does memory b cells remember pathagens
Memory B and T cells are special because they are able to "remember" specific pathogens that the body has encountered before. This allows them to respond quickly and effectively to future infections, providing a faster and stronger immune response.
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.
Memory Cells
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.
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
Yes.First exposure: Sensitizing dose - elicits no symptomsMemory B cells are produced (now have the memory)Small amount of IgE antibodies are producedMast cells and basophils activatedSecond exposure: Allergens (those things that cause an allergy) bind to memory B cells.B cells produce large amounts of IgE antibodies (high titer)IgE bind to mast and basophil cellsRelease chemical mediators
this is called memory B cells
Mature B cells are responsible for producing antibodies, which are proteins that help the immune system recognize and fight off pathogens like bacteria and viruses. These cells can also develop into memory B cells, which provides long-lasting immunity against previously encountered pathogens.
Memory B and T cells are special because they are able to "remember" specific pathogens that the body has encountered before. This allows them to respond quickly and effectively to future infections, providing a faster and stronger immune response.
Memory B-cells
Yes, the immune system has memory cells called memory B cells and memory T cells. These cells are long-lived and can quickly recognize and respond to pathogens that the body has encountered before, leading to a faster and more robust immune response upon re-exposure.
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.

The type of white blood cells that can distinguish between different kinds of pathogens are called lymphocytes. They include T cells, which help coordinate the immune response, and B cells, which produce antibodies to neutralize specific pathogens. This ability to recognize and remember pathogens is essential for adaptive immunity.
T cells (Thymus cells) and B cells (bone cells).The function of T cells and B cells is to recognize specific "non-self" antigens, during a process known as antigen presentation. Once they have identified an invader, the cells generate specific responses that are tailored to maximally eliminate specific pathogens or pathogen infected cells. B cells respond to pathogens by producing large quantities of antibodies which then neutralize foreign objects like bacteria and viruses. In response to pathogens some T cells, called T helper cells, produce cytokines that direct the immune response while other T cells, called cytotoxic T cells, produce toxic granules that contain powerful enzymes which induce the death of pathogen infected cells.Following activation, B cells and T cells leave a lasting legacy of the antigens they have encountered, in the form of memory cells. Throughout the lifetime of an animal these memory cells will "remember" each specific pathogen encountered, and are able to mount a strong and rapid response if the pathogen is detected again.

When B cells are activated, some differentiate into plasma cells that produce antibodies to fight off pathogens in the body at that time. Others differentiate into memory B cells, which remain in the body to provide a faster and stronger immune response upon future encounters with the same pathogen.
