T-cell immunology of the lung: maintaining the balance between host defence and immune pathology.

Authors:
Daniel M Altmann

Immunology 2019 Jan;156(1):1-2

Department of Medicine, Hammersmith Hospital, London, UK.

Respiratory immunology poses the dual questions of how to grapple with lung infection as one of the greatest unmet global health needs of our time, while also dealing with the growing challenge posed by chronic diseases of excessive or inappropriate lung inflammation and immunity, such as chronic obstructive lung disease and asthma. These separate branches of pulmonary research are linked by the clear observation that, in a tissue as fragile as the lung, protection from microbial attack may come at the cost of chronic inflammatory damage. A number of recent studies have considered specific aspects of this double-edged sword, including the diversity of responses to fungal exposure, sources and consequences of interleukin-17 immunity, and the role of tertiary lymphoid follicles in the lung.

Hot spots for GPCR signaling: lessons from single-molecule microscopy.

Curr Opin Cell Biol 2018 Dec 3;57:57-63. Epub 2018 Dec 3.

Institute of Pharmacology and Bio-Imaging Center, University of Würzburg, Germany.

G protein-coupled receptors (GPCRs) are among the best-studied membrane receptors, mainly due to their central role in human physiology, involvement in disease and relevance as drug targets. Although biochemical and pharmacological studies have characterized the main steps in GPCR signaling, how GPCRs produce highly specific responses in our cells remains insufficiently understood. New developments in single-molecule microscopy have made it possible to study the protein-protein interactions at the basis of GPCR signaling in previously inconceivable detail. Read More

Action co-representation and the sense of agency during a joint Simon task: Comparing human and machine co-agents.

Conscious Cogn 2018 Dec 3;67:44-55. Epub 2018 Dec 3.

ONERA, The French Aerospace Lab, Département Traitement de l'Information et Systèmes, Salon-de-Provence, France.

Recent studies have suggested that individuals are not able to develop a sense of joint agency during joint actions with artificial systems. We sought to examine whether this lack of joint agency is linked to individuals' inability to co-represent the machine-generated actions. Fifteen participants observed or performed a Simon response time task either individually, or jointly with another human or a computer. Read More

Body composition and sarcopenia: the next-generation of personalized oncology and pharmacology?

Pharmacol Ther 2018 Dec 3. Epub 2018 Dec 3.

Department of Medical Oncology, CAncer Research for PErsonalized Medicine (CARPEM), Paris Centre Teaching Hospitals, Paris Descartes University, USPC, Paris, France.

Body composition has gained increasing attention in oncology in recent years due to fact that sarcopenia has been revealed to be a strong prognostic indicator for survival across multiple stages and cancer types and a predictive factor for toxicity and surgery complications. Accumulating evidence over the last decade has unraveled the "pharmacology" of sarcopenia. Lean body mass may be more relevant to define drug dosing than the "classical" body surface area or flat-fixed dosing in patients with cancer. Read More

NEW INSIGHTS ON THE REGULATION OF CANCER CACHEXIA BY N-3 POLYUNSATURATED FATTY ACIDS.

Pharmacol Ther 2018 Dec 3. Epub 2018 Dec 3.

Institute of Physical Activity Sciences and Sports, Cruzeiro do Sul University, Sao Paulo, Brazil,; Institute of Biomedical Sciences, University of Sao Paulo, Sao Paulo, Brazil;. Electronic address:

Cancer cachexia is a multifactorial syndrome that develops during malignant tumor growth. Changes in plasma levels of several hormones and inflammatory factors result in an intense catabolic state, decreased activity of anabolic pathways, anorexia, and marked weight loss, leading to cachexia development and/or accentuation. Inflammatory mediators appear to be related to the control of a highly regulated process of muscle protein degradation that accelerates the process of cachexia. Read More

Department of Microbiology and Immunology, University of Rochester Medical Center, United States. Electronic address:

Owing to the high incidence of multi-drug resistance and challenges posed by the complex and long duration of treatments, Mycobacterium tuberculosis (Mtb) infections remain a significant clinical burden, which would benefit from development of novel immuno-therapeutic-based treatment strategies. Among early immune effectors, invariant or innate-like (i)T cells are attracting attention because of their potential regulatory activity, which can shape anti-mycobacterial immune responses. Unlike conventional T cells, iT cells express a semi-invariant T cell receptor, and respond rapidly and robustly to molecular patterns presented by MHC class I-like molecules. Read More

Gastroenterology 2018 Dec 3. Epub 2018 Dec 3.

