Chronic inflammation contributes to the pathogenesis of aging-associated diseases. Cells covering the surface of tissues such as the skin, lungs and intestines are constantly challenged by a wide range of environmental factors such as UV rays, particulate matter, chemicals as well as microbes. These stressors can damage cells and cause tissue injury that requires repair.
Cellular damage induces inflammation, which promotes tissue repair and guards against invading microbes. After successful regeneration, the inflammatory reaction needs to be terminated to establish normal tissue homeostasis.
Failure to properly regulate this response may result in uncontrolled chronic inflammation, which causes tissue damage and can result in severe diseases including chronic wounds, inflammatory bowel disease, psoriasis, rheumatoid arthritis, type 2 diabetes, hepatitis, and cancer.
CECAD studies the molecular and cellular mechanisms that cause chronic inflammation and its role in disease pathogenesis. CECAD researchers use state-of-the-art methods and a wide range of model organisms to study the molecules and pathways that regulate inflammation and contribute to disease.
Research Area E focuses on exploring:
CECAD scientists aim to decode the mechanisms that link cellular stress reactions to aging-associated diseases. This could contribute to the development of novel therapeutical approaches for these illnesses.
