TL;DR: The D3 receptor is localized to limbic areas of the brain, which are associated with cognitive, emotional and endocrine functions, and seems to mediate some of the effects of antipsychotic drugs and drugs used against Parkinson's disease.
Abstract: A dopamine receptor has been characterized which differs in its pharmacology and signalling system from the D1 or D2 receptor and represents both an autoreceptor and a postsynaptic receptor The D3 receptor is localized to limbic areas of the brain, which are associated with cognitive, emotional and endocrine functions It seems to mediate some of the effects of antipsychotic drugs and drugs used against Parkinson's disease, that were previously thought to interact only with D2 receptors

TL;DR: In addition to uncovering a new principle of cis-regulatory architecture of mammalian chromosomes, this study sets the stage for the full genetic dissection of the mouse X-inactivation centre.
Abstract: High-order chromatin folding in topologically associating domains has a critical role in proper long-range transcriptional control around the Xist locus, and presumably throughout the genome. The spatial organization of the genome is linked to biological function, and advances in genomic technologies are allowing the conformation of chromosomes to be assessed genome wide. Two groups present complementary papers on the subject. Bing Ren and colleagues use Hi-C, an adaption of the chromosome conformation capture (3C) technique, to investigate the three-dimensional organization of the human and mouse genomes in embryonic stem cells and terminally differentiated cell types. Large, megabase-sized chromatin interaction domains, termed topological domains, are found to be a pervasive and conserved feature of genome organization. Edith Heard and colleagues use chromosome conformation capture carbon-copy (5C) technology and high-resolution microscopy to obtain a high-resolution map of the chromosomal interactions over a large region of the mouse X chromosome, including the X-inactivation centre. A series of discrete topologically associating domains is revealed, as is a previously unknown long intergenic RNA with a potential regulatory role. In eukaryotes transcriptional regulation often involves multiple long-range elements and is influenced by the genomic environment1. A prime example of this concerns the mouse X-inactivation centre (Xic), which orchestrates the initiation of X-chromosome inactivation (XCI) by controlling the expression of the non-protein-coding Xist transcript. The extent of Xic sequences required for the proper regulation of Xist remains unknown. Here we use chromosome conformation capture carbon-copy (5C)2 and super-resolution microscopy to analyse the spatial organization of a 4.5-megabases (Mb) region including Xist. We discover a series of discrete 200-kilobase to 1 Mb topologically associating domains (TADs), present both before and after cell differentiation and on the active and inactive X. TADs align with, but do not rely on, several domain-wide features of the epigenome, such as H3K27me3 or H3K9me2 blocks and lamina-associated domains. TADs also align with coordinately regulated gene clusters. Disruption of a TAD boundary causes ectopic chromosomal contacts and long-range transcriptional misregulation. The Xist/Tsix sense/antisense unit illustrates how TADs enable the spatial segregation of oppositely regulated chromosomal neighbourhoods, with the respective promoters of Xist and Tsix lying in adjacent TADs, each containing their known positive regulators. We identify a novel distal regulatory region of Tsix within its TAD, which produces a long intervening RNA, Linx. In addition to uncovering a new principle of cis-regulatory architecture of mammalian chromosomes, our study sets the stage for the full genetic dissection of the X-inactivation centre.

TL;DR: It is proposed that downstream topographical biomarkers of the disease, such as volumetric MRI and fluorodeoxyglucose PET, might better serve in the measurement and monitoring of the course of disease.
Abstract: In the past 8 years, both the International Working Group (IWG) and the US National Institute on Aging-Alzheimer's Association have contributed criteria for the diagnosis of Alzheimer's disease (AD) that better define clinical phenotypes and integrate biomarkers into the diagnostic process, covering the full staging of the disease. This Position Paper considers the strengths and limitations of the IWG research diagnostic criteria and proposes advances to improve the diagnostic framework. On the basis of these refinements, the diagnosis of AD can be simplified, requiring the presence of an appropriate clinical AD phenotype (typical or atypical) and a pathophysiological biomarker consistent with the presence of Alzheimer's pathology. We propose that downstream topographical biomarkers of the disease, such as volumetric MRI and fluorodeoxyglucose PET, might better serve in the measurement and monitoring of the course of disease. This paper also elaborates on the specific diagnostic criteria for atypical forms of AD, for mixed AD, and for the preclinical states of AD.

TL;DR: Ten cases of Creutzfeldt-Jakob disease have been identified in the UK in recent months with a new neuropathological profile that raises the possibility that they are causally linked to BSE.
