Firstly, it shows that the chemokines measured in the AH of patients with ocular syphilis correlate to the values previously found in the CSF of patients with neurosyphilis, and that patients with ocular syphilis have elevated CSF levels of CXCL13, CXCL10 and CXCL8, as expressed in the mean values (Figures 1–3). The gene discussed is CXCL8; the disease is neurosyphilis.
