Interleukin II (60-70) is an 11-amino-acid peptide fragment corresponding to residues 60–70 of the human Interleukin-2 (IL-2) cytokine, a key regulator of T-cell activation and immune responses. Derived from the primary structure of IL-2, this segment is located within a critical domain involved in binding to the IL-2 receptor (IL-2R) complex, particularly interacting with the β and γ subunits to initiate signaling pathways that drive T-cell proliferation, differentiation, and cytokine production. In pharmacological research, Interleukin II (60-70) serves as a tool to investigate IL-2 receptor recognition mechanisms, structure-activity relationships, and the development of targeted immunomodulators. It supports studies on T-cell-mediated immunity, cancer immunotherapy (e.g., enhancing adoptive T-cell therapies), and autoimmune disorders, offering insights into how specific peptide regions modulate IL-2 signaling for therapeutic applications.
