Q

TNF alpha and IL 1

A

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
