Presence of anti-drug antibodies (ADA) does not negatively affect Treg populations or UPDRS motor scores. a Anti-sargramostim neutralizing serum antibody titers collected from peripheral blood of individual subjects. b Correlation of ADA titers with change in Treg frequency for all subjects. c Correlation of ADA titers with change in UPDRS Part III scores for all subjects. Correlations were determined using Pearson product-moment correlation coefficients, and P-values determined for correlation coefficients greater than 0.25. Best-fit lines were determined using linear regression
