The complement system, crucial for host defense, generates active products and MAC. Its dysregulation causes angioedema or hemolysis, while deficiencies impair immunity.

Area of Science:

  • Immunology
  • Biochemistry

Background:

  • The complement system comprises plasma proteins activated via classical or alternative pathways.
  • Activation leads to biologically active products and Membrane Attack Complex (MAC) assembly.
  • Control proteins maintain complement system homeostasis.

Purpose of the Study:

  • To elucidate the role of complement proteins in dermatologic disorders.
  • To understand the consequences of complement system dysregulation.

Main Methods:

  • Analysis of complement system activation pathways.
  • Investigation of complement protein functions.

Main Results:

  • Complement proteins are integral to the pathogenesis of various skin diseases.

  • Complement deficiencies impair host defense mechanisms.
  • Uncontrolled complement activation is linked to angioedema and chronic hemolysis.

    • Conclusions:

    • The complement system's balance is critical for immune function and preventing pathological conditions.
    • Aberrant complement activity contributes to significant clinical manifestations in dermatology and hematology.
