Task: Answer Verification
Input (English): Question: Are antibodies to the amino-terminal domain of desmoglein 1 retained during transition from pemphigus vulgaris to pemphigus foliaceus?
Answer: Our findings suggest that amino-terminal pathogenic antibodies to the EC domain of Dsg1 were retained, while considerable epitope changes occurred in response to Dsg3 during the shift from PV to PF, with an absolute or significant decrease in pathogenic antibodies to the EC1 domain of Dsg3.
Output (English): yes
