There are three types of lymphocytes. The two main types are B cells and T cells. The third is the NK, or natural killer cell. This is a brief explanation of their function:
What are the potential complications of low or high lymphocyte counts?
In cases of lymphocytosis, an excess number of circulating lymphocytes could lead to rupture of the spleen, reduced levels of gamma globulin to fight infection, and leukostasis ( sluggish blood flow), which could cause stroke, myocardial infarction, and loss of vision.

For example, medical professionals treat infections with antimicrobials and cancers with chemotherapy, radiation therapy, surgery, or targeted therapies. Lymphocyte counts should return to the normal range after treatment.
How many white blood cells are there in the human body?
For every 600 to 700 red blood cells, you have one white blood cell. They may be fewer, but they’re mighty. They act like your body’s army. They’re dispersed throughout your body, but once an organism or virus invades, they immediately gather to fight it off. Lymphocytes are formed in your bone marrow.

Why do lymphocytes develop memory cells?
After an encounter with an antigen, some lymphocytes develop into memory cells. When these memory lymphocytes meet an antigen for a second time, they respond rapidly and specifically to this antigen. This is why vaccines can prevent certain disorders.
What type of lymphocytes are able to destroy tumor cells without any prior activation?
There is also another type of lymphocyte called natural killer cells. These natural killer cells are able to destroy tumor cells without any prior activation. This is unlike the T cells which need to be activated by another immune cell.

A low lymphocyte count, called lymphocytopenia, usually occurs because: your body isn’t producing enough lymphocytes. lymphocytes are being destroyed. lymphocytes are trapped in your spleen or lymph nodes. Lymphocytopenia can point to a number of conditions and diseases.
What is the lymphatic system?
The lymphatic system is the group of tissues and organs, like the spleen, tonsils, and lymph nodes, that protect your body from infection ( 1 ). About 25 percent of the new lymphocytes remain in the bone marrow and become B cells. The other 75 percent travel to your thymus and become T cells ( 2. ).
Why are white blood cells important?
White blood cells are an important part of your immune system. They help your body fight antigens, which are bacteria, viruses, and other toxins that make you sick. If your doctor says you have a weakened immune system, that means there aren’t enough white blood cells in your bloodstream ( 1 ).
Which cells fight infection?
memory cells that have been in your body long enough to recognize and “remember” past infections and go into action quickly if you become re-infected with an antigen. B lymphocytes and T lymphocytes work together to fight infection.
What are the three types of lymphocytes?
So called because they are the primary type of cell found in lymph, lymphocytes have three major types: T cells, B cells, and natural killer cells. Together, lymphocytes are the major component of our body’s adaptive immune response and usually account for approximately 20%-40% of the total white blood cells circulating at a given time.
What is the optimal result for a lymphocyte test?
Optimal Result: 20 - 40 %. Lymphocytes are cells that work in our immune system and thus belong to the white blood cell family. Lymphocytes, neutrophils, monocytes, eosinophils, and basophils levels are assessed through a blood differential test (also called a white blood cell differential), as a part of a complete blood count.
What does it mean when your lymphocytes are low?
Known as lymphocytopenia, decreased lymphocyte levels may indicate: - An autoimmune disorder like lupus. - Bone marrow damage (e.g., chemotherapy, radiation treatment) - An infection like HIV or hepatitis. - A severe infection, such as sepsis, which is wiping out white blood cells faster than the body an make them.

What does a lymphocyte look like?
Recognizing Lymphocytes. Human RBCs lack a nucleus, while lymphocytes look like they're almost entirely composed of the nucleus—like a fried egg that's almost-all yolk. With the proper stain, the nucleus is dark purple, while the surrounding cytoplasm is lighter pink.
What are the cells that fight infection?
Lymphocytes are cells of the immune system and help fight infection. Lymphocytes live in lymph nodes, but also in the bloodstream and all over the body. Lymphocytes come in two main types: B-cells and T-cells. Abnormal numbers of lymphocytes in the blood may be temporary or long-term.
What is the nucleus of a lymphocyte?
Also, lymphocytes are almost entirely composed of a nucleus, which is a DNA - storing structure located in the middle of the cell. With the proper stain, the nucleus of a lymphocyte is dark purple, while the surrounding jelly-like fluid—what's known as cytoplasm—is lighter pink.

T lymphocytes. There are a number of different T lymphocytes: Helper T cells release a protein called cytokines which help to further direct the response of other white blood cells . Cytotoxic T cells (also known as natural killer T cells) are able to release molecules which kill viruses and other antigens. Memory T cells will be present ...
Which type of lymphocytes release antibodies?
B lymphocytes are able to release antibodies which are Y shaped proteins that bind to infected microbes or cells of the body that have become infected.
What type of cell is a monocyte?
Monocytes can develop into two types of cell: Dendritic cells are antigen-presenting cells which are able to mark out cells that are antigens (foreign bodies) that need to be destroyed by lymphocytes. Macrophages are phagocyte cells which are larger and live longer than neutrophils.
Why are granulocytes called granulocytes?
Granulocytes are so called because these cells have granules of enzymes which help to digest the invading microbes. Granulocytes account for about 60% of our white blood cells.
What are the three types of granulocytes?
There are three different forms of granulocytes: Neutrophils. Eosinophils. Basophils. Granulocytes are phagocytes, that is they are able to ingest foreign cells such as bacteria, viruses and other parasites. Granulocytes are so called because these cells have granules of enzymes which help to digest the invading microbes.
Why are memory T cells important?
Memory T cells will be present after the body has fought off an infection and help the body to deal more easily with any future infection of the same type. Regulatory T cells (also known as suppressor T cells) help to regulate other T cells to prevent them targeting the body’s own cells.
