Many Ways-One Destination: Different Types of Neutrophils Death.

Neutrophils constitute the most numerous populations of peripheral blood leukocytes, fulfilling the fundamental role in the development of the innate immune response. As the cells of the first line of defense, they guard the organism against the spread of pathogenic microorganisms. Neutrophils, similar to the other cells of the immune system, enter the path of death after fulfilling their biological function. Depending on the conditions that they are found in, they may undergo different types of cell death which requires the involvement of numerous signaling pathways. In this review article, we summarize the current state of knowledge regarding the different forms of neutrophil death, such as apoptosis, necrosis, necroptosis, autophagy, NETosis and pyroptosis.
