Why does a sperm doesn't act as foreign to induce immune response?
Sometimes the sperm does induce an immune response - some infertility problems are caused by women having anti-sperm antibodies which kill the sperm before it has the opportunity to fertilise the ova.
What activates helper T cells in the immune response?
Helper T cells in the immune response are activated by antigens presented by antigen-presenting cells, such as dendritic cells. This activation process helps coordinate and regulate the immune response against pathogens.
Which cell of the immune system is absolutely required for an adaptive immune response in that it helps activate both humoral and cellular immune responses?
Helper T cells
Why does the strength of immune response decline?
because the cilia helps clump demise together
What cell helps to direct the activities of all other cells during the immune response?
The cell that helps to direct the activities of all the other cells during the immune response is the white blood cell. It attacks the virus or bacteria first.
How do cytokines work to regulate the immune response in the body?
Cytokines are proteins that act as messengers in the immune system, helping to regulate and coordinate the body's response to infections and other challenges. They can stimulate or suppress immune responses by signaling to different immune cells. This helps to maintain a balanced and effective immune response, preventing overreactions or inadequate responses to threats.
What are the benefits of a fever for the body's immune response?
A fever can help the body's immune response by making it harder for bacteria and viruses to survive and reproduce. It also helps the immune system work more efficiently to fight off infections.
What are the benefits of fever for the body's immune response?
Fever helps the body's immune response by creating an environment that is less favorable for bacteria and viruses to thrive. It also activates the immune system to work more efficiently in fighting off infections.
Which hormone helps the body control stress regulate metabolism and influence an immune response?
Ephinephrine
What is the class of antibody first secreted in response to a new antigen?
IgM is the class of antibody first secreted in response to a new antigen. It is produced during the initial immune response and helps to activate other components of the immune system.
What essential role do antibodies play in the adaptive immune system and how do they contribute to immune response?
Antibodies are proteins produced by the immune system that help identify and neutralize harmful pathogens like viruses and bacteria. They play a crucial role in the adaptive immune response by recognizing specific antigens on these pathogens and marking them for destruction by other immune cells. This targeted response helps the body fight off infections more effectively.
How do macrophages in the skin contribute to the body's immune response against pathogens and foreign substances?
Macrophages in the skin play a key role in the body's immune response by engulfing and destroying pathogens and foreign substances. They also help to activate other immune cells and release signaling molecules to coordinate the overall immune response. This helps to protect the body from infections and maintain overall health.
