16.75 μg empirically tittered peptide mix needed to yield zero serum specific IgE level. |
Depicted is the expected, 10 minute intravascular half-life of the PLP epitope-mimicking peptide ADARM and the MOG-mimicking peptides, DHSYQE, and KTGQF. The ongoing, endogenous loss is likely to be caused by renal clearance and enzymatic degradation. The infused peptides would, thereby, complex with and neutralize their corresponding epitope-specific IgE and non-IgE autoantibodies for a 1-2 weeks period. Absence of the specific autoantibodies would bring to a halt the related mast cell degranulation and neuropathology.
