antigen
Tolerance exists when the immune system does not respond to a particular antigen. All cells and tissues in the body contain antigens that normally do not stimulate an immune response. The immune system is said to exhibit tolerance toward such antigens.
When an antigen and its matching antibody meet in the body, the antibody binds to the antigen, marking it for destruction by the immune system. This process helps to neutralize the antigen and prevent further harm to the body.
One term that is used is antigen. An antiGEN will GENerate an ANTIbody which will 'kill' the antigen.
An antigen are the germs that enter the body, and antibodies are the thing that the body produces to kill them.
antigen
Its the antigen in a particular foreign body or pathogen that the body recognizes as "allo" or unfamiliar.. Maybe even harmful. So antibodies are produced against these antigens. And since they are 'neutralizing antibodies' it follows that the antigens they bind to are 'neutralizing antigens'
Yes that is true, and they only attach to a non-self antigen, that is, an antigen not produced in the body. and they only attach to certain antigens
when a antigen enters the body then the body would send antibodies to get rid of them. The antibody doesn't get rid of the antigen they tag it by binding to it so that a cell..a white blood cell can come and destroy by phagi.
it specifically recognise the antigenic determinants called epitopes and the similar sequence of that particular epitope will be produced by the antibody at is variable region(specifically hypervariable region) whch make an antibody to get more affinity over that particular antigen..almost antibodies are available for almost all the antigens in our body(memory cells)and they starts increasing in numbr once an antigen enters our body
Basically to explain this, an antigen is any type of pathogen that causes disease, while an antibody is something that combats against the antigen.
When an antibody attaches onto an antigen it destroys the antigen to help your body fight off a disease.
