Figure 4. Th17 frequencies in CSF lymphocytes from neurosyphilis patients.

(A) Representative dot plot of CSF IL-17-producing cells in CD3⁺CD4⁺, CD3⁺CD4⁻ and CD3⁻ lymphocytes from neurosyphilis patients. (B) Frequencies of IL-17⁺ cells in the populations of CD3⁺, CD3⁻ lymphocytes (n = 14). (C) Frequencies of IL-17⁺ cells in the populations of CD3⁺CD4⁺, CD3⁺CD4⁻ lymphocytes (n = 14). Results represent the median + individual values.
