Chu Laboratory

Our lab’s mission is to understand the mechanisms of airway bacterial infections in patients with asthma or COPD, and to discover novel therapeutic approaches to restore host defense functions. We have identified impaired Toll-like receptor 2 (TLR2) signaling, and reduced production of host defense molecule short palate, lung, and nasal epithelium clone 1 (SPLUNC1) in allergic airways. Furthermore, we have found that cigarette smoke exposure dampens airway epithelial innate immune responses to bacteria such as Mycoplasma pneumonaie and Moraxella catarrhalis.
