Yes.
First exposure: Sensitizing dose - elicits no symptoms
Second exposure: Allergens (those things that cause an allergy) bind to memory B cells.
does memory b cells remember pathagens
this is called memory B cells
Memory B-cells
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.
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.
exogenous pathogens.
They transform themselves to lots of plasma cells, which create antibodies to fight against the pathogens.

B-cells produces antibodies that target specific pathogens so t-cells can then recognize it and consume it.
the body's second line of defense against pathogens is the B cells.
