What is term for the molecule on the surface of a virus tht is recongnized by the immune system?
The molecule on the surface of a virus that is recognized by the immune system is called an antigen. Antigens can be proteins or polysaccharides and are crucial for triggering an immune response, allowing the body to identify and combat the virus.
What is foreign molecule?
A foreign molecule is a substance that is not naturally produced or recognized by the body. When foreign molecules enter the body, the immune system may identify them as threats and initiate an immune response to protect the body from potential harm.
Define the term of antigen?
An antigen is a substance/molecule that, when introduced into the body, triggers the production of an antibody by the immune system, which will then kill or neutralize the antigen that is recognized as a foreign and potentially harmful invader.
Is a CD4 molecule also a type of antigen?
No, a CD4 molecule is not an antigen. CD4 is a protein found on the surface of helper T cells, a type of immune cell that plays a crucial role in the adaptive immune response by helping to coordinate immune responses. Antigens are molecules that can be recognized by the immune system, such as proteins on the surface of pathogens or foreign substances.
Is an antigen a white blood cell?
An antigen is a molecule recognized by the immune system. (Wikipedia)For the source and more detailed information concerning your request, click under the related links section (Wikipedia) indicated directly below this answer section.
How does antigen work?
An antigen is a substance or molecule that, when introduced into the body, triggers the production of an antibody by the immune system, which will then kill or neutralize the antigen that is recognized as a foreign and potentially harmful invader. These invaders can be molecules such as pollen or cells such as bacteria.
How has the flu virus found a way around the immune system?
It mutates itself so that it is no longer recognized by the immune system as an invader that it has previously killed and knows how to respond. It does this by rearranging the proteins on its coat (capsid).
Is a virus an antigen?
Yes, a virus contains antigens that can trigger an immune response in the body. Antigens are molecules on the surface of pathogens (such as viruses) that are recognized by the immune system.
Does the immune system attack Alzheimer's?
A commonly recognized cause of Alzheimer's is inflammation of a protein, called amyloid, that is found in the brain. The immune system senses this inflammation, though it is not entirely effective in reducing the inflammation and conquering the disease.
A marker molecule on a cell that the immune system uses to recognize a pathogen?
The major histocompatibility complex (MHC) molecules are marker molecules on cells that the immune system uses to recognize pathogens. MHC molecules present fragments of pathogens on the cell surface to alert immune cells to the presence of the pathogen. This helps the immune system to target and eliminate infected cells.
What is the molecule found on the outer surfaces of cells that the immune system recognizes as either part of the body or an outsides invader?
receptors
What system protects the body against infection?
your immune system and your White blood cells produce antibodies
