18
Q

immune system LDL steps

A
  1. cytokines oxidize LDL particles
  2. oxidized LDL particles are internalized by macrophages –> become foam cells
19
Q

3 steps of foam cell formation

A

capture
rolling
penetration

20
Q

foam cell formation: capture
__ capture by E-Selectins

A

foam cell formation: capture
leukocytes capture by E-Selectins

21
Q

foam cell formation: rolling
__ rolling, activation of __, adhesion to __
this all increases endothelial __

A

foam cell formation: rolling
leukocyte rolling, activation of chemokines, adhesion to endothelial cells
this all increases endothelial permeability

22
Q

foam cell formation: penetration
__ penetrates arterial intima

A

foam cell formation: penetration
monocyte penetrates arterial intima

23
Q

final step of foam cell formation
monocyte uptakes __ molecules via __ receptors and forms __ on __ wall

A

final step of foam cell formation
monocyte uptakes LDL molecules via scavenger receptors and forms plaque on arterial wall

24
Q

pathways that activate __ expression affect atherosclerosis by __ inflammation

A

pathways that activate NF-kB expression affect atherosclerosis by increasing inflammation

25
Q

characteristics of vulnerable plaques

A

thickening and accumulation of lipids and foam cells –> rupture
