In the disease leukocyte adhesion deficiency, leukocytes cannot stop rolling at the site of a wound. Normally leukocytes are signaled through a pathway to activate to induce tight binding and eventually migration out of the vein.

Explanation:

GPCRs stands for G protein-coupled receptors and play important roles in inflammation.

Inflammation is a terminology in medicine that describes the condition of any part of the body, consisting of congestion of the blood vessels, with obstruction of the blood current, and growth of morbid tissue. It is manifested outwardly by redness and swelling, attended with heat and pain

Inflammatory cells like polymorphonuclear leukocytes (PMN), monocytes and macrophages is characterised by a large number of GPCRs for classic chemoattractants and chemokines.

An intergrins is any of many heterodimeric transmembrane proteins that function as receptors in communication between cells.

for me i have felt invisible when i was clearly struggling,or,i made a great achievement ,and,nobody took to notice me either because they just didn't see it,or,people just turned their back on me.i can see a person being invisible by choice,or,without choice like i did.the people who are invisible by choice don't try to talk to people,don't try to make friends,and,keep to themselves.i haven't been one of those people so i couldn't give you a reason.
