1. What function do alveolar macrophages serve? What would happen to the respiration of an individualwho has a decreased number of alveolar macrophages due to an immune disorder?

7) The term "dust cell" refers to an alveolar macrophage. It is the most common type of immune cell found in the lungs' respiratory tract and BAL fluid. This cell targets microbes like viruses, bacteria, and fungi, as well as inhaled particles like dust, silica, and debris. The cell's toll-like receptor interacts with the microbial PAMP to activate the macrophage. Activated macrophages produce cytokines like IL-8 and TNF-alpha, which signal other immune cells to mount an immune response in the infected area. It also clears the lungs of excess surfactants. Low levels of alveolar macrophage due to immune disorders such as SCID and autoimmune diseases result in increased neutrophil recruitment, resulting in increased inflammation and pathogens infecting the lungs to a large extent
