The Induction of Autoimmune Arthritis and Sex differences in Mice Impact the Lung Inflammatory Response to Repetitive Inhalant Organic Dust Extract Exposures

Asthma, chronic bronchitis and COPD are common adverse respiratory health effects among persons exposed to agriculture organic dust work environments. Occupational inhalant exposures have been increasingly associated with the risk of rheumatoid arthritis (RA) disease development, particularly among males. Agriculture workers have increased risk of RA and generalized bone disease. Chronic lung disease is associated with production of characteristic autoantibodies associated with RA (e.g.anti-citrullinated antibodies), even in absence of RA disease. The mechanistic link between pulmonary inflammation and arthritis (and vice versa) remains poorly understood. Animal models are lacking.https://digitalcommons.unmc.edu/emet_posters/1004/thumbnail.jp
