Over the past several years our laboratory research has focused on the interrelationship of cytokines, chemokines, and leukocyte activation during asthmatic-type airway and Th1/Th2 type immune responses. The development of a clinically relevant mouse cockroach allergen-induced airway model that demonstrates a number of in vivo correlates to human asthma has been successfully utilized to further elucidate novel mechanisms of pulmonary inflammation. The areas that have been successfully investigated using the allergic airway models include mast cell biology, eosinophilic inflammation, and T lymphocyte activation. In addition, we also examine the role of pulmonary viral infections (Respiratory Syncytial Virus; RSV) on exacerbation and increased development of allergic asthmatic responses. Using these models, we have specifically identified particular leukocyte populations that have an effect during different stages of asthmatic-like responses within the lung. Our most recent research has centered upon the role of important innate immune molecules that direct the direction of the immune response using defined mechanisms of activation. In particular, the toll-like receptor (TLR) system and a novel Notch ligand mediated activation of T lymphocytes has led to a number of important mechanistic studies.
