What kind of cells activate the immune system when foreign substances appear?
Cells called antigen-presenting cells, such as dendritic cells and macrophages, play a key role in activating the immune system when foreign substances appear. These cells identify and capture foreign antigens, present them to T cells, and help initiate an immune response.
What are the three pathways, including the alternative, classical, and lectin pathways, that activate the immune system's response to what?
The three pathways that activate the immune system's response are the alternative, classical, and lectin pathways. They work together to recognize and respond to foreign invaders, such as pathogens or damaged cells, in the body.
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.
When an antigen is bound to a class II MHC protein it can activate what cell?
When an antigen is bound to a class II MHC protein, it can activate helper T cells. Helper T cells play a critical role in initiating and coordinating immune responses by releasing various signaling molecules and activating other immune cells.
What kind of cells activate immune system and foreign substances appear?
Immune system activation primarily involves dendritic cells and macrophages, which are types of antigen-presenting cells (APCs). These cells capture and process foreign substances, such as pathogens, and present their antigens to T cells. This interaction activates T cells, which then help coordinate the immune response by signaling other immune cells, including B cells that produce antibodies. Together, these cells work to identify and eliminate foreign invaders.
Which system does a flu shot activate?
Immune System
Which cell activate the immune system?
T cells
Which system is to prevent foreign substances from entering the body to attack foreign substances that are in the body?
The Immune System is the defense network of the body. The immune system works with specific receptors on specialized cells - detecting foreign bodies and signaling for the immune system to destroy them.
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
