What else can I help you with?
Is T cell activation antigen specific?
Yes. The first signal that a T cell receives from an antigen presenting cell (dendritic cell) is MHC presenting an antigen (foreign peptide). This gives the T cell specificity to this antigen.
What occurs if a T cell binds to an antigen and the T cell does not receive a co-stimulatory signal?
The T cell enters a state of anergy. In this case, the T cell becomes tolerant to that antigen and is unable to divide or to secrete cytokines. This state of unresponsiveness to antigen is called anergy.
What type of cell makes blood cells?
antigen
What happens when a B cell recognize an antigen?
When a B cell recognizes an antigen, it will undergo activation and differentiation into plasma cells, which produce antibodies specific to that antigen. Some B cells may also differentiate into memory cells that provide long-lasting immunity to the antigen. This process is essential in the adaptive immune response to eliminate pathogens and prevent future infections.
What Red blood cell antigen named after the rhesus monkey?
The red blood cell antigen named after the rhesus monkey is the Rh factor or Rh antigen. It is an important antigen in blood transfusions and plays a role in hemolytic diseases of the newborn when an Rh-negative mother carries an Rh-positive fetus.
This cell speeds up the recognition of an antigen when it is introduced again after an initial exposure and reaction?
Phagocyte
Is T cell activation antigen specific?
Yes. The first signal that a T cell receives from an antigen presenting cell (dendritic cell) is MHC presenting an antigen (foreign peptide). This gives the T cell specificity to this antigen.
The immune cell that allows for subsequent recognition of an antigen resulting in a secondary response is called an?
Memory cell. Memory cells are a type of immune cell that remember specific antigens upon initial exposure, allowing for a faster and more effective response upon subsequent exposure to the same antigen.
What area is antigen challenge and clonal selection most likely to occur?
Antigen challenge and clonal selection are most likely to occur in the secondary lymphoid organs, such as the lymph nodes and spleen. These organs are where antigens encounter immune cells, triggering an immune response and the selection of specific immune cell clones.
What do dendrictic cell do?
antigen processing and presentation

Which cell is known as antigen presenting cell?
Dendritic cells,macrophages, B cells
What Red blood cell antigen named after the rhesus monkey?
The red blood cell antigen named after the rhesus monkey is the Rh factor or Rh antigen. It is an important antigen in blood transfusions and plays a role in hemolytic diseases of the newborn when an Rh-negative mother carries an Rh-positive fetus.
Where would a B cell not be likely to meet its antigen?
spleen
What is an effector cell?
The effector cell responds to a nerve impulse and can be either a muscle cell or a gland cell.
