Hapten immunology and allergic reactions in humans

Immunology of allergic contact dermatitis.

Allergic contact dermatitis (ACD) is a T-cell mediated skin inflammation caused by repeated skin exposure to contact allergens. This review summarizes current knowledge on the immunology of ACD. Different phases in ACD are distinguished, i.e. sensitization, elicitation and resolution phases. We discuss contact allergen presentation and the central role of antigen presenting cells during sensiti...

Pathophysiology and immunology of allergic bronchopulmonary aspergillosis.

Allergic bronchopulmonary aspergillosis (ABPA) is a complication of persistent asthma and cystic fibrosis (CF), diseases in part characterized by excessive viscous mucus and compromised mucociliary clearance. Inhaled conidia of Aspergillus fumigatus are able to persist and germinate, releasing exoproteases and other fungal products that further compromise clearance, breach the epithelium, and a...
