Immunomodulation via cytokine and growth factor secretion

Immunomodulation via cytokine and growth factor secretion" does not refer to a specific molecular target but instead to a major immunoregulatory process. This process involves secretion of diverse proteins (cytokines and growth factors) by immune and non-immune cells, which then act through binding to specific cell surface receptors on immune cells such as T cells, dendritic cells, NK cells, and B cells. These secreted factors orchestrate the activation, proliferation, differentiation or suppression of immune responses. Cytokines are the main mediators of both innate and adaptive immunity and include interleukins, interferons, chemokines, and colony-stimulating factors, among others. Growth factors overlap with cytokines in both structure and function and control cell growth, survival, and differentiation. Both classes can act in autocrine, paracrine, or endocrine fashions, and their dysregulation is central to a variety of disease processes such as chronic inflammation, cancer, and autoimmune diseases[3][6][8]. There is no single "cytokine/growth factor receptor"—each cytokine or growth factor typically signals via its specific membrane receptor, which then activates intracellular kinase pathways and downstream gene expression[1][7][3]. There are currently numerous therapeutic drugs targeting individual cytokines (like TNF inhibitors, IL-6 inhibitors) or their receptors, and monitoring circulating levels of certain cytokines is important for patient selection and efficacy in clinical settings[6]. This entry is not a valid molecular target per se, but describes a mechanism or pathway involving many molecules. For structured therapeutic targeting and drug development, each distinct cytokine/growth factor (such as "Interleukin-2" or "Vascular endothelial growth factor") or their receptors should be considered as individual canonical targets.
