Different Faces for Different Places: Heterogeneity of Neutrophil Phenotype and Function

Abstract EN

As the most abundant leukocytes in the circulation, neutrophils are committed to innate and adaptive immune effector function to protect the human body.

They are capable of killing intruding microbes through various ways including phagocytosis, release of granules, and formation of extracellular traps.

Recent research has revealed that neutrophils are heterogeneous in phenotype and function and can display outstanding plasticity in both homeostatic and disease states.

The great flexibility and elasticity arm neutrophils with important regulatory and controlling functions in various disease states such as autoimmunity and inflammation as well as cancer.

Hence, this review will focus on recent literature describing neutrophils’ variable and diverse phenotypes and functions in different contexts.
