When an antigen stimulates b or t cells these b or t cells produce identical lymphocytes called what?
When an antigen stimulates B or T cells, these cells can produce identical lymphocytes through a process called clonal expansion. This results in a large population of identical cells that are all capable of recognizing and responding to the specific antigen that initiated the immune response.
Do plasma cells develop from t cells after exposure to an antigen?
No, plasma cells develop from B cells after exposure to an antigen. T cells play a role in activating B cells to differentiate into plasma cells and produce antibodies. Plasma cells are responsible for producing large amounts of antibodies specific to the antigen encountered.
What cell function indirectly to produce humoral immunity?
B cells are the primary cells involved in humoral immunity, and they indirectly produce this immunity through the secretion of antibodies. When B cells encounter an antigen, they can differentiate into plasma cells, which produce specific antibodies that bind to the antigen, neutralizing it or marking it for destruction. Additionally, helper T cells play a crucial role in activating B cells, enhancing their ability to produce antibodies and thus facilitating the humoral immune response.
When IL-2 is secreted by antigen-specific T cells activated due to presentation of antigen by APCs What happens to naive antigen-nonspecific T cells in the vicinity?
Naive antigen-nonspecific T cells do not become activated since they lack the T cell receptor specificity for the particular antigen being presented. They do not respond to IL-2 secreted by the activated antigen-specific T cells and remain in a resting state until they encounter an antigen to which they are specific.
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 an antigen stimulates b or t cells these b or t cells produce identical lymphocytes called what?
When an antigen stimulates B or T cells, these cells can produce identical lymphocytes through a process called clonal expansion. This results in a large population of identical cells that are all capable of recognizing and responding to the specific antigen that initiated the immune response.
What is the cell that produce antibodies to fight a specific antigen?
It is the B-cells.
Do plasma cells develop from t cells after exposure to an antigen?
No, plasma cells develop from B cells after exposure to an antigen. T cells play a role in activating B cells to differentiate into plasma cells and produce antibodies. Plasma cells are responsible for producing large amounts of antibodies specific to the antigen encountered.
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.
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.
What are B and T cells called that have not yet been exposed to an antigen?
B and T cells that have not yet been exposed to an antigen are referred to as "naive" cells. These cells are mature but have not yet encountered their specific antigen, which is necessary for their activation and differentiation into effector cells. Naive B cells can produce antibodies, while naive T cells can become cytotoxic T cells or helper T cells upon activation.
What are the 3 types of cells that helper t cells produce upon being alarmed of an antigen?
Helper T cells can produce three types of cells when alerted to an antigen: effector T cells, memory T cells, and regulatory T cells. Effector T cells help eliminate the antigen, memory T cells remember the antigen for future responses, and regulatory T cells help regulate the immune response to prevent excessive inflammation.
How do helper to cells and b cells work to eliminate antigens?
Helper T cells (CD4+ T cells) play a crucial role in the immune response by activating B cells and other immune cells. When they recognize an antigen presented by antigen-presenting cells, they release cytokines that stimulate B cells to proliferate and differentiate into plasma cells. These plasma cells then produce antibodies specific to the antigen, which neutralize or mark the pathogen for destruction. Together, helper T cells and B cells coordinate an effective immune response to eliminate the antigen from the body.
When IL-2 is secreted by antigen-specific T cells activated due to presentation of antigen by APCs What happens to naive antigen-nonspecific T cells in the vicinity?
Naive antigen-nonspecific T cells do not become activated since they lack the T cell receptor specificity for the particular antigen being presented. They do not respond to IL-2 secreted by the activated antigen-specific T cells and remain in a resting state until they encounter an antigen to which they are specific.
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.
Which of the following initiates an attack against a specific antigen or pathogen?
Plasma Cell initiate attacks against specific antigens. Plasma cells are B cells bearing specific antibodies for binding to a specific antigen.
Remain in reserve then turn into plasma cells when needed?
B cells can remain in reserve as memory cells until they encounter the specific antigen they were created to target. Once activated by this antigen, they can differentiate into plasma cells, which produce large amounts of antibodies to combat the infection. This process allows for a rapid and specific immune response upon re-exposure to the pathogen.
