Activated B cells are immune cells that have undergone a process of activation in response to an antigen, typically following interaction with helper T cells. Upon activation, these B cells proliferate and differentiate into plasma cells, which produce antibodies specific to the encountered antigen. They also form memory B cells that provide long-lasting immunity by remaining in the body to respond more rapidly upon future encounters with the same antigen. This process is essential for the adaptive immune response and the development of immunological memory.
What else can I help you with?
T cells and B cells activated only by what?
T cells are activated by antigens presented on the surface of antigen-presenting cells, such as dendritic cells. B cells are activated primarily by recognizing antigens with their B cell receptor, although they may also require T cell help for full activation.
When B-cells are activated they divide to form antibody-producing cells called?
Plasma cells.
Antibodies are produced by?
Activated B cells, called plasma cells, are responsible for producing antibodies
What does a B-cell become when activated?
When activated, a B-cell can differentiate into plasma cells that produce antibodies to fight off pathogens. Additionally, B-cells can also become memory B-cells that can quickly respond to future infections by the same pathogen.
How do B cells get activated in the immune response process?
B cells get activated in the immune response process when they encounter a specific antigen that matches their receptors. This triggers the B cell to divide and differentiate into plasma cells, which produce antibodies to target and neutralize the antigen.
Are Memory cells descendants of an activated B or T cell?
Yes
Which type of immune cells do most activated B-lymphocytes differentiate into?
Most activated B-lymphocytes differentiate into plasma cells, which are a type of immune cell that produces antibodies to help fight off infections.
Plasma cells develop from transformed b cells or t cells?
ativated B cells forms effector cells which are called plasma cells
What process provides many b cells and t cells that are activated against specific antigens?
The process of clonal selection in the immune system produces numerous B cells and T cells that are activated in response to specific antigens. This involves the proliferation of cells that have receptors capable of binding to a particular antigen, resulting in an amplified response to combat the invading pathogen.
How b cell responds to the initial antigen challenge?
Upon initial antigen challenge, B cells with specific surface receptors that match the antigen become activated. These activated B cells differentiate into plasma cells that produce antibodies targeting the antigen. Additionally, some B cells can also become memory B cells to mount a faster and more robust immune response upon subsequent exposures.
When b cells are activated some mass produce antibodies while other become - to protect the body of a later date?
When B cells are activated, some differentiate into plasma cells that produce antibodies to fight off pathogens in the body at that time. Others differentiate into memory B cells, which remain in the body to provide a faster and stronger immune response upon future encounters with the same pathogen.
How does the activation of B cells occur in the immune response?
B cells are activated in the immune response when they encounter a specific antigen that matches their receptors. This triggers the B cells to multiply and differentiate into plasma cells, which produce antibodies to target and neutralize the antigen.
