Know the kinetics of an immune response and how to explain immune response to parasite antigens and the development of immune memory.

Answer #1

Immunity is the ability of the system to react to anything foreign invading the system. It can be increase in temperature or swelling to make the system hostile for the invading organism. When a parasitic antigen invades the system, the body produces corresponding antibody.

When the antigen infects a system the body produces immunoglobins or Ig of various forms and helps to fight the invader. Once the antibodies are produced, the body keeps an account of the antigen which caused the production of antibody and the next attempt by the parasite is fought upon more quickly due to the memory of the previous instance.

This concept is primarily used for vaccination, in which the required antigen is passed in avirulent state. The body produces antibodies and this memory helps it to fight the actual invasion of the parasite , if any in future.

A host organism needs time, often days, to mount an immune response against a new antigen, but memory cells permit a rapid response to pathogens previously encountered. A vaccine to protect against a particular viral infection often consists of weakened or killed virus or isolated proteins from a viral protein coat. When injected into a person, the vaccine generally does not cause an infection and illness, but it effectively teaches the immune system what the viral particles look like, stimulating...

What specific challenge does  Trypanosoma brucei present to the immune system? It frequently changes its antigens, staying one step ahead of the host's antibody response. It specifically attacks B lymphocytes preventing activation and antibody production. It specifically attacks T lymphocytes preventing their activation and crippling the cell-mediated immune response. Its antigens are not recognized by B and T lymphocytes so these host defense cells don't respond to the infection.
