Lung immunology is a field of research focused on understanding the immune response within the lungs. This includes studying how the immune system detects and responds to infections, allergens, pollutants, and other stimuli that can impact lung health. Researchers in this area may investigate the role of different immune cells, cytokines, and other signaling molecules in lung diseases such as asthma, chronic obstructive pulmonary disease (COPD), and pneumonia. Understanding lung immunology is crucial for developing new treatments and interventions to improve respiratory health and prevent lung-related illnesses.
