) by identifying the NPY receptor subtypes present, determining the effect of NPY on second-messenger production and membrane conductance, and establishing the neural retina as a site of NPY gene expression. METHODS Neuropeptide Y receptors present in bovine and human RPE were identi...
