The technique is used to harvest immune cells from the lung bronchoalveolar surfaces. Local anesthetic and mild conscious sedation (midazolam) is used. Subjects tolerate the procedure well and experience minimal side effects.

This technique is valuable yet complex and involves clinical risk by introducing a pathogen into a human. We have developed a detailed protocol.
