- Granule (cell biology)
A group of
leukocytescalled granulocytescontain granules and play an important role in the immune system. The granules of certain cells, such as Natural Killer Cells, contain components which can lead to the lysisof neighboring cells. The granules of leukocytesare classified as azurophilic granulesor specific granules.Leukocyte granules are released in response to immunological stimuli during a process known as degranulation.
The granules of
plateletsare classified as dense granules and alpha granules.
