Do goblet cell mediators co-operatively prevent gut microbiota from causing spontaneous colitis?

Inflammatory Bowel Diseases, including Crohn’s disease and ulcerative colitis are characterized by chronic intestinal inflammation and tissue damage. There are trillions of bacteria found  within the human intestine and IBDs are thought to develop when mucus barriers that normally keep these  bacteria inside the gastrointestinal tract become impaired,  allowing bacteria to escape out of the gut lumen and causing  chronic inflammation. While the role of epithelial cells in promoting barrier function is well known, the protective actions of the mucus barrier are relatively understudied.

The role of the airway epithelium NLRP3 inflammasome in asthma pathogenesis

Asthma is a respiratory disease that afflicts more than two million Canadians. Asthmatics experience both airway inflammation and changes in the airway structure, called airway remodeling, when they inhale allergens, pollutants and other insults, and this leads to an exacerbation. The airway epithelium is the first site of contact for inhaled substances and has been shown to be different in asthmatics than in non-asthmatics.

Childhood lung diseases: Infectious and inflammatory mechanisms

Lungs are for life. Unfortunately, the most frequent long-term illnesses in children and babies are respiratory system conditions. Children's lungs can be damaged in many ways: bacterial and viral infections, asthma, or faulty genes causing thick mucus to accumulate in the lungs of children with cystic fibrosis. Even the oxygen and artificial ventilation needed to sustain the lives of premature babies can cause lasting lung damage.
