The lymphocytes correspond to a specific family of white blood cells (or leucocytes) present in the blood.
What are they for ? Why are they so important? And what does it mean to increase or decrease lymphocytes? We explain everything!
What are the lymphocytes for?
These blood cells, which belong to the family of white blood cells, play a major role in the body's immune defense system.
These lymphocytes circulate in the blood, they are made in the bone (bone marrow), and are also found in various organs such as the spleen, the ganglia, the thymus ...Lymphocytes account for about 30% of leukocytes. They play complementary roles compared to other populations of white blood cells: neutrophils, oesinophils, basophils, monocytes, macrophages, etc.
In fact there are two large families of lymphocytes with each of the very specific functions: B and T lymphocytes.
- B cells secrete antibodies, immunoglobulins.
- T cells act directly against the target antigens.
Among the T lymphocytes, some have specific properties, as clearly evoked by the name "killer cell".
To know the number of lymphocytes, it is sufficient to take a blood test. The doctor prescribes: a blood count (NFS). If the number of lymphocytes varies, and out of the normal, it will be necessary to know if this variation is episodic ... or if it remains.You want to react, to give your testimony or to ask a question?