Department of Epidemiology and Center for Gastrointestinal Biology and Disease, University of North Carolina at Chapel Hill, Chapel Hill, NC.

Background & Aims: Increasing rates of young-onset colorectal cancer (CRC) have attracted substantial research and media attention, but we know little about racial disparities among younger adults with CRC. We examined racial disparities in young-onset CRC by comparing CRC incidence and relative survival among younger (age <50 years) adults, in 2 time periods.

Methods: Using data from the Surveillance, Epidemiology, and End Results program of cancer registries, we estimated CRC incidence rates (per 100,000 persons ages 20 - 54 years) from 1992 through 2014, for different time periods (1992-1996 vs 2010-2014) and races (white vs black). Read More

Acute effects of zinc and insulin on arcuate anorexigenic Proopiomelanocortin (POMC) neurons.

Br J Pharmacol 2018 Dec 6. Epub 2018 Dec 6.

Division of Hypothalamic Research, the University of Texas Southwestern Medical Center at Dallas, Dallas, Texas, USA.

Background And Purpose: Acute insulin administration results in a hyperpolarization and concomitant decrease of firing rate in a subpopulation of arcuate Proopiomelanocortin (POMC) and Neuropeptide Y/Agouti-related peptide (NPY/AgRP) cells. This rapid effect on cellular activity has been implicated as a cellular correlate of insulin effects on energy balance and glucose homeostasis. Recent evidence suggests that zinc in mammalian insulin formulations is required for the insulin-induced inhibition of arcuate POMC neurons, while guinea-pig insulin, which fails to bind zinc, activates POMC neurons in mice.

Norwich Medical School, University of East Anglia, Norwich Research Park, Norwich, Norfolk, UK, NR4 7TJ.

Background: Researchers have suggested that omega-3 polyunsaturated fatty acids from oily fish (long-chain omega-3 (LCn3), including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)), as well as from plants (alpha-linolenic acid (ALA)) benefit cardiovascular health. Guidelines recommend increasing omega-3-rich foods, and sometimes supplementation, but recent trials have not confirmed this.

Objectives: To assess effects of increased intake of fish- and plant-based omega-3 for all-cause mortality, cardiovascular (CVD) events, adiposity and lipids. Read More

Agentic appeals increase charitable giving in an affluent sample of donors.

PLoS One 2018 6;13(12):e0208392. Epub 2018 Dec 6.

Department of Psychology, University of British Columbia, Vancouver, British Columbia, Canada.

Recent research suggests that affluent individuals adopt agentic self-concepts, striving to stand out from others and to master the environment on their own. The present study provides a road test of this idea, showing that this theorizing can be utilized to increase charitable giving among the affluent, when individuals do not realize that their behavior is being studied. In a naturalistic field experiment conducted as part of an annual fundraising campaign (N = 12,316), we randomly assigned individuals from an affluent sample to view messages focused on agency (vs. Read More

Spectral clustering with distinction and consensus learning on multiple views data.

PLoS One 2018 6;13(12):e0208494. Epub 2018 Dec 6.

School of Computer and Information Technology, Shanxi University, Taiyuan, China.

Since multi-view data are available in many real-world clustering problems, multi-view clustering has received considerable attention in recent years. Most existing multi-view clustering methods learn consensus clustering results but do not make full use of the distinct knowledge in each view so that they cannot well guarantee the complementarity across different views. In this paper, we propose a Distinction based Consensus Spectral Clustering (DCSC), which not only learns a consensus result of clustering, but also explicitly captures the distinct variance of each view.

INSERM, CNRS, UNIV Nantes, l'institut du thorax, Nantes, France.

Population stratification is a well-known confounding factor in both common and rare variant association analyses. Rare variants tend to be more geographically clustered than common variants, because of their more recent origin. However, it is not yet clear if population stratification at a very fine scale (neighboring administrative regions within a country) would lead to statistical bias in rare variant analyses.

Temporal changes in the viromes of Swedish Varroa-resistant and Varroa-susceptible honeybee populations.

PLoS One 2018 6;13(12):e0206938. Epub 2018 Dec 6.

Department of Ecology, Swedish University of Agricultural Sciences, Uppsala, Sweden.

The parasitic mite, Varroa destructor, in combination with the viruses it vectors, is the main cause for global colony losses of the European honeybee, Apis mellifera. However, an isolated honeybee population established in 1999 on the Island of Gotland, Sweden has naturally acquired resistance to the mite, and has survived without mite control treatment for more than 18 years. A recent study has shown that this mite resistant (MR) population also appears to be resistant to Black queen cell virus (BQCV) and Sacbrood virus (SBV) and tolerant to Deformed wing virus (DWV), relative to nearby mite susceptible (MS) honeybee populations.

