Elucidating the Fundamental Differences Between HLA-Cw6 Positive and HLA-Cw6 Negative Psoriasis Skin Lesions, With a Comparison to Healthy Skin, at the Single Cell Level of the Infiltrated Immune Cell Types
The purpose of this study is to understand how genetics play a role in psoriasis.
Specifically, a genetic allele HLA-Cw6 is known to be associated with psoriasis, and this
study aims to find out how it affects genetic and protein expression in patients with
psoriasis, compared to healthy people, at a single-cell level using a novel flow cytometry
and RNA-sequencing protocol.

1. Ability to provide written consent and comply with the protocol
2. At least 18 years of age
3. Diagnosis of plaque psoriasis for at least 6 months prior to enrollment
4. BSA > 5% and at least one target plaque on trunk or extremities greater than 10cm2
For control subjects:
1. Ability to provide written consent and comply with the protocol
2. At least 18 years of age
3. No previous diagnosis of psoriasis or other inflammatory skin conditions
Exclusion Criteria:
For subjects in the psoriasis group:
1. Subject has non-plaque form of psoriasis.
2. Subject has drug-induced psoriasis.
3. Pregnancy at any point during the study period.
4. Known allergy to lidocaine, other local anesthetics, or any component of local
anesthetic agents.
5. Known HIV positive status.
6. Evidence of abnormality of any immune cell population from a drug-induced or genetic
cause.
7. Known coagulopathy.
For control subjects:
1. Any physical examination findings by the investigators consistent with psoriasis or
other inflammatory skin conditions.
2. Pregnancy at any point during the study period.
3. Known allergy to lidocaine, other local anesthetics, or any component of local
anesthetic agents.
4. Known HIV positive status.
5. Evidence of abnormality of any immune cell population from a drug-induced or genetic
cause.
6. Known coagulopathy.
7. Use of any immunosuppressant or immunomodulating therapies within 6 months.
