Basophils are a type of white blood cell that plays a crucial role in the immune response. They are characterized by their large, bilobed nucleus and abundant cytoplasmic granules. Basophils are relatively rare, making up about 0.5% to 1% of all white blood cells in the human body. They are found in the bloodstream and tissues, where they help to defend the body against infections and other threats.

Basophils are involved in both the innate and adaptive immune responses. In the innate immune response, they release histamine and other mediators in response to injury or infection, which can cause vasodilation, increased vascular permeability, and inflammation. This helps to attract other immune cells to the site of infection and aids in the clearance of pathogens.

In the adaptive immune response, basophils can produce and release cytokines, such as interleukin-4 (IL-4) and interleukin-13 (IL-13), which help to regulate the activity of other immune cells, including T cells and mast cells. These cytokines play a key role in the development and function of allergic responses and the regulation of immune cell activity.

Basophils can also produce and release heparin, a substance that has anticoagulant properties. This helps to prevent blood clotting at the site of infection, which can interfere with the immune response.

Basophils are typically identified and counted using flow cytometry or other specialized laboratory techniques. Abnormal levels of basophils in the blood can be indicative of certain conditions, such as allergic disorders, parasitic infections, or certain types of cancer. However, the significance of basophil levels should be interpreted by a healthcare professional in the context of the individual's overall health and medical history.
