What else can I help you with?
Blocking the antigen receptors on the surface of the lyphovytes would interfere with what?
destroying the antigen
What Organelles do Lymphocytes have?
A lymphocyte is a type of white blood cell. The major organelles that are present in lymphocytes include ribosomes, lysosomes, mitochondria, nucleus and Golgi apparatus.
Any molecule that triggers the formation of lymphocytes and is their target is?
antigen
What is involved in clonal expansion?
B-lymphocytes, T4-helper lymphocytes, cytokines, and most importantly pathogens (they're what triggers it in the first place).As B-lymphocytes are maturing and differentiating, each creates a specific antigen-binding site that's fairly unique. When antigens bind to the appropriate B-lymphocytes and activate them, active T4-helper lymphocytes sensitive to the same antigen (effector T4-helper lymphocytes) produce proteins called cytokines to switch on the activated B-lymphocytes' ability to rapidly divide. The process of clonal expansion itself is just the B-lymphocytes and T4-helper lymphocytes suited to the particular antigen rapidly increasing in number and mutating as they do so to better adapt to the antigen; the T4-helper lymphocytes also experience a similar clonal expansion.
What is the structure of T lymphocytes?
T lymphocytes are characterized by a round or oval nucleus with a small amount of cytoplasm. They have cell surface receptors that can recognize specific antigens presented by antigen-presenting cells. T lymphocytes differentiate into various subsets such as helper T cells, cytotoxic T cells, regulatory T cells, and memory T cells.
Type blood has B antibodies?
Has no antigen in many textbooks it will state "no A-antigen and no B-antigen"(which imply the possibility of some other antigen) and some will even say, "no antigen" (which is true; antigens are things that attach to antigen binding sites, thus, if it does not fit any antigen binding sites, it is technically not a antigen but merely a "enzyme/protein") but this is just to reduce unnecessary and irrelevant information; they are only concerned about A-antibody, B-antibody, A-antigen, and B-antigen. Nonetheless, know that there are in fact antigens on o blood cells, they are just inactive. My guess is, N acetyl glactosamine on A antigen and Galactose on B antigens are Epitopes (: a small specific regions on antigens that are bound by the antigen receptors on lymphocytes and by secreted antibodies.) Antigens without epitopes will not be detected by antigen binding sites.
What is hepatitis virus tests?
These tests are based primarily on antigen-antibody reactions--an antigen being a protein foreign to the body, and an antibody another type of protein manufactured by lymphocytes (a type of white blood cell) to neutralize the antigen.
Where do undifferentiated lymphocytes migrate to?
B lymphocytes develop in the bone marrow. They then chill out in the blood until they meet an antigen that they are encoded and they become activated. However they need to be checked by another immune cell before to present auto-antigen. Once activated they then go to the spleen.
When an antigen stimulates b or t cells these b or t cells produce identical lymphocytes called what?
When an antigen stimulates B or T cells, these cells can produce identical lymphocytes through a process called clonal expansion. This results in a large population of identical cells that are all capable of recognizing and responding to the specific antigen that initiated the immune response.
What is a disease- fighting protein created by the immune system in response to the presence of specific antigen?
Antibody - produced by B lymphocytes.
When do lymphocytes become immunocompetent?
each lymphocyte must become able (competent) to recognize its one specific antigen bye binding to it. this ability is called immunocompetence.
How are the roles of b and t cells different how are their roles similar?
Both are T and B lymphocytes are produced in bone marrow, but B lymphocytes mature in bone marrow and are part of the humoral response, while T lymphocytes mature in the thymus gland and are part of the cell mediated response.
