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:
“We as women know that there are no disembodied processes; that all history originates in human flesh; that all oppression is inflicted by the body of one against the body of another; that all social change is built on the bone and muscle, and out of the flesh and blood, of human creators.”
—Andrea Dworkin (b. 1946)
“Here lies the body of William Jones
Who all his life collected bones,
Till Death, that grim and boney spectre,
That universal bone collector,
Boned old Jones, so neat and tidy,
And here he lies, all bona fide.”
—Anonymous. “Epitaph on William Jones,” from Eleanor Broughton’s Varia (1925)
“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.”
—Anne Sexton (1928–1974)
