Question 2

antigens inlcude

Answer 2

proteins, DNA, CHO and some lipids

Question 3

immunogens

Answer 3

antigens that induce an adaptive immune response

Question 4

the adaptive immune system targets infections

Answer 4

inside cells (bacteria/virus), inside macrophages (Mycobacterium), outside cells (bacteria/viruses/exotoxins)

Question 5

how is adaptive immunity specific compared to innate

Answer 5

each pathogen is targeted separately

Question 6

how is adaptive immunity diverse compared to innate

Answer 6

millions of diff B and T cells

Question 7

how is adaptive immunity self-tolerant compared to innate

Answer 7

system eliminates self-reactive B and T cells

Question 8

how is adaptive immunity inducible compared to innate

Answer 8

only T and B cells required to fight a particular infection will respond

Question 9

how does adaptive immunity have memory compared to innate

Answer 9

any B and T cells that have responded to an infection will produce memory B and T cells with same specificity. these cells respond quickly if you get the same infection again
