A cosmetic method for modulating pigmentation in a subject includes administering a modulator of angiotensin-converting enzyme 2 (ACE2 modulator) to the subject. The ACE2 modulator can be an inhibitor of angiotensin-converting enzyme 2 (ACE2 inhibitor), in which case, the ACE2 inhibitor can be administered to increase pigmentation in the subject. The ACE2 modulator can also be an activator of angiotensin-converting enzyme 2 (ACE2 activator), in which case the ACE2 activator can be administered to decrease pigmentation in the subject. The treatment of inflammatory skin disease can also be achieved by inhibition of angiotensin-converting enzyme 2.

Treatments for synucleinopathy including Parkinson's Disease (PD), Multiple System Atrophy (MSA), and Dementia with Lewy Bodies (DLB) are largely unavailable. The invention provides methods for treating, preventing, inhibiting, and reversing synucleinopathy by attenuating MSH activity, decreasing MSH expression, or by modulating MSH engagement with its receptor by utilizing antagonists. Furthermore, the inventor has provided a method for producing a synucleinopathy animal model for screening treatments and for studying synuclein disease pathology.

The present disclosure relates to, among other things, compounds and methods for treating neuropathic pain, ocular pain, ocular inflammation, and/or dry eye and methods of detecting mutations in specific G-protein coupled receptors, such as missense mutations, and determining the extent to which these mutations alter the pharmacological response of the G-protein coupled receptor.
