Study of how certain immune cells use a nutrient

This study uses a special label (carbon 13) to track bone marrow cells in people with a pre-cancer condition called MGUS. It aims to learn how these cells work, which may help understand the condition better.

This study measures how your body’s metabolism works in people with chronic lymphocytic leukemia (CLL). It uses blood tests, and for some people, a bone marrow sample, to better understand what’s happening and potentially guide future treatments.

This study tests improved ways to select and collect bone marrow cells from healthy donors for use in transplants. Researchers are looking for healthy volunteers to donate cells that may help people who need bone marrow transplants.

This study looks at how blood cancer cells use energy (metabolism) and how that affects the immune system. Researchers hope to find new ways to treat these cancers by understanding cell metabolism better.

This Phase 1/2 study tests whether transfusions of donated plasma can improve frailty and immune function in older adults. It mainly checks safety first, and also looks for signs that the immune system and overall strength may improve.

This study collects blood-forming cells from people with low CD4 counts and healthy volunteers to learn how the immune system works. It may help researchers better understand and treat conditions like idiopathic CD4 lymphocytopenia.
