Immune Mediated Studies

Immune-mediated or autoimmune diseases are serious and life threatening disorders. There a limited number of somewhat effective patient therapies available, but more research and drug development in this area are clearly needed. Good preclinical models exist for many diseases but for some, no robust animal models yet exist.

Relevant immune mediated diseases in man include:


Multiple sclerosis

Uveitis Rheumatoid arthritis Renal nephritis
Myasthenia gravis Diabetes Crohn’s disease Sjogren’s syndrome
Acute disseminated encephalomyelitis Asthma Psoriasis Eosinophilic esophagitis
Goodpastures’s syndrome Atopic dermatitis Inflammatory bowel disease


Typically, immune-mediated models involve combining the target antigen with an adjuvant which is effective in stimulating cell mediated immunity. In some cases, only the antigen is adequate to generate an immune-response. Potentiation of T helper cells leads to the production of certain immunoglobulins and effector T-cells, inflammation is a predominent finding. In preclinical studies, rodents are generally used and often special susceptible strains are required to generate the appropriate immune response. These special animals might include Lewis rats, BalbC mice, DBA-1 mice, APO-E mice, C57B6 mice, various transgenic and knock out mice, Duroc pigs, hairless guinea pigs, and minipigs.

Developed and optimized over the past 20 years, CBI offers a wide variety of optimized and validated immune-mediated models suitable for the assessment of allergic and immune-mediated disease. CBI is also skilled in developing new or custom models. A list of these models and information about each model is presented.

In vivo assessments are numerous and diverse may include clinical signs, neurologic signs, biomarkers, cytokines, body weights, food consumption, lameness scoring, joint diameter measurement scoring, plesthysmometry, clinical pathology, funduscopy, OCT, laser doppler, sillouette photography and customized assays.

Histopathologic assessment is a powerful tool in assessment of efficacy. Routine and special stains, histomorphometry, confocal microscopsy and immunohistochemistry are useful.
