E-mail: farrahk@bcm.tmc.edu <h3>SPECIFIC AIMS</h3> Mechanisms that initiate allergic lung inflammation are relevant to expression of diseases such as asthma, but the factors underlying resolution of inflammation are equally important. Immune cells recruited to sites of allergic inflammation express MMP9, but the physiological role of this enzyme in allergic lung disease remains unclear. We hypothesized that, much like MMP2, the closely related protease MMP9 may play an important role in facilitating the clearance of preapoptotic inflammatory cells in the allergic lung. <h3>PRINCIPAL FINDINGS</h3> <h3>1. MMP9 is expressed by recruited leukocytes during allergic lung
