Primary immunodeficiencies occur with a frequency approaching that of cystic fibrosis (1:2500 live births). However, because they are perceived to be very rare and usually present with common infections, they are under-diagnosed. Often the diagnosis is not considered until substantial end-organ damage has occurred, by which time definitive treatment is only partially successful in preventing further infections. (more…)

Airway hyper-responsiveness in asthma may involve smooth muscle growth, a manifestation of airway remodelling. The involvement of inflammatory cells in the induction of airway smooth muscle growth was studied in vivo and ex vivo in a brown Norway rat model of asthma. Transfer of CD4 + T lymphocytes from ovalbuminsensitized animals induced an increase in airway smooth muscle mass in naive animals upon repeated ovalbumin challenge. Ex vivo, coculture of antigen-stimulated CD4 + T cells and airway smooth muscle cells led to myocyte proliferation and prolonged T-cell survival. (more…)

Acute inflammatory response constitute the first line of defense against infection pathogenesis and how immune system works as well as the initial stage in restoring injured tissue to normalcy. Acute inflammation is recognized by redness, swelling, heat and pain in the affected area. These symptoms stem from a multitude of events taking place within the inflamed site. The humoral arm of the immune response, including circulating antibodies and the complement system, is activated. (more…)
