  • OBJECTIVES: The diagnosis of pulmonary embolism (PE) in the emergency department still poses difficulties because symptoms and signs are nonspecific. There is a need for more reliable noninvasive diagnostic tests to support clinical suspicion before the costly invasive procedures with complication r

  • The complement components C1r and C1s play a crucial role in innate immunity via activation of the classical complement cascade system. As initiators of the pathogen-induced signaling cascade, C1r and C1s modulate innate immunity. In order to understand the immune responses of teleost C1r and C1s, O

補体の相互作用 IMM.62

  • C1qがカスケードの最初となる。3つの方法で補体カスケードがはじまる。
  • (1)多価陰イオン表面(例えば、グラム陰性細菌のリポテイコ酸)
  • (2)バクテリアの多糖のホスホコリンに結合(例えば肺炎球菌のC蛋白質)
  • (3)抗原抗体複合体に結合して自然免疫と獲得免疫のエフェクター機構を結びつける。
  • 炭化水素鎖を認識するレクチンがカスケードの最初となる。
  • C3からはじまる。血漿中のC3が病原体の表面で自発的に活性化されることで補体反応がはじまる。
3つの経路は共通してC3 convertaseを生成。C3 convertaseはC3→C3a+C3b
C3a: C3a is a peptide mediator of local inflammation
C3b: C3b binds covalently to the bacterial cell membrane and opsonizes the bacteria
C5 convertaseはC3bにC3 convertaseが結合してできる
C5 converaseはC5→C5a+C5b
C5a: powerful peptide mediator of inflammation
C5b: C5b,C6,C7,C8,C9: membrane-attack complex


  • C5a,C3a,C4a: smooth muscle contraction.(IMM.75)
  • C5a,C3a: act on the endo thelial cells lining blood vessels to induce adhesion molecules.(IMM.75)
  • C5a>C3a>C4a: increase in blood flow, increase vascular permeability, increase binding of phagocytes to exdothielial cells.(IMM.76)
  • C5a: activates mast cells to release mediators, such as histamine and TNF-α. that contribute the inflammatory response(IMM.76).
  • C5a: acts directly on neutrophils and monocytes and attracting neutrophils and monocytes(IMM.75)
  • C3a: contributes to the pypotension and edema seen in endotoxic shock
  • C5a: activated by endotoxin, funcions in neutrophil chemotaxis
