All antigens are crucial when we talk about good health. These tiny molecules act as the security system of our body by identifying and reacting to foreign substances. Antigens help signal the immune response to bacteria, viruses, or non-living allergens. Understanding the types of antigens can greatly help you choose the right health insurance policies, too. Let’s explore antigen classification further.
Antigen Types
Here is a breakdown of the kinds of antigens present in our bodies:
- Exogenous antigens: These antigens enter the body from the skin, swallowing, or breathing. Typical ones are dietary proteins, pollen, and infections. We need to recognise these three types of antigens; they help the body fight infections and allergic reactions.
- Endogenous antigens: These antigens are produced from within. They arise from our bodies’ cells, especially when they get infected by viruses or become cancerous. Endogenous antigens signal the immune system to fight internal threats and essentially mark cells for destruction.
- Autoantigens: In some circumstances, the immune system mistakenly attacks healthy cells as threats. This reaction causes autoimmune illnesses, in which the body destroys its own tissues.
- Tumour antigens: These are associated with cancer cells. As cells turn cancerous, they express new or altered antigens that can sometimes be detected by the immune system.
- Native antigens: These are the regular and healthy proteins that are normally found in our body. They are regarded to be healthy and usually cause no immune reaction.
- Immunogens: These antigens can set off a strong immune response. It is absolutely necessary for immunisation to be effective.
- Hapten: These tiny molecules form a new antigenic structure when coupled with bigger proteins. They are capable of setting off an immune reaction.
Conclusion
Antigens play a crucial role in our health. These microscopic entities have a significant impact. They act as friend and foe. Knowing about them helps us understand our bodies better. However, it is advisable to get health insurance to cover medical expenses.
