Macrophages ( in the lymph nodes ) act like phagocytes to engulf and digest the pathogen. But they do not fully digest it. They separate out the antigens and incorporate them into a cell surface molecule. This is exposed on the surface of the macrophage, which becomes known as an antigen-presenting cell. Its function is to find the lymphocytes that can neutralise that particular antigen.

What typoes of cells produce antigens?
All cells produce antigens, or cell surface markers. The only question is whether the antigens are self antigens which means they belong in the body or they're foreign antigens which means they are an invading bacteria or virus (or a cancerous cell).
Serological testing is based on the fact that antibodies react specifically with an anigen all bacteria have the same antigens or the human body makes antibodies against bacteria?
AnswerThe human body makes specific antibodies to specific antigens (ex. proteins on a bacterial membrane) that it encounters. Bacteria do not all have the same antigens.* antibodies react specifically with an antigen
Do all bacteria have antigens if so what would happen if it entered your system?
yes they do
Can plasmids or bacteriophages be used in vaccines to fight bacteria?
Yes, plasmids can be used in DNA vaccines to fight bacteria by expressing antigens that trigger an immune response. Bacteriophages can also potentially be used in vaccines by delivering antigens or genes into host cells to stimulate an immune response against bacteria.
What is a foreign chemical that stimulates the production of antibodies?
An antigen is a foreign chemical that stimulates the production of antibodies by the immune system. Antigens can be bacteria, viruses, toxins, or other substances that are recognized as foreign by the body.
What is the use of genetically engineered bacteria?
The can produce antigens useful in making vaccines without the harmful parts of the original disease organism.
How many antigens are there in the human body?
There is no definite number of antigens in the human body as the immune system can recognize a wide range of foreign substances. Antigens can come from pathogens like bacteria and viruses, as well as from our own cells in cases of autoimmune diseases. The human body constantly encounters new antigens and can generate immune responses against them.
Where do antigens, the substances that trigger an immune response in the body, originate from?
Antigens, which trigger the immune response in the body, originate from foreign substances like bacteria, viruses, and other pathogens, as well as from the body's own cells that have been altered or damaged.
Antigen and antibody?
An antigen is a foreign particle that enters the body. This could be a disease causing agent such as part of a bacterium or virus or could be a particle such as pollen or dust. An antibody is a protein made by the body's immune system. Antibodies react with specific antigens to enable the antigens to be removed from the body.
Does sanitizing mean removal of harmful bacteria?
yes. sanitizing gets 99% of bacteria removed from your hands
What can prevent us from getting sick from antigens and bacteria?
Fill a glass with 1/3 cup of oil and 1/3 cup of vinegar. Drop in four quarters, fresh off the mint, and let sit for seven days. Take off your shoes and soak your middle toe in this liquid for three hours. Bacteria and Antigens will never bother you again.
Does Type B blood have A antigens?
No, type B blood does not have A antigens. Type B blood has B antigens.
