BACKGROUND Microparticles (MPs), also called microvesicles (MVs) are plasma membrane-derived fragments with sizes ranging from 0.1 to 1μm. Characterization of these MPs is often performed by flow cytometry but there is no consensus on the appropriate negative control to use that can lead to false positive results. MATERIALS AND METHODS We analyzed MPs from platelets, B-cells, T-cells, NK-cell...
Systemic lupus erythematosus (SLE) is a systemic autoimmune disease presenting with a wide array of clinical manifestations and an elusive pathogenesis. A characteristic feature in SLE is the occurrence of autoantibodies against chromatin, double-stranded DNA, and RNA-binding ribonucleoproteins. Observations of defective clearance of dying cells in SLE combined with the generation and exposure ...
INTRODUCTION Mucopolysaccharidoses (MPS) are a group of systemic diseases characterised by a genetic deficiency of lysosomal enzymes that causes the accumulation of glycosaminoglycans in different tissues. The onset of symptoms usually occurs in early childhood, causing problems of otitis media, hearing loss and airway obstruction in the ENT area. OBJECTIVE Describing the audiological finding...
The degradation properties of the MPs is important to the long-term benefits of the use of the chitosan (CS) based hybrid MPs in bone tissue-engineering, because the degradation kinetics could affect a multitude of processes within the cell, such as cell growth, tissue regeneration, and host response. The aim of this study was to investigate the degradation of solid, hybrid CS microparticles (M...
Microparticles (MPs) are shed from activated and dying cells. They can transmit signals from cell to cell, locally or at a distance through the circulation. Monocytic MPs are elevated in different diseases, including bacterial infections. Here, we investigated how monocytic MPs activate endothelial cells. We found that MPs from lipopolysaccharide (LPS)-treated THP-1 monocytic cells bind to and ...
BACKGROUND AND AIM Previous studies on circulating microparticles (MPs) indicate that the majority of MPs are of a size below the detection limit of most standard flow cytometers. The objective of the present study was to establish a method to analyze MP subpopulations above the threshold of detection of a new generation BD FACSAria™ III digital flow cytometer. METHODS We analyzed MP subpopul...
Muscle hypertrophy following resistance training (RT) involves activation of myofibrillar protein synthesis (MPS) to expand the myofibrillar protein pool. The degree of hypertrophy following RT is, however, highly variable and thus we sought to determine the relationship between the acute activation of MPS and RT-induced hypertrophy. We measured MPS and signalling protein activation after the f...
Multiple pterygium syndrome (MPS) is a phenotypically and genetically heterogeneous group of rare Mendelian conditions characterized by multiple pterygia, scoliosis, and congenital contractures of the limbs. MPS typically segregates as an autosomal-recessive disorder, but rare instances of autosomal-dominant transmission have been reported. Whereas several mutations causing recessive MPS have b...
INTRODUCTION It have been found previously that colorectal cancer (CRC) is accompanied by atrophy of myenteric plexuses (MPs) localized close to the tumor. The aim of the study was to compare ultrastructure of MPs localized in the unchanged part of the colon wall distant to CRC tumor with the ultrastructure of MPs in the vicinity of CRC tumor. MATERIAL AND METHODS The present study was conduc...
Blood contains microparticles (MPs) derived from a variety of cell types, including platelets, monocytes, and endothelial cells. In addition, tumors release MPs into the circulation. MPs are formed from membrane blebs that are released from the cell surface by proteolytic cleavage of the cytoskeleton. All MPs are procoagulant because they provide a membrane surface for the assembly of component...
