parathyroid hormone ( pth ) release and cytoplasmic ca2+ concentrations ( ca2+i ) of dispersed cells from the pathological parathyroid glands had right-shifted dependencies on extracellular ca2+ , and exposure to the antibodies rendered both ca2+i and pth release almost completely insensitive to changes in ambient ca2+ .
