Flashcards in Lec 12 - Cell Migration/Phagocytosis Deck (17):
1

all leukocytes can do this which is preferential migration of cells so they "know" how to get back

homing

2

first line of defense

neutrophils

3

a biochemical event that causes an increase in oxidative metabolism of phagocytes following uptake of opsonized particles

respiratory burst

4

t cell migration crosses cells by blank

diapedesis

5

unlike lymphocytes, neutrophils make a blank journey from bone marrow to tissue

one way

6

main contributor to inflammation

neutrophil

7

main contributor to chronic autoimmune reactions

cd4 T cells

8

main contributor to asthma

eosinophils, basophils, macrophages

9

toll like receptors can recognize these

LPS, bacterial flagellin, viral ss/ds RNA, bacterial dna

10

two types of adhesion molecules

integrins, selectins

11

homing receptor in lymphocyte circulation

L selectin

12

mediates adhesion of memory t cells and nk cells and neutrophils in response to inflammation

e selectin

13

this is involved in blood clotting

p selectin

14

all beta integrins share this

cd18

15

defect in cd18 causes this

leukocyte adherence deficiency

16

leukocyte adherence deficiency is life threatening due to blank

recurrent infections

17

these modulate adhesins

cytokines
