Abstract

Abstract A method for treating cutaneous and corneal wounds as well as certain microbial-related diseases comprises topically applying a defensin peptide to the affected tissue. The compositions comprise a natural, synthetic, or analog defensin molecule having both a mitogenic activity capable of stimulating cell growth and an antimicrobial activity capable of inhibiting the growth of a wide variety of pathogens. In addition to therapeutic use, the defensins are useful as mitogens in cell and tissue culture media.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 31 words
A method for treating wounds in mammalian tissue to promote healing, said method comprising applying a defensin peptide to the wound in an amount sufficient to promote healing of the wound.
Claim 2
Independent Claim 31 words
A method for treating wounds in mammalian tissue to promote healing, said method comprising applying a defensin peptide to the wound in an amount sufficient to promote healing of the wound.
Claim 3
Dependent Claim 17 words
A method as in claim 1, wherein the defensin peptide is applied to a corneal epithelial wound.
Claim 4
Dependent Claim 19 words
A method as in claim 2, wherein the defensin peptide is applied to a corneal epithelial or stromal wound.
Claim 5
Dependent Claim 29 words
A method as in claim 2, wherein the defensin peptide is present in a physiologically-acceptable carrier at a concentration in the range from about 1 nM to 10 mM.
Claim 6
Dependent Claim 31 words
A method as in claim 2, wherein the defensin peptide is selected from the group consisting of HNP-1, HNP-2, HNP-3, HNP-4, NP-1, NP-2, NP-3A, NP-3B, NP-4, RatNP-1, RatNP-2, RatNP-4, and GPNP.
Claim 7
Independent Claim 30 words
A method for treating corneal wounds and keratitis, said method comprising applying a defensin peptide to the eye of an affected host in an amount sufficient to effect said treating.
Claim 8
Independent Claim 30 words
A method for treating corneal wounds and keratitis, said method comprising applying a defensin peptide to the eye of an affected host in an amount sufficient to effect said treating.
Claim 9
Dependent Claim 17 words
