Abstract:

Interleukin-2 (IL-2), the first successfully cloned cytokine derived from multicellular sources, is a multifunctional molecule primarily produced by CD4+ T cells.It plays a crucial regulatory role in multiple lymphocyte lineages, making it a promising therapeutic option for immune-mediated diseases.The transcriptional regulation of endogenous IL-2 involves various cis-acting elements and trans-acting factors,with the IL-2 gene promoter playing a vital role.This paper reviews the latest developments in engineered IL-2 research, and explores the molecular mechanisms regulating IL-2 transcription.It covers the expression distribution, expression patterns, epigenetic modifications of the IL-2 gene, and the diverse trans-acting factors that interact with its promoter.These insights are vital for optimizing IL-2-based therapeutic strategies and developing novel immunotherapies with higher target cell selectivity, extended half-life, enhanced stability, minimized side effects and immunogenicity, and expanded therapeutic applications.

Key words: Interleukin-2, Cis-acting elements, Trans-acting factors, Transcriptional regulation
