Summary
The complement system, crucial for immunity, can be deficient, increasing infection and autoimmune disease risks. Genetic testing and familial studies are vital for diagnosing and managing these complement deficiencies.
Area of Science:
- Immunology
- Biochemistry
Context:
- The complement system is a critical component of innate and adaptive immunity.
- It comprises serum and membrane proteins that interact in a regulated cascade.
- Its functions include antibacterial immunity, inflammation modulation, and immune complex clearance.
Purpose:
- To review the complement cascade.
- To discuss laboratory tests for assessing complement function.
- To outline major diseases linked to complement deficiencies.
Summary:
- Complement deficiencies, whether inherited or acquired, heighten susceptibility to bacterial infections and autoimmune disorders.
- While basic screening is possible, specialized laboratory diagnosis and genetic testing are often necessary.
- Congenital deficiencies warrant familial studies and prophylactic measures.
Impact:
- Highlights the clinical significance of complement system defects.
- Emphasizes the importance of timely diagnosis and genetic analysis.
- Provides a comprehensive overview for clinicians and researchers in immunology and related fields.

Immunodeficiency Diseases
3.5K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.

Complement System
10.5K
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 Tests
4.9K
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...

Factors Affecting the Risk of Infection
14.1K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Antimicrobial Proteins
10.6K
Antimicrobial proteins are important components of the immune system. They aid the body in combating pathogens by either killing them directly or hindering their replication processes. Four main types of antimicrobial substances are interferons, the complement system, iron-binding proteins, and antimicrobial proteins.
Interferons
Interferons (IFNs) are proteins produced by lymphocytes, macrophages, and fibroblasts infected with viruses. While IFNs cannot prevent viruses from entering and...
