Distinct Cerebrospinal Fluid Proteomes Differentiate Post-Treatment Lyme Disease from Chronic Fatigue Syndrome

Figure 1

Characterization of the proteome from pooled and individual CSF samples.

A) Venn diagram of the qualitative distribution of proteins identified in the pooled, immunodepleted, and fractionated cerebrospinal fluid (CSF) from normal healthy control subjects, Chronic Fatigue Syndrome (CFS), and Neurologic Post Treatment Lyme Syndrome (nPTLS). The numbers of proteins for each of these three categories separately is shown outside the circles below the category (2,630 for true normal controls, 2,783 for CFS, and 2,768 for nPTLS). The subsets of intersections between these categories are shown within the circles. There were 1) 738 proteins that were identified in CFS, but not in either healthy normal controls or nPTLS; 2) 1,582 proteins that were not identified in CFS, but were in either nPTLS disease or healthy normal controls; 3) 692 proteins that were identified in the nPTLS patients, but not in healthy normal controls or CFS; and 4) 1,597 proteins that were not identified in nPTLS, but were identified in either healthy normal controls or CFS. This figure also shows that the nPTLS and CFS groups shared significantly more proteins (n = 305) than each disease group shared with controls (n's = 135 and 166). The specific lists of these subsets are presented in additional Table S1.
