Antiphospholipid antibodies, crucial for innate immunity, are beneficial for host defense. They only become harmful in susceptible individuals during adverse intravascular events, suggesting a protective role.

Area of Science:

Immunology
Autoimmunity

Background:

Antiphospholipid antibodies are implicated in antiphospholipid syndrome.
Their role in innate immunity is increasingly recognized.

Purpose of the Study:

To review evidence on the beneficial roles of antiphospholipid antibodies.
To explore the transition of these antibodies from protective to pathogenic.

Main Methods:

Literature review of studies on antiphospholipid antibodies and their functions.
Analysis of evidence linking natural autoantibodies to antiphospholipid syndrome.

Main Results:

Antiphospholipid antibodies originate from natural autoantibodies with beneficial functions.
These antibodies play key roles in the innate immune response.

Pathogenicity arises under specific adverse intravascular conditions in susceptible individuals.

Conclusions:

Antiphospholipid antibodies serve a protective purpose in host defense.
Their pathogenic potential is context-dependent, linked to specific intravascular events.
