in part, by your body activating the immune system’s white blood cells to fight off illness-causing bacteria and viruses.
Inflammation is caused,
find their way to foreign invaders by following a “trail” of molecules called S1Ps.
White blood cells
S1Ps lead white blood cells to the bowel, where they release proteins that trigger inflammation.
In people with ulcerative colitis,
block the receptors on white blood cells that respond to S1P. This “blindfolds” the white blood cells so they can’t follow the S1P trail.
S1P receptor modulators
don’t go to your gut, inflammation subsides and ulcerative colitis symptoms improve.
Because white blood cells
