Antibodies attach to specific proteins on the surface of pathogens, called antigens, to help neutralize and eliminate them from the body.
Looking for antigens is part of a specific immune response.
The classical pathway is part of the adaptive immune response and is triggered by specific antibodies binding to pathogens. The alternative pathway is part of the innate immune response and is activated by the presence of foreign substances on the surface of pathogens.
When your body feels threatened by germs, it produces white blood cells, antibodies, and cytokines as part of your immune response to help fight off the infection.
Memory B cells are a characteristic part of the secondary immune response. They are formed during the primary immune response and can quickly recognize and respond to a previously encountered antigen by producing antibodies. This results in a faster and more robust immune response upon subsequent exposure to the same antigen.
Nonspecific like the skin, mucous membranes, tears, mucus and the inflammatory response... are designed with and acidic surface that, for the most part, repels bacteria and are attributable to factors other than specific antibodies. They are often called innate immunities. Specific immunity has to do with how our lymphocytes (specialized white blood cells, such as B and T Cells) that can remember a specific virus or bacteria, and the next time it shows up, there's a whole welcoming party ready with lots of demolition gear to destroy the unwelcome guests.
Actigen refers to a specific substance that can provoke an immune response, often a part of a pathogen like bacteria or viruses. Antibodies are proteins produced by the immune system in response to antigens; they recognize and bind to specific antigens to neutralize or mark them for destruction by other immune cells. Together, actigens and antibodies play crucial roles in the body’s defense against infections.
The part of the immune response that is specific to a particular pathogen is the adaptive immune response. This response involves the activation of lymphocytes, particularly T cells and B cells, which recognize specific antigens presented by the pathogen. B cells produce antibodies that target these antigens, while T cells can directly kill infected cells or help orchestrate the immune response. This specificity allows for a tailored and effective defense against distinct pathogens.
antibodies
Antibodies (also known as immunoglobulins, abbreviated Ig) are gamma globulin proteinsthat are found in blood or other bodily fluids of vertebrates, and are used by the immune system to identify and neutralize foreign objects, such as bacteria and viruses..
An antigen is a substance that can trigger an immune response in the body, such as proteins on the surface of bacteria or viruses. A pathogen, on the other hand, is a type of antigen that can cause disease in the host organism by invading and damaging tissues. Not all antigens are pathogens, but all pathogens are antigens.
Vaccines are the primary solutions that contain all or part of a harmless version of a pathogen. They often include inactivated or attenuated forms of the pathogen, or specific proteins or pieces of genetic material that stimulate an immune response without causing disease. Other examples include certain therapeutic treatments, like monoclonal antibodies, which may utilize harmless components of pathogens to target and neutralize infections. These solutions help the immune system recognize and fight off the actual pathogen if encountered in the future.
lymphocytes make antibodies by first getting the antigen marker from a pathogen. Then, using a 'toolkit' of various protein fragments, they use the marker as a 'blueprint' to make the antibody.
Antibodies are biomolecules that have a Y-shaped structure. This Y shape allows antibodies to bind to specific antigens, recognizing and neutralizing them as part of the immune response.
It is a non-specific Immune response as it does not change based on interaction with a pathogen and will activate regardless whether the pathogen in question has been encountered previously. Commonly referred to as being part of the "Second Line of Defence".
- Antibodies bind to the pathogen to prevent them from entering or damaging cells. - Antigens coat the pathogens stimulating the removal of pathogen by macrophages & other cells - They trigger destruction of pathogens by stimulating other immune response
