Abstract

The cytokine network is the central regulatory system for intercellular communication within the immune system. Its proper function depends on the dynamic balance between pro-inflammatory and anti-inflammatory cytokines. Through complex positive and negative feedback loops, this balance precisely regulates the intensity and duration of immune responses, thereby playing a critical role in both physiological and pathological states. This review systematically summarizes the compositional features and classification framework of the cytokine network, as well as the mechanisms by which it maintains homeostasis under physiological conditions. It further examines the manifestations of cytokine network imbalance in diseases such as sepsis, psoriasis, rheumatoid arthritis, inflammatory bowel disease, and cancer. Available evidence suggests that these imbalances drive disease onset and progression primarily through cascade amplification of pro-inflammatory signaling, insufficient generation of anti-inflammatory signals, and aberrant epigenetic modification. These pathological changes are strongly influenced by factors such as infection, autoimmune dysregulation, and the tumor microenvironment (TME), together constituting the core pathological axis of “cytokine imbalance-immune dysregulation-disease progression.” This review also summarizes current clinical strategies targeting the cytokine network, including monoclonal antibodies, Janus kinase (JAK) inhibitors, and emerging modalities such as bispecific antibodies and chimeric antigen receptor (CAR) cell therapy. In addition, it evaluates the clinical efficacy, potential risks, and future directions of these approaches. In summary, a deeper understanding of the binary balance within the cytokine network not only broadens our knowledge of immune regulation but also provides a theoretical basis and translational framework for the development of precision immune-targeted therapies.
