Innate Immune Cells

"Innate immune cells" is not the name of a single molecular target or receptor but rather refers collectively to several types of white blood cells that form part of the **innate immune system**—the body's first line of defense against pathogens. These include **neutrophils**, **macrophages**, **monocytes**, **eosinophils**, **basophils**, **mast cells**, and **natural killer (NK) cells** among others. Each has specialized roles in recognizing and eliminating pathogens through mechanisms such as phagocytosis, cytotoxicity, cytokine release, inflammation induction, and antigen presentation to adaptive immunity. While these cellular populations are critical in infection control and tissue homeostasis—and can be involved in diseases like cancer or chronic inflammation—they do not represent a singular therapeutic target but rather broad functional categories within immunology.[1][2][4] **Note:** "Innate immune cells" is an umbrella term for multiple distinct cellular targets with different molecular identities. It is *not* itself a canonical name for any one druggable protein/receptor/enzyme/transporter/etc., so it should be flagged as incorrect if used as such in structured databases.[1]
