Eosínófílir

Eosínófílir, also known as eosinophils, 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 reddish-pink cytoplasm stained with eosin, a basic dye. Eosinophils are part of the innate immune system and are found in small numbers in the blood and tissues of most mammals, including humans.

The primary function of eosinophils is to combat parasitic infections, particularly those caused by helminths, such as worms. They do this by releasing toxic substances and enzymes that can destroy the parasites. Eosinophils also play a role in allergic reactions, where they help to neutralize and remove allergens. In addition, they contribute to the defense against certain types of cancer cells and may have a role in tissue repair and remodeling.

Eosinophils are produced in the bone marrow and circulate in the bloodstream. They can migrate to sites of infection or inflammation, where they become activated and perform their functions. The lifespan of eosinophils is relatively short, typically lasting only a few days in the bloodstream and up to several weeks in tissues.

Eosinophilia, an increase in the number of eosinophils in the blood, can be a sign of various conditions, including parasitic infections, allergic disorders, and certain types of cancer. Conversely, a decrease in eosinophils, known as hypereosinophilia, can also indicate underlying health issues. Eosinophils are a vital component of the immune system, and their proper functioning is essential for maintaining overall health.
