Catecholaminergic neurons are affected in several neurological and psychiatric diseases. Tyrosine hydroxylase (TH) is the first, rate-limiting enzyme in catecholamine synthesis. We report a knockin mouse expressing Cre-recombinase from the 3'-untranslated region of the endogenous Th gene by means of an internal ribosomal entry sequence (IRES). The resulting(More)
This study examined the effects of long-term differential rearing on levels of brain nerve growth factor, its receptors, and their relationships to cognitive function. Adult rats (two months old) were placed into either enriched or standard housing conditions where they remained for 12 months. Animals from the enriched condition group had significantly(More)
In this study we examine whether exposure to differential housing after weaning would counteract the effects of postnatal handling (H) or nonhandling (NH) treatment by affecting learning and memory processes in young rats. In addition, we seek to determine if experience in enriched environment would alter hippocampal nerve growth factor (NGF) levels which(More)
This study examined the behavioural and physiological effects of chronic mild stress on neonatally handled and non-handled rats. Neonatally handled and non-handled rats were exposed to chronic mild stress from weaning time to 6 months of age. They were behaviourally tested at 6 months of age, and sacrificed for analysis of nerve growth factor (NGF) in the(More)
Two methods of providing environmental stimulation that were introduced in the 1950s have guided much research on neurobehavioural plasticity. These are neonatal handling and environmental enrichment. Neonatal handling has been shown to permanently affect behaviour and endocrine responses. Recently this manipulation has been shown to have important(More)
The aim of this study was to investigate the expression of serine/threonine kinase receptors in the brain following traumatic brain injury. We report here that, the recently cloned and characterized bone morphogenetic protein (BMP) receptor type II (BMPR-II) and the activin receptor type IA (ActR-1) Act: mRNAs were simultaneously up-regulated in neurones in(More)
Transforming growth factors-beta (TGF-betas), activins, and bone morphogenetic proteins (BMPs) comprise an evolutionarily well-conserved group of proteins controlling a number of cell differentiation, cell growth, and morphogentic processes during development. The superfamily of TGFbeta-related genes include over 25 members in mammals several of which are(More)
The expression patterns of serine/threonine kinase receptors in the central nervous system of the developing and adult rat were studied by in situ hybridization. The recently cloned bone morphogenetic factor receptor type II (BMPR-II) was compared with the ActR-II and several type I receptors including ActR-I, ActR-IB, BMPR-IA, BMPR-IB and TβR-I. We found(More)
Expression of BMP- and GDF-related factors within the transforming growth factor-beta (TGF-beta) superfamily was examined in the rat and mouse brain by in situ hybridization. Strong signals were obtained in neurons for GDF-1 and GDF-10. GDF-1 is expressed at postnatal day 6 in the cerebral cortex, hippocampal CA1 through CA3 neurons, while only weakly(More)
We have previously cloned a human receptor recently shown to be a cofactor for entry of T-tropic HIV-1 strains into CD4+ cells, now named fusin. Stromal derived factor-1 (SDF-1) is an endogenous ligand for fusin, also called CXCR-4. Here we show the distribution of fusin/CXCR-4 mRNA during ontogeny in the rat. The onset of mRNA expression is around(More)
