© 2018 Dr Lal PathLabs. Five serum samples recognized a 160-kd polypeptide, which comigrated with the band recognized by PF sera. These antibodies bind to calcium dependent adhesion molecules in cell surface desmosomes, notably desmoglein 1(DSG-1) in pemphigus foliaceus and desmoglein 3 (DSG-3) in pemphigus vulgaris. Autoantibodies in PF and PV recognize functionally important regions on Dsg and inhibit their adhesive function, leading to the loss of cell adhesion. For X-Ray, Ultrasound, ECG, TMT, Echo, PFT, Uroflowmetry reports please visit the concerned center where test has been conducted. In contrast, autoantibodies in HP may recognize a functionally less important part of the molecule and therefore are not able to induce loss of cell adhesion. Furthermore, immunoadsorption study results excluded a possibility that there are any autoantibodies reacting with molecules on keratinocyte cell surfaces other than Dsg1 or Dsg3 in 19 of 20 HP serum samples. Serum samples from patients with HP were analyzed by immunoblotting, ELISA with rDsg1 and rDsg3, and immunoadsorption assay. TShimizu
First, IgG fractions prepared from patients with PF and PV can induce blisters in skin organ culture and in neonatal mice.25-27 Second, removal of anti-Dsg1 or anti-Dsg3 autoantibodies from PF or PV sera, respectively, abolished the ability of the sera to induce blister formation in neonatal mice.18,19 Third, Dsg1 and Dsg3 are expressed in the epidermis, where blister formation occurs in PF and PV, respectively.21 At present, the distinct pathophysiological events responsible for these differences are unknown.
