This scanning electron microscopy image captures the moment where degranulating mast cells (pseudo-colored in sepia) attract and start to incorporate living neutrophils (pseudo-colored in cyan), ...

Mast cell leukemia (MCL) is a quick-progressing condition that leads to the buildup of mast cells in your bone marrow and other tissues. It falls into a group of diseases collectively known as ...

Mast cell activation syndrome, or disease (MCAS), is a condition that causes mast cells to release these substances too frequently, resulting in severe allergic reactions. After detecting an allergen, ...

A rare set of immune diseases called clonal mast cell activation disorders (cMCADs) may be associated with strong immunity to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is ...

Mast cell leukemia (MCL) is a rare type of blood cell cancer. It causes the body to produce a large number of mast cells that can affect different areas of the body. MCL is a subtype of mastocytosis.

The itching, redness and swelling of an allergic reaction are caused by mast cells—the vigilant first responders of the immune system that spring into action with histamine-filled granules in response ...

In a recent study published in Nature, researchers used a mouse model to show that mast cells and immunoglobulin E (IgE) are the key orchestrators of antigen-specific avoidance, a behavioral ...

For many patients with diverse and seemingly unrelated symptoms, obtaining an accurate diagnosis can take years of specialist visits and inconclusive tests. Mast cell activation syndrome, a disorder ...

Mast cell tumors (MCTs) are the second most common skin tumor in cats. Feline mast cell tumors are commonly found in the head, neck, and limbs. If your cat has cutaneous mast cell tumors, it can ...

Mast cell activation syndrome is a condition that causes mast cells to release an inappropriate amount of chemicals into your body. This causes allergy symptoms and a wide range of other symptoms.
