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.
According to the clonal selection theory foreign antigens select and interact with surface receptors only on the membranes of those specific lymphocytes that are genetically capable of making antibod?
False
The cell types that are most responsible for presenting foreign antigens together with surface antigens to specific receptors on the membrane of T lymphocytes are the macrophages and?
dendritic cells. These cells play a crucial role in activating T lymphocytes and initiating an immune response against foreign antigens by presenting antigens to the T cell receptors (TCR) on the surface of T lymphocytes. This interaction leads to the activation and proliferation of specific T cell populations to combat the invading pathogen.
What defense target specific pathogens?
Lymphocytes
Specialized cells that attack foreign substances upon recognizing the foreign surface antigens are called?
These specialized cells are called immune cells, particularly T cells and B cells. They play a crucial role in the body's immune response by identifying and responding to foreign antigens to eliminate them and protect the body from infections.
What are lymphocytes formed in thymus gland that act on antigens?
t cells
Lymphocytes that act directly on antigens to destroy them or produce chemicals that are toxic to them called?
Lymphocytes that act directly on antigens to destroy them or produce chemicals that are toxic to them are called T4 cells. They are also known as T helper cells.
What type of white blood cell releases antibodies?
The answer is Lymphocytes. However, they do not RELEASE antibodies. When there is an increase in lymphocytes this indicates a viral infection. Internally, this viral infection is represented as a foreign antigen that could potentially weaken the immune system. Once these foreign antigens are detected this triggers antibodies to form to eliminate the same antigens that created them (the viral infection). These antibodies are what work to fight away the viral infection to return the body to its original state.
What are specialized white blood cells that produce antibodies coded to destroy specific antigens?
the B-cells.
What forms in the blood to help fight invading antigens?
White blood cells, specifically lymphocytes, are responsible for helping to fight invading antigens in the blood. These cells produce antibodies that target and neutralize foreign substances, such as bacteria or viruses. Additionally, white blood cells can mount an immune response to destroy these antigens and prevent infection.
What is also known as B lymphocytes?
Lymphocytes play a role in body's natural defense. They are comprised of B cells and T cells. T cells are cellular mediators of immunity whereas B cells differentite into immunoglobulin-synthesizing plasma cells. If T cells are fighters, B cells like to 'prepare' by synthesizing antibodies to the invading antigens.
What is agglutination in biology?
agglutination is when B-lymphocytes, more specifically plasma B-cells, link antigens together using the binding sites on the antigens. This prepares the antigens for phagocytosis or perforation from a killer T-cell
