Acquired immunodeficiency syndrome (AIDS) is a destruction of the immune system caused by a viral infection (HIV). It usually takes decades from the time of original infection before the virus actually begins destroying the immune system, but once it starts the victim rapidly looses the ability to fight off not only pathogens, but very rare cancers, as well as organisms that usually live harmlessly (and even sometimes symbiotically with our bodies) on or in our bodies.
Without treatment to stop replication of the virus acquired immunodeficiency syndrome (AIDS) is always fatal, with treatment many victims can live a nearly normal lifespan.
Not exactly, It is caused because the HIV virus which causes the disease AIDs attack the cells that would should have responded and inactivated the virus. That is the response you body has when you get a cold.
This nasty virus destroys the bullets you need in your guns so you can't inactive them like them like you do with a simple cold. Your body tries but can't.
Notice the use of the term "killed" is not used as these are viruses and they are not alive.
Multiple sclerosis

It isn't; it is your immune system working properly. The problem is your immune system is firing against a toxin that is lodged in your own body's tissues. When the toxin (now called an antigen) cannot die, your immune system becomes Th1 or Th2 dominant.
adaptive immune response
Yes i think they do
destruction of bacteria by lysozme
No Rheumatoid arthritis is an autoimmune disease that results in the immune system mistakenly attacking (among other tissues of the body) cartilage in the synovial joints. This leads to further destructive chemicals being created which in turn destroys further tissue in an around the joints. there is arthritis that has a connection with infection and RA may have some reaction there however RA is not seen as being the result of any pathogen.
Immunity.
This is the hypersensitivity to a drug or other substance without any relation with thr immunological response.
