Study Notes

Inflammation and Immune Response Overview

Inflammation is the body’s response to injury, infection, insult, or autoimmunity, involving a sequence of events.
The steps of the inflammatory response include recognition, leukocyte recruitment, removal of the inciting agent, regulation, and resolution.
Cardinal signs of inflammation include heat, redness, swelling, pain, and loss of function.
Acute inflammation involves immediate, nonspecific responses with neutrophils and macrophages, while chronic inflammation is a delayed, more specific response involving lymphocytes, plasma cells, and macrophages.
The acute inflammatory response is part of innate immunity and involves components like neutrophils, macrophages, and complement, with limited diversity and a rapid, nonspecific response.
Chronic inflammatory response is part of adaptive immunity, involving T and B lymphocytes, antibodies, and a highly specific, memory response to infection.
Robbins Pathology distinguishes between acute and chronic inflammatory responses.
Mediators of the acute inflammatory response include neutrophils, endothelial cells, mast cells, eosinophils, platelets, histamine, cytokines, arachidonic acid metabolites, and complement.
Neutrophils are central to acute inflammation, with the ability to phagocytose microorganisms and produce reactive oxygen species.
Platelets promote clot formation and contain inflammatory mediators.
Eosinophils defend against parasitic infections and are involved in allergic reactions and inflammatory reactions.
Mast cells, found in tissues, recognize microbial products, release preformed histamine granules, and synthesize lipid mediators and cytokines in response to trauma or IgE receptor cross-linking.
