Abstract

Cytokines, as molecular messengers of the immune system, play pivotal roles in regulating immune responses and maintaining immune homeostasis. Understanding the intricate language of cytokine signaling is essential for deciphering disease pathogenesis, designing effective therapies, and developing vaccines. Cytokine assays serve as indispensable tools in immunology, enabling the quantification and characterization of cytokine levels in biological samples. This abstract explores the significance of cytokine assays in unraveling the complexities of immune responses. It highlights the diverse methodologies employed for cytokine analysis, including Enzyme- Linked Immunosorbent Assay (ELISA), multiplex immunoassays, flow cytometry-based assays, Reverse Transcription Polymerase Chain Reaction (RT-PCR), and Bio-Plex assays. The applications of cytokine assays in biomarker discovery, immunotherapy monitoring, infectious disease research, and autoimmune disease studies are discussed. Despite challenges in standardization and variability, cytokine assays hold immense promise for advancing our understanding of immune regulation and guiding personalized approaches to disease management.
