Immune Checkpoint PD‐L1 Modulates Retinal Microglial Activation to Alleviate Vascular Leakage in Choroidal Neovascularization via ERK

open access: yesAdvanced Science, EarlyView.
PD‐L1 limits neuroinflammation in neovascular AMD by modulating microglial activation. Its deficiency exacerbates vascular leakage and choroidal neovascularization (CNV) via ERK signaling, while enhancing PD‐L1 reduces inflammation and neovascularization. Targeting PD‐L1 may offer a novel immunomodulatory strategy for NVAMD.

FUS Selectively Facilitates circRNAs Packing into Small Extracellular Vesicles within Hypoxia Neuron

open access: yesAdvanced Science, EarlyView.
This study aimed to unravel the role of FUS in the loading of functional circRNAs into neuronal sEVs under hypoxic conditions, which involves their aggregations in SGs and specific interaction between the FUS Zf_RanBP domain to regulate circRNA sorting in sEVs.

Self‐Adjusting Engineered Probiotic for Targeted Tumor Colonization and Local Therapeutics Delivery

open access: yesAdvanced Science, EarlyView.
Zou et al. developed an engineered strain of Escherichia coli Nissle 1917 with precise targeting abilities for colonization and on‐demand payload release. The engineered probiotic survives and embolizes tumors only in the presence of more than 5 mM L‐lactate. Furthermore, the introduction of an α‐hemolysin circuit enhances its anti‐tumor effect.

Bilirubin Targeting WNK1 to Alleviate NLRP3‐Mediated Neuroinflammation

open access: yesAdvanced Science, EarlyView.
At physiological concentrations, bilirubin binds to the kinase domain of WNK1, thereby augmenting its activity and facilitating the phosphorylation of downstream SPAK/OSR1. This phosphorylation inhibits KCC2 activity, leading to elevate intracellular chloride levels in neurons.

Apoptotic Vesicles Derived from Mesenchymal Stem Cells Ameliorate Hypersensitivity Responses via Inducing CD8+ T Cells Apoptosis with Calcium Overload and Mitochondrial Dysfunction

open access: yesAdvanced Science, EarlyView.
The therapeutic potential of ApoVs derived from stem cells from human exfoliated deciduous teeth (SHED‐ApoVs) in the treatment of CD8+ T cell‐mediated hypersensitivity reactions is noteworthy. SHED‐ApoVs are capable of fusing with the plasma membrane of CD8+ T cells, which subsequently triggers a series of events characterized by calcium overload ...

Muscle‐Derived Small Extracellular Vesicles Mediate Exercise‐Induced Cognitive Protection in Chronic Cerebral Hypoperfusion

open access: yesAdvanced Science, EarlyView.
sEVs have a critical role in orchestrating interorgan crosstalk and mediating exercise‐induced therapeutic effects. Lin et al. demonstrates that sEVs miR‐17/20a‐5p mediates the muscle‐brain crosstalk and emphasizes the central role of mTOR signaling in executing molecular programs that can protect brain health in response to exercise.

Correlation Between Fecal Microbiota and Corticosteroid Responsiveness in Primary Immune Thrombocytopenia: an Exploratory Study

open access: yesAdvanced Science, EarlyView.
This study uses gut microbiome data to predict corticosteroid response in patients with immune thrombocytopenia (ITP). Fecal samples from 212 patients with ITP are sequenced. Six machine‐learning algorithms are used to train predictive models. The support vector machine‐based model integrated clinical data and selected microbial species, diversities ...
