What are long lived b cell clone members that do not become plasma cells but are capable of an immune response against the same antigen at a later time called?
Memory Cells
What gives a rise to plasma cells during primary immune response?
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.
How do memory cells differ from effector cells?
Memory cells live longer than effector cells and are responsible for the secondary immune response
Following a primary immune response the cells that give rise to memory cells are?
Both B cells and T cells
Which cell types initiate a secondary immune response?
Memory cells
Development of a secondary immune response is based on populations of?
memory cells
Why is it adaptive for memory cells to remain in the immune system after an invasion by pathogens?
As a result of memory cells, on exposure to a second infection by the pathogen the response will be quicker and stronger.
Would lack of memory B cells for a particular antigen impact the primary or secondary humoral response?
secondary humoral response.
Do memory cells aid the immune system?
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 (Effector B cells). The plasma cells go on to make antibodies to neutralize the pathogen, while the additional memory B cells can become activated and produce more plasma cells. This is called a humoral response.Memory T Cells work differently. These cells have a different type of receptor, that requires the antigen to be presented on an MHC (major histocompatibility complex) molecule on an infected host cell. If an antigen for that receptor is encountered these cells can in turn activate Cytotoxic (killer/effector) T cells to destroy the host cell. This is call a cell mediated response.In short, memory cells are a vital part of you immune system that allow for a faster response the second time you get infected. This is why you don't feel sick the second time you get a cold.
After the first exposure to an antigen what carries the record of the exposure in the body?
Memory B cells and memory T cells carry the record of the first exposure to an antigen in the body. These cells are generated during the initial immune response and remain in the body to provide a faster and stronger immune response upon re-exposure to the same antigen.
Which cells make you immune to a disease that you were previously exposed to?
"Memory B cells" of the immune system stay in your body after an infection to enable quick immune responses to the disease-causing organism (antigen) if later exposed again. Antibodies are proteins made by the type of white blood cells called B-cells/"plasma cells" in response to the presence of antigens. The antibodies attach to the B-cells as "B-cell Receptors" to activate them, and can cause them to become either the memory B-cells or more plasma cells.
What are the immune cells that produce free antibodies?
B lymphocytes that will divide to form 1.plasma cells which produce specific antibodies and 2.memory cells which is the basis of immunological response.
