Is sperm considered as antigen at the time of fertilization?
No, sperm is not considered an antigen at the time of fertilization. Antigens are substances that the immune system recognizes as foreign and can trigger an immune response. Sperm is a normal component of reproduction and does not elicit an immune response during fertilization.
What foreign substance elicits an immune response?
Any sort of "foreign" substance can, and most often will, elicit an immune response under certain curcumstances--provided the immune system is healthy. This would include bacteria, viruses and fungi. Related: An unhealthy, or compromised immune system can act in all sorts of undesirable ways, ranging from low response to threat or injury to actually creating antibodies to attack its own system or other organs and tissue.
How interferon drug work?
The exact molecular details of how interferons act is still unclear. They may make surface-exposed antigens of tumors even more capable of stimulating the immune system, which in turn would elicit a greater response from the T-cells of the immune system
What is a dead form of a pathogen that causes the immune system to react?
A dead form of a pathogen that stimulates an immune response is known as an inactivated or killed vaccine. These vaccines contain pathogens that have been killed or inactivated so they cannot cause disease but are still able to elicit an immune response. This process helps the immune system recognize and remember the pathogen, providing protection against future infections. Examples include the polio vaccine and the hepatitis A vaccine.
What is a system that fights disease and controls the immune response?
It is called the Immune System. A bit of extra info: The Immune System is the cause of allergies. It goes too far when trying to protect the body from something. ENDOCRINE SYSTEM
Why is a transplant consisting of fetal tissue less likely to provoke an immune rejection response than tissue from an adult?
Fetal tissue has lower levels of antigens, which are markers that the immune system recognizes as foreign. This makes fetal tissue less likely to provoke an immune response compared to adult tissue, which has a higher amount of antigens. Fetal tissue also has a higher ability to induce immune tolerance.
What is the main cause behind psoriatic arthritis?
The main cause behind psoriatic arthritis is the immune system attacking healthy cells and tissue. Due to the abnormal response from the immune system it causes overproduction of skin cells and inflammation of the joints. It's not clear why the immune system responds like this but it is likely genetic and environmental factors have something to do with the response.
What system does antigen belong to?
Antigen is a component of the immune system. It can trigger an immune response in the body by interacting with antibodies or immune cells.
How are antibodies and antigens related in the immune response?
Antibodies are proteins produced by the immune system in response to antigens, which are foreign substances that trigger an immune response. Antibodies bind to antigens to help neutralize or eliminate them from the body, playing a crucial role in the immune response.
What is the role of complement system in immune response?
The role of a complement system in immune response is to make sure that no bad cells penetrate the immune system. A complement system of immunization might be a series of shots, like booster shots for immunizations.
What are response cells?
Response cells are cells that respond to the immune system and react to diseases.
Which cell of the immune system is absolutely required for an adaptive immune response?
T helper cells
