  • Publication number: 20100215591
    Abstract: The present invention provides antimicrobial peptides that exhibit a broad range of antimicrobial activity to gram positive and gram negative bacteria, as well as fungi, mold, and virus. The antimicrobial peptide of the invention is a cationic peptide, and may contain an HIV-TAT or reverse HIV-TAT sequence, or derivative thereof. The present invention further provides antimicrobial compositions containing the cationic peptide. Such compositions are especially useful for topical application to the skin, hair, nail, vagina, urethra, ear, oral cavity, nasal passage, respiratory system, opthalmic region, and various mucosal regions. The compositions of the present invention improve the condition and/or appearance of the treated region, and are suited for long-term and/or routine use to, for example, prevent or prevent the recurrence of microbial infection. The present invention further provides kits for use in improving the condition or appearance of skin, nail, or treated area.

  • Patent number: 6087341
    Abstract: Skin cells are genetically altered to express a gene product encoded by an introduced polynucleotide. Specifically, the invention involves introduction of a nucleotide of interest into a skin cell by topical application of a polynucleotide that is substantially free of liposomes or charged lipids, where the skin can be either treated or untreated prior to application. Similarly, the invention involves introduction of a nucleotide of interest into a skin cell by topical application of a polynucleotide formulation comprising a liposome or charged lipid, wherein the skin is not treated by removal of hair prior to application. The method of the invention serves as a platform for delivering polynucleotides to skin cells for expression therein for any of a variety uses including, but not limited to genetic immunization.
