Asthma was induced by th e sensitization and chal-lenge with ovalbumin (OVA) in mice. B-cell activating factor (BAFF) plays a role in mature B cell generation BAFF expression was change d in OVA-induced mice and whether the control of BAFF expression level alleviates the symptom of bronchial asthma. BAFF expression was detected in alveolar-associated cells surrounding bronchi of OVA-induced mouse lung tissues. BAFF protein was also increased in OVA-induced mouse serum. The increased BAFF transcripts was detected in OVA-induced mouse splenocytes. OVA-induced asthma was associated with the increased number of eosinophils in bron-choalveolar lavage fluid ( BALF). When TACI:Fc scav-enging soluble BAFF was in jected to OVA-induced mice, a significant inhibition was detected in the thickness of airway smooth muscle and glycol-con-taining cellular elements in airway that were vi-sualized by hematoxylin/eosin Y and periodic acid-Schiff staining, respectively. In addition, when mice were treated with TAtein level was decreased in alveolar-associated cells surrounding bronchi of OVA-induced mouse lung tissues compared to control mice. When compared to OVA-induced control, TACI:Fc treatment reduced the percentage of non-lymphoid cells and no changes were detected in lymphoid cell population. Hypodiploid cell formation in BALF was decreased by OVA-challenge but it was recovered by TACI:Fc treatment. Collectively, data suggest that asthmatic symptom could be alleviated by scavenging BAFF and then BAFF could be a novel target for the devel-opment of anti-asthmatic agents.
