9 Questions
The body's immune system can remember past encounters with a pathogen and produce a faster and more effective response if exposed to the same pathogen again in the future due to the long-lived ______ created during initial exposure.
memory cells
The number of memory cells for a specific pathogen is regulated to maintain a stable number through a balance between cell death and ______.
cell proliferation
After smallpox vaccination, there is an initial peak in antibody levels, followed by a period of maintenance with no significant ______.
decline
• The body's immune system can produce a faster and more effective response to a pathogen upon a second encounter due to the creation of ______ during initial exposure
memory cells
• Memory cells for a specific pathogen are regulated to maintain a ______ between cell death and cell proliferation
balance
• After smallpox vaccination, memory T-cells last a long time but decay over time, with a half-life of ______
8-15 years
Memory cells are created during initial exposure to a pathogen and persist until the second encounter due to their
long-lived nature
The balance between cell death and cell proliferation in memory cells for a specific pathogen is regulated to maintain a
stable number
After smallpox vaccination, the immune system can still produce a robust response to smallpox even in the absence of new infections due to the presence of
memory cells
"Boost Your Knowledge on Immune System Memory Cells: How They Help Fight Pathogens!" Take this quiz and learn how the body's immune system remembers past encounters with pathogens, creating long-lived memory cells that produce a faster and more effective response upon future exposure. Test your understanding of the role of memory cells in fighting infections and how they replenish themselves. Get ready to enhance your understanding of immunology with this informative quiz!
