“Background Alveolar macrophages (MØ) represent the host’s first line of defense against Mycobacterium tuberculosis (Mtb). Phagocytosed Mtb bacilli are subjected to degradation via oxygen-dependent and -independent mechanisms. In the oxygen-dependent mechanism, MØ produce a variety of powerful mediators such as reactive oxygen species (ROS) and reactive nitrogen intermediates (RNI) that kill bacteria [1, 2]. The first step in the activation of innate host defenses against Mtb is the recognition of the pathogen. Host receptors involved in bacterial recognition and phagocytosis include complement receptors and pattern recognition receptors.
