Roles of Ventromedial Prefrontal Cortex and Anterior Cingulate in Subjective Valuation of Prospective Effort.

Cereb Cortex 2018 Dec 12. Epub 2018 Dec 12.

Department of Biomedical Engineering, Johns Hopkins School of Medicine, 773 North Broadway, Baltimore, MD, USA.

The perceived effort level of an action shapes everyday decisions. Despite the importance of these perceptions for decision-making, the behavioral and neural representations of the subjective cost of effort are not well understood. While a number of studies have implicated anterior cingulate cortex (ACC) in decisions about effort/reward trade-offs, none have experimentally isolated effort valuation from reward and choice difficulty, a function that is commonly ascribed to this region.

The Na+/H+ Exchanger Nhe1 Modulates Network Excitability via GABA Release.

Cereb Cortex 2018 Dec 12. Epub 2018 Dec 12.

Institute of Human Genetics, Jena University Hospital, Jena, Germany.

Brain functions are extremely sensitive to pH changes because of the pH-dependence of proteins involved in neuronal excitability and synaptic transmission. Here, we show that the Na+/H+ exchanger Nhe1, which uses the Na+ gradient to extrude H+, is expressed at both inhibitory and excitatory presynapses. We disrupted Nhe1 specifically in mice either in Emx1-positive glutamatergic neurons or in parvalbumin-positive cells, mainly GABAergic interneurons. Read More

Importin α5 Regulates Anxiety through MeCP2 and Sphingosine Kinase 1.

Cell Rep 2018 Dec;25(11):3169-3179.e7

Department of Biomolecular Sciences, Weizmann Institute of Science, Rehovot 76100, Israel. Electronic address:

Importins mediate transport from synapse to soma and from cytoplasm to nucleus, suggesting that perturbation of importin-dependent pathways should have significant neuronal consequences. A behavioral screen on five importin α knockout lines revealed that reduced expression of importin α5 (KPNA1) in hippocampal neurons specifically decreases anxiety in mice. Re-expression of importin α5 in ventral hippocampus of knockout animals increased anxiety behaviors to wild-type levels. Read More

Cell Rep 2018 Dec;25(11):3123-3135.e6

National Institute for Communicable Diseases of the National Health Laboratory Service, Johannesburg 2131, South Africa; Faculty of Health Sciences, University of the Witwatersrand, Johannesburg 2000, South Africa; Centre for the AIDS Programme of Research in South Africa (CAPRISA), University of KwaZulu Natal, Durban 4041, South Africa. Electronic address:

Antibodies that bind residue K169 in the V2 region of the HIV-1 envelope correlated with reduced risk of infection in the RV144 vaccine trial but were restricted to two ED-motif-encoding light chain genes. Here, we identify an HIV-infected donor with high-titer V2 peptide-binding antibodies and isolate two antibody lineages (CAP228-16H/19F and CAP228-3D) that mediate potent antibody-dependent cell-mediated cytotoxicity (ADCC). Both lineages use the IGHV5-51 heavy chain germline gene, similar to the RV144 antibody CH58, but one lineage (CAP228-16H/19F) uses a light chain without the ED motif. Read More

Orphan Receptor GPR88 as an Emerging Neurotherapeutic Target.

ACS Chem Neurosci 2018 Dec 12. Epub 2018 Dec 12.

While G protein-coupled receptors (GPCRs) are recognized as pivotal drug targets involved in multiple physiological and pathological processes, the majority of GPCRs including orphan GPCRs (oGPCRs) are unexploited. GPR88, a brain-specific oGPCR with particularly robust expression in the striatum, regulates diverse brain and behavioral functions including cognition, mood, movement control and reward-based learning, and is thus emerging as a novel drug target for CNS disorders including schizophrenia, Parkinson's disease, anxiety and addiction. Nevertheless, no effective GPR88 synthetic ligands have yet entered into clinical trials and GPR88 endogenous ligands remain unknown. Read More

Age threshold for recommending higher protein intake to prevent age-related muscle weakness: A cross-sectional study in Japan.

PLoS One 2018 12;13(12):e0208169. Epub 2018 Dec 12.

Departments of Health and Social Behavior, School of Public Health, The University of Tokyo, Bunkyo-ku, Tokyo, Japan.

Although insufficient dietary protein intake is a known risk factor for age-related muscle weakness, the optimal age at which higher protein intake is required to prevent muscle weakness is yet to be determined. Using a population-based panel survey of community-dwelling people aged 50-75 years, this cross-sectional study aimed to find the age threshold at which a higher protein intake is associated with higher muscle strength. We utilized a dataset from the Japanese Study of Aging and Retirement conducted between 2007 and 2011. Read More

A transient DMSO treatment increases the differentiation potential of human pluripotent stem cells through the Rb family.

PLoS One 2018 12;13(12):e0208110. Epub 2018 Dec 12.

Department of Psychiatry and Behavioral Sciences, Stanford University School of Medicine, Stanford, California, United States of America.

The propensity for differentiation varies substantially across human pluripotent stem cell (hPSC) lines, greatly restricting the use of hPSCs for cell replacement therapy or disease modeling. Here, we investigate the underlying mechanisms and demonstrate that activation of the retinoblastoma (Rb) pathway in a transient manner is important for differentiation. In prior work, we demonstrated that pre-treating hPSCs with dimethylsulfoxide (DMSO) before directed differentiation enhanced differentiation potential across all three germ layers. Read More

Use of RFID technology to characterize feeder visitations and contact network of hummingbirds in urban habitats.

PLoS One 2018 12;13(12):e0208057. Epub 2018 Dec 12.

Department of Medicine and Epidemiology, School of Veterinary Medicine, University of California Davis, Davis, California, United States of America.

Despite the popular use of hummingbird feeders, there are limited studies evaluating the effects of congregation, sharing food resources and increased contact when hummingbirds visit feeders in urban landscapes. To evaluate behavioral interactions occurring at feeders, we tagged 230 individuals of two species, Anna's and Allen's Hummingbirds, with passive integrated transponder tags and recorded their visits with RFID transceivers at feeders. For detecting the presence of tagged birds, we developed an RFID equipped feeding station using a commercially available antenna and RFID transceiver. Read More

Evidence for encounter-conditional, area-restricted search in a preliminary study of Colombian blowgun hunters.

PLoS One 2018 12;13(12):e0207633. Epub 2018 Dec 12.

University of California Davis, Department of Anthropology, Davis, CA, United States of America.

Active search for prey is energetically costly, so understanding how foragers optimize search has been central to foraging theory. Some theoretical work has suggested that foragers of randomly distributed prey should search using Lévy flights, while work on area-restricted and intermittent search strategies has demonstrated that foragers can use the information provided by prey encounters to more effectively adapt search direction and velocity. Previous empirical comparisons of these search modes have tended to rely on distribution-level analyses, due to the difficulty of collecting event-level data on encounters linked to the GPS tracks of foragers.
