In another study, Bogovič et al. (2019) [33] showed higher serum concentrations of Th1 mediators (including CXCL9 and CXCL10) in TBE patients with post-encephalitic syndrome, suggesting that these chemokines could be important as markers of unfavorable clinical outcome. Here, CXCL9 is linked to tick-borne encephalitis.
