The history of cytokines and growth factors development

Abstract

The discovery and development of cytokines and growth factors represent transformative events in modern medicine, spanning from early observations of immune mediators to current therapeutic applications. This review chronicles the historical progression from the initial identification of permeability factors in 1926 to contemporary engineered cytokine therapeutics. Key milestones include the discovery of interferon (1957), the characterization of colony-stimulating factors, and the development of recombinant proteins in the 1980s. The field has evolved from basic understanding of immune communication to sophisticated therapeutic interventions, including targeted inhibitors and engineered cell therapies. While significant advances have been made in treating various diseases through cytokine modulation, challenges remain in managing pleiotropic effects and optimizing delivery systems. Recent innovations in bioengineering and cell therapy suggest promising directions for future therapeutic applications.
