IL-6, BAFF, CXCL9, CXCL10, CXCL13, GM-CSF, IFN-gamma, and TNF-alpha levels were significantly elevated in CSF from neurosarcoidosis patients compared to controls (p<0.0001), along with IL-2 (p=0.0002), IL-8/CXCL8 (p=0.0008), IL-10 (p=0.0005), and IL-13 (p=0.0018). The gene discussed is CXCL8; the disease is neurosarcoidosis.
