Interleukin family protein (IL (collective abbreviation; specific members, e.g., IL-1, IL-6, have distinct abbreviations))

Interleukin family proteins are a large group of cytokines—secreted signaling proteins—that are principally produced by leukocytes and other immune cells. Their primary role is to mediate communication between cells of the immune system and regulate immune and inflammatory responses[2][8][6]. Interleukins exhibit a wide array of biological functions, including the activation, proliferation, and differentiation of lymphocytes, modulation of hematopoiesis, mediation of inflammatory and anti-inflammatory responses, and orchestration of both innate and adaptive immunity[2][4][8]. Each interleukin (e.g., Interleukin-1, Interleukin-6, Interleukin-17) is an individual protein with a unique receptor and pathway, and many are important therapeutic targets in diseases such as autoimmune disorders, cancer, and infection[3][5][7]. **Important limitation**: "Interleukin family protein" is not a suitable single target for drug discovery, therapeutic modulation, or biomarker studies. Each interleukin (e.g., Interleukin-1, Interleukin-6, etc.) is a distinct therapeutic target with unique structure, function, disease role, and pharmacology[2][6]. For actionable, structured data, the specific interleukin should be specified—for example, "Interleukin-6," "Interleukin-17," or "Interleukin-1 receptor."
