Endocytic signaling in leaves and roots: same rules different players. [PDF]

, 2012
To take up proteins and other components required by the cell, cells internalize a portion of the plasma membrane (PM), which invaginates to form a closed vesicle within the cytoplasm in a process known as endocytosis. The major plant endocytic mechanism

A Solution for Exosome‐Based Analysis: Surface‐Enhanced Raman Spectroscopy and Artificial Intelligence

Advanced Intelligent Discovery, EarlyView.
Exosomes are emerging as powerful biomarkers for disease diagnosis and monitoring. This review highlights the integration of surface‐enhanced Raman spectroscopy with artificial intelligence to enhance molecular fingerprinting of exosomes. Machine learning and deep learning techniques improve spectral interpretation, enabling accurate classification of ...

Crosstalk between autophagy inhibitors and endosome-related secretory pathways: a challenge for autophagy-based treatment of solid cancers

Molecular Cancer, 2021
Autophagy is best known for its role in organelle and protein turnover, cell quality control, and metabolism. The autophagic machinery has, however, also adapted to enable protein trafficking and unconventional secretory pathways so that organelles (such

ALIX binds a YPX(3)L motif of the GPCR PAR1 and mediates ubiquitin-independent ESCRT-III/MVB sorting. [PDF]

, 2012
The sorting of signaling receptors to lysosomes is an essential regulatory process in mammalian cells. During degradation, receptors are modified with ubiquitin and sorted by endosomal sorting complex required for transport (ESCRT)-0, -I, -II, and -III ...

Multivesicular body morphogenesis requires phosphatidyl-inositol 3-kinase activity [PDF]

Current Biology, 1999
Multivesicular bodies are endocytic compartments containing multiple small vesicles that originate from the invagination and 'pinching off' of the limiting membrane into the luminal space [1] [2] [3]. The molecular mechanisms responsible for the formation of these compartments are unknown.

Optimizing biophysical properties of cellular niches to enhance stem cell‐derived extracellular vesicle function in musculoskeletal regeneration

BMEMat, EarlyView.
Extracellular vesicles (EVs) derived from stem cells show promise for applications in regenerative medicine, but their scalability and yield remain challenges. This review explores the approaches for biophysical modulations within cell niches on EV properties, discusses the current clinical application of EVs, and provides an outlook on the existing ...

Hypoxia promotes EV secretion by impairing lysosomal homeostasis in HNSCC through negative regulation of ATP6V1A by HIF‐1α

Journal of Extracellular Vesicles, 2023
Tumour cells under hypoxia tend to modulate the number and contents of extracellular vesicles (EVs) to regulate the tumour microenvironment (TME) and thus promote tumour progression.

Analysis of cellular responses of macrophages to zinc ions and zinc oxide nanoparticles: a combined targeted and proteomic approach [PDF]

, 2014
Two different zinc oxide nanoparticles, as well as zinc ions, are used to study the cellular responses of the RAW 264 macrophage cell line. A proteomic screen is used to provide a wide view of the molecular effects of zinc, and the most prominent results

Exosome as bioactive nanovesicle for diagnostic and therapeutic applications in periodontitis

BMEMat, EarlyView.
This review introduces the mechanism that exosomes participate in the pathogenesis of periodontitis and their potential as biomarkers for early diagnosis and summarizes the application of cell‐ or plant‐derived exosomes or engineered exosomes in periodontitis or periodontal regeneration while proposing the perspective of translational application of ...

Variants of mitochondrial autophagy: Types 1 and 2 mitophagy and micromitophagy (Type 3)

Redox Biology, 2014
Mitophagy (mitochondrial autophagy), which removes damaged, effete and superfluous mitochondria, has several distinct variants. In Type 1 mitophagy occurring during nutrient deprivation, preautophagic structures (PAS) grow into cup-shaped phagophores ...
