Metabolic Profiling of Immune Responses in Immune-mediated Diseases

Background: The immune system is the part of the body that fights infection. Some people have immune deficiencies that cause skin rashes, make them get sick often with infections, or make it difficult for their skin to heal. Researchers want to learn more to better treat conditions that affect immune response. Objective: To learn about how the immune system and skin healing are related to each other. Eligibility: People ages 18-75 with primary immune deficiency, eczema, or psoriasis. Healthy volunteers are also needed. Design: Participants will be screened with a medical and medicine history and a physical exam. They may take a pregnancy test. Participants will discuss the medicines or supplements they take as well as skin products they use, such as soaps and lotions. Participants will have up to 4 skin biopsies taken from the forearm. A needle will inject an anesthetic into the skin where the biopsy will be done. A sharp tool that looks like a tiny cookie cutter will be used to remove a round plug of skin a bit smaller than the tip of a pencil. Participants will give at least 1 blood sample. Participants may have optional skin swab collection. A cotton swab will be used to swab the skin on the arm. Participants may have optional skin tape collection. A sticky strip of tape will be placed on the arm and then removed. Participants may give leftover samples taken as part of their regular medical care. Participation will last for about 4 days. Participants will hav…
