In conclusion, a thinner epidermis was found in CVI, which might be the result of the changes in expression of P2Y and P2X receptors on keratinocytes: that is, increased proliferation via P2Y(1) and P2Y(2) receptors and reduced P2X(7) receptor-mediated cell death opposed by a dominant decrease in cell numbers as a result...
