Tyr-701 is a new regulatory site for neurotrophin receptor TrkA trafficking and function

Tropomyosin-related kinase A (TrkA) receptor mediates the effects exerted by nerve growth factor on several subpopulations of neuronal cells. Ligand binding to TrkA induces receptor autophosphorylation on several tyrosine residues and the activation of signaling cascades. In this study, we describe a new site relevant for TrkA regulation, the tyrosine 701 (Y701), which is important for receptor tr

Transmission of stress-induced learning impairment and associated brain gene expression from parents to offspring in chickens

Background. Stress influences many aspects of animal behaviour and is a major factor driving populations to adapt to Changing living conditions, such as during domestication. Stress can affect offspring through non-genetic mechanisms, but recent research indicates that inherited epigenetic modifications of the genome could possibly also be involved. Methodology/Principal Findings. Red junglefowl (

The growth factor response in ischemic rat retina and superior colliculus after brimonidine pre-treatment

The α-2-adrenergic receptor agonist brimonidine has been shown to increase survival of retinal ganglion cells following ischemic injury to the rat retina. Increased expression of growth factors has been suggested to be involved in this action. We investigated expressional changes of growth factors and their receptors following transient retinal ischemia induced by selective ligature of ophthalmic

GDNF, Ret, GFRα1 and 2 in the adult rat retino-tectal system after optic nerve transection

In the present study, we have studied the expression of glial cell line-derived neurotrophic factor (GDNF) and its receptors Ret, GFRα1, and GFRα2 in the retino-tectal system before and after optic nerve transection. Using retrograde neuronal tracing in combination with in situ hybridization, we found that Ret and GFRα1 are expressed by 13-14% of the retinal ganglion cells (RGCs). These Ret-expres

Proopiomelanocortin and melanocortin receptors in the adult rat retino-tectal system and their regulation after optic nerve transection

The aim of this study was to characterise the expression of the melanocortin system in the normal and injured rat visual system. Using real-time polymerase chain reaction and immunohistochemistry, we detected melanocortin MC3, MC4 and MC5 receptors and proopiomelanocortin in adult retina and superior colliculus. Melanocortin MC4 receptor mRNA was the most abundant receptor. Melanocortin MC3, MC4 a

Rat retinal ganglion cells upregulate the pro-apoptotic BH3-only protein Bim after optic nerve transection

Increased expression of Bim, a pro-apoptotic member of the Bcl-2 family, has been shown to be critical for neuronal apoptosis. To study the involvement of Bim in injury-induced cell death in retina, Bim expression was studied in normal rat retina and in retina after optic nerve transection using quantitative RT-PCR and immunohistochemistry. As a complement to this, the apoptotic regulators Bax, Bc

Single cell RT-PCR analysis of tyrosine kinase receptor expression in adult rat retinal ganglion cells isolated by retinal sandwiching

We describe a protocol for analysis of gene expression in single, acutely dissociated adult rat retinal ganglion cells using RT-PCR. Retrograde tracing of retinal ganglion cells from the superior colliculi was conducted using Fluorogold. Retinas were dissected and ganglion cells isolated using retinal layer separation (sandwiching). Single, fluorescently labelled retinal ganglion cells were aspira

Overlapping and specific patterns of GDNF, c-ret and GFRα mRNA expression in the developing chicken retina

GDNF and the GDNF receptors, c-Ret, GFRα1 and 2 mRNA is expressed in the developing chicken retina. GDNF labelling was mainly found in embryonic day 4-5 retina but weak labelling could also be found over scattered retinal cells at later stages. c-ret labelling was found over ganglion cells, amacrine and horizontal cells; the preferred GDNF receptor (GFRα1) over amacrine and horizontal cells; and t

Culture and personality disorders : Self-harm in Sweden: A national response with treatment implications for those with or without borderline perso- nality disorder

Objectives: The purpose of this presentation is to discuss Sweden’s national recommendations for mental health treatment provided to self-harming individuals in the country. The recommendations were based upon a Self-Harm Quality Standard (2013) published by the National Institute for Health and Care Excellence (NICE) adapted to Swedish health care and cultural context. Methods: A review and synt

Brief Admission Skåne (BAS), an intervention for indivi- duals with symptoms of borderline personality disorder, recurrent self-harm, at high risk for suicide. : Brief admission Skåne: Evaluation of fidelity to the method and individual-therapist experiences

Objectives: To measure treatment fidelity and to evaluate patient and clinician experiences with Brief Admission Skåne (BAS) over the pilot phase and first five months of the intervention phase of a randomized controlled trial (RCT) testing BAS. The purpose of the RCT is to determine whether BAS can reduce the frequency of acute psychiatric admissions for individuals with borderline personality di

Science - policy interfaces in impact assessment procedures

Modelling tools used in impact assessment procedures can be regarded as tools for communication between science and policy. In order to create an integrated system for modelling not only the scientific components have to be in place but also the science/policy interfaces in the assessment procedures have to be identified and their social dynamics understood.To make a system like SEAMLESS Integrate
