Bone
The endocannabinoid system through CB2 signaling plays a key role in the maintenance of bone mass. CB2 is expressed in osteoblasts, osteocytes, and osteoclasts. CB2 agonists enhance endocortical osteoblast number and activity while restraining trabecular osteoclastogenesis. Another important effect is that CB2 agonists attenuates ovariectomy-induced bone loss while increasing cortical thickness. These findings suggest CB2 offers a potential molecular target for the diagnosis and treatment of osteoporosis.

Famous quotes containing the word bone:
“You must be wise, in order to sniff out and weigh these mighty books, and swift in the hunt and brave in the battle; then, by careful reading and frequent reflection, crack open the bone and suck out the substantific marrow.”
—François Rabelais (1494–1553)
“Take adultery or theft.
Merely sins.
It is evil who dines on the soul,
stretching out its long bone tongue.
It is evil who tweezers my heart,
picking out its atomic worms.”

“the bone dry voices of the peepers
as they throb like advertisements.”
