|
|
B cells would be unable to make antibodies until antigens are presented through macrophage MHCs
|
|
|
Antibodies would not exist until dendritic cells brought pathogens to the lymph nodes
|
|
|
Immunity would be at its highest because antibodies for this specific antigen have not yet been depleted
|
|
|
In order to make up for the deficit in B cell antibody production, helper and cytotoxic T cell production would increase
|
Detailed explanation-1: -Antibodies are produced by B cells (specialized white blood cells). When an antigen comes into contact with a B cell, it causes the B cell to divide and clone. These cloned B cells-or plasma cells-release millions of antibodies into your bloodstream and lymph system.
Detailed explanation-2: -Acquired immunity is immunity that develops with exposure to various antigens. Your immune system builds a defense against that specific antigen. Passive immunity is due to antibodies that are produced in a body other than your own.
Detailed explanation-3: -Impairing antigen presentation enables pathogens to hide given that in the absence of functional antigen presentation, T cells can no longer detect pathogen-derived antigen.
Detailed explanation-4: -The innate immune system is the body’s first line of defense against germs entering the body. It responds in the same way to all germs and foreign substances, which is why it is sometimes referred to as the “nonspecific” immune system.
Detailed explanation-5: -They are activated by antigen-presenting cells (like dendritic cells) that carry the foreign particles and pass them over so that the lymphocytes recognize them and destroy them or produce antibodies.
