Auto Immune & Metabolic Disease Models
Multiple Sclerosis Mouse Model: EAE
Disease Pathophysiology
MS is a CNS inflammatory disease caused by an autoimmune response against the myelin sheath insulation of nerve fibers, results in loss of motor-neuron control.
In mice, MOG peptide induces an auto-immune response, resulting in demyelination of nerve cells. Hindlimb and forelimb paralysis ensues and is scored/quantified.
Disease Induction
SC injection of 0.2mg MOG35-55 (myelin oligodendrocyte glycoprotein 35-55) in 0.4mg killed mycobacterium tuberculosis H37Ra, 0.1ml at 2 sites on the back at time= 0 hours.
IP injection of 600ng pertussis toxin at time= 2 hours and again at time= 22-26 hours
PD/Endpoint Analysis
Hindlimb/forelimb scoring of paralysis, scale 0-5
CD20, IL-17, GM-CSF analysis
Collagen Induced Arthritis Model
Disease Pathophysiology
CIA model driven by adaptive immune responses, includes presence of rheumatoid factor or anticitrullinated peptide antibody
Adjuvant induced models rely on innate and T-cell responses
Recombinant human Glucose-6-phosphate isomerase (rh-GPI) induces T-cell dependent inflammatory arthritis in genetically susceptible mice (male DBA/1)
Th2-driven model, sustained T-cell help to B cells leads to the production of high-affinity IgG1 antibodies against G6PI, arthritogenic
Disease Induction
Animals are injected SC at the base of the tail (2 sites of injection, 100µl/site), using a 27g needle with 400µg of rhGPI or collagen that has been emulsified 1:1 with CFA
PD/Endpoint Analysis
Scoring of footpad swelling: from 0 = normal, 1 = erythema and slight swelling of the major joint, 2 = moderate to severe swelling of the major joint, 3 = severe swelling of the entire paw.
IL-17, IL-1β, TNF, CD20 analysis
