List the various types of cells involved in human immunity. Specify the function(s) of each. How do vaccines cause the production of antibodies? Why should mere absence of antibodies not be considered as absence of immunity against a particular pathogen ?
Answers
Answer:
These two cell types have different roles:
B lymphocytes — they produce antibodies and help alert the T lymphocytes.
T lymphocytes — they destroy compromised cells in the body and help alert other leukocytes.
An antigen specifically induces the production of antibodies which can bind to it and neutralise it. While most vaccines work by inducing B lymphocytes to produce antibodies (see below), activation of T-cells — another type of immune system cell that helps protect against disease — is also important for some vaccines.Vaccination increases the levels of circulating antibodies against a certain antigen. Antibodies are produced by a type of white blood cell (lymphocyte) called B cells. Each B cell can only produce antibodies against one specific epitope.Vaccines contain a harmless form of the bacteria or virus that causes the disease you are being immunised against. The bacteria or virus will be killed, greatly weakened, or broken down into small parts before use in the vaccine so that they can trigger an immune response without making you sick.
