Platelet: Dense Granules
TXA2 ADP Calcium Histamine 5HT
Platelet: Alpha Granules
Fibrinogen Factor 5 + 7 TGF-beta PDGF P selectin
Mast Cells
5-HT, Histamine
Prostaglandins, Leukotrienes
TNF-Alpha
Endothelia: Intact
Antithrombin
Thrombomodulin
PGI2
TFPI (= Tissue Factor Pathway Inhibitor)
Endothelia: Broken
Thromboplastin Von Willebrand Factor PECAM1 ICAM1 E/P Selectin
Macrophages
Acute Cytokines: IL-1, TNFa, IL-6
Chronic: IL-12
Chemokine: CXCL8 (nø attractant)
TNF alpha and IL 1
Systemic: Fever, leukocytosis, acute phase response (liver, CRP and MRP), reduce appetite, promote sleep
Local:
1) Vascular - upregulate endothelial adhesin expression, procoagulant
2) Leukocytes - Activation, cytokine release
3) Fibroblasts - Replication, collagen production
IL-6
Acute phase response
IL-17
Chronic inflammation.
From Tø.
Increases nø and mø recruitment
IL-12
Chronic Inflammation.
From mø
Activates IFNy release -> Macrophage activation
