Microvesicles in disease [PDF]

, 2014
On activation cells shed vesicles from their surface by the process of ectocytosis. These micro-vesicles or Ectosomes express phosphatidyl-serine (PS) on their surface, which can elicit a range of biological effects from immune-suppression to the ...

Leukocyte-derived microparticles and scanning electron microscopic structures in two fractions of fresh cerebrospinal fluid in amyotrophic lateral sclerosis: a case report

Journal of Medical Case Reports, 2012
Introduction Amyotrophic lateral sclerosis is a progressive neurodegenerative disorder characterized by degeneration of motoneuron cells in anterior spinal horns. There is a need for early and accurate diagnosis with this condition.

Extracellular microparticles derived from hepatic progenitor cells deliver a death signal to hepatoma-initiating cells

Journal of Nanobiotechnology, 2022
The malignant transformation of normal resident hepatic stem/progenitor cells has a critical role in hepatocarcinogenesis and the recurrence of hepatocellular carcinoma (HCC). We defined such hepatic progenitor cells as hepatoma-initiating cells.

Small tumour microparticle enhances drug delivery efficiency and therapeutic antitumour efficacy

Cancer Nanotechnology, 2022
Background Targeted delivery of chemotherapeutic drugs to tumour cells is a major challenge for cancer chemotherapy. Recent studies show that tumour cell-derived microparticles can be used as vectors to package chemotherapeutic drugs, and selectively ...

Immune cell-derived microparticles in polymyositis/dermatomyositis [PDF]

Annals of the Rheumatic Diseases, 2010
Microparticles are recently recognised players of intercellular communication. They are involved in signal transduction, cell activation and apoptosis. Their importance is also suggested in autoimmune diseases such as rheumatoid arthritis and systemic sclerosis. We investigated the role of microparticles in polymyositis/dermatomyositis, a group of rare

Immunomodulation by ectosomes [PDF]

, 2010
Considerable progress has been made in recognizing microvesicles as important mediators of intercellular communication rather than irrelevant cell debris.

Platelet-Derived Microparticles and Autoimmune Diseases

, 2023
Extracellular microparticles provide a means of cell-to-cell communication and can promote information exchanges between adjacent or distant cells. Platelets are cell fragments that are derived from megakaryocytes.

Neurokinin 1 receptor mediates membrane blebbing and sheer stress-induced microparticle formation in HEK293 cells.

PLoS ONE, 2012
Cell-derived microparticles participate in intercellular communication similar to the classical messenger systems of small and macro-molecules that bind to specialized membrane receptors. Microparticles have been implicated in the regulation of a variety

Mitigating the non-specific uptake of immunomagnetic microparticles enables the extraction of endothelium from human fat

Communications Biology, 2021
Antonyshyn et al. establish a methodology for acquiring human adipose tissue-derived microvascular endothelial cells that can be readily applied in future vascular tissue engineering applications.
