What lymphocytes mean?
Lymphocytes are white blood cells and one of the body’s main types of immune cells. They are made in the bone marrow and found in the blood and lymph tissue. The immune system is a complex network of cells known as immune cells that include lymphocytes.
What is meant by reactive lymphocytes?
Reactive lymphocytes are immune-stimulated lymphocytes with upregulated synthesis of inflammatory mediators, and/or immunoglobulins (antibodies), or both. Reactive lymphocytes in peripheral blood suggest active, systemic antigenic stimulation secondary to both infectious and noninfectious disorders.
What causes reactive lymphocyte?
Causes. Reactive lymphocytes are usually associated with viral illnesses, but they can also be present as a result of drug reactions (such as phenytoin), immunizations, radiation, and hormonal causes (such as stress and Addison’s disease), as well as some autoimmune disorders (such as rheumatoid arthritis).
What does small mature lymphocytes mean?
Small lymphocytic lymphoma (SLL) is a cancer that affects a type of white blood cell called a “lymphocyte,” which helps your body fight infection. You may hear your doctor refer to SLL as a “non-Hodgkin’s lymphoma,” which is a group of cancers that affect lymphocytes.
What viruses cause high lymphocytes?

What is a good lymphocyte count?
A normal lymphocyte count for adults usually is between 1,000 and 4,800 lymphocytes per microliter of blood. For children, a normal lymphocyte count usually is between 3,000 and 9,500 lymphocytes per microliter of blood.
What are the 2 main types of lymphocytes?

What does peripheral lymphocytes mean?
Peripheral blood smear. A population of mantle cells with a cleaved nucleus and paucity of cytoplasm Lymphocytes are white blood cells that serve primarily as the body’s adaptive immune system and provide humoral or cell-mediated immunity against a variety of bacterial, viral, or other pathogens.
What does cleaved angulated lymphocytes mean?
Lymphocytes that are cleaved angulated, or have indented nuclei can be associated with pertussis or malignancies such as follicular lymphoma. “Hairy cells” with regular cytoplasmic projections are seen in hairy cell leukemia Sezary Cells have cribriform nuclei with compact chromatin “Villous” lymphocytes are seen in MZL
What is the difference between T cells and lymphocytes?
The T cells destroy the body’s own cells that have themselves been taken over by viruses or become cancerous. Lymphocytes are cells that circulate in your blood that are part of the immune system. There are two main types lymphocytes: T cells and B cells.
