Abstract
Liposomal and/or nano-liposomal encapsulated HSP90a, HPf polypeptide (115 aa) and novel polypeptides HPf ΔC1 (101 aa) and HPfΔC2 (87 aa), as well as methods for manufacturing/preparing and using the compositions, are disclosed. Chimeric fusion proteins that include an HSP90a, HPf-polypeptide, HPf ΔC1 or HPfΔC2 polypeptide are presented. Transformed cell lines and expression vectors capable of expressing the chimeric fusion proteins, are provided. Methods for producing large amounts of recombinant HSP90a, HPf polypeptide, HPf ΔC1 or HPfΔC2 polypeptide, using expression vectors and transformed cell lines, are described. Topical and other delivery form preparations and methods for using the preparations, including methods for improving skin conditions (atopic dermatitis, wrinkles, skin elasticity, dark spots (over pigmentation), overall skin rejuvenation, skin ageing) for therapeutic and cosmeceutical uses are presented. Liposomal preparations and methods for using them for enhancing wound healing and methods for suppressing subcutaneous fat cell differentiation and reducing subcutaneous fat formation are disclosed.
