Which White blood cells that activate plasma cells?
Plasma Cells are, in fact White Blood Cells - they are a special group of Lymphocytes. Plasma Cells are also known as "Effector-B Cells" and are activated by the presence of antigens in the body
What the difference between a b cell and a b memory cell?
A plasma B cell is a B cell that has been activated to proliferate and produce antibodies against a specific antigen. A memory B cell is a B cell that lives a long time after an infection to provide long lasting immunity against that specific antigen. They both originate from the same B cell in your secondary lymph system. Once activated the specific B cell will proliferate into plasma B cells and memory B cells.
A lymphocyte that identifies pathogens and activate B cell?
nipples
Are Memory cells descendants of an activated B or T cell?
Yes
What binds with and releases chemicals that activate B cell and T cell and and macrophages?
Helper T cell
T cells and B cells activated only by what?
exposure to a specific antigen at a specific site in a plasma membrane.
What does a B-cell become when activated?
When B cells become activated they differentiate into two types of cells: plasma cells and memory cells. Plasma cells produce antibodies while memory cells linger in the system so if there is ever an invasion that the body has encountered before the body will know exactly how to destroy the pathogen.
What is bound to the surface of a B cell?
Antibodies. For an naive B cell it is generally IgM and IgD. An activated B cell will express IgA, IgE or IgG after it goes through isotype switching.
How can B cell mature into plasma cell?
The surface immunoglotulin that serves as the B-Cell antigen receptor (BCR) has two roles in B-cell activation. First, like the antigen receptor on T cells, it transmits signals directly to the cell's interior when it binds antigen. Second, the B-Cell antigen receptor delivers the antigen to intracellular sites where it is degraded and returned to the B-cell surface as peptides bound to MHC class II molecules.
What T-cell causes the B-cell lymphocyte to multiply in response to an infection?
Activated helper T cell will multiply and become either TH1 or TH2. TH2 is the one that activates the B cell population
Are B cells are activated with the help of TH2 cells?
Yes, Th2 cells activate B cells with mostly cytokines IL-4, IL-5, IL-10. Some B cells can activate without the help of Th2 cells, however, there are certain requirements for this such as repeated epitope.
What is the difference between a B cell and a memory B cell?
A plasma B cell is a B cell that has been activated to proliferate and produce antibodies against a specific antigen. A memory B cell is a B cell that lives a long time after an infection to provide long lasting immunity against that specific antigen. They both originate from the same B cell in your secondary lymph system. Once activated the specific B cell will proliferate into plasma B cells and memory B cells.
