Regulation of Osteoclast Activity: A New Approach in the Therapy of Bone Diseases
Regulace aktivity osteoklastů: prostor pro terapii některých onemocnění kostí
Kostní tkáň představuje dynamický systém, který velmi citlivě reaguje na podněty vnějšího prostředí i potřeby organizmu. Řada závažných onemocnění, která jsou spojena s poruchami v rovnováze mezi resorpcí a novotvorbou kostní tkáně, sdílí společný problém, kterým je abnormální stimulace diferenciace, funkce nebo aktivity osteoklastů. Pokrok v osteoimunologii a molekulární biologii objasnil řadu kontrolních mechanizmů řídících diferenciaci osteoklastů, jejichž znalost může umožnit potenciální terapii některých dosud obtížně léčitelných onemocnění.
Klíčová slova:
osteoklasty, diferenciace, aktivita, osteoporóza, terapie.

Overview
Bone remodelling is process of constant resorption and formation of a bone. Osteoclasts are the cells responsible for bone resorption. Deregulation of osteoclast differentiation, activity or function can cause severe diseases, such as osteoporosis, osteopetrosis or rheumatoid arthritis. Advances in molecular biology of osteoclasts and osteoimmunology open new approaches for the specific and efficient therapy.
Key words:
osteoclasts, differentiation, activity, osteoporosis, therapy.
