Human immune system components

The human immune system is a complex, distributed network comprising a variety of cells (e.g., lymphocytes, neutrophils, macrophages, dendritic cells, natural killer cells) and molecular mediators (such as antibodies, cytokines, complement proteins, cellular receptors) that together identify and eliminate pathogens, distinguish self from non-self, and regulate tissue integrity and homeostasis. It includes both innate and adaptive arms, organized via diverse, often cell-type-specific proteins and receptors, with highly interconnected signaling networks. Because "human immune system components" encompasses multiple, distinct biological entities rather than a defined, singular molecular target, it is not a canonical entry suitable for structured drug target classification[2][4][5][6][7][8].
