| Description | Aldesleukin, a lymphokine, is produced by recombinant DNA technology using a genetically engineered E. coli strain containing an analog of the human interleukin-2 gene. Genetic engineering techniques were used to modify the human IL-2 gene, and the resulting expression clone encodes a modified human interleukin-2. This recombinant form differs from native interleukin-2 in the following ways: a) Aldesleukin is not glycosylated because it is derived from E. coli; b) the molecule has no N-terminal alanine; the codon for this amino acid was deleted during the genetic engineering procedure; c) the molecule has serine substituted for cysteine at amino acid position 125. |
| Indication/Disease | For treatment of adults with metastatic renal cell carcinoma. |
| Pharmacodynamics | Aldesleukin is used to treat renal cell carcinoma, it induces the enhancement of lymphocyte mitogenesis and stimulation of long-term growth of human interleukin-2 dependent cell lines, the enhancement of lymphocyte cytotoxicity, the induction of killer cell (lymphokine-activated (LAK) and natural (NK)) activity; and the induction of interferon-gamma production. IL-2 is normally produced by the body, secreted by T cells, and stimulates growth and differentiation of T cell response. It can be used in immunotherapy to treat cancer. It enhances the ability of the immune system to kill tumor cells and may interfere with blood flow to the tumor. |
| Mechanism of Action | Aldesleukin binds to the IL-2 receptor which leads to heterodimerization of the cytoplasmic domains of the IL-2R beta and gamma chains, activation of the tyrosine kinase Jak3, and phosphorylation of tyrosine residues on the IL-2R beta chain. These events led to the creation of an activated receptor complex, to which various cytoplasmic signaling molecules are recruited and become substrates for regulatory enzymes (especially tyrosine kinases) that are associated with the receptor. These events stimulate growth and differentiation of T cells. |
