What types of antigens are recognized by B cells?
Processed fragments of protein antigens displayed on surfaces of body cells.
What protects the body from free antigens?
The immune system protects the body from free antigens. It does so through the production of antibodies that recognize and neutralize antigens, as well as through the activation of immune cells, such as T cells and natural killer cells, that can directly destroy cells infected with antigens. Additionally, the immune system has memory cells that can recognize and respond more quickly if the same antigen is encountered again in the future.
What typoes of cells produce antigens?
All cells produce antigens, or cell surface markers. The only question is whether the antigens are self antigens which means they belong in the body or they're foreign antigens which means they are an invading bacteria or virus (or a cancerous cell).
Do antibodies attack extracellular or intracellular antigens?
Antibodies primarily target extracellular antigens, which are found outside of cells. These antigens can be on the surface of pathogens or released into the extracellular environment. Intracellular antigens, located inside cells, are primarily targeted by T cells of the immune system.
Do cancer cells have unique antigens?
They have not
Do T- Cells respond to antigens by becoming plasma cells?
No. B-Cells do.
What white blood cells are responsible for recognizing and destroying foreign antigens?
The white blood cells responsible for recognizing and destroying foreign antigens are called lymphocytes. There are two main types of lymphocytes: B cells, which produce antibodies to tag antigens for destruction, and T cells, which directly attack and destroy cells that are infected or presenting foreign antigens.
How does a B cell tell the difference between an invader cell and a body cell?
Antigens work as bar-codes to help the immune system differentiate between body cells and pathogens. Normally the body will not attack its own cells, but is programmed to attack those with foreign antigens.
What are antigens determining blood type carried on?
Antigens, by definition, cause the body to produce antibodies which act against them. You inherit certain antigens which are on your red blood cells. Sometimes these antigens are absent from your RBC. If you are type B, you have B antigens. Type A has A antigens, AB has AB antigens and type O has no antigens. If you are type AB, you can receive AB blood from some one else.
Does plasma cells eat invading antigens?
Yes. White blood cells eat the living and nonliving antigens that has entered in your body. They produce antibodies as a result.
How is it possible to determine blood types from other body cells such as cheek cells or skin cells?
Blood type is determined by the presence or absence of specific antigens on red blood cells. These antigens are not only present on red blood cells but also on other body cells, including cheek cells and skin cells. By analyzing the presence of these antigens on these cells, blood type can be determined.
What cells engulf antigens and present fragments of them on their own surfaces where they can be recognized by cells that will deal with them?
Antigen-presenting cells, such as dendritic cells, macrophages, and B cells, engulf antigens and present fragments of them on their cell surfaces. These antigens are then recognized by T cells, particularly CD4+ helper T cells or CD8+ cytotoxic T cells, which play a key role in initiating an immune response against the antigen.
