Virus-free CRISPR knock-in of a chimeric antigen receptor into KLRC1 generates potent GD2-specific natural killer cells.

Natural killer (NK) cells are an appealing off-the-shelf, allogeneic cellular therapy due to their cytotoxic profile. However, their activity against solid tumors remains suboptimal in part due to the upregulation of NK-inhibitory ligands, such as HLA-E, within the tumor microenvironment. Here, we utilize CRISPR-Cas9 to disrupt the KLRC1 gene (encoding the HLA-E-binding NKG2A receptor) and perform non-viral insertion of a GD2-targeting chimeric antigen receptor (CAR) within NK cells isolated from human peripheral blood.

Gender Differences in the Association Between Anxiety and Interoceptive Insight.

Anxiety is one of the most common and debilitating mental health disorders, and is related to changes in interoception (perception of bodily states). While anxiety is more prevalent in women than men, gender differences in interoception-anxiety associations are often overlooked. Here, we examined gender-specific relationships between anxiety and interoception in the breathing domain, utilising multicentre data pooled from four study sites (N = 175; 51% women).

Australia's marine fishes DNA barcode reference library for integrated taxonomy, metabarcoding & eDNA research.

Over 15 000 species of fishes are found globally in the marine environment and DNA barcodes are used extensively to describe, catalogue, understand and manage this diversity. The dataset outlined here represents a DNA barcode reference library of the mitochondrial cytochrome c oxidase subunit 1 gene (COI) from 9767 voucher specimens (representing at least 2220 species and 288 families) of marine fishes. This publicly available dataset in the Barcode of Life Data System (BOLD) represents 17 years (2005-2022) of barcoding of marine fishes identified from Australian territorial waters.

Enabling simultaneous photoluminescence spectroscopy and X-ray footprinting mass spectrometry to study protein conformation and interactions.

X-ray footprinting mass spectrometry (XFMS) is a structural biology method that uses broadband X-rays for hydroxyl radical labeling to map protein interactions and conformation in solution. However, while XFMS alone provides important structural information on biomolecules, as we move into the era of the interactome, hybrid methods are becoming increasingly necessary to gain a comprehensive understanding of protein complexes and interactions. Toward this end, we report the development of the first synergetic application of inline and real-time fluorescent spectroscopy at the Advanced Light Source's XFMS facility to study local protein interactions and global conformational changes simultaneously.

Genetic variants in DDX53 contribute to autism spectrum disorder associated with the Xp22.11 locus.

Autism spectrum disorder (ASD) exhibits an ∼4:1 male-to-female sex bias and is characterized by early-onset impairment of social/communication skills, restricted interests, and stereotyped behaviors. Disruption of the Xp22.11 locus has been associated with ASD in males.

Frontal localisation of a theory-based anxiety disorder biomarker - Goal conflict specific rhythmicity.

Purpose: Anxiety disorders are a major global issue. Diagnosis via symptoms, not biological causes, delivers poor treatment outcomes. Our frontal EEG biomarker, Goal Conflict Specific Rhythmicity (GCSR; 4-12 Hz), developed from our long-standing detailed neuropsychological theory of anxiety processes, is reduced by all chemical types of selective anxiolytic and is high in cases across a range of currently diagnosed anxiety disorders.

Cryo-EM structure of a photosystem I variant containing an unusual plastoquinone derivative in its electron transfer chain.

Photosystem I (PS I) is a light-driven oxidoreductase responsible for converting photons into chemical bond energy. Its application for renewable energy was revolutionized by the creation of the MenB deletion (Δ) variant in the cyanobacterium sp. PCC 6803, in which phylloquinone is replaced by plastoquinone-9 with a low binding affinity.

Key factors related to happiness and anxiety in Aotearoa New Zealand during the COVID-19 pandemic.

Aim: Mental wellbeing has been one of the most prominent health concerns in Aotearoa New Zealand and has only been exacerbated by the COVID-19 pandemic. Here we explored factors associated with anxiety and happiness in a mid-pandemic climate in Aotearoa.

Methods: Analyses were performed on the anxiety and happiness scores from the wellbeing survey in December 2020 (Statistics NZ Tatauranga Aotearoa; 30,000 responders contacted for the Household Labour Force Survey).

Emotional regulation and coping strategies predicted trajectories of anxiety across the first year of the COVID-19 pandemic.

Background: Adverse impacts of the COVID-19 pandemic on mental health have been well-documented, but only a few studies have characterized distinct trajectories of anxiety over time. Further, whether specific emotion regulation and coping efforts to manage pandemic distress predict these distinct trajectories remains unexamined.

Aims: The study characterized anxiety trajectories across the first year of the pandemic and identified emotion regulation and coping strategies that predict these classes of anxiety trajectories.

The PvRBP2b-TfR1 interaction is not essential for reticulocytes invasion by Plasmodium vivax isolates from Cambodia.

Plasmodium vivax is the most widespread of the different Plasmodium species able to infect humans and is responsible for most malaria cases outside Africa. An effective, strain-transcending vaccine that alleviates or suppresses erythrocyte invasion would be a game-changer in eliminating vivax malaria. Recently, the binding of P.

Infrared Spectroscopy of Phase Transitions in the Lowest Landau Levels of Bilayer Graphene.

We perform infrared magnetospectroscopy of Landau level (LL) transitions in dual-gated bilayer graphene. At ν=4 when the zeroth LL (octet) is filled, two resonances are observed indicating the opening of a gap. At ν=0 when the octet is half-filled, multiple resonances disperse nonmonotonically with increasing displacement field, D, perpendicular to the sheet, showing a phase transition at modest displacement fields from a canted antiferromagnet (CAFM) to the layer-polarized state, with a gap that opens linearly in D.

Multi-disciplinary team approach for pediatric hemimegalencephaly: Insights from a single institutional case series.

Recent genetic studies have revealed that hemimegalencephaly (HME) is a multi-system disorder associated with germline or mosaic variants within the PI3K-mTOR-GATOR1 signaling pathways. Patients with HME typically develop drug-resistant epilepsy necessitating extensive evaluation, hemispherectomy, and long-term management. We describe the role of a multidisciplinary team (MDT) for the diagnosis and management of recent patients with HME at UCLA who underwent hemispherectomy.

Differential effects of COVID-19 stressor types on mental health and moderating roles of coping strategies.

Stress exposure often leads to poor mental health, but whether of stressors predict levels of mental health symptoms and whether coping differentially moderates these associations remain untested. This study examined whether COVID-19 stressor types (financial-, activity-, and infection-related) differentially predicted subsequent mental health (general distress, posttraumatic stress symptoms (PTSS), and positive states of mind) and whether different types of coping moderated these relationships. In April, 2020, questionnaires assessing the impact of COVID-19 on daily life were administered to an adult sample across the US ( = 1,546); 861 (55.

FocalPose++: Focal Length and Object Pose Estimation Via Render and Compare.

We introduce FocalPose++, a neural render-and-compare method for jointly estimating the camera-object 6D pose and camera focal length given a single RGB input image depicting a known object. The contributions of this work are threefold. First, we derive a focal length update rule that extends an existing state-of-the-art render-and-compare 6D pose estimator to address the joint estimation task.

Dissecting host-microbe interactions with modern functional genomics.

Interrogation of host-microbe interactions has long been a source of both basic discoveries and benefits to human health.
