Секреция ПТГ регулируется посредством кальций-чувствительного рецептора (КЧР), преимущественно располагающегося на поверхности клеток околощитовидных желез и почечных канальцев. Активация КЧР происходит при повышении уровня кальция в организме и направлена на ингибирование синтеза ПТГ и усиление экскреции кальция с мочой, т.е. на защиту организма от неблагоприятного воздействия гиперкальциемии. Снижение экспрессии и/или изменение работы КЧР приводит к нарушению регуляции синтеза ПТГ и лежит в основе развития таких заболеваний, как первичный и вторичный гиперпаратиреоз, а также в ряде наследственных заболеваний, связанных с нарушением кальциевого гомеостаза. В данной работе рассмотрены функции КЧР в норме, а также обсуждаются потенциальные механизмы нарушения чувствительности КЧР при различных патологиях.</p></abstract><trans-abstract xml:lang="en"><p>Parathyroid hormone (PTH) plays a key role in the regulation of calcium-phosphate metabolism. The secretion of PTH is regulated by calcium-sensing receptor (CaSR), which primarily expressed in the parathyroid glands and the renal tubules of the kidney. Increase of calcium concentration in extracellular matrix of cells is causing activation of the CaSR. Activated CaSR inhibits secretion of PTH and increases urinary calcium excretion. All CaSR effects leads to prevent development of hypercalcemia complications. Downregulation of the CASR expression and/or altered CaSR functioning leads to dysregulation of PTH synthesis. It may be the underlying cause of the development of primary and secondary hyperparathyroidism, as well as a number of hereditary diseases associated with loss- and gain-of-function mutations of the CaSR. In this paper we discusses the function of the CaSR in physiology and also the potential mechanisms that can impaired CaSR-induced signaling in various calcitropic diseases.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кальций-чувствительный рецептор</kwd><kwd>паратиреоидный гормон</kwd><kwd>первичный гиперпаратиреоз</kwd><kwd>вторичный гиперпаратиреоз</kwd><kwd>фактор роста фибробластов 23</kwd><kwd>Клото</kwd></kwd-group><kwd-group xml:lang="en"><kwd>calcium-sensing receptor</kwd><kwd>parathyroid hormone</kwd><kwd>primary hyperparathyroidism</kwd><kwd>secondary hyperparathyroidism</kwd><kwd>fibroblast growth factor 23</kwd><kwd>Klotho</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Sundararaman SS, van der Vorst EPC.
