T. brucei presence is sufficient to shorten the period. a Period plot of various tissues harvested from healthy PER2::LUC mice and cultured with medium only (black) or 10⁵ T. brucei (orange). Shown are mean period ± s.d.; *adjusted p < 0.05 FDR method Benjamini–Hochberg. b Representative records of bioluminescence reporting of circadian expression from PER2::LUC ear fibroblasts co-cultured with 10⁵ T. brucei (T.b., orange). c Period comparison from PER2::LUC ear fibroblast with medium (black, n = 16) and co-cultured 10⁵ T. brucei (orange, n = 14). Unpaired t-test, * p < 0.05, from four independent experiments
