A-D) Quantification of the NIRF signal intensity from the ROI in CFA-injected footpads that received CUR-NE, DF-NE, and CUR FD followed by DF-NE at t = 0 h and t = 24 h to track infiltrating macrophages. The fluorescent intensities were quantified for 7 days (t = 0 h to t = 168 h) in both male and female rats. Data represents the average±SD, n = 3/treatment group. Two-way, repeat measures ANOVA, Holm-Šídák’s multiple comparisons test, ns not significant, *p < 0.05
