Disrupted In Schizophrenia 1 (DISC1) was identified as a potential susceptibility gene for schizophrenia due to its disruption by a balanced t(1;11) (q42;q14) translocation, which has been shown to cosegregate with major psychiatric disease in a large Scottish family. We have demonstrated that DISC1 exists in a neurodevelopmentally regulated protein complex(More)
The decrease in plasticity that occurs in the central nervous system during postnatal development is accompanied by the appearance of perineuronal nets (PNNs) around the cell body and dendrites of many classes of neuron. These structures are composed of extracellular matrix molecules, such as chondroitin sulfate proteoglycans (CSPGs), hyaluronan (HA),(More)
5-Hydroxytryptamine exerts modulatory physiological effects on both the central and peripheral nervous systems by activation of discrete receptor families. 5-ht(5A) is among the recently cloned, novel 5-HT receptors and currently under investigation to identify its pharmacological characteristics and potential physiological function(s). In this study,(More)
Recent cloning studies have isolated receptors which confer specific responsiveness to calcitonin gene related peptide (CGRP) and the related peptide adrenomedullin. Using in situ hybridisation, we demonstrate the heterogenous distribution of the mRNAs of two proposed CGRP1 receptors (RDC-1 and calcitonin receptor-like receptor, CRLR) in the rat brain.(More)
Many major physiological changes occur within the rodent central nervous system (CNS) during the first few postnatal weeks. These include axonogenesis, synaptogenesis and myelination. Concomitant with CNS development over this period, there is a decrease in susceptibility to many neurotropic virus infections in that infection of suckling animals results in(More)
G protein-coupled receptors are usually thought to act as monomer receptors that bind ligand and then interact with G proteins to initiate signal transduction. In this study we report an intracellular peripheral membrane protein named the calcitonin gene-related peptide (CGRP)-receptor component protein (RCP) required for signal transduction at the G(More)
Transient receptor potential channel proteins (TRPs) constitute a steadily growing family of ion channels with a range of purported functions. It has been demonstrated that TRPV2 is activated by moderate thermal stimuli and, in the rat, is expressed in medium to large diameter dorsal root ganglion neurons. In this study, antisera specific for the human(More)
The precise involvement of 5-ht(5A), 5-ht(5B), 5-ht(6) and 5-HT(7) receptors in the pleiotropic actions of 5-HT remain incompletely known. To gain insights into their physiological function(s), localization of mRNAs encoding these subtypes was carried out using in situ hybridization on rat brain sections. Localization was heterogeneous. For example,(More)
Many neurotropic virus infections have been shown to be virulent in neonatal and suckling mice but avirulent in weaned mice. The neurotropic alphavirus Semliki Forest virus is a well-studied example of this and importantly the age-related change in neurovirulence of this virus has been shown to be independent of specific immune responses. During the first(More)
The heterodimeric CGRP receptor requires co-expression of calcitonin receptor-like receptor (CRLR) and an accessory protein called receptor activity-modifying protein (RAMP) 1 (McLatchie, L. M., Fraser, N. J., Main, M. J., Wise, A., Brown, J., Thompson, N., Solari, R., Lee, M. G., and Foord, S. M. (1998) Nature 393, 333-339). Several non-peptide CGRP(More)
