Patent attributes
Compositions and methods for treating hair loss are provided. One embodiment provides a microneedle composition, which when administered to the skin of a subject promotes hair growth. The microneedle compositions include an effective amount of glucocorticoid-induced leucine zipper (GILZ) protein having an amino acid sequence that has 99 or 100% identity to SEQ ID NO: 1, or fragment thereof to promote hair growth when administered to the skin of the subject and a bioerodible, biodegradable, or biosorbable polymer, wherein the composition is formulated as bioerodible, biodegradable, or bioabsorbable microneedles. In one embodiment the GILZ protein or fragment thereof is conjugated to a cell penetrating peptide. The cell penetrating peptide can be TAT GRKKRRQRRRPQ (SEQ ID NO:4) or a variant thereof.
