OBJECTIVE: Major depressive disorder in older adults (late-life depression; LLD) is frequently associated with cognitive impairment, and some deficits (e.g., executive function) have been associated with a higher level of treatment resistance. However, the cognitive profile of treatment-resistant LLD (TR-LLD) has not been characterized. We hypothesized that patients with TR-LLD would show deficits in cognitive function, especially executive function, and that executive function deficits would predict poorer response to pharmacotherapy.

DESIGN: Secondary analysis of baseline cognitive data from OPTIMUM, a multicenter RCT evaluating pharmacotherapy strategies for TR-LLD.

SETTING: Five outpatient academic medical centers (4 US, 1 Canada).

PARTICIPANTS: About 369 …

Neuroimmune Mechanisms Of Type 2 Inflammation In The Skin And Lung, Masato Tamari, Aaron M Ver Heul

2020-Current year OA Pubs

Type 2 inflammation has a major role in barrier tissues such as the skin and airways and underlies common conditions including atopic dermatitis (AD) and asthma. Cytokines including interleukin 4 (IL-4), IL-5, and IL-13 are key immune signatures of type 2 inflammation and are the targets of multiple specific therapeutics for allergic diseases. Despite shared core immune mechanisms, the distinct structures and functions of the skin and airways lead to unique therapeutic responses. It is increasingly recognized that the nervous system has a major role in sensing and directing inflammatory processes. Indeed, crosstalk between type 2 immune activation and somatosensory …

Two populations of KSHV-infected cells were identified, one of which represented a CD34-negative proliferative fraction of endothelial cells, and the second representing CD34-positive cells expressing endothelial genes found in a variety of cell types including high endothelial venules, fenestrated capillaries, and endothelial tip …

Dynein Light Chains 1 And 2 Are Auxiliary Proteins Of Ph-Sensitive Kir4.1 Channels, Sun-Joo Lee, Jian Gao, Ellen Thompson, Jonathan Mount, Colin G Nichols

2020-Current year OA Pubs

Inward rectifier Kir4.1 potassium channels are abundantly expressed in cells that are important for electrolyte homeostasis. Dysregulation of Kir4.1 underlies various neurological disorders. Here, through biochemical and structural studies of full-length Kir4.1, we show that dynein light chain 1 and 2 proteins, also as known as LC8, copurify with Kir4.1 at stoichiometric levels. Direct interaction between Kir4.1 and LC8 is supported by in vitro binding assays and reiterated with native Kir4.1 proteins from mouse brain. Notably, we identify a LC8 binding motif in the unstructured N terminus of Kir4.1. Among Kir subtypes, the motif is unique to Kir4.1 and is …

Patient Selection, Ventricular Tachycardia Substrate Delineation, And Data Transfer For Stereotactic Arrhythmia Radioablation: A Clinical Consensus Statement Of The European Heart Rhythm Association Of The European Society Of Cardiology And The Heart Rhythm Society, Katja Zeppenfeld, Clifford Robinson, Et Al.

2020-Current year OA Pubs

Stereotactic arrhythmia radioablation (STAR) is a novel, non-invasive, and promising treatment option for ventricular arrhythmias (VAs). It has been applied in highly selected patients mainly as bailout procedure, when (multiple) catheter ablations, together with anti-arrhythmic drugs, were unable to control the VAs. Despite the increasing clinical use, there is still limited knowledge of the acute and long-term response of normal and diseased myocardium to STAR. Acute toxicity appeared to be reasonably low, but potential late adverse effects may be underreported. Among published studies, the provided methodological information is often limited, and patient selection, target volume definition, methods for determination and …

2020-Current year OA Pubs

Neurodegenerative diseases of both the central and peripheral nervous system are characterized by selective neuronal vulnerability, i.e., pathology that affects particular types of neurons. While much of this cell type selectivity may be driven by intrinsic differences among the neuron subpopulations, neuron-extrinsic mechanisms such as the selective malfunction of glial support cells may also play a role. Recently, we identified a population of Schwann cells (SCs) expressing

Mechanical stretch can activate long-lived changes in fibroblasts, increasing their contractility and initiating phenotypic transformations. This activation, critical to wound healing and procedures such as skin grafting, increases with mechanical stimulus for cells cultured in two-dimensional but is highly variable in cells in three-dimensional (3D) tissue. Here, we show that static mechanical stretch of cells in 3D tissues can either increase or decrease fibroblast activation depending upon recursive cell-extracellular matrix (ECM) feedback and demonstrate control of this activation through integrated in vitro and mathematical models. ECM viscoelasticity, signaling dynamics, and cell mechanics combine to yield a predictable, but nonmonotonic, relationship …

Multicilia Dynamically Transduce Sonic Hedgehog Signaling To Regulate Choroid Plexus Functions, Suifang Mao, Michael J Holtzman, Et Al.

2020-Current year OA Pubs

The choroid plexus is a major site for cerebrospinal fluid (CSF) production, characterized by a multiciliated epithelial monolayer that regulates CSF production. We demonstrate that defective choroid plexus ciliogenesis or intraflagellar transport yields neonatal hydrocephalus, at least in part due to increased water channel Aqp1 and ion transporter Atp1a2 expression. We demonstrate choroid plexus multicilia as sensory cilia, transducing both canonical and non-canonical Sonic Hedgehog (Shh) signaling. Interestingly, it is the non-canonical Shh signaling that represses Aqp1 and Atp1a2 expression by the Smoothened (Smo)/Gαi/cyclic AMP (cAMP) pathway. Choroid plexus multicilia exhibit unique ciliary ultrastructure, carrying features of both primary and …
