Insights

Cell surface proteins like DAF and CD59 protect tissues from complement damage. Recent studies show these membrane complement regulatory proteins are key in autoimmune diseases and cellular immunity.

Area of Science:

  • Immunology
  • Cell Biology
  • Complement System

Background:

  • Cell surface proteins protect host tissues from complement-mediated bystander injury.
  • Key proteins include decay-accelerating factor (DAF, CD55), membrane cofactor protein (MCP, CD46), complement receptor 1 (CR1, CD35), and CD59.
  • While rare, abnormal function of these proteins can be linked to disease.

Purpose of the Study:

  • To review recent advances in the in vivo biology of membrane complement regulatory proteins.
  • To discuss the relevance of these proteins in human disease pathogenesis.
  • To explore their therapeutic potential.

Main Methods:

  • Review of recent scientific literature and animal model studies.
  • Analysis of the role of membrane complement regulatory proteins in immune responses.
  • Examination of their involvement in autoimmune and inflammatory diseases.

Main Results:

  • Membrane complement regulatory proteins are crucial modulators of tissue injury in autoimmune and inflammatory conditions.
  • Emerging evidence indicates a significant role in regulating cellular immunity.
  • These proteins offer potential therapeutic targets for various diseases.

Conclusions:

  • Membrane complement regulatory proteins are vital in protecting tissues and modulating immune responses.
  • Their dysregulation contributes to pathogenesis in autoimmune and inflammatory diseases.
  • Further research into their in vivo biology can lead to novel therapeutic strategies.

Global Regulatory Systems01:28

Global Regulatory Systems

Global regulatory systems in bacteria enable rapid and coordinated responses to environmental changes by integrating sensory inputs with gene expression, ensuring efficient adaptation to fluctuating conditions. Key global regulatory mechanisms include regulons, two-component systems, sigma factors, and secondary messengers.Regulons and Global RegulatorsA regulon is a collection of genes and operons controlled by a common global regulator. These regulators enable bacteria to prioritize resource...

Complement System01:27

Complement System

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...

Antimicrobial Proteins01:23

Antimicrobial Proteins

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...

Introduction to Membrane Proteins

The cell membrane, or plasma membrane, is an ever-changing landscape. It is described as a fluid mosaic where various macromolecules are embedded in the phospholipid bilayer. Among the macromolecules are proteins. The protein content varies across cell types. For example, mitochondrial inner membranes contain ~76% protein content, while myelin contains ~18% protein content. Individual cells contain many types of membrane proteins—red blood cells contain over 50—and different cell...

Rab Proteins01:14

Rab Proteins

Rab proteins constitute the largest family of monomeric GTPases, of which 70 members are present in humans. Rab proteins and their effectors regulate consecutive stages of vesicle transport such as vesicle transport, docking, and fusion to the correct recipient membrane.
Rab proteins switch between a cytosolic, GDP-bound inactive state and a membrane-anchored, GTP-bound active state. By themselves, Rabs show slow rates of GDP/GTP exchange and GTP hydrolysis. Thus, Rab proteins are considered...

Surface Membrane Barriers

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...
