What does a B-cell become when activated?
When B cells become activated they differentiate into two types of cells: plasma cells and memory cells. Plasma cells produce antibodies while memory cells linger in the system so if there is ever an invasion that the body has encountered before the body will know exactly how to destroy the pathogen.
Which White blood cells that activate plasma cells?
Plasma Cells are, in fact White Blood Cells - they are a special group of Lymphocytes. Plasma Cells are also known as "Effector-B Cells" and are activated by the presence of antigens in the body
How b cell responds to the initial antigen challenge?
producing progeny cells that include plasma cells and memory cells
Are plasma cells specialized B cells?
yes . the memory b cell divide rapidly forming new plasma cell
What are the names of all the cells in your body?
There are a lot of cells in the body but, i can only name a few (if it helps): red blood cells white blood cells, T-cell cheek cell, Hair cell eye cells Stem cell nerve cells Heart cell skin cell liver cell sperm cell muscles cell egg cell connective cell fat cell pancreatic cell memory cell goblet cell brain cell bone cell Hope that helped :D

What the difference between a b cell and a b memory cell?
A plasma B cell is a B cell that has been activated to proliferate and produce antibodies against a specific antigen. A memory B cell is a B cell that lives a long time after an infection to provide long lasting immunity against that specific antigen. They both originate from the same B cell in your secondary lymph system. Once activated the specific B cell will proliferate into plasma B cells and memory B cells.

What is the clonal selection theory as it applies to B cells?
1. An antigen presenting cell presents antigen on Class II MHC to a Helper T cell activating it 2. At the same time a B cell that has taken up and degraded the same pathogen displays antigen on its class II 3. The activated helper T cell binds to the B cell releasing cytokines and activating it 4. The activated B cell proliferates and differentiates into: 1) memory B cells 2) antibody-secreting plasma cells that produce antibodies specific for the pathogen
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.
What is a memory cell made of?
white blood cells
How b cell responds to the initial antigen challenge?
producing progeny cells that include plasma cells and memory cells
Are plasma cells specialized B cells?
yes . the memory b cell divide rapidly forming new plasma cell
How does a liver cell differ from a heart cell?
brain cells are activated by brain genes and heart cells are activated by heart genes. that's how they function, by their genes
How are helper t cells activated?
It is a type of leukocyte, or white blood cell, but it has no ability to ingest or destroy invading bacteria. It activates other white blood cells or antibodies to react with the invading organism.
Which cell types initiate a secondary immune response?
Memory cells
