Active pH Modulation by Proton Channel‐Peptide Nucleic Acid Complex for Effective siRNA Endosomal Escape

open access: yesSmall, EarlyView.
A bioinspired siRNA nanocarrier is engineered by integrating an influenza A M2 proton channel with siRNA through a peptide nucleic acid linker on liposome surfaces. Active proton transport amplifies osmotic stress within endosomes, triggering membrane rupture and cytosolic release.

Magnaporthe Rab5 homologs show distinct functions in nerve growth factor (NGF)-mediated neurite outgrowth and cell differentiation

open access: yesJournal of Integrative Agriculture, 2015
Nerve growth factor (NGF) binds to TrkA and forms a NGF/TrkA complex at the cell surface, which is then internalized into signaling endosomes and promotes neuronal survival and neurite outgrowth.

Rab5‐dependent endocytosis of KCa2.3

open access: yesThe FASEB Journal, 2011
We demonstrated that recycling of KCa2.3 is dependent upon Rab35/EPI64C and RME‐1. Herein, we report our initial studies on the mechanism by which KCa2.3 is retrieved from the plasma membrane. Using a biotin ligase acceptor peptide‐tagged KCa2.3 construct, we demonstrate that expression of a dominant active Rab5 (Q79L) results in the colocalization of ...

Activation of peripheral NOP receptors reduces periorbital mechanical allodynia evoked by CGRP in mice

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Migraine is a neurovascular disorder largely mediated by calcitonin gene‐related peptide (CGRP). This study explores the role of the nociceptin/orphanin FQ (N/OFQ)–N/OFQ receptor (NOP) system in CGRP‐induced periorbital mechanical allodynia (PMA) in mice.

Rab5 and Rac Team Up in Cell Motility [PDF]

open access: yesCell, 2008
Cell motility requires actin assembly mediated by Rac, a Rho family GTPase. In this issue, Palamidessi et al. (2008) show that Rab5-directed trafficking of Rac to the cell membrane is required for Rac-mediated actin assembly. Trafficking of Rac may influence the mode of cell migration during morphogenesis and cancer metastasis.

The sorting nexin Snx21 promotes flotillin‐mediated endocytosis

open access: yesThe FEBS Journal, EarlyView.
In this study, we describe a novel function of the previously uncharacterized Snx21 protein as a specific positive regulator of flotillin‐mediated endocytic trafficking. Snx21 is recruited to endosomal membranes via binding to PI(3)P, and it colocalizes with flotillins on the surface of late endosomes.

Rab5(Q79L) interacts with the carboxyl terminus of RUFY3 [PDF]

open access: yesInternational Journal of Biological Sciences, 2010
The small GTPase Rab5 controls the fusogenic properties of early endosomes through activation of effector proteins. Expression of a GTPase-defective mutant, Rab5(Q79L), is known to cause formation of enlarged early endosomes. To identify proteins interacting with this GTP-bound form of active Rab5 1, we used a two-hybrid system to screen a human fetal ...

Interactional Endocytosis and Transmembrane Transport Promote Cellular Internalization of Nano‐Delivered RNA Drugs for Efficient Control of Crop Diseases

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Botrytis cinerea is a widespread plant pathogenic ascomycete that causes grey mould in over 1400 species and impacts global crop yields. Double‐stranded RNA (dsRNA)‐induced gene silencing is a promising technology for pest control, but efficient delivery remains a major challenge.

Regulation of Liver Metabolism by the Endosomal GTPase Rab5

open access: yesCell Reports, 2015
The liver maintains glucose and lipid homeostasis by adapting its metabolic activity to the energy needs of the organism. Communication between hepatocytes and extracellular environment via endocytosis is key to such homeostasis. Here, we addressed the question of whether endosomes are required for gluconeogenic gene expression.

Understanding extracellular vesicle biology, isolation, and characterization: The theory of EV‐erything

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Extracellular vesicles (EVs), especially exosomes, are nanoparticles increasingly recognized as key regulators of intercellular communication in both physiological and pathological aspects. Despite rapid progress, inconsistencies in nomenclature, isolation, and characterization continue to restrict translational advancement.
