Immune system communication

"Immune system communication" is not a specific molecule or receptor but rather refers to the complex network of interactions and signaling pathways that coordinate the activities of various cells and tissues within the immune system. This includes both innate and adaptive immunity, involving numerous cell types (such as T cells, B cells, macrophages), soluble factors (cytokines, chemokines), hormones (like ecdysone and insulin in Drosophila), and molecular pathways (e.g., JAK/STAT, NF-kB, cGAS–STING). Communication occurs through direct cell-cell contact as well as through secreted molecules that mediate responses such as pathogen recognition, inflammation regulation, antibody production, and maintenance of homeostasis. Disruption in these communication networks can result in pathological conditions including autoimmunity or immunodeficiency[1][2][3][4]. **Note:** "Immune system communication" is not a canonical therapeutic target; it describes a broad biological process involving many different molecules and receptors. For structured data extraction or drug discovery purposes you should specify an individual molecule/receptor involved in this process—such as "Toll-like receptor 4," "Interleukin 6 receptor," etc.—rather than using this general term.
