Bingyu Liu, Chengjiang Gao
RLRs (including RIG-I and MDA5) are the main receptors that recognize cytoplasmic viral RNA. Upon binding of viral RNA, RIG-I and MDA5 recruit mitochondria-localized MAVS to activate the downstream antiviral signaling. MAVS forms prion-like aggregates on the mitochondria after virus infection. The regulatory mechanisms for MAVS activation have been defined in various studies. Here, we summarize the recent advances about MAVS roles in antiviral immunity, discuss the regulation of MAVS activation, and suggest interesting areas for future research...

REVIEW
Maximilian J Wessel, Friedhelm C Hummel
Non-invasive brain stimulation (NIBS) combined with behavioral training is a promising strategy to augment recovery after stroke. Current research efforts have been mainly focusing on primary motor cortex (M1) stimulation. However, the translation from proof-of-principle to clinical applications is not yet satisfactory. Possible reasons are the heterogeneous properties of stroke, generalization of the stimulation protocols, and hence the lack of patient stratification. One strategy to overcome these limitations could be the evaluation of alternative stimulation targets, like the cerebellum...

Liquid chromatography-selected reaction monitoring (LC-SRM) mass spectrometry has developed into a versatile tool for quantification of proteins with a wide range of applications in basic science, translational research, and clinical patient assessment. This strategy uniquely complements traditional pathology approaches, like hematoxylin and eosin (H&E) staining and immunohistochemistry (IHC). The multiplexing capabilities offered by mass spectrometry are currently unmatched by other techniques. However, quantification of biomarkers in tissue specimens without the other data obtained from H&E-stained slides or IHC, including tumor cellularity or percentage of positively stained cells inter alia, may not provide as much information that is needed to fully understand tumor biology or properly assess the patient...

Appearance of L-DOPA-induced dyskinesia (LID) represents a major limitation in the pharmacological therapy with the dopamine precursor L-DOPA. Indeed, the vast majority of parkinsonian patients develop dyskinesia within 9-10 years of L-DOPA oral administration. This makes the discovery of new therapeutic strategies an important need. In the last decades, several animal models of Parkinson's disease (PD) have been developed, to both study mechanisms underlying PD pathology and treatment-induced side effects (i...

BACKGROUND: Chronic pain in childhood is increasingly being recognized as a significant clinical problem for children and their families. Previous research has identified that families want information about the causes of their child's chronic pain, treatment options, and effective strategies to help their child cope with the pain. Unfortunately, parents have reported that finding this information can be challenging. OBJECTIVE: The aim of this study was to actively work together with children attending a pediatric chronic pain clinic and their parents to develop, refine, and evaluate the usability of an art and narrative-based electronic book (e-book) for pediatric chronic pain...

Argonaute (AGO) protein family is highly conserved in eukaryotes and prokaryotes, reflecting its evolutionarily indispensible role in maintaining normal life cycle of the organisms. Small RNA-guided, AGO-dependent RNA interference (RNAi) is a well-studied pathway for gene expression regulation, which can be performed at transcriptional, posttranscriptional or translational level. In addition to RNAi, growing pieces of evidence point to a novel role of AGOs in pre-mRNA (messenger RNA precursor) splicing in animals...

There are many diseases and biological processes that involve circulating cells in the bloodstream, such as cancer metastasis, immunology, reproductive medicine, and stem cell therapies. This has driven significant interest in new technologies for the study of circulating cells in small animal research models and clinically. Most currently used methods require drawing and enriching blood samples from the body, but these suffer from a number of limitations. In contrast, 'in vivo flow cytometry' (IVFC) refers to set of technologies that allow study of cells directly in the bloodstream of the organism in vivo...

ISSUE: Research in education, including health professions education, has long struggled with the competing concerns of academic and practice-based stakeholders. Inspired partially by the work of Stokes and other theorists in science and technology studies, we propose that discussions about compelling research in health professions education might be usefully advanced by considering what it would mean if the community framed itself as a knowledge-producing field instead of aligning itself with either disciplinary or practical interests...

The paper, by translating the concept and the two models of endophenotype (EP), strengthens the hypothesis that there exists a linkage between anorexia nervosa (AN) and autism spectrum disorder (ASD). Specifically, the paper synthesizes empirical research that supported the idea that individuals with AN and individuals with ASD share similarities with respect to their neurocognitive EPs and temperament EPs. The paper then introduces an innovative structure to emphasize the subtle difference between neurocognitive EPs and temperament EPs in relation to AN and ASD...

REVIEW
Romain Madelaine, Philippe Mourrain
In humans, optic nerve injuries and associated neurodegenerative diseases are often followed by permanent vision loss. Consequently, an important challenge is to develop safe and effective methods to replace retinal neurons and thereby restore neuronal functions and vision. Identifying cellular and molecular mechanisms allowing to replace damaged neurons is a major goal for basic and translational research in regenerative medicine. Contrary to mammals, the zebrafish has the capacity to fully regenerate entire parts of the nervous system, including retina...

Preterm birth is a major factor which induces neurological and motor impairments, particularly cerebral palsy, in high-risk infants. Early identification of potential neurodevelopmental impairments provides the opportunity to improve neurodevelopmental outcomes in preterm infants through early rehabilitation interventions. Clinically, the general movement assessment is a pivotal tool to predict neurodevelopmental outcomes, especially motor developmental outcomes, in high-risk infants. Movement recognition can continuously capture relevant limb movements and perform objective and quantitative assessment using computerized approaches...
