Complement System01:27

Complement System

9.9K
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

6.1K
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...

Regulation of Food Intake01:30

Regulation of Food Intake

2.3K
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Microorganisms in Agriculture and Food industry

1.4K
Microorganisms play a crucial role in agriculture and the food industry, contributing to soil fertility, crop protection, and food production. Their functions range from nitrogen fixation and biopesticide production to fermentation and food preservation, making them indispensable to sustainable farming and food safety.Role in AgricultureNitrogen-fixing bacteria, such as Rhizobium (symbiotic) and Azotobacter (free-living), convert atmospheric nitrogen into ammonia through biological nitrogen...

Carbohydrate Metabolism01:36

Carbohydrate Metabolism

13.9K
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Background:

  • The classical complement system is a key component of innate immunity, crucial for pathogen defense.
  • Emerging research reveals a novel intracellular complement system, termed the complosome.
  • The complosome plays an unexpected role in regulating cellular processes.

Purpose of the Study:

  • To summarize current knowledge on the complosome's role in T cell metabolism.
  • To discuss the evolution of the complement system and its metabolic functions.
  • To highlight the significance of intracellular complement in T cell biology.

Main Methods:

  • Literature review of recent studies on intracellular complement and T cell metabolism.
  • Analysis of the evolutionary perspective of the complement system.
  • Synthesis of current data on complosome functions.

Main Results:

  • The complosome regulates key metabolic events in peripheral human T cells.
  • Intracellular complement is vital for T cell survival and effector function modulation.
  • The complosome's metabolic activities represent an evolutionarily conserved function.

Conclusions:

  • The complosome is a critical regulator of T cell metabolism and function.
  • Understanding intracellular complement opens new avenues in immunology and metabolic research.
  • The complement system's functions extend beyond pathogen defense to intracellular metabolic regulation.
