Abstract

Some embodiments of the present disclosure relate to one or more compositions that upregulate the production of one or more sequences of micro-interfering ribonucleic acid (miRNA). The miRNA may be complimentary to a sequence of target messenger RNA (mRNA) that encodes for a target biomolecule and the miRNA can cause the target mRNA to be degraded or inactivated, decreasing the bioavailability of the target biomolecule within a subject that is administered the one or more compositions. In some embodiments of the present disclosure, the target biomolecule is a complement or a factor. In some embodiments of the present disclosure, the target biomolecule is a complement such as complement C1q, complement C1r, complement C1s, complement C3 or complement C5. In some embodiments of the present disclosure, the target biomolecule is a factor such as Factor B, Factor D or Factor 10.

Claims (3)

1 . A composition that comprises a recombinant plasmid (RP) comprising a sequence of nucleotides that is SEQ ID NO. 2.

2 . The composition of claim 1 , wherein the RP is encased in a protein coat, a lipid vesicle, or any combination thereof.

3 . A composition that comprises a recombinant plasmid (RP) comprising a sequence of nucleotides that is SEQ ID NO. 10.
