How does bacteria outsmart your immune system?
bacteria outsmart the immune system by imitating other cells.
Which types of T cells are a critical component of the immune system because it stimulates and enhances the activity of other components of the immune system?
T -helper cells
What kind of cell does HIV infect?
HIV infects cells in the central nervous system and the immune system. HIV's main target cell is the T helper lymphocyte. These cells play a crucial role in the immune system, by coordinating the actions of other immune system cells. A large reduction in the number of T helper cells seriously weakens the immune system3
Is your immune system the white blood cells?
Yes, your immune system is a "team" of white blood cells that swallow other opposing cells or bacteria, and then destroy them. This process may destroy the blood cell.
How does your body know which cells to attack?
1. Your immune system can recognize cells based on the proteins present on the surface of cells. Viruses, bacteria, and other foreign cells are recognized as being different from your own cells and are attacked by your immune system.
Four of the five cells listed - viruses cells - MHC markers - cancer cells - bacteria - dead cells - are targets of the immune system - Select the exception?
MHC markers- which are proteins that present or "show" antigens like bacteria to other immune cells. Instead of being targets, they are helper proteins of the immune system.
Name 2 cellular components of the immune system capable of destroying other cells?
macrophages and T cells
How does the body know which cells to attack?
The body's immune system is able to distinguish between self and non-self cells through various mechanisms. One such mechanism is the presence of major histocompatibility complex (MHC) molecules on the surface of cells, which helps the immune system recognize self-cells. Non-self cells, such as infected or cancerous cells, may display abnormal proteins or antigens that are recognized as foreign by the immune system, prompting an immune response to attack and eliminate them.
Mobile immune system cells that engulf and digest bacteria and other microbes?
macrophages
Which T cell inhibits the activity of other T cells?
Regulatory T cells (Treg) suppress the action of other T cells. This inhibits immune responses to self-antigens, aiming to prevent the immune system from attacking normal self cells.
How is HIV different from other virus pathogens?
HIV is a retro virus, that infects your immune cells. The virus attaches to CD4 receptors on T-cell (the cells that are part of the immune system.)
What is the function of dendritic cells?
It provides exterior Form. It helps to Control what goes in and out of the CellDendritic cells are a type of immune cell found in the immune system of mammals. Their main role is processing antigen materials and delivery of these materials to surfaces of other cells.
