We are pleased to share with you the 25 most downloaded Nature Communications articles* in health sciences published in 2023. (Please note we have a separate collection for the Top 25 COVID-19 papers.) Featuring authors from around the world, these papers highlight valuable research from an international community.
The relation between daily meal and fasting timing with cardiovascular disease incidence remains unclear. Here, authors show that a later daily meal timing is associated with increased cardiovascular disease risk, especially in women. This study suggests that adopting earlier daily eating patterns may be beneficial for cardiovascular prevention.
Half of all pregnancies are unintended; thus, existing family planning options are inadequate. This proof-of-concept study validates an on-demand contraception strategy for men, showing high effectiveness in quickly and temporarily reducing male fertility in mice.
Serotonin 5-HT2A receptor signaling mechanisms associated with predicting psychedelic potential remain elusive. Using 5-HT2A-selective β-arrestin-biased ligands, here the authors show that a threshold level of 5-HT2A-Gq efficacy and not β-arrestin recruitment is associated with psychedelic potential.
In this study, the authors introduce the concept of a unique cellular subtype within the organic stroma, which does not conform to a typical young or senescent but is significantly associated with age-related organic dysfunction among the elderly.
The use of biomaterial scaffolds-based cartilage grafts could potentially innovate the Osteoarthritis (OA) treatment, but has been limited by toxicity concerns and invasive surgical procedures. Here, the authors report an injectable and biodegradable piezoelectric hydrogel with ultrasound activation to offer a minimally invasive approach for OA treatment.
The gut microbiome is causally linked to body weight in preclinical models. Here, in a controlled feeding study, the authors show that greater delivery of gut-microbiome fermentable dietary substrates to the colon leads to a net negative energy balance that is accompanied by robust microbial and host responses.
The memory function of sleep relies on the coordination of slow oscillations and spindles. Here the authors show that respiration is associated with the emergence and interplay of these sleep rhythms, and that this coupling is linked to memory reactivation.
Here, using participants in the CHILD birth cohort, the authors reveal that impaired 1-year microbiota maturation may be universal to 5-year pediatric allergies, mediated by functional and metabolic imbalances of compromised mucous integrity, elevated oxidative activity, decreased fermentation, and elevated trace amines.
Exercise has positive effects on the brain during aging. Here the authors show that in mice, platelet-released exerkine PF4 mediates the effects of exercise on the brain.
Large genes require dual adeno-associated viral (AAV) vectors for in vivo delivery/expression, but current methods have limitations. Here the authors develop and functionally evaluate REVeRT, an efficient and flexible dual AAV vector technology based on reconstitution via mRNA trans-splicing.
The treatment of diabetic wounds tends to be hindered by complex wound environments, and the critical role of the microenvironment in the chronic diabetic wounds has not been explored for therapeutic development. Here, the authors develop a wound microenvironment-responsive microneedle bandage to achieve self-enhanced, catabolic and dynamic therapy of chronic wounds.
Achieving successful in vivo cartilage regeneration remains challenging. Here they present a cell-free, multiple hydrogen-bond crosslinked hydrogel loaded with tannic acid and Kartogenin with ultra-durable mechanical properties and stage-dependent drug release behavior to promote cartilage regeneration.
Cancer-associated fibroblasts (CAFs) can produce ECM and form a physical barrier around the tumour. Here, the authors show in transgenic mouse models and in vitro systems that CAFs are able to actively compress cancer cells using actomyosin contractility and this leads to a modulation of cancer cell mechanosensing and tumour reorganisation.
Using integrative multi-omics and CRISPR knock-out of all ~1,900 transcription factors, the authors identify essential transcription factors required for Neurogenin-driven differentiation of human cortical neurons.
Knowledge on how the gut microbiome and resistome responds to antibiotics across age remains limited. Here, using metagenomics data from Danish infants and young adults, the authors show that antibiotics have a more lasting impact on adults compared to infants.
Targetable delivery vectors for genetic cargo are needed. Here the authors report a modular platform with separate fusion and targeting components—Delivery to Intended REcipient Cells Through Envelope Design (DIRECTED)—and show cell type-specific delivery.
Targeting gluten antigens presents a plausible therapy option for celiac disease. Here the authors generate and characterize a broadly neutralizing antibody recognizing more than 25 gluten peptide:HLA-DQ2.5 complexes, with structural analyses implicating its mode of interaction, and with mouse in vivo studies supporting its therapeutic feasibility.
There is currently no specific antidote for death cap mushroom poisoning treatment. Here, the authors identify STT3B as a druggable target and show that indocyanine green is a STT3B inhibitor that can block α-amanitin toxicity in cell lines, liver organoids and mice.
There is a growing interest in the role of timing of physical activity (PA) in improving health. Here, using a large-scale cohort study, the authors show that moderate-to-vigorous PA at the optimal time of day robustly predicts lower mortality risk and may maximize the beneficial effect of PA.
How aging affects the brain active milieu remains unknown. Here, the authors reveal atrophy and mitochondrial malfunction of astrocytes but not neurons in older human neocortex.
The cells of our bodies use chemical signals to talk with each other. Here the authors describe a class of signaling molecules called “capped peptides” that may mediate cell-cell communication. Unlike other peptides, capped peptides have unique chemical modifications which make them potentially more active and stable.
Difficulties can be encountered when translating research between cells from animals and humans because of gene expression differences. Here the authors perform an integrative transcriptomic analysis from human and mouse neutrophils and identify a core inflammation program shared across inflamed contexts.
Interpreting untargeted mass spectrometry (MS) data is challenging due to incomplete reference libraries. Here, the authors created the nearest neighbor suspect spectral library from largescale public MS data, significantly enhancing the ability to hypothesize structures for unknown mass spectra.
PSC-brain organoids are typically formed by static medium switches. Here, authors show that a temporal morphogen gradient during neural induction allows the formation of well-specified cortical organoids with a self-organized single neuroepithelium.
Previous work has shown speech decoding in the human brain for the development of neural speech prostheses. Here the authors show that high density µECoG electrodes can record at micro-scale spatial resolution to improve neural speech decoding.
