Function preservation1

  • Mechanical history may uncouple calcium entry from chloride flow within sweat-gland cells

    Where this hypothesis actsSweat gland secretory cells with persistent functional defects after mechanical loading

    What is proposedRestore calcium entry and calcium-dependent chloride conductance in the same cells

    With whatNot stated in the record

    HowCorrect both functions in the same cells, initially in a mosaic organotypic gland model, with mechanical load and duct patency matched

    Possible resultExpected stronger recovery of primary sweat secretion and stabilization of the sweat component of SPV_8
