NCIt definition : A polyethylene glycol (PEG)-conjugated form of the cytokine interleukin-2 (IL-2),
with potential immunopotentiating and antineoplastic activities. Upon administration,
pegylated IL-2 8MW2311 activates the Janus kinase/signal transducers and activators
of transcription (JAK/STAT) signaling pathway. This induces the proliferation of CD8
T-cells, enhances tumor cell killing and decreases tumor cell proliferation. Pegylation
of IL-2 protects the cytokine from degradation.;
