Background:

- Laboratory research studies require control samples from healthy volunteers to compare with samples from patients. These studies will help researchers better understand and refine treatments for immune system and inflammatory diseases.

Objective:

- To obtain blood, urine, buccal (mouth) mucosa, normal tissue and bone marrow samples and/or leukopheresis cells from healthy volunteers.

Eligibility:

- Healthy individuals at least 8 years of age.

Design:

• Volunteers will be recruited through the Program for Healthy Volunteers, Patient Recruitment and Public Liaison Office, or self-referral through the clinicaltrials.gov Web site.
• Health will be confirmed by a brief history and physical examination and blood work.
• Volunteers 8 years of age and older will provide blood and urine samples using standard procedures. Buccal mucosa samples will be obtained by scraping the insides of both cheeks with a sterile nylon brush.
• Bone marrow samples will be obtained from volunteers 18 years of age and older by taking two aspirates from the posterior iliac crest (an area near the hip).
• Normal tissue samples will be obtained from volunteers 18 years of age and older by taking superficial skin samples (punch biopsies)
• Leukopheresis or lymphapheresis will be performed on volunteers 18 years of age and older to obtain white blood cells for research
• Samples will be assigned a unique code and will be stored until they are no longer of scientific value or the volunteer withdraws consent for their use.

The purpose of this protocol is to collect blood (ages 8 and older), urine (ages 8 and older), buccal mucosa samples (ages 8 and older), normal tissue (ages18 and older) bone marrow (ages 18 and older) and/or leukapheresis cells (ages 18 and older) from healthy volunteers, including pregnant women (ages 18 and older, blood and/or buccal mucosa only). To be enrolled on this study, pregnant women must not carry the diagnosis of an immune-mediated or inflammatory disease, or have signs or symptoms of an immune or inflammatory disease; otherwise they may be eligible for participation on CHI protocol 10-H-0162 in the affected adult cohort. Samples will be used as controls for clinical and translational research in the Center for Human Immunology, Autoimmunity, and Inflammatory Diseases (CHI). These control samples are indispensable for many of our laboratory research projects, including understanding the pathophysiology of a wide variety of immune-mediated and inflammatory diseases.

The primary objective is to provide a mechanism for collection, tracking, storing, dispensing, analyzing and disposing of these laboratory research samples from healthy volunteers.

There is no primary endpoint.

• INCLUSION CRITERIA:
• Healthy volunteer (health status confirmed by brief History and Physical Exam and blood work)
