17
Q

Types of ILs in the ınflammation

A

IL1
IL6
IL8
Stimulate the chemotaxis
Induce extravascularization of granulocytes
Fever

18
Q

TNF in inflammation

A

Leukocytosis
Fever
Stimulates prostaglandins production

19
Q

Acute phase response

A

Within hours or days
Changes in the concentrations of plasma proteins= fibrinogen, C-reactive protein
Increased erythrocyte sedimentation rate
Fever
Increased numbers of leukocytes
Skeletal muscle catabolism
Negative nitrogen balance

TNF-a

A

Pro-inflammatory factor
Binds to receptor
Activates NF-kB
