Acute and Chronic Inflammation and Tissue Repair Flashcards

Rubor, calor tumor, dolor

Inflmmation is not a disease but a nonspecific response that has a salutary effect on its host
John Hunter
Discovered phagocytosis
Elie Metchnikoff
Established that chemical substances mediate vascular changes of inflammation
Sir Thomas Lewis
Five steps of the inflammatory response
- Recognition of the injurious agent
- Recruitment of leukocytes
- Removal of the agent
- Regulation of the response
- Resolution
Phases of acute inflammation
Initiation
Amplification
Destruction
Termination
Results in activation of soluble mediators and recruitment of inflammatory cells to the area
Initiation
Additional leukocytes and macrophages are recruited to the area
Amplification
T/F: Termination of inflammatory response occurs when the offending agent is eliminated
True
Outcome of acute inflammation
Elimination of the noxious stimuli followed by decline of the reaction and repair of the damaged tissue, or
Persistent injury resulting in chronic inflammation
Important receptors for sensing microbes, which when engaged, signals pathways to produce various mediators
Toll-like receptors
Activates caspase 1
Inflammasome
Cleaves inflammatory cytokine il-1B into its biologically active form
Caspase 1
Produced in mild injuries such as sunburn
Exudation
