Insights

Microparticles (MPs), small vesicles released from cells, are involved in physiological processes but increase in various diseases. Understanding their function aids in comprehending cell communication and disease origins.

Area of Science:

  • Biomedical science
  • Cell biology
  • Pathophysiology

Background:

  • Microparticles (MPs) are heterogeneous microvesicles originating from various cell types.
  • MP formation is a physiological process, but elevated circulating levels are linked to numerous pathologies.
  • Increased MPs derived from platelets, endothelial cells, and monocytes are observed in conditions with vascular dysfunction and inflammation.

Purpose of the Study:

  • To elucidate the role of microparticles in intercellular communication.
  • To understand the contribution of microparticles to the pathophysiology of diseases.
  • To investigate the functional properties of microparticles in health and disease.

Main Methods:

  • Analysis of microparticle populations in biological samples.
  • Characterization of microparticle origins (e.g., platelet, endothelial, monocyte).
  • Assessment of functional assays to determine microparticle activities.

Main Results:

  • Microparticle populations exhibit significant phenotypic and functional heterogeneity.
  • Elevated levels of specific MP types (platelet, endothelial, monocyte) correlate with vascular dysfunction and inflammatory diseases.
  • Documented association of MPs with conditions like coronary artery disease and thrombotic microangiopathies.

Conclusions:

  • Microparticles play a crucial role in intercellular signaling.
  • Increased microparticle levels are indicative of underlying pathological processes.
  • Further understanding of microparticle function is essential for disease mechanism elucidation.

Microbial Corrosion

Microbiologically Influenced Corrosion (MIC) is a significant form of material degradation caused by the metabolic activities of microorganisms. This phenomenon poses substantial challenges across various industries, including oil and gas, maritime, and water treatment sectors.MIC occurs when microorganisms, such as bacteria, archaea, and fungi, colonize metal surfaces, forming biofilms that alter the local electrochemical environment. These biofilms can lead to the production of corrosive...

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA ends...

Microtubules in Signaling

The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
