Summary Inflammationbull Inflammation progresses from an innate immune response to

acute inflammation and then to either resolution of inflammation or chronic inflammationpathology

bull Immune mediators (ie cytokines) are responsible for redness swelling heat amp pain

bull Inflammation consists of immune cells infiltrating an organtissue

bull Inflammation is closely intertwined with the process of repair

bull Inflammation amp repair can both protect or damage tissues

bull Inflammation is a critical component of heart disease (CVD) cancer autoimmune diseases (ADs) like diabetes and chronic respiratory diseases like COPD

bull Inflammation is also a critical component of chronic diseases that are not the top causes of death such as allergies asthma obesity and ADs like lupus or multiple sclerosis

Main Pointsbull Acute inflammation leads to chronic disease in

susceptible individuals

bull Low doses of toxinschemicals amp injury can potentially launch a damaging immune response

bull Toxins and chemicals activate the Inflammasome driving a proinflammatory and profibrotic response (ie Th2 response)

bull Sex hormones regulate inflammation and the inflammasome

bull Immune mediators (ie cytokines) are responsible for redness swelling heat amp pain

bull Inflammation consists of immune cells infiltrating an organtissue

bull Inflammation is closely intertwined with the process of repair

bull Inflammation amp repair can both protect or damage tissues

bull Inflammation is a critical component of heart disease (CVD) cancer autoimmune diseases (ADs) like diabetes and chronic respiratory diseases like COPD

bull Inflammation is also a critical component of chronic diseases that are not the top causes of death such as allergies asthma obesity and ADs like lupus or multiple sclerosis

Main Pointsbull Acute inflammation leads to chronic disease in

Summary Inflammationbull Inflammation progresses from an innate immune response to

acute inflammation and then to either resolution of inflammation or chronic inflammationpathology

bull Immune mediators (ie cytokines) are responsible for redness swelling heat amp pain

bull Inflammation consists of immune cells infiltrating an organtissue

bull Inflammation is closely intertwined with the process of repair

bull Inflammation amp repair can both protect or damage tissues

bull Inflammation is a critical component of heart disease (CVD) cancer autoimmune diseases (ADs) like diabetes and chronic respiratory diseases like COPD

bull Inflammation is also a critical component of chronic diseases that are not the top causes of death such as allergies asthma obesity and ADs like lupus or multiple sclerosis

Main Pointsbull Acute inflammation leads to chronic disease in

susceptible individuals

bull Low doses of toxinschemicals amp injury can potentially launch a damaging immune response

bull Toxins and chemicals activate the Inflammasome driving a proinflammatory and profibrotic response (ie Th2 response)

bull Sex hormones regulate inflammation and the inflammasome

What is the role of Innate Immunity in the pathogenesis of chronic diseases

bull Innate Immunity initiates inflammation ie Toll-like receptors (TLRs)

bull Innate Immunity determines the nature phenotype of the adaptive immune response ie T helper type (Th)1 vs Th2 vs Th17

bull Innate Immunity initiates regulatory mechanisms ie T regulatory cells and regulatory cytokines

bull The balance between a proinflammatory response and regulation of the response and regulation of repair mechanisms determines whether injury proceeds to chronic disease

Summary Inflammationbull Inflammation progresses from an innate immune response to

acute inflammation and then to either resolution of inflammation or chronic inflammationpathology

bull Immune mediators (ie cytokines) are responsible for redness swelling heat amp pain

bull Inflammation consists of immune cells infiltrating an organtissue

bull Inflammation is closely intertwined with the process of repair

bull Inflammation amp repair can both protect or damage tissues

bull Inflammation is a critical component of heart disease (CVD) cancer autoimmune diseases (ADs) like diabetes and chronic respiratory diseases like COPD

bull Inflammation is also a critical component of chronic diseases that are not the top causes of death such as allergies asthma obesity and ADs like lupus or multiple sclerosis

Main Pointsbull Acute inflammation leads to chronic disease in

susceptible individuals

bull Low doses of toxinschemicals amp injury can potentially launch a damaging immune response

bull Toxins and chemicals activate the Inflammasome driving a proinflammatory and profibrotic response (ie Th2 response)

bull Sex hormones regulate inflammation and the inflammasome

Summary Inflammationbull Inflammation progresses from an innate immune response to

acute inflammation and then to either resolution of inflammation or chronic inflammationpathology

bull Immune mediators (ie cytokines) are responsible for redness swelling heat amp pain

bull Inflammation consists of immune cells infiltrating an organtissue

bull Inflammation is closely intertwined with the process of repair

bull Inflammation amp repair can both protect or damage tissues

bull Inflammation is a critical component of heart disease (CVD) cancer autoimmune diseases (ADs) like diabetes and chronic respiratory diseases like COPD

bull Inflammation is also a critical component of chronic diseases that are not the top causes of death such as allergies asthma obesity and ADs like lupus or multiple sclerosis

Main Pointsbull Acute inflammation leads to chronic disease in

susceptible individuals

bull Low doses of toxinschemicals amp injury can potentially launch a damaging immune response

bull Toxins and chemicals activate the Inflammasome driving a proinflammatory and profibrotic response (ie Th2 response)

bull Sex hormones regulate inflammation and the inflammasome

Summary Inflammationbull Inflammation progresses from an innate immune response to

acute inflammation and then to either resolution of inflammation or chronic inflammationpathology

bull Immune mediators (ie cytokines) are responsible for redness swelling heat amp pain

bull Inflammation consists of immune cells infiltrating an organtissue

bull Inflammation is closely intertwined with the process of repair

bull Inflammation amp repair can both protect or damage tissues

bull Inflammation is a critical component of heart disease (CVD) cancer autoimmune diseases (ADs) like diabetes and chronic respiratory diseases like COPD

bull Inflammation is also a critical component of chronic diseases that are not the top causes of death such as allergies asthma obesity and ADs like lupus or multiple sclerosis

Main Pointsbull Acute inflammation leads to chronic disease in

susceptible individuals

bull Low doses of toxinschemicals amp injury can potentially launch a damaging immune response

bull Toxins and chemicals activate the Inflammasome driving a proinflammatory and profibrotic response (ie Th2 response)

Summary Inflammationbull Inflammation progresses from an innate immune response to

acute inflammation and then to either resolution of inflammation or chronic inflammationpathology

bull Immune mediators (ie cytokines) are responsible for redness swelling heat amp pain

bull Inflammation consists of immune cells infiltrating an organtissue

bull Inflammation is closely intertwined with the process of repair

bull Inflammation amp repair can both protect or damage tissues

bull Inflammation is a critical component of heart disease (CVD) cancer autoimmune diseases (ADs) like diabetes and chronic respiratory diseases like COPD

bull Inflammation is also a critical component of chronic diseases that are not the top causes of death such as allergies asthma obesity and ADs like lupus or multiple sclerosis

Main Pointsbull Acute inflammation leads to chronic disease in

susceptible individuals

bull Low doses of toxinschemicals amp injury can potentially launch a damaging immune response

bull Toxins and chemicals activate the Inflammasome driving a proinflammatory and profibrotic response (ie Th2 response)

bull Sex hormones regulate inflammation and the inflammasome
