Insights

The absent in melanoma 2 (AIM2) and interferon-inducible protein 16 (IFI16) inflammasomes play distinct roles in infectious and aseptic inflammation. Understanding their competition is key to targeting inflammatory diseases.

Area of Science:

  • Immunology
  • Molecular Biology
  • Cell Biology

Background:

  • Absent in melanoma 2 (AIM2) and interferon-inducible protein 16 (IFI16) are intracellular innate immune receptors.
  • These receptors recognize double-stranded DNA, initiating inflammasome assembly.
  • Inflammasome activation leads to IL-1β and IL-18 secretion and pyroptosis.

Purpose of the Study:

  • To review the roles of AIM2 and IFI16 in infectious disease and aseptic inflammation.
  • To explore the competitive interactions between AIM2 and IFI16 during inflammatory processes.

Main Methods:

  • Literature review of studies on AIM2 and IFI16 inflammasomes.
  • Analysis of the functional outcomes of AIM2 and IFI16 activation in different inflammatory contexts.

Main Results:

  • AIM2 inflammasome plays a protective role in infectious diseases.
  • IFI16 inflammasome is implicated in aseptic inflammatory illnesses.
  • There is a competitive relationship between AIM2 and IFI16 during inflammation.

Conclusions:

  • AIM2 and IFI16 have contrasting roles in infectious versus aseptic inflammation.
  • The competition between AIM2 and IFI16 influences inflammatory responses.
  • Targeting these inflammasomes may offer therapeutic strategies for inflammatory conditions.

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...

Factors Affecting the Risk of Infection

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...
