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 NFIF-7a polypeptide which induces NFκB in a patient comprising the amino acid sequence of SEQ ID NO:2.
2. A composition comprising the polypeptide of claim 1 and a pharmaceutically acceptable carrier.
3. The composition of claim 2 , further comprising a biocompatible solution.
4. A method of increasing expression of NFκB in a patient comprising introducing the composition of claim 2 into the body of the patient.
5. A method of inhibiting inflammation comprising administration of the composition of claim 2 to a patient.
6. An isolated and purified NFIF-7a polypeptide which induces NFκB in a patient comprising the amino acid sequence encoded by nucleotides 394 to 1095 of SEQ ID NO: 4.