Transverse and longitudinal spin-fluctuations in INVAR FeNi.

J Phys Condens Matter 2019 Jan;31(2):025802

ISIS Neutron and Muon Facility, Science and Technology Facilities Council, Rutherford Appleton Laboratory, Didcot, OX11 0QX, United Kingdom.

The presence of spin-fluctuations deep within the ordered state of ferromagnetic [Formula: see text] alloy [Formula: see text] has long been suspected but seldom directly observed. Inhomogeneities of one type or another have been cited as important in stabilizing [Formula: see text] behaviour-either longitudinal spin-fluctuations associated with the [Formula: see text]-state (local environment) model or transverse magnetisation arising from non-collinear spin structures. In this study we employ small-angle neutron scattering with neutron polarization analysis to distinguish between the two possibilities. Read More

Titin as a force generating muscle protein under regulatory control.

J Appl Physiol (1985) 2018 Dec 6. Epub 2018 Dec 6.

Institute of Physiology II, University of Muenster, Germany.

Titin has long been recognized as a mechanical protein in muscle cells that has a main function as a molecular spring in the contractile units, the sarcomeres. Recent work suggests that the titin spring contributes to muscle contraction in a more active manner than previously thought. In this review, we highlight this property, specifically the ability of the immunoglobulin-like (Ig) domains of titin to undergo unfolding-refolding transitions when isolated titin molecules or skeletal myofibrils are held at physiological force levels.

The effect of net gas volume changes on alveolar and arterial gas partial pressures in the presence of ventilation-perfusion mismatch.

J Appl Physiol (1985) 2018 Dec 6. Epub 2018 Dec 6.

Department of Anaesthesia, Austin Hospital, Australia.

The second gas effect (SGE) occurs when nitrous oxide enhances the uptake of volatile anesthetics administered simultaneously. Recent work shows that the SGE is greater in blood than in the gas phase, that this is due to ventilation-perfusion mismatch, that as mismatch increases, the SGE increases in blood but is diminished in the gas phase, and that these effects persist well into the period of nitrous oxide maintenance anesthesia. These modifications of the SGE are most pronounced with the low soluble agents in current use. Read More

Insight into the perioperative management of direct oral anticoagulants: concerns and considerations.

Expert Opin Pharmacother 2018 Dec 6:1-8. Epub 2018 Dec 6.

d Division of Cardiology, Department of Medicine and Therapeutics , The Chinese University of Hong Kong, Prince of Wales Hospital , Hong Kong , China.

Introduction: Direct oral anticoagulants (DOACs) have gained momentum in recent years in patients requiring anticoagulation for the prevention and management of venous thromboembolism and thromboembolic events caused by atrial fibrillation. The use of these agents involves potential bleeding complications, particularly during invasive procedures. With increasing use of DOACs, adequate knowledge regarding the perioperative management of patients on DOACs has become indispensable. Read More

Residual Normality Assumption and the Estimation of Multiple Membership Random Effects Models.

Multivariate Behav Res 2018 Dec 6:1-16. Epub 2018 Dec 6.

a Department of Educational Policy Studies , Georgia State University.

While conventional hierarchical linear modeling is applicable to purely hierarchical data, a multiple membership random effects model (MMrem) is appropriate for nonpurely nested data wherein some lower-level units manifest mobility across higher-level units. Although a few recent studies have investigated the influence of cluster-level residual nonnormality on hierarchical linear modeling estimation for purely hierarchical data, no research has examined the statistical performance of an MMrem given residual non-normality. The purpose of the present study was to extend prior research on the influence of residual non-normality from purely nested data structures to multiple membership data structures. Read More

Nordic homecare nursing from the perspective of homecare nurses-a meta-ethnography.

Br J Community Nurs 2018 Dec;23(12):597-604

Associate professor, Study director, Aarhus University, Department of Public Health, Denmark.

The pressure on homecare nursing in the Nordic countries has increased in recent years because of a reorganisation of healthcare systems that has put a focus on very early discharge from hospital as well as demographic changes. This article details an analysis of the findings of 13 published qualitative research reports about Nordic homecare nurses' experiences of their work. Using a process of meta-ethnography, the authors identify five themes within the primary research: home care as a professional practice on foreign ground; home care as a massive time constraint; home care as fair rationing; home care as relationships with relatives as fellow players or opponents; and home care as latent paternalism.
