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.

Antigens cause immature B cells to?
When a B cell detects an antigen, it will engulf it and then display it on its cell surface with an MHC molcule. This antigen/MHC combination is then detected by a T cell - which will send signalling molcules to B cells to multiply and mature into plasma cells (which create antibodies against the antigen) and memory B cells (which 'remember' the antigen for next time).They become plasma cells
The cytoplasmic structure in a bacterial cell is the a. cell wall b. nucleoid c. plasma membrane d. ribosomes?
b-nucleoid
Which two mature blood cell types descend from myeloblasts?
Neutrophils and eosinophils descend from myeloblasts, which are a type of precursor cell for granulocytes in the bone marrow. These mature blood cells are part of the innate immune system and play key roles in fighting infections and regulating inflammation.
Another name for plasma membrane?
A cell membrane is also known as a plasma membrane or cytoplasmic membrane. The cell membrane separates the interior of a cell from its outside environment. The main function of a cell membrane is to protect the cell from its surroundings.
B cell maturation?
B cell maturation occurs in the bone marrow where progenitor B cells undergo a series of developmental stages, including rearrangement of immunoglobulin genes to generate a diverse B cell receptor repertoire. This process involves negative and positive selection to ensure self-tolerance and functional B cell development. Mature B cells then migrate to secondary lymphoid tissues where they can be activated by antigens.
A mature B cell that mass produces antibodies is called a?
A mature B cell that mass produces antibodies is called a plasma cell. Plasma cells are differentiated B cells that are specialized for producing large quantities of antibodies to help fight infections.
How is immunoglobulin made?
Immunoglobulins, more commonly referred to as antibodies.- Immunoglobulins/antibodies are synthesized by plasma cells which is a specialized type of B-cell. Immature B-cells are produced in red bone marrow and then migrating to the spleen where some of them mature to a mature B-cell. A mature B-cell can differentiate into either a memory B-cell or a plasma cell."- In human adults, Immunoglobulins are synthesized by plasma cells (specialized type of B-cell) which in turn originates from red bone marrow in large bones (eg. femur).
Antigens cause immature B cells to?
When a B cell detects an antigen, it will engulf it and then display it on its cell surface with an MHC molcule. This antigen/MHC combination is then detected by a T cell - which will send signalling molcules to B cells to multiply and mature into plasma cells (which create antibodies against the antigen) and memory B cells (which 'remember' the antigen for next time).They become plasma cells
What are B cells plasma cells and antibodies a part of?
B cells, plasma cells, and antibodies are all part of the immune system. B cells are a type of white blood cell that produce antibodies when activated by antigens. Plasma cells are a mature form of B cells that secrete large amounts of antibodies. Antibodies are proteins produced by B cells that help to neutralize pathogens and foreign substances in the body.
What blood cell can become an antibody-secreting cell is?
The cell which can secret antibody are called B-Lymphocytes. Those cells are generally called as B-Cells.
Which cell develops into a plasma cell?
Stem cells develop into plasma cells and B cells also turn into plasma cells. Plasma cells have been exposed to an antigen and then produces and secretes antibodies.
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.
Are plasma cells specialized B cells?
Yes, plasma cells are specialized B cells. They are derived from B cells and are responsible for producing and secreting antibodies or immunoglobulins in response to an antigen. Plasma cells are a critical component of the immune system's humoral response.
Who is responsible for antibody production?
Naiive B cells are lymphocytes that have not yet been exposed to antigen. Once it can identify a particular antigen, it will undergo production of antibodies and become a mature B cell. Mature B cells are split into two categories: plasma B cells and memory B cells. Plasma B cells will continue to produce large amounts of antibodies. Memory B cells are stored so that the next time you encounter the same antigen, it can start producing antibodies much quicker because it remembered from the previous encounter.
What are the progeny cells of a B-cell clone called?
The progeny cells of a B-cell clone are called plasma cells. Plasma cells are responsible for secreting large quantities of antibodies specific to a particular antigen.
What subgroup of the b cell clone that secretes antibodies?
plasma cells
What cell is an antibody factory?
Plasma cells, which are derived from B cells.
