Multiple immune cell types

The term "Multiple immune cell types" is a descriptive phrase referring to the collective populations of immune cells in the body, including both innate and adaptive lineages, such as T cells, B cells, natural killer cells, macrophages, monocytes, dendritic cells, granulocytes (e.g., neutrophils, basophils, eosinophils), and others. This entry does not refer to a single, discrete molecular entity or therapeutic target but rather to a heterogeneous group of functionally distinct cell populations with diverse roles in immunity, inflammation, infection, cancer, and tissue homeostasis. As such, it cannot be classified as a canonical molecular target or receptor for structured biomedical data applications[1][5][7].
