Specific granules are secretory vesicles found exclusively in cells of the immune system called granulocytes.
It is sometimes described as applying specifically to neutrophils,[1] and sometimes the term is applied to other types of cells.
[2] These granules store a mixture of cytotoxic molecules, including many enzymes and antimicrobial peptides, that are released by a process called degranulation following activation of the granulocyte by an immune stimulus.
[3] Examples of cytotoxic molecule stored by specific granules in different granulocytes include: A specific granule deficiency can be associated with CEBPE.
