Peptides for blocking IL1RAP protein-protein interaction and uses thereof for treatment of disease
Methods and agents are provided for inhibiting interleukin 1 receptor accessory protein (IL1RAP) protein-protein interaction to treat a broad spectrum of diseases and conditions.
1. A method of treating a disease or condition in a subject, to inhibit interleukin 1 receptor accessory protein (IL1RAP) interaction with interleukin 1 receptor 1 (IL1R1) or interleukin 1 receptor 2 (IL1R2), the method comprising administering to the subject an agent comprising a peptide in an amount effective to inhibit IL1RAP interaction with IL1R1 or IL1R2, wherein the peptide has 18-30 amino acids and comprises the amino acid sequence set forth in SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:6 or SEQ ID NO:7, wherein the disease or condition is chronic myeloid leukemia (CML), acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), asthma, allergy, anaphylaxis, cardiovascular disease, or arthritis.
2. The method of claim 1 , wherein the peptide consists of the amino acid sequence set forth in SEQ ID NO: 1 or SEQ ID NO:2.
3. The method of claim 1 , wherein the peptide is a synthetic peptide.
4. The method of claim 1 , wherein the peptide is conjugated to a cytotoxic agent, a polyethylene glycol (PEG) or a nanoparticle.
