Memory immune B cells are important in the secondary immune response - a process which has adapted to confer continued protection to the body from previously encountered pathogens or other invading substances. Memory B cells are the reason why we do not get the same infection twice. In a healthy individual, one infection is enough to stimulate the memory B cells to produce anitbodies to counteract the pathogen (or antigen). Upon concomitant infection, the body is already 'trained' to combat the infection. This is why memory B calls are so important to the proper functioning of the immune system.

What are long lived b cell clone members that do not become plasma cells but are capable of an immune response against the same antigen at a later time called?

Memory Cells


Memory B cells remember pathogens?

Yes, memory B cells are a type of immune cell that remembers past infections and can produce a quicker and stronger immune response upon reexposure to the same pathogen. This allows for faster clearance of the pathogen and provides long-lasting immunity.


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.


Anitgen-sensitized cells that remain in circulation for long periods of time?

Memory B cells and memory T cells are antigen-sensitized cells that can remain in circulation for long periods of time. These cells are part of the adaptive immune response and provide immunological memory, allowing for a faster and more effective response upon re-exposure to the same antigen.


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

If the same pathogen invades the body twice it will be recognized and destroyed more quickly the second time because of?

Memory B cells or Memory T cells


How b cell responds to the initial antigen challenge?

Upon initial antigen challenge, B cells with specific surface receptors that match the antigen become activated. These activated B cells differentiate into plasma cells that produce antibodies targeting the antigen. Additionally, some B cells can also become memory B cells to mount a faster and more robust immune response upon subsequent exposures.


Cells that remember how to make antibodies for a specific pathogen?

this is called memory B cells


Following a primary immune response the cells that give rise to memory cells are?

Following a primary immune response, memory cells are generated from activated B and T cells. These memory cells can recognize the same pathogen if encountered in the future, leading to a faster and stronger secondary immune response. Memory cells are vital for the immune system's ability to provide long-lasting protection against specific pathogens.

How do B cells respond to the initial antigen challenge?

B cells respond to the initial antigen challenge by producing progeny cells. The progeny cells include both memory cells and plasma cells.

Which cells make you immune to a disease that you were previously exposed to?

"Memory B cells" of the immune system stay in your body after an infection to enable quick immune responses to the disease-causing organism (antigen) if later exposed again. Antibodies are proteins made by the type of white blood cells called B-cells/"plasma cells" in response to the presence of antigens. The antibodies attach to the B-cells as "B-cell Receptors" to activate them, and can cause them to become either the memory B-cells or more plasma cells.


Are Memory cells descendants of an activated B or T cell?

Yes


What immunity results when millions of memory b cells remain in the body?

Memory b cells provide long term immunity for a specific disease or antigen. As an example a vaccination for hepatitis A provides memory b cells that will attack the disease when it is present and remove it.


Do memory cells aid the immune system?

YES! Memory cells, play a huge role in your immune system. While the primary response may not use memory cells, it does produce them, in the form of Memory B and Memory T cells.Memory B Cells have receptors for the antigen built into their membranes. When the antigen binds to these receptors, they activate the B cells. This causes the cell to undergo rapid divisions that produce more memory B cells and plasma cells (Effector B cells). The plasma cells go on to make antibodies to neutralize the pathogen, while the additional memory B cells can become activated and produce more plasma cells. This is called a humoral response.Memory T Cells work differently. These cells have a different type of receptor, that requires the antigen to be presented on an MHC (major histocompatibility complex) molecule on an infected host cell. If an antigen for that receptor is encountered these cells can in turn activate Cytotoxic (killer/effector) T cells to destroy the host cell. This is call a cell mediated response.In short, memory cells are a vital part of you immune system that allow for a faster response the second time you get infected. This is why you don't feel sick the second time you get a cold.
