Calcium-sensing receptor-mediated NLRP3 inflammasome response to calciprotein particles drives inflammation in rheumatoid arthritis

How extracellular calcium can trigger Nlrp3 inflammasome activation has been somewhat controversial and unclear. Here the authors show calciprotein particles are taken up by myeloid cells via calcium-sensing receptor-dependent macropinocytosis in response to high levels of extracellular Ca2+ and thi...

Sumario:How extracellular calcium can trigger Nlrp3 inflammasome activation has been somewhat controversial and unclear. Here the authors show calciprotein particles are taken up by myeloid cells via calcium-sensing receptor-dependent macropinocytosis in response to high levels of extracellular Ca2+ and this pathway might be critical to inflammatory conditions.
