Lumbar puncture (spinal tap)

A procedure that takes a sample of cerebrospinal fluid (liquid that surrounds the brain and spinal cord). This is done by inserting a needle between two vertebrae (bones in the spine).

Lymphocytes

White blood cells that play an important role in the immune system. There are three types: B cells, T cells and Natural Killer (NK) cells.

Lymphodepleting chemotherapy

Chemotherapy given before CAR-T cell infusion in order to decrease the number of white blood cells (including T cells) in the body. CAR T cells grow and expand better if there are not as many of the patient’s own T-cells present.
