Chromatin Packaging

19.5K
Each human somatic cell contains 6 billion base pairs of DNA. Each base pair is 0.34 nm long, meaning each diploid cell contains a staggering 2 meters of DNA. This long DNA strand is packed inside a nucleus measuring only 10-20 microns in diameter with the help of specialized DNA-binding proteins called histones. Together they form a compact DNA-protein complex called chromatin. The chromatin is further compacted into higher-order structures. The highest level of compaction is achieved during...

Each human somatic cell contains 6 billion base-pairs of DNA. Each base-pair is 0.34 nm long, which means that each diploid cell contains a staggering 2 meters of DNA. How is such a long DNA strand packed inside a nucleus measuring only 10 - 20 microns in diameter? 
The chromatin
In combination with specialized DNA binding protein called Histones, the DNA double helix forms a compact DNA: protein complex called chromatin. The chromatin itself is further compacted into higher-order...

Complement System01:27

Complement System

10.9K
The complement system is a group of approximately 20 plasma proteins that strengthen the body's defenses against infections through opsonization, inflammation, and cell lysis. Opsonization involves coating pathogens with complement proteins, making them more recognizable and facilitating phagocyte engulfment. Certain complement proteins induce inflammation that attracts immune cells to the site of infection. Cell lysis involves the destruction of pathogens through the formation of a...

Complementation Tests00:49

Complementation Tests

6.3K
A complementation test is a simple cross to identify whether the two mutations are located on the same gene or different genes. It was first performed by Edward Lewis in the 1940s while working on fruit flies. He developed the test to identify the location and arrangement of different mutations on chromosomes.
Organisms heterozygous for different mutations are crossed pairwise in all combinations. If present on different genes, the mutations can complement each other by providing the missing...

Area of Science:

  • Immunology
  • Cell Biology
  • Biochemistry

Background:

  • Cells utilize extracellular vesicles (EVs) for intercellular communication, transferring various molecules.
  • EVs play roles in immune, metabolic, and coagulatory responses, and are linked to inflammatory diseases.
  • EVs possess immunomodulatory properties, driving interest in their connection with innate immunity.

Purpose of the Study:

  • To review current knowledge on the interaction between extracellular vesicles (EVs) and the complement system.
  • To explore the influence of EVs and complement interactions on inflammation and immune regulation.
  • To discuss the clinical relevance and therapeutic potential of EVs in translational medicine.

Main Methods:

  • Literature review of studies investigating extracellular vesicles (EVs) and the complement system.
  • Analysis of existing data on EV composition and complement factor association.
  • Synthesis of information regarding the impact of EV-complement interactions on inflammatory processes.

Main Results:

  • Elevated EV levels are observed in inflammatory conditions like sepsis and trauma.
  • EVs carry complement factors and regulators, modulating local and systemic inflammation.
  • EVs regulate complement activity, contributing to immune pro- and anti-inflammatory balance.

Conclusions:

  • The interplay between EVs and the complement system significantly impacts inflammatory responses.
  • Molecular mechanisms governing EV-complement crosstalk require further elucidation.
  • EVs hold promise as therapeutic vehicles in translational medicine due to their immunomodulatory roles.
