In order to validate the results obtained on the PCR array, we used qPCR to determine the expression pattern of 5 genes in 7-week-old Npc1+/+ (white columns) and Npc1-/- (black columns) cerebral cortex. Control mice were used as reference group for the relative quantitation. Mean and standard deviation are shown for each group (N=4). An unpaired t-test with Welch’s correction, when necessary, was performed to determine the significance of the difference in means between the log10 values of control and mutant mice relative quantitation at each age. Supplemental Figure 2: Weight loss and survival of Npc1 mice with Ccl3 deficiency. Mean weight measurement for female (a) and male (b) mice of the different genotypes. Numbers of animals in each group are indicated below each graph. (c) Kaplan-Meier survival curves of mice of the different genotypes. Age at death was approximated by their age when sacrificed, corresponding to a 20% weight loss. Supplemental Figure 3: Validation of human inflammation PCR array results. We used qPCR to determine the expression pattern of 10 genes in control (open circles) and NPC1 patients (black squares) frontal cortex and cerebellum to validate the results obtained on the PCR array. Control group was used as reference for the relative quantitation. Mean and standard deviation are shown for each group (N=4 for cerebellum; N=7 for frontal cortex). An unpaired ttest with Welch’s correction, when necessary, was performed to determine the significance of the difference in means between the log10 values of control and patient relative quantitation. Supplemental Figure 4: Cerebrospinal fluid interleukins without altered expression in NPC1 patients. Log10 transformed concentrations of 6 interleukins in cerebrospinal fluid from controls (circles) and NPC1 patients (squares). Mean and standard deviation are shown for each group. An unpaired t-test with Welch’s correction when necessary was performed to determine the significance of the difference in means between controls and patients. Supplemental Figure 5: Cerebrospinal fluid inflammation molecules without altered expression in NPC1 patients. Log10 transformed concentrations of 4 molecules in cerebrospinal fluid from controls (circles) and NPC1 patients (squares). Mean and standard deviation are shown for each group. An unpaired t-test with Welch’s correction when necessary was performed to determine the significance of the difference in means between controls and patients. Supplemental Figure 6: Comparison of CSF levels of inflammation markers with respect to miglustat treatment. (a, c, e) The group of NPC1 patients was separated between patients receiving miglustat treatment (triangles) and the ones not receiving it (inverted triangles). Mean and standard deviation are shown for each group. An unpaired t-test with Welch’s correction when necessary was performed to determine the significance of the difference in means between controls and patients. (b, d, f) Percent change in each inflammatory marker CSF concentration over time after initiation of miglustat treatment for 5 patients.
