A Bi‐Adjuvant Senolytic Nanovaccine Modulating Dendritic Cell Senescence Ameliorates Aging‐Related Metabolic Dysfunction

open access: yesAdvanced Science, EarlyView.
An active biomaterial‐based bi‐adjuvant nanovaccine restores the immunocompetence of aged dendritic cells to overcome senescent cell tolerance. Accompanied by the downregulation of mitotic kinases Aurka/b and attenuation of senescence‐associated PI3K/AKT phosphorylation, the nanovaccine enhances antigen‐presenting capacity and promotes potent cytotoxic

FADS2‐STING Signaling in Sertoli Cells Orchestrates Collagen Deposition and Germ Cell Necroptosis in Idiopathic Non‐Obstructive Azoospermia

open access: yesAdvanced Science, EarlyView.
In Sertoli cells of iNOA testes, downregulation of FADS2 activates STING, promoting collagen deposition and peritubular fibrosis while increasing germ‐cell susceptibility to necroptosis. Supplementation with FADS2‐derived PUFAs (GLA and DHA) inhibits STING, alleviates collagen accumulation, and facilitates the recovery of spermatogenesis.

Early‐Life Polyethylene Microplastic Exposure Exacerbates ADHD‐Like Behaviors in Mice via PI3K/AKT1/Nrf2 Signaling: Evidence From the Pilot Cohort and Multi‐Omics Analyses

open access: yesAdvanced Science, EarlyView.
Circulating polyethylene microplastic burden is positively associated with heightened ADHD symptom severity and systemic redox‐inflammatory imbalance in children. Mechanistic investigation in a developmental co‐exposure mouse model further demonstrates that microplastics aggravate ADHD‐like behaviors, dopaminergic dysregulation, and oxidative ...

Rethinking Cochlear Implants: The Need for Precise Temporal Coding

open access: yesAdvanced Science, EarlyView.
Spatial hearing relies on sensitivity to interaural temporal cues, but this sensitivity is often poorly developed in patients with cochlear implants, particularly those with early‐onset hearing loss. Rats with cochlear implants, however, demonstrate excellent temporal sensitivity, suggesting that this limitation is not inevitable.

CD34+ Progenitors Promote Ageing‐Associated Valve Sclerosis through the PDGFR–JNK–JUNB Pathway

open access: yesAdvanced Science, EarlyView.
In age‐related aortic valve sclerosis, non‐bone marrow CD34+ progenitor valvular interstitial cells (VICs) undergo transdifferentiation into periostin+ myofibroblast‐like VICs via the PDGFR‐JNK‐JUNB axis, driving leaflet thickening and fibrosis. Ablating non‐bone marrow CD34+ cells attenuates this remodeling.

LepR‐Lineage Cells Represent the Main Target of the Nociceptive CGRP Pathway in White Adipose Tissue Browning

open access: yesAdvanced Science, EarlyView.
Regulation of WAT Browning and UCP1 Expression in LepR‐MSCs of Inguinal WAT by Nociceptive CGRP and Sympathetic Nervous System (SNS) Noradrenaline (NE). ABSTRACT Sympathetic innervation regulates white adipose tissue (WAT) browning; however, the roles of nociceptive neurons and their associated target cells remain unknown.

Constructing and Validating New County‐Level Cultural Capital Indices for Applied Policy Analysis: Evidence From SNAP Take‐Up

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Cultural capital influences a wide range of social and economic outcomes, yet quantitative measures suitable for policy analysis remain limited. We develop county‐level cultural capital indices for the US based on Bourdieu's framework of objectified, embodied, and institutionalized cultural capital.
