Complement System01:27

Complement System

10.8K
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...

Physiological Barriers01:25

Physiological Barriers

5.3K
Physiological barriers are semi-permeable cellular structures restricting drug diffusion into intracellular compartments and tissues. There are six types of physiological barriers: blood endothelial, cell membrane, blood-brain, blood-cerebrospinal fluid (CSF), blood-placenta, and blood-testis barriers.
The blood endothelial barrier is the most porous of these. It allows all small ionized, un-ionized, and lipophilic molecules to pass through the endothelial lining into the interstitial space...

Mucosal Barrier of the Stomach01:25

Mucosal Barrier of the Stomach

2.4K
The gastric glands contain parietal cells that secrete hydrochloric acid (HCl) for digestion. The cells secrete HCl because it is highly corrosive and essential for breaking down food. To achieve this, they secrete hydrogen and chloride ions into the lumen of the gastric glands, which combine to form HCl.
Within parietal cells, carbonic acid is first formed through the reaction of water and carbon dioxide. The dissociation of carbonic acid releases bicarbonate and hydrogen ions. The bicarbonate...

Barriers to Effective Communication II01:21

Barriers to Effective Communication II

4.7K
The barriers to effective communication also include cultural barriers, semantic barriers, gender barriers, and time constraints.
Cultural barriers:
Differences in values, beliefs, religion, knowledge, and tradition can significantly impact communication. Awareness of nonverbal cues is critical, especially when conversing with a patient from a different culture. What appears appropriate in one culture may be inappropriate in another.
Semantic barriers:
As a result of their tendency to use...

Area of Science:

  • Neuroscience
  • Immunology
  • Physiology

Background:

  • The brain is an immune-privileged organ.
  • The blood-brain barrier (BBB) and complement system maintain brain homeostasis.
  • The complement system aids in defense, debris removal, and pathogen destruction.

Purpose of the Study:

  • To review the roles of the blood-brain barrier and complement system in the brain.
  • To explore the intersection and interaction between these two systems.
  • To understand how complement activation impacts BBB integrity and brain pathology.

Main Methods:

  • Literature review of studies on the blood-brain barrier.
  • Literature review of studies on the complement system.
  • Analysis of research on the interaction between the BBB and complement system.

Main Results:

  • The BBB regulates the brain microenvironment.
  • The complement system is crucial for brain development and homeostasis.
  • Over-activation of the complement system can compromise BBB integrity, leading to brain pathology.

Conclusions:

  • The blood-brain barrier and complement system are critical for brain health.
  • Their interaction is complex, with complement playing a dual role in normal function and pathology.
  • Further research is needed to fully elucidate the mechanisms linking complement and BBB dysfunction.
