Cohesin-mediated NF-κB signaling limits hematopoietic stem cell self-renewal in aging and inflammation.

J Exp Med 2018 Dec 7. Epub 2018 Dec 7.

Leibniz Institute on Aging, Fritz Lipmann Institute (FLI), Jena, Germany

Organism aging is characterized by increased inflammation and decreased stem cell function, yet the relationship between these factors remains incompletely understood. This study shows that aged hematopoietic stem and progenitor cells (HSPCs) exhibit increased ground-stage NF-κB activity, which enhances their responsiveness to undergo differentiation and loss of self-renewal in response to inflammation. The study identifies /cohesin as a critical mediator of NF-κB signaling, which increases chromatin accessibility in the vicinity of NF-κB target genes in response to inflammation. Read More

A test of dopamine hyper- and hyposensitivity in alcohol use.

Addict Behav 2018 Dec 4;90:395-401. Epub 2018 Dec 4.

Department of Psychology, University of South Florida, 4202 East Fowler Ave, PCD 4118G, Tampa, FL 33620, United States.

Biases in outcome processing, mediated by the mesocortical dopaminergic (DA) system, may predict individual differences in the frequency and quantity of alcohol use. We tested the hypothesis that genetic markers associated with increased DA neurotransmission contribute to reduced neural sensitivity to costs and increased alcohol use in an undergraduate sample. We created a DA transmission score using five genetic markers related to DA transmission and assessed neural sensitivity to cost using the feedback-related negativity (FRN), an event-related potential implicated in neural outcome evaluation, on both passive evaluative and active decision-making tasks.

Predictors of stent thrombosis and their implications for clinical practice.

Nat Rev Cardiol 2018 Dec 5. Epub 2018 Dec 5.

Kardiologie I, Zentrum für Kardiologie, University Medical Center Mainz and DZHK Standort Rhein-Main, Mainz, Germany.

Stent thrombosis (ST) is a rare but severe complication of coronary procedures with high mortality, high relapse rate and a very complex pathophysiology. An individual's susceptibility to ST is multifactorial and results from interactions between clinical factors, endothelial biology, hypersensitivity and/or inflammatory reactions, blood rheology, platelet reactivity, clotting factors, physical and mechanical properties of the stent and from the effects of these different factors on the fluid dynamics of blood flow. Since the introduction of stents 32 years ago, continuous improvements in our understanding of the pathophysiology of ST have triggered important advances, including new therapies, new technologies and an increased awareness of the implications of implantation techniques.

Rapid, precise diagnosis of Epstein-Barr virus-associated T lymphocyte or natural killer cell lymphoproliferative diseases is clinically important to prevent disease progression and avoid fatal outcomes for patients. In addition to detecting increased copy numbers of Epstein-Barr virus, identification of the lymphocyte subpopulation targeted by the virus infection is crucial to reaching the final diagnosis. However, these procedures are laborious and require large amounts of sample. Read More

Epidermotropism in Nodular Secondary Syphilis.

Indian J Dermatol 2018 Nov-Dec;63(6):509-511

Department of Dermatology, Consorcio Hospital General Universitario de Valencia, Valencia, Spain.

Nodular secondary syphilis results from the hematogenous and lymphatic dissemination of spirochetes. Clinically, the lesions appear as partially infiltrated plaques or red-violaceous nodules, which can be solitary or multiple. Several hypotheses have been put forward to explain the formation of these infiltrated or granulomatous lesions. Read More

D1 receptor hypersensitivity in mice with low striatal D2 receptors facilitates select cocaine behaviors.

Neuropsychopharmacology 2018 Dec 1. Epub 2018 Dec 1.

Laboratory on the Neurobiology of Compulsive Behaviors, National Institute on Alcohol Abuse and Alcoholism, Intramural Research Program, NIH, Bethesda, MD, USA.

Vulnerability for cocaine abuse in humans is associated with low dopamine D2 receptor (D2R) availability in the striatum. The mechanisms driving this vulnerability are poorly understood. In this study, we found that downregulating D2R expression selectively in striatal indirect-pathway neurons triggers a multitude of changes in D1 receptors (D1R)-expressing direct-pathway neurons, which comprise the other main subpopulation of striatal projection neurons.

Enhancement of mouse contact hypersensitivity appears with a short chain triacylglycerol but not with a long chain one.

Toxicology 2018 Nov 29;412:48-54. Epub 2018 Nov 29.

Laboratory of Microbiology and Immunology, School of Pharmaceutical Sciences, University of Shizuoka, 52-1 Yada, Suruga-ku, Shizuoka City, Shizuoka, 422-8526, Japan. Electronic address:

The prevalence of skin allergies could be partly due to the increased exposure to chemicals from consumer products. Chemicals that can enhance hypersensitivity caused by other chemicals are the focus of this study. We have demonstrated that phthalate esters with short chain alcohols enhance fluorescein isothiocyanate (FITC)-induced contact hypersensitivity (CHS) in a mouse model. Read More

Impact of soymilk consumption on 2,4-dinitrofluorobenzene-induced contact hypersensitivity and gut microbiota in mice.

Int J Food Sci Nutr 2018 Dec 2:1-6. Epub 2018 Dec 2.

d Fuji Oil Holdings Inc , Research Institute for Creating Future , Izumisano , Osaka , Japan.

Soymilk is rich in phytochemicals such as soy isoflavones (SIs) and soyasaponins (SSs). Dietary SIs and SSs display inhibitory effects on contact hypersensitivity (CHS), which was reported in a mouse model for allergic contact dermatitis (ACD); however, the beneficial effects of soymilk consumption on CHS remain unknown. Here, we studied the effects of drinking soymilk on CHS and gut microbiota. Read More
