Provided herein are nanofibres including self-assembled cellular components derived from a homogenized plant tissue. Methods for preparing such nanofibres, as well as uses thereof in the treatment or prevention of diseases or disorders in a subject and/or as delivery vehicles are also described.

A polypeptide conjugate for use in a method for binding and/or internalization of the polypeptide conjugate to a mammalian cell having a transferrin receptor (TFRC) and/or receptor for advanced glycation end products (RAGE). The polypeptide conjugate may be used in a method for targeting of a drug delivery system or diagnostic delivery system.

Corticosteroid compositions including a corticosteroid drug substance (e.g., fluocinolone, fluocinolone acetonide, dexamethasone, dexamethasone phosphate, dexamethasone sodium phosphate, triamcinolone, and triamcinolone acetonide) or a or a salt or derivative thereof and one or more irregular-shaped particulate fatty acid or keto-enol tautomer complexation agents admixed in a dispersal medium, having a release profile with one or more phases of drug release. These compositions are extended release corticosteroid compositions may release a clinically useful level of corticosteroid for more than 1 to 12 months within the body. Also described herein are methods of forming and methods of using these compositions.
