Neutrophils and natural killer (NK) cells are both categorized as innate immune cells that require Vitamin A for normal function [1]. Furthermore, both cell types are negatively impacted by zinc deficiency, which impairs their respective roles in phagocytosis and cytotoxicity [2], and they are distinguished by their different mechanisms for eliminating pathogens [3].

claimVitamin A is necessary for the normal function of innate immune cells, specifically natural killer (NK) cells, macrophages, and neutrophils.
claimZinc deficiency impairs innate immunity by negatively affecting the complement system, the cytotoxicity of natural killer cells, the phagocytic activity of neutrophils and macrophages, and the ability of immune cells to generate oxidants that kill invading pathogens.

claimUnlike neutrophils, macrophages, and dendritic cells, which use phagocytosis, natural killer (NK) cells attach to infected cells and release chemicals into them to kill them.
