Anti-Interleukin-2 (IL-2) Antibody, clone 3F9

Interleukin-2 (IL-2) is commonly considered a pro-inflammatory cytokine that stimulated T-cell-dependent immune reactions and control regulatory T cells or Tregs. Structurally, IL-2 is thought to have a 4-helix-bundle-type fold and uses a novel type I cytokine receptor (IL-21R) with the common gamma chain cytokine receptor. IL-2 also may intensify Th1-mediated diseases, including autoimmune arthritis and may also be interesting clinical targets for those diseases. IL-2 has also been implicated as a possible therapy for infection and cancer. Anti-tumor therapies that include a combination of recombinant IL-2 and recombinant interferon alpha have been promising in clinical studies.
