Autoantibodies targeting the complement system, a key part of innate immunity, can cause host damage and secondary deficiencies. Their role in disease requires further investigation.

Area of Science:

  • Immunology
  • Innate Immunity

Background:

  • The complement system is crucial for innate immunity but can cause harm when dysregulated.
  • Autoantibodies against complement components, regulators, and receptors are known to exist.

Purpose of the Study:

  • To review autoantibodies targeting the complement system.
  • To discuss their effects on complement levels and host susceptibility to infections.

Main Methods:

  • Literature review of studies on complement autoantibodies.

Main Results:

  • Autoantibodies against complement components can lead to their depletion, causing secondary complement deficiency.
  • The presence of these autoantibodies is associated with disease but causal links are not always clear.

  • Pathology likely involves multiple contributing factors, not just autoantibodies alone.

    • Conclusions:

    • Autoantibodies against complement components can impair immune function and increase infection risk.
    • Further research is needed to fully understand the pathogenic mechanisms and clinical significance of complement autoantibodies.
