Anti...what?
(-gen, -body, -biotic)
(-gen, -body, -biotic)
This is a substance on the surface of a pathogen that triggers an immune response.
What is an antigen?
This model explains why only certain molecules can bind to certain receptors.
What is the lock-and-key model?
This occurs when the immune system overreacts to a harmless substance
What is an allergy?
These are the smallest pathogens and require a host cell to reproduce.
What are viruses?
This introduces a weakened or inactive (dead) pathogen to trigger immunity.
What is a vaccine?
These Y-shaped proteins are produced by B cells, a type of white blood cell, to fight specific invaders.
What are antibodies?
This is the specific shape on a cell membrane that a chemical messenger binds to.
What is a receptor?
Sneezing, itching, and watery eyes are common symptoms of this immune response.
What is an allergic reaction?
Strep throat is caused by this type of pathogen. (Hint: you can take an antibiotic to fight it off.)
What are bacteria?
These cells remember pathogens and allow for a faster response later.
What are memory cells?
This is used to treat bacterial infections but does NOT work on viruses.
What is an antibiotic?
Antibodies must match the shape of this structure on a pathogen.
What is an antigen?
This virus attacks helper T cells, a type of white blood cell, and weakens the immune system.
What is HIV?
This pathogen causes athlete’s foot and other fungal infections.
What are fungi?
Once infected, your body responds by doing this.
What is produce antibodies?
This binds to an antigen like a lock and key to help destroy pathogens.
What is an antibody?
If a hormone or signal cannot bind to its receptor, this will NOT occur.
What is cell activation (or a cell response)?
This fully developed condition makes the body unable to fight off infections effectively.
What is AIDS?
This type of pathogen is treated with antibiotics.
What are bacteria?
Taking a vaccine before infection allows the immune system to do this more quickly if exposed later.
What is recognize and fight the pathogen faster?
Penicillin is an example of this type of medical treatment.
What is an antibiotic?
This explains why the immune system can target one pathogen without harming others.
What is shape specificity? (They have a specific shape!)
This type of disease occurs when the immune system attacks the body’s own cells.
What is an autoimmune disease?
This “pathogen” is NOT alive but can still cause disease.
What is a virus?
Vaccines are taken before illness so the body can do this before encountering the real pathogen.
What is produce antibodies (or develop immunity)?
