Identification and Analysis of Immunomodulatory Molecules in Patients With Hematologic Disorders and Healthy Volunteers

This research study goal is to analyze the plasma and the cells that make up part of the
immune system. These cells, called white cells or leukocytes, are present in blood. We want
to learn how these cells work to prevent infection and how they respond after an infection
occurs. We also want to study certain molecules present on the plasma, on or in these cells,
and the genetic material that allows these molecules to be made. These molecules may
influence why one person will develop an infection and another will not, or why one person
develops severe symptoms of a disease while others remain without symptoms. This study may
increase our understanding of a variety of diseases including infections such as HIV,
allergic diseases such as asthma, joint diseases such as rheumatoid arthritis, certain
cancers, and the rejection process that sometimes occurs after transplantation of an organ.

Inclusion Criteria:

- Must be able to give blood

- Must be able to give informed consent

- Signed, written informed consent

Exclusion Criteria:

- Individuals with a history severe anemia, inadequate venous access, severe blood or
coagulation disorders.

- Pregnant women are excluded because it is a unique immunotolerant state and will alter
the profile of immunomodulatory molecules.
