Memory cell may refer to:
Memory B cell, a type of biological cell
In computer science, a memory cell is a building block of computer memory
[MemoryCell] is an application for the Macintosh computer.
memory cell
A clone of long-lived lymphocytes, formed during the primary immune response, that remains in a lymph node until activated by exposure to the same antigen that triggered its formation.
memory cells.
Experienced T (or B) cells that have returned to — or remained in — a quiescent state.
B memory cells Long-lived B cells that are produced after an initial exposure to an antigen and play an important role in secondary immunity. They remain in the body and facilitate a more rapid responce if the antigen is encountered again.
memory cell A lymphocyte capable of initiating the antibody- mediated immune response on detection of a specific antigen molecule for which it is genetically programmed. It circulates freely in the blood and lymph, and may live for years.
After exposure to an allergen, some people make IgE antibodies as well as B and T memory cells. Subsequent exposure to the same allergen causes a massive secondary immune response that releases plenty of IgE antibodies.
Thus, our memory cells are rapidly infected and destroyed in the mucus membranes of our tissues.
Primary response produces memory cells which remain in the circulation
Secondary response new invasion by same antigen at a lower state. Immediate recognition and distraction by memory cells -faster and larger response usually prevents harm ...
Their antigen receptors are surface immunoglobulins (antibodies). They recognize peptides directly and secrete antibodies by differentiating into plasma cells. They also exist as long-lived memory cells.
If a pathogen the body has already encountered invades, memory B cells can recognize the pathogen and start to divide. Quickly, they form a new generation of cells, and memory cells.
They go through what we were talking about earlier: program cell death or apoptosis. So you lose them. You'll save a few of them-they're memory cells-so if that organism comes in again, they can react very quickly.
