CLEC7A and pulmonary tuberculosis: To explore the role of Dectin-1 in the host response to pulmonary TB, we aerosol inhalated 10 to 14 week-old female 129/Sv wild-type and Clec7a-/- mice (generated on a pure 129/Sv background [14]) with ±100 CFU of Mycobacterium tuberculosis H37Rv using an inhalation exposure system (Glas-Col, Terre Haute, IN, model no:099 A4212).
