Cells that remember how to make antibodies for a specific pathogen?
this is called memory B cells
What is clonal selection responsible for?
Clonal selection is responsible for the proliferation of clones of effector and memory cells specific for an encountered antigen
What is major difference between specfic and non specfic immunity?
Specific immunity follows a non-specific response. The major difference between specific and non-specific is the ability to remember pathogenic antigens. Specific immunity results in the production of memory cells which upon reinfection are used to effectivly remove the pathogen Non-specific cannot do this
Memory B cells remember pathogens?
does memory b cells remember pathagens
What is acquired Immune Response?
The acquired immune response is also known as the specific immune response. This involves the presentation of micro organisms antigens by macrophages to T and B lymphocytes (T and B cells). T cells and B cells specific to these antigens will then go through clonal expansion (mass production) to help carry out a specific response that has been 'acquired' as a direct result or particular microorganisms antigens. T cells are divided into T helper and T killer, and B cells into memory cells and plasma cells. T helper cells aid B cells in their production and carrying out their functions. T killer cells kill infected cells (those containing viruses or bacteria, as detected by their presentation of antigen on MHC Class 1 receptor molecules on their surface). B cells differentiate into plasma cells and memory cells, plasma cells produce antibodies specific to the type or types of antigens detected. Memory cells have the ability to live for long amounts of time and quickly differentiate into plasma cells should the same antigens present at a later date, allowing a faster and more efficient immune response if infected again with the same microorganism. The acquired immune response usually takes 7-10 days after initial presentation of the antigens by macrophages - unless this is a secondary response, in which case the person should have already produced memory cells so can deal with the invading microorganisms faster and more efficiently. The innate (passive) immune system is responsible for initial responses, this is non specific and involves neutrophils largely.
What protects the body from free antigens?
The immune system protects the body from free antigens. It does so through the production of antibodies that recognize and neutralize antigens, as well as through the activation of immune cells, such as T cells and natural killer cells, that can directly destroy cells infected with antigens. Additionally, the immune system has memory cells that can recognize and respond more quickly if the same antigen is encountered again in the future.
What do t cells do?
(t-cells) are involved in cell mediated immunity that can have memory of previous antigens(non self) that have invaded our body. cytotoxic tcells release preforin that destroy tumor cells or antigens helper tcells release cytokines/interlukins that help in more tcell differentiation
What process provides many b cells and t cells that are activated against specific antigens?
Clonal expansion is the process that provides many B cells and T cells that are activated against specific antigens. Clonal expansion is what provides the immune system its strength.
What are specialized white blood cells that produce antibodies coded to destory specific antigens?
plasma cells
Are specialized white blood cells that produce antibodies coded to destroy specific antigens?
plasma cells
What medical term specialized white blood cells that produce antibodies coded to specific antigens?
all wbc produce antibodies to attach the the pathogens antigens.
What do B and T lymphocytes do?
T cells (Thymus cells) and B cells (bone cells).The function of T cells and B cells is to recognize specific "non-self" antigens, during a process known as antigen presentation. Once they have identified an invader, the cells generate specific responses that are tailored to maximally eliminate specific pathogens or pathogen infected cells. B cells respond to pathogens by producing large quantities of antibodies which then neutralize foreign objects like bacteria and viruses. In response to pathogens some T cells, called T helper cells, produce cytokines that direct the immune response while other T cells, called cytotoxic T cells, produce toxic granules that contain powerful enzymes which induce the death of pathogen infected cells.Following activation, B cells and T cells leave a lasting legacy of the antigens they have encountered, in the form of memory cells. Throughout the lifetime of an animal these memory cells will "remember" each specific pathogen encountered, and are able to mount a strong and rapid response if the pathogen is detected again.
