MPDS for all groups in the vehicle study. The highest disease score for each mouse through the entire study was determined and then averaged and the mean and SE were plotted. Statistical analysis of the MPDS data was carried out using the Mann–Whitney rank sum test to determine if the presence of TAT-Cd0 reduced MPDS scores when compared against vehicle only, controls, and untreated infected controls. (A) Treatment of mice with peptide in tears, PBS, cream, or gel. (B) Treatment of mice with vehicles only.
