B cells are primarily activated by the activities of A antigens B macrophages C helper T cells D antibodies E plasma cells?
Antibodies are produced by B lymphocytes. An antibody is a class of proteins produced by B lymphocytes, sometimes known as B cells. To neutralize diseases or foreign substances like poisons, these antibodies bind to them. For instance, an antibody can attach to a virus, preventing it from infecting a healthy cell and spreading. B cells can enlist the aid of other cells in the fight against an infected cell. Central BioHub offers thousands of B cells collected from patients and healthy donors for research.

Which vesicular transport process occurs primarily in some white blood cell and macrophages?
Endocytosis
What are Antibodies are composed primarily of amino acids what class would antibodies belong?
Antibodies are proteins, which are macromolecules composed primarily of amino acids. They belong to the class of biomolecules known as globular proteins, characterized by their complex three-dimensional structures that enable specific binding to antigens. Antibodies play a crucial role in the immune system by identifying and neutralizing pathogens.
The widely distributed phagocytic cellls that remain in fixed position constitute what tissue?
These are called macrophages and are part of the reticuloendothelial system, primarily found in tissues such as the liver, spleen, and lymph nodes.
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.
Where does the primary humoral response occur?
The primary humoral response primarily occurs in the lymphoid organs, such as the spleen and lymph nodes. When B cells encounter their specific antigen, they become activated and differentiate into plasma cells, which produce antibodies. This process also involves the activation of helper T cells, which provide necessary signals for B cell proliferation and differentiation. Ultimately, the antibodies secreted into the bloodstream help to neutralize the pathogen.
Antibodies found in blood type A positive?
Individuals with blood type A positive have antibodies against blood type B antigens. This means their immune system reacts against blood from individuals with blood type B if they were to receive a transfusion containing type B blood.
Is phagocytic a characteristic of all leukocytes?
No per Marieb. Basophils just release histamine and mediators of inflammation and they also contain helarin. Lymphocytes mount immune response by cell attack or via antibodies. The rest do phagoctytize.
What is ox-42?
Ox-42 is a monoclonal antibody that specifically binds to the CD11b component of the integrin complex, which is primarily expressed on myeloid cells, including microglia and macrophages. It is often used in neuroscience research to label and study activated microglia in various models of neuroinflammation and neurodegenerative diseases. By binding to these cells, researchers can visualize and analyze their activation states and roles in health and disease.
Antibodies are primarily effective against rather than?
effective against soluble antigens than the insoluble antigen
How do protein A and protein G differ in their ability to bind to specific antibodies?
Protein A and protein G differ in their ability to bind to specific antibodies based on their binding preferences. Protein A primarily binds to antibodies from the IgG class, while protein G has a broader binding range and can bind to antibodies from multiple classes, including IgG, IgM, and IgA.
How do macrophages travel throughout the body?
Macrophages primarily travel throughout the body through the bloodstream and lymphatic system. They can move to areas of infection or inflammation in response to chemical signals released by damaged tissues or invading pathogens. Once they reach their target destination, macrophages can squeeze through blood vessel walls to enter the surrounding tissues and carry out their immune functions.
Where do macrophages destroy old red blood cells?
Macrophages primarily destroy old red blood cells in the spleen, although this process can also occur in the liver and bone marrow. The spleen serves as a key organ for filtering the blood and removing aged or damaged erythrocytes. Once engulfed, macrophages break down the hemoglobin within red blood cells, recycling iron and other components for future use.
