The regulatory role of exosomes in venous thromboembolism

Frontiers in Cell and Developmental Biology, 2022
Exosomes are nanoscale endocytic vesicles, 30–150 nm in diameter, secreted by most cells. They mainly originate from multivesicular bodies formed by intracellular invagination of lysosomal microparticles, and released into the extracellular matrix after ...

Protein trafficking through the endosomal system prepares intracellular parasites for a home invasion [PDF]

, 2013
Toxoplasma (toxoplasmosis) and Plasmodium (malaria) use unique secretory organelles for migration, cell invasion, manipulation of host cell functions, and cell egress. In particular, the apical secretory micronemes and rhoptries of apicomplexan parasites

Pmel17 Initiates Premelanosome Morphogenesis within Multivesicular Bodies [PDF]

Molecular Biology of the Cell, 2001
Melanosomes are tissue-specific organelles within which melanin is synthesized and stored. The melanocyte-specific glycoprotein Pmel17 is enriched in the lumen of premelanosomes, where it associates with characteristic striations of unknown composition upon which melanin is deposited. However, Pmel17 is synthesized as an integral membrane protein.

Ultrastructural features of astroglial endosomal system state in sepsis-associated encephalopathy

Patologìâ, 2020
Sepsis-associated encephalopathy (SAE) is a common complication of sepsis, with a range of dysfunctional brain disorders. Astrocytes, as the main homeostatic brain cells, play a key role during adaptation of brain tissue to acute damage. The aim.

Design principles of the ESCRT-III Vps24-Vps2 module

eLife, 2021
ESCRT-III polymerization is required for all endosomal sorting complex required for transport (ESCRT)-dependent events in the cell. However, the relative contributions of the eight ESCRT-III subunits differ between each process.

Contribution of microscopy for understanding the mechanism of action against trypanosomatids [PDF]

, 2018
Transmission electron microscopy (TEM) has proved to be a useful tool to study the ultrastructural alterations and the target organelles of new antitrypanosomatid drugs.

Hrs and SNX3 functions in sorting and membrane invagination within multivesicular bodies.

PLoS Biology, 2008
After internalization, ubiquitinated signaling receptors are delivered to early endosomes. There, they are sorted and incorporated into the intralumenal invaginations of nascent multivesicular bodies, which function as transport intermediates to late ...

Release of Rice dwarf virus from insect vector cells involves secretory exosomes derived from multivesicular bodies

Communicative & Integrative Biology, 2009
Plant reoviruses in insect vector cells are sequestered in spherical multivesicular compartments. We demonstrated previously that the plant-infecting reovirus Rice dwarf virus (RDV) exploits multivesicular compartments for the transport and release of ...

WASH and Tsg101/ALIX-dependent diversion of stress-internalized EGFR from the canonical endocytic pathway [PDF]

, 2015
Stress exposure triggers ligand-independent EGF receptor (EGFR) endocytosis, but its post-endocytic fate and role in regulating signalling are unclear. We show that the p38 MAP kinase-dependent, EGFR tyrosine kinase (TK)-independent EGFR internalization ...

Insights into the function of ESCRT complex and LBPA in ASFV infection

Frontiers in Cellular and Infection Microbiology, 2023
The African swine fever virus (ASFV) is strongly dependent on an intact endocytic pathway and a certain cellular membrane remodeling for infection, possibly regulated by the endosomal sorting complexes required for transport (ESCRT).
