Fig. 4. Glial proteins are increased in human AD synapse fractions and C4 is elevated in AD CSF.

a, Scatter-plot comparison of synapse proteomes from 9 months old P301S versus WT mice (x axis) and AD versus control patients (y axis)39. Only orthologous protein pairs that were present in both datasets are shown. Of the 315 proteins that were significantly increased in P301S versus WT mice (P < 0.05, FC > 2) regardless of C1q genotype), 175 were increased in patients with AD versus controls, including the labeled proteins. Overall correlation of 0.34. NC, no change. b, Levels of total and processed C4 and Factor B and processed Bb fragment in CSF from controls and patients wth AD. Each dot represents the values from one individual. CSF samples from 15 controls and 14 patients with AD were analyzed (the same patients identified in previous works4; cohort 1). Data were analyzed by two-tailed unpaired Student’s t-test. All data are presented as mean ± s.e.m.
