Nuclear factor κB inducing factor
View Patent ↗The present invention is directed to nuclear factor κB (NFκB)-inducing factor polypeptides (NFIF polypeptides) which are capable of inducing NFκB. The present invention includes within its scope NFIF polypeptides, including NFIF-14b and NFIF-7a, DNA, including cDNA, encoding these polypeptides, and expression vectors capable of expressing NFIF polypeptides. Also included are methods and compositions for increasing NFκB induction in a patient, methods and compositions for lowering NFκB induction in a patient, methods for inhibiting inflammation, and methods for manufacture of a medicament intended for the treatment and/or prevention of an NFκB-regulated inflammatory response. In addition, methods for determining whether a test compound inhibits or enhances the activity of NFIF polypeptides are provided.
1. An isolated and purified nuclear factor kappa B inducing factor (NFIF) 14b polypeptide which induces nuclear factor kappa B (NFκB) in a patient comprising the amino acid sequence of SEQ ID NO:1.
2. An isolated antibody which specifically binds the NFIF-14b polypeptide of claim 1 .
3. A composition comprising the polypeptide of claim 1 and a pharmaceutically acceptable carrier.
4. A composition comprising the antibody of claim 2 and a pharmaceutically acceptable carrier.
5. The composition of claim 3 , further comprising a biocompatible solution.
6. A method of increasing expression of NFκB in a patient comprising introducing the composition of claim 3 into the body of the patient.
7. A method of inhibiting inflammation comprising administration of the composition of claim 4 to a patient.
8. An isolated and purified NFIF-14b polypeptide which induces NFκB in a patient comprising the amino acid sequence encoded by nucleotides 394 to 1362 of SEQ ID NO: 3.
9. The NFIF-14b polypeptide of claim 8 , further comprising lower NFκB inducing activity than the NFIF-14b polypeptide of claim 1 .
