Steps and methodology of skin biopsy processing for dSTORM. (A) Skin biopsy taken from the upper back (C7). (B) The skin contains various innervated structures, such as erector pili muscles, sweat glands, autonomic nerves, and cutaneous nerves. (C,D) Confocal image of a sweat gland from PD patient: p-aSyn (red), neuronal marker PGP9.5 (green) and areas of co-localization (yellow). (E) dSTORM reconstructed image of part of the sweat gland innervation (insert in D) shows p-aSyn (red) and PGP9.5 (green) and their co-localization (yellow). Insert-a close-up view showing single-molecule distribution of both p-aSyn (red) and PGP9.5 (green).
