Advanced Science, EarlyView.This study explores the opposing effects of the mGluR2 and mGluR3 receptors on amyloid precursor protein processing. mGluR2 promotes amyloidogenic cleavage, while mGluR3 favors non‐amyloidogenic pathways. Using a brain‐penetrant nanobody as a mGluR2 positive allosteric modulator, the study uncovers how its chronic activation aggravates amyloid‐β burden

Relationship between endosomes and lysosomes
, 2001 Delivery of endocytosed macromolecules to lysosomes occurs by means of direct fusion of late endosomes with lysosomes. This has been formally demonstrated in a cell-free content mixing assay using late endosomes and lysosomes from rat liver.

Advanced Science, EarlyView.This research identifies DTX3L as a critical tumor suppressor that inhibits epithelial‐mesenchymal transition (EMT), invasion and metastasis in gastric cancer. By functioning as an E3 ubiquitin ligase, DTX3L targets the master EMT regulator SNAI1 for GSK‐3β‐dependent proteasomal degradation.

eLife, 2016 Recycling of synaptic vesicles (SVs) is a fundamental step in the process of neurotransmission. Endocytosed SV can travel directly into the recycling pool or recycle through endosomes but little is known about the molecular actors regulating the switch ...

IRAP+ endosomes restrict TLR9 activation and signaling
, 2017 International audienceThe retention of intracellular Toll-like receptors (TLRs) in the endoplasmic reticulum prevents their activation under basal conditions. TLR9 is activated by sensing ligands in specific endosomal-lysosomal compartments.

Endogenous Engineering Reprograms Extracellular Vesicles for Enhanced Therapeutic Function
Advanced Science, EarlyView.This review explains how Extracellular vesicles‐producing cells can be endogenously engineered to load therapeutic proteins and nucleic acids. We summarize physiological and genetic strategies that harness native sorting pathways for selective cargo loading.

Selective rab11 transport and the intrinsic regenerative ability of CNS axons
eLife, 2017 Neurons lose intrinsic axon regenerative ability with maturation, but the mechanism remains unclear. Using an in-vitro laser axotomy model, we show a progressive decline in the ability of cut CNS axons to form a new growth cone and then elongate. Failure

The role of SARA1 Endosomes during neural precursor fate assignation
, 2012 Les endosomes SARA sont impliqués dans la ségrégation asymétrique des molécules Notch (Coumailleau, 2009). Pour savoir si ces caractéristiques étaient conservées dans le poisson zèbre, nous avons analysé les endosmes SARA dans le neuroépithélium : 1. Les

Advanced Science, EarlyView.ABSTRACT Despite the transformative impact of cancer immunotherapies such as immune checkpoint blockade, durable clinical responses remain limited. Increasing evidence indicates that antitumor immunity is governed not only by the tumor microenvironment, but also by systemic immune regulation mediated by peripheral immune organs. Among these, the spleen

Macrophage‐derived MLKL in alcohol‐associated liver disease: Regulation of phagocytosis
Hepatology, EarlyView., 2022 EtOH causes leaky gut allowing bacteria and PAMPs into the liver, resulting in hepatic inflammation and injury. We demonstrate that LPS induces STAT1‐mediated expression and phosphorylation of MLKL in macrophages and identify a novel function that myeloid MLKL translocates to phagosomes and lysosomes and regulates phagocytosis, which contributes to the
