Exosomes are secreted vesicles of ~30 to 150 nm diameter that play important roles in human health and disease. To better understand how cells release these vesicles, we examined the biogenesis most highly enriched exosome marker proteins, exosomal tetraspanins CD81, CD9, CD63. We show here endocytosis inhibits their vesicular secretion and, case CD9 triggers destruction. Furthermore, syntenin, a previously described factor, drives CD63 by blocking other inhibitors also induce plasma membrane accumulation Finally, is an expression-dependent inhibitor lysosomal proteins clathrin adaptor AP-2 mu2. These results suggest exosome-sized occurs primarily endocytosis-independent pathway.

Solid cancer contains a complicated communication network between cells and components in the tumor microenvironment (TME), significantly influencing progression of cancer. Exosomes function as key carriers signaling molecules these communications, including intricate signalings tumor-associated macrophages (TAMs) on TME. With their natural lipid bilayer structures biological activity that relates to original cell, exosomes have emerged efficient studies therapy. Intrigued by heterogeneity plasticity both exosomes, we regard macrophage-derived double-edged sword. For instance, TAM-derived educated TME, can promote resistance therapies, while generated vitro shown favorable potential Here, depict reasons for well manifold roles progression, metastasis, In particular, emphasize recent advancements modified diverse arguing are endowed with unique advantages macrophage origin. We outline challenges translating scientific discoveries into clinical therapy, aiming provide patients safe effective treatments.

Lysosomes help maintain cellular proteostasis, and defects in lysosomal positioning function can cause disease, including neurodegenerative disorders. The spatiotemporal distribution of lysosomes is regulated by small GTPases Rabs, which are activated guanine nucleotide exchange factors (GEFs). DENN domain proteins the largest family Rab GEFs. Using a cell-based assay, we screened DENND6A, member protein against all known Rabs identified it as potential GEF for 20 Rab34. Here, demonstrate that DENND6A activates Rab34, recruits RILP/dynein complex to lysosomes, promoting lysosome retrograde transport. Further, identify an effector Arl8b, major regulatory GTPase on lysosomes. We Arl8b peripheral activate Rab34 initiate transport, regulating nutrient-dependent juxtanuclear repositioning. Loss impairs autophagic flux. Our findings support model whereby Arl8b/DENND6A/Rab34-dependent trafficking controls autophagy.

Exosomes, which are nano-sized natural vesicles secreted by cells, crucial for intercellular communication and interactions, playing a significant role in various physiological pathological processes. Their characteristics, such as low toxicity immunogenicity, high biocompatibility, remarkable drug delivery capabilities—particularly their capacity to traverse the blood–brain barrier—make exosomes highly promising vehicles administration treatment of brain disorders. This review provides comprehensive overview exosome biogenesis isolation techniques, strategies loading functionalization exosomes, exosome-mediated barrier penetration mechanisms, with particular emphasis on recent advances exosome-based Finally, we address opportunities challenges associated utilizing system brain, summarizing barriers clinical translation proposing future research directions.

Abstract Over the recent years, it has become apparent that a deeper understanding of cell‐to‐cell and organ‐to‐organ communication is necessary to fully comprehend both homeostatic pathological states. Autophagy indispensable for cellular development, function, homeostasis. A crucial aspect autophagy can also mediate these processes through its secretory role. The autophagy‐derived secretome relays extracellular signals in form nutrients, proteins, mitochondria, vesicles. These crosstalk mediators functionally shape cell fate decisions, tissue microenvironment systemic physiology. diversity secreted cargo elicits an equally diverse type responses, which span over metabolic, inflammatory, structural adaptations disease We review here emerging role between different types organs discuss mechanisms involved.

Tumor-derived exosomes (TDEs) mediate oncogenic communication, which modifies target cells to reinforce a tumor-promoting microenvironment. TDEs support cancer progression by suppressing anti-tumor immune responses, promoting metastasis, and conferring drug resistance. Thus, targeting could improve the efficacy of anti-cancer treatments control metastasis. Current strategies inhibit TDE-mediated communication including drug-based genetic modification-based inhibition TDE release and/or uptake, have proved be inefficient. In this work, we propose surface engineering express foreign antigens that will trigger life-long anti-TDE responses. The possibility combining vaccines with other such as chemotherapy, radiotherapy, targeted therapy, surgery is also explored.

Mechanisms of Asymmetrical Exosome Release from Polarized Epithelial Cells: Implications for the Molecular Basis of Exosomal Heterogeneity DOI Creative Commons

Опубликована: Янв. 1, 2025

Abstract Exosomes are small extracellular vesicles of endocytic origin and secreted into the space by fusion between intraluminal vesicle (ILV)-containing multivesicular bodies (MVBs) plasma membrane. It has recently been shown that a single cell such as an epithelial secretes distinct types exosomes having different protein compositions (referred to “exosomal heterogeneity”). Polarized cells have two membrane domains (an apical basolateral membrane), which separated tight junctions. Two exosome subtypes, i.e., exosomes, asymmetrically from side side, respectively, cell. These subtypes independently regulated mechanisms in terms ILV (exosome precursor) biogenesis MVB transport On formation is ALIX–syntenin-1–syndecan-1 complex formed transported GTPases Rab27 Rab37. neutral sphingomyelinase 2 (nSMase2)-mediated ceramide production machinery, Rab39–UACA–BORC. also retained nonpolarized likely contribute genesis exosomal heterogeneity cells.
