Degranulation is a process in which certain cells, particularly white blood cells called granulocytes (neutrophils and eosinophils), release their granules into the surrounding environment. These granules contain various enzymes and proteins that can help fight off infections or inflammation. The degranulation process is triggered by certain stimuli, such as exposure to allergens or pathogens, which activate the cells and cause them to release their contents. This release of granules can contribute to the immune response and help protect the body from harm.
