Methods of use for an antimicrobial peptide
View Patent ↗The present invention encompasses methods for treating an infection and/or treating or reducing inflammation through the administration of a therapeutically effective amount of a peptide to a subject in need thereof. In some aspects, the peptide is a Helicobacter pylori -derived peptide, such as an HPA3NT3 peptide and the infection is a bacterial infection.
1. A method of treating an infection and infection-induced inflammation in non-immortalized cells, the method comprising topically administering a therapeutically effective amount of an HPA3NT3 peptide.
2. The method of claim 1 , wherein the non-immortalized cells are primary cells.
3. The method of claim 1 , wherein the non-immortalized cells are at least one of keratinocytes, dermal microvascular endothelial cells, corneal epithelial cells, and dermal fibroblasts.
4. The method of claim 1 , wherein the infection is a bacterial infection.
5. The method of claim 4 , wherein the bacteria causing the bacterial infection is at least one of Propionibacterium acnes, Staphylococcus aureus , or Pseudomonas aeruginosa.
6. The method of claim 5 , wherein the Pseudomonas aeruginosa bacteria are resistant to more than one antibiotic.
7. The method of claim 6 , wherein the therapeutically effective amount of HPA3NT3 peptide functions as a bactericidal agent.
8. A method of reducing expression of at least one pro-inflammatory cytokine by a non-immortalized cell, the method comprising topically administering a therapeutically effective amount of an HPA3NT3 peptide to the cell.
