Learn About Agranulocytosis

What is the definition of Agranulocytosis?

White blood cells fight infections from bacteria, viruses, fungi, and other germs. One important type of white blood cell is the granulocyte, which is made in the bone marrow and travels in the blood throughout the body. Granulocytes sense infections, gather at sites of infection, and destroy the germs.

When the body has too few granulocytes, the condition is called agranulocytosis. This makes it harder for the body to fight off germs. As a result, the person is more likely to get sick from infections.

What are the latest Agranulocytosis Clinical Trials?
A Phase I Study of MozobilTM in the Treatment of Patients With WHIMS

Background: WHIMS (Warts, Hypogammaglobulinemia, Infections, and Myelokathexis Syndrome) is caused by various genetic changes that increase the activity of the chemokine receptor, CXCR4. Excessive function of this receptor causes mature neutrophils (part of the white blood cells) to be retained within the bone marrow rather than being released to the blood and is one of the causes of severe inherited neutrope...
