What is an adpitive cell?

An adaptive cell, often referred to in the context of the immune system, is a type of lymphocyte that can recognize and respond to specific pathogens. These cells, primarily T cells and B cells, have the ability to adapt and form memory after an initial exposure to an antigen, allowing for a more rapid and effective response upon subsequent encounters with the same pathogen. This adaptability is crucial for the development of long-lasting immunity and is the basis for how vaccines work.
