Let's start with the first phrase:
"All immunogens are antigens"
Yes, that's true. Immunogens are antigens that CAN ELICIT IMMUNE RESPONSE and percieved as foreign by the body. Remember, anything that is percieved by the body as foreign is an antigen. Period.
Now the second phrase:
"All antigens are not immunogens"
This is also true. There are antigens, percieved by the body as foreign that CANNOT ELICIT IMMUNE RESPONSE. Example of this is Hapten Molecule. It is an antigen that cannot elicit response by itself, unless paired with a larger protein.
In summary:
Immunogens - form of antigens that can elicit response.
Antigens - anything percieved by the body as foreign that can either elicit or not (Hapten molecule) an Immune response.

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).
Do all bacteria have antigens if so what would happen if it entered your system?
yes they do
What medical term specialized white blood cells that produce antibodies coded to specific antigens?
all wbc produce antibodies to attach the the pathogens antigens.
Do genes for all possible antigens already exist in the body cells and can be just switched on to produce a particular antibody?
There can be billions types of possible antigens and only 20,000 to 25,000 genes are present in body. So the answer is NO.
What are molecules on the outer surface of a cell that identify it as long friend or for?
Molecules on the outer surface of a cell that identify it as "self" or "foreign" are called antigens. These antigens play a crucial role in the cell's ability to distinguish between its own cells and potentially harmful foreign cells. The recognition of self-antigens helps the immune system to tolerate the body's own cells while identifying and attacking foreign invaders.
Differences between immunogen and antigen?
An Antigen is considered as any foreign particle that enters the body such as dust, food and any microorganisms. An Immunogen is any foreign particle that triggers an response from the body's immune system. Consequently, all Immunogens are Antigens, but not all Antigens are Immunogens. To be considered an Immunogen, the particle has to have all the following characteristics: 1- Has enough atomic mass to be recognized by T cells and Antigen Presenting cells 2- Be significantly different from all of our cells or metabolites. 3- Must have a defined secondary and tertiary structure (has to be firm to form an epitope) 4- Has to be an antigen eg: Carbohydrates are not a highly immunogenic antigen, since they are made of glucose which is essential for our body's metabolism. Moreover, our body has the ability to store glucose as glycogen. An Adjuvant is a compound that increases the immunogenicy of antigens when mixed together.
What is the difference between antigen and immunogen?
Any foreign particle interact with Antibody or T cell is antigen. Interaction is non-covalent and highly specific. Antigen that evoke immune response is called Immunogen. An immunogen usually has a fairly high molecular weight (usually greater than 10,000), thus, a variety of macromolecules such as proteins,lipoproteins, polysaccharides, some nucleic acids, and certain of the teichoic acids, can act as immunogens.
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).
What do macrophages inflected body cells and virus particles all display?
Antigens
Do all bacteria have antigens if so what would happen if it entered your system?
yes they do
Why is type O considered the "universal donor"?
A type A blood sample contains A antigens which will conflict with any sample that does not have A antigens (B, O). O contains no antigens and therefore is compatible with all blood types.
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
Can mother ab and father o have o babies?
No, they cannot, the child will either have A antigens, B antigens or AB antigens The answer above may be correct, but it is impossible to check all blood types of couples who will get married. (JW70), (Moreover, I think it is not correct.)
What medical term specialized white blood cells that produce antibodies coded to specific antigens?
all wbc produce antibodies to attach the the pathogens antigens.
What is a histocompatibility antigen?
Histocompatibility antigens are molecules on the surface of all cells in the body. The specific types of histocompatibility antigens present on a person's cells determine their identity and distinguish each person. They are a "fingerprint."
Do genes for all possible antigens already exist in the body cells and can be just switched on to produce a particular antibody?
There can be billions types of possible antigens and only 20,000 to 25,000 genes are present in body. So the answer is NO.
What happens to an antigen-antibody complex?
The antigen grows a memory cell instead of the Plasma cell and takes over the whole body and kills all of the antibodies.
