Immunity ( 54 Questions)
Which of the following is an essential step in antigen recognition during the immune response?
Activation of regulatory T cells is important for controlling and regulating the immune response but is not directly related to the antigen recognition process.
Production of histamines by mast cells is involved in the inflammatory response, but it is not a direct step in the antigen recognition process.
Antigen recognition during the immune response occurs when antigens bind to specific receptors on immune cells, such as B cell receptors, T cell receptors, or antibodies. This binding is a critical step that triggers the activation of the immune response against the invading pathogen or foreign substance.
Neutrophils are a type of white blood cell involved in the innate immune response. They do not release antibodies, as that function is primarily carried out by B cells and plasma cells.III. B Lymphocytes (B Cells) and Antibody-Mediated Immunity:
Explanation: Antigen recognition during the immune response occurs when antigens bind to specific receptors on immune cells, such as B cell receptors, T cell receptors, or antibodies. This binding is a critical step that triggers the activation of the immune response against the invading pathogen or foreign substance.
Incorrect choices:
a. Activation of regulatory T cells is important for controlling and regulating the immune response but is not directly related to the antigen recognition process.
b. Production of histamines by mast cells is involved in the inflammatory response, but it is not a direct step in the antigen recognition process.
d. Neutrophils are a type of white blood cell involved in the innate immune response. They do not release antibodies, as that function is primarily carried out by B cells and plasma cells.
