| Research Abstract |
Pulmonary collectins play important roles in innate immunity of the lung. In this study, we found that pulmonary collectins attenuate autophagy induced by L. pneumophila infection. Furthermore, pulmonary collectins inhibit the secretion of effector molecules into host cells via type IV secretion system of L. pneumophila. These results suggest that pulmonary collectins protect host cells by the previously uncharacterized host defense mechanism against intracellular pathogen.
