Q: How does mavorixafor work?

Mechanism of Action Mavorixafor is a type of medication called a CXCR4 antagonist. It is used to treat WHIM syndrome, a rare genetic disorder where the immune system does not work correctly because white blood cells are not distributed properly throughout the body. The Role of CXCR4 In a healthy body, a protein receptor called CXCR4 helps control how white blood cells move in and out of the bone marrow. In people with WHIM syndrome, a genetic mutation causes this receptor to be overactive. This overactivity acts like a signal that keeps white blood cells trapped inside the bone marrow instead of letting them enter the blood where they are needed to fight germs. Releasing Immune Cells Mavorixafor works by blocking the CXCR4 receptor. By turning off this overactive signal, the medication allows trapped immune cells to move out of the bone marrow and into the bloodstream. The primary cells affected include: Neutrophils: Cells that are essential for fighting bacterial infections. Lymphocytes: Cells that help the body recognize and respond to viruses and other pathogens. By increasing the number of these white blood cells circulating in the blood, mavorixafor helps improve the body's ability to defend itself against recurrent and potentially serious infections.

Question 1

What is mavorixafor?

Accepted Answer

Mavorixafor is a medication known as a CXCR4 antagonist. It works by blocking a specific protein called the CXCR4 receptor, which is involved in how certain white blood cells move and are distributed throughout the body.

By blocking this receptor, the medication helps control the release of these immune cells from the bone marrow into the bloodstream. This process is intended to help maintain healthier levels of white blood cells in circulation to support the immune system.
