CFU-Eos

CFU-Eos (Colony-forming unit-Eosinophil) is a type of stem cell that produces eosinophils, a type of white blood cell. These cells are part of the body's immune system and play a crucial role in the body's response to allergic reactions and parasitic infections.

Overview

CFU-Eos is a type of colony-forming unit (CFU), a term used in hematology to describe a cell that can proliferate and differentiate into mature blood cells. The "Eos" in CFU-Eos stands for eosinophils, indicating that this particular type of CFU gives rise to eosinophils.

Function

CFU-Eos cells are responsible for the production of eosinophils in the bone marrow. Eosinophils are a type of white blood cell that play a key role in the body's immune response. They are particularly important in the body's defense against parasitic infections and in the mediation of allergic reactions.

Clinical significance

Abnormalities in CFU-Eos cells can lead to a number of health conditions. For example, an overproduction of eosinophils, a condition known as eosinophilia, can occur in response to a parasitic infection, certain types of cancer, and some autoimmune diseases. Conversely, a decrease in the number of eosinophils, known as eosinopenia, can occur in response to severe physical or emotional stress, or as a side effect of certain medications.
