Summary for Patent: 5,877,021

Title:	B7-1 targeted ribozymes
Abstract:	Nucleic acid molecule which blocks synthesis and/or expression of an mRNA encoding B7-1.
Inventor(s):	Stinchcomb; Dan T. (Boulder, CO), Jarvis; Thale (Boulder, CO), McSwiggen; James (Boulder, CO)
Assignee:	Ribozyme Pharmaceuticals, Inc. (Boulder, CO)
Application Number:	08/585,684
Patent Claims:	1. An enzymatic nucleic acid molecule which specifically blocks synthesis and/or expression of an mRNA encoding B7-1. 2. The enzymatic nucleic acid molecule of claim 1, wherein, the binding arms of said enzymatic nucleic acid molecule comprise sequences complementary to any of sequences defined as Seq ID Nos 1-299 and 599-896. 3. The enzymatic nucleic acid molecule of claim 1, wherein said enzymatic nucleic acid molecule is in a hammerhead motif. 4. The enzymatic nucleic acid molecule of claim 1, wherein said enzymatic nucleic acid molecule is in a hairpin, hepatitis Delta virus, group I intron, VS nucleic acid or RNaseP nucleic acid motif. 5. The enzymatic nucleic acid molecule of any of claim 1, wherein said enzymatic nucleic acid molecule comprises between 12 and 100 bases complementary to the RNA of said region. 6. The enzymatic nucleic acid of claim 5, wherein said enzymatic nucleic acid molecule comprises between 14 and 24 bases complementary to the RNA of said region. 7. A mammalian cell including an enzymatic nucleic acid molecule of claim 1. 8. The mammalian cell of claim 7, wherein said mammalian cell is a human cell. 9. An expression vector comprising a nucleic acid sequence encoding the enzymatic nucleic acid molecule of claim 1, in a manner which allows expression and/or delivery of that enzymatic RNA molecule within a mammalian cell. 10. A mammalian cell including the expression vector of claim 9. 11. The mammalian cell of claim 10, wherein said mammalian cell is a human cell.
