Where does plasma cells develope from?
Plasma cells develop from B lymphocytes (B cells) after they encounter an antigen and receive appropriate signals, typically from helper T cells. Upon activation, B cells undergo a process called clonal expansion, differentiating into plasma cells, which are responsible for producing and secreting antibodies. This transformation occurs primarily in the bone marrow and lymphoid tissues.
What does not serve as an antigen-presenting cell?
Red blood cells do not serve as antigen-presenting cells. Antigen-presenting cells include dendritic cells, macrophages, and B cells, which play a crucial role in initiating immune responses by presenting antigens to T 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.
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.
Cell mediated immunity anatomy definition?
Immunity independent of antibody but dependent on the recognition of antigen by T cells and their subsequent destruction of cells bearing the antigen or on the secretion by T cells of lymphokines that enhance the ability of phagocytes to eliminate the antigen.

What type of cells makes blood cells?
antigen
How do B cells respond to the initial antigen challenge?
B cells respond to the initial antigen challenge by producing progeny cells. The progeny cells include both memory cells and plasma 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.
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.
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.

What is the function of an antigen in an antigen-antibody response?
To help immune cells identify and destroy a pathogen
What are the cells that stay young not elongating not differentiating?
Stem cells are the cells that stay young by not elongating or differentiating. These cells have the ability to self-renew and differentiate into various cell types, allowing for tissue regeneration and repair throughout an organism's lifespan.
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.
Antigens cause immature B cells to?
When a B cell detects an antigen, it will engulf it and then display it on its cell surface with an MHC molcule. This antigen/MHC combination is then detected by a T cell - which will send signalling molcules to B cells to multiply and mature into plasma cells (which create antibodies against the antigen) and memory B cells (which 'remember' the antigen for next time).They become plasma cells
