CCR5 expression in TBEV-infected patients dependent on the clinical form of the disease. Expression of CCR5 in the activated Th lymphocyte population (CD3+CD4+CD45RO) measured cytometrically as described in “Methods” and expressed as mean fluorescence index (MFI), in peripheral blood (PB) and cerebrospinal fluid (CSF) of patients with the infection with tick-borne encephalitis virus (TBEV) presenting as meningitis (M), meningoencephalitis (ME), and meningoencephalomyelitis (MEM) as well as in peripheral blood of patients with a mild flu-like TBEV infection (F) on admission to hospital (I), 10–14 days later (II) and 4–6 weeks later (III). Shown are median (horizontal line), quadrilles (box), and minimum and maximum values (whiskers); in the least numerous groups, not allowing for statistical analysis, only individual values are shown as circles instead. There was no significant difference between the CCR5 expression in patients with different clinical presentation of TBEV infection
