What are memory T cells?
A memory T cell is an "experienced" T cell. While normal infection/cancer fighting T cells will mount a defense within the body by replicating themselves to fight off the infection. A memory T cell is able to mount a defense and replicate itself faster because it has encountered a particular type of invader before.
T cells gain memory by fighting off infections or by encountering injected vaccinations in the blood stream. (vaccinations contain dead infections which cannot infect the body, but the T cells still latch onto them and remove them and thus learn how to fight off that infection if it were alive). Memory T cells can also be developed in young children during breast feeding as they will learn from the strains passed over from the mother which have already been killed off by her immune system.
T cells are why we are able to get sick and recover within a few days. Memory T cells are why we are able to either avoid the same strain of infection or at least reduce its recovery time if we encounter it again.
Do activated Tc cells only turn in to cytotoxic T-lymphocytes or do Tc differentiate into memory cells as well?
Activated Tc cells can proliferate into cytotoxic t-lymphocytes and Memory cytotoxic t cells as well. Read More
Memory cells, or T cells, are part of the immune system and carried in the blood stream. Due to the fact that they are carried in blood, the heart does help pump them, but it does not "have" memory cells of its own. Read More

There are 3 main types. NK (natural killer) cells, T-cells and B cells. T cells have sub categories mainly helper T (CD4+) and Killer T (CD8+), and to a lesser learned extent, suppressor T (memory T also). B cells (mature) consist of memory B and Plasma cells. Read More
Both B cells and T cells Read More
Memory B cells send out T cells to do the fighting - these cells are called antibodies. Read More
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 Read More
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… Read More

No. There are many types of T-cells, including Helper T cells and Regulatory T cells (formerly known as suppressor cells). B cells are responsible for the creation of antibodies (and memory B cells). Read More
a vaccination is a dead or deactivated virus. the body treats the vaccine as a threat to the body, so it fights the disease. it leaves you with memory T (killer cells) and B (cells that create antibodies). when the actual disease comes, the memory B cells make antibodies that stick to the disease cells antigens, and the memory T cells kill the disease, to end the disease before it can start.

The parts of the immune system are: macrophages, histamines, helper t cells, interleukins, b cells, antibodies, cytoxic t cells, and memory b cells. Read More
There are 4 t cells. Memory t cells which remember the codes of the pathogen. Killer t -kills bacteria, helper t- helps it, suppressor t-stops them from fighting bacteria. Read More
b lymphocyes - plasma and memory and t lymphcytes - cytotoxic, helper, memory and supresser Read More
These are the main cells of the Immune system. B cells create antibodies, which attach themselves to the pathogen and disable it. Killer T Cells do exactly what their name describes: they kill cells that have become infected by viruses. Read More
If im correct, helper t-cells activate: b-cells that mark viruses and make them stick together, killer t-cells --which attack macrophages and infected cells, and memory b-cells, which remember how to stop viruses, this i believe is called active immunity Read More
Memory cells live longer than effector cells and are responsible for the secondary immune response Read More
Memory cells divide into plasma cells that produce the right antibody. Read More
Yes immune system have memory cells. they flow around the blood. Read More
There are two major cell populations that are responsible for "memory" in the immune system T and B cells. B cells produce antibodies that neutralize antigens, blockade the pathogens receptors, or otherwise mess with the ability of these pathogens to function. T cells can develop into central memory or effector memory cells, each type is defined by how long they hand around in the body and how easy it is for them to respond to… Read More
Antibodies are produced by: Cytotoxic T cells. Helper T cells. Suppressor T cells. Plasma cells. B memory cells. IgE antibodies are made by dander cells Read More
Memory cells have a long lifespan. They could live for years..... This is in contrast with effector cells which lifespan is days or with Naive cells which lifespan is weeks or months. Read More
The vaccination is basically a deactivated virus or something that simulate the virus, so it tricks your body into thinking that you have the virus. Your body then produces antibodies through cells called b cells and attacks the virus with cells called t cells. On your first encounter with the virus, it may take a while to find these cells in your body, because you only have one of each, bu once they are found… Read More
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… Read More
How do cells involved in the humoral response respond to antigen presentation on the surface of a B cell?
Helper T cells recognize the receptor-antigen complex and cause plasma and memory cells to be produced to then produce antibodies. Read More
The acquired immune response is also known as the specific immune response. This involves the presentation of micro organisms antigens by macrophages to T and B lymphocytes (T and B cells). T cells and B cells specific to these antigens will then go through clonal expansion (mass production) to help carry out a specific response that has been 'acquired' as a direct result or particular microorganisms antigens. T cells are divided into T helper and… Read More
There are different types of B cell and T cell. both are lymphocytes, a subclass of white blood cell. the T cells are mainly used in identifying antigens and releasing chemicals which attact macrophages (big immune cells which 'eat' antigens), to destroy the antigen. B cells are used in the production of antibodies. when they encounter a new antigen, plasma cells and memory cells are formed from the devision of a B cell. the memory… Read More
Helper T cells help to activate T-cytotoxic cells and B-cells. For instance, if you become infected with a pathogen, a macrophage can consume that pathogen and then present parts of it on its own MHC (Major Histocompatability Complex) receptors. T helper cells then detect this and if this is a pathogen previously encountered, it can stimulate T-cytotoxic cells to begin attacking infected cells, and stimulate B-memory cells to begin rapidly dividing into B-plasma cells to… Read More

Once the body activated, killer T cells it recognize pathogen and destroy them. In response that will create memory B cells and T cells specific to a certain pathogen, so if it ever came back it will be killed immediately. Read More
B-cells differentiate into plasma cells and memory cells in the primary immune response. The memory cells then produce antibodies. In the secondary, memory cells created in the primary differentiate into plasma cells and secrete antibodies immediately. This is a much faster response, explaining why the secondary response causes a person to suffer less or unnoticeably. Read More
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. Read More
T-suppressor cells: T cells that express the CD8 transmembrane glycoprotein (CD8+ T cells). They close down the immune response after invading organisms are destroyed. Suppressor T cells are sensitive to high concentrations of circulating lymphokine hormones, and release their own lymphokines after an immune response has achieved its goal. This signals all other immune-system participants to cease their attack. Some memory B-cells remain after this signal to ward off a repeat attack by the invading… Read More

it is the center of immune response it activate the B-lymphocyte to divide and form plasma cell and then formation of memory cells and antibody . (Egyptian). Read More
The three major types of lymphocytes are the T-cells, B-cells, and NK cells. NK cells, natural killer cells, are cells that detect other cells with tumors or otherwise altered cells and are naturally in the blood stream. B-cells secrete antibodies, which mark a pathogen for destruction and "chain" it down. T-cells come in multiple types, mainly helpers, which help other cells of the immune system develop, cytotoxic T-cells, which attempt to destroy infected cells/pathogens, and… Read More
As a result of memory cells, on exposure to a second infection by the pathogen the response will be quicker and stronger. Read More
because it kills brain cells and some brain cells have memory and if your memory is killed you will not know what that brain cell had stored Read More
The idea of immunisation is that you expose the immune system to the pathogen, ennabling it to recognise the pathogen and produce mature memory Helper T cells. This means that upon its second exposure the immune system is activated faster and more efficiently, allowing the immune system to kill off the pathogen quicker. In some cases antibodies are produced that can neutralise toxins, preventing their damaging effects. If memory T cells were not produced then… Read More
depends which brain cells die but any one of them dieing is bad. if memory cells die then u lose memory and cant learn or something like that Read More
