Oral immunotherapy (OIT) can successfully desensitize allergic individuals to offending
foods such as peanut. Our recent clinical trial (NCT02103270) of peanut OIT allowed us to
monitor peanut-specific CD4+ T cells, using MHC-peptide Dextramers, over the course of
OIT. We used a single-cell targeted RNAseq assay to analyze these cells at 0, 12, 24, 52,
and 104 weeks of OIT. We found a transient increase in TGFβ-producing cells at 52 weeks in
those with successful desensitization, which lasted until 117 weeks. We also performed …
