Foreign organic or inorganic materials, such as viral/bacteria proteins, bacteria toxins, parasites membranes, foreign objects, etc. Incompatible blood or organs are perceived as antigenic as well, that's why they make all those compatibility tests before a transplant.
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.
Yes, pollen can act as an antigen by triggering an immune response in the body. When someone with allergies inhales pollen, their immune system may mistakenly perceive it as a threat and produce antibodies against it, leading to symptoms such as sneezing, itching, and congestion.
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
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.
antigen
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.
An antigen is a substance that triggers an immune response in the body, by stimulating the production of antibodies. This response helps the body to recognize and destroy harmful pathogens such as bacteria, viruses, or foreign substances.
Rh is an antigen that your blood either does (+ type) or does not have (- type). These are not compatible with each other as the antigen in a body without is rejected by the body.
