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)

InflammationbullFirst described in Egyptian papyrus (3000 BC)
bullCelsus Roman writer from 1st century AD described 4 signs of inflammation
ndashrubor (redness)
ndashtumor (swelling)
ndashcalor (heat)
ndashdolor (pain)
ndashVirchow later added functio laesa (loss of function)
bullJohn Hunter Scottish surgeon 1793 ldquoInflammation is not a disease but a nonspecific response of the hostrdquo
bullMetchnikoff amp Erlich (shared Nobel prize 1908) purpose of inflammation is to bring cells and soluble mediators to site of infection damage

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

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

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

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

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 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 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

VDR increases Myocarditis in Males
VDR decreases Myocarditis in Females
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
