Stimulation of carbonic anhydrase in osteoclasts by parathyroid hormone.

abstract：:Patients with systemic lupus erythematosus (SLE), a chronic inflammatory disease characterized by loss of T- and B-cell tolerance to autoantigens, are at increased risk for osteoporosis and fractures. Mice deficient in Fc gamma receptor IIb (FcγRIIB) exhibit spontaneous SLE and its restoration rescues the disease. To ...
