Figure Lengend Snippet: Circulating plasma antibody reactivity to oral commensals identified in pancreatic tumor lesions. Plasma diluent (1/300) from patients with histology verified pancreas tissues: IPMN with low grade dysplasia (LGD-IPMN), IPMN with high grade dysplasia or with invasive cancer (HGD-IPMN + Cancer), or benign tumors/non-IPMN (Control) was tested in duplicates in ELISA plates coated with indicated antigen in (A–F) (bacteria: 5 × 10E7 CFU/ml, peptide 10 μg/mL). The total plasma IgG level is shown in (G) . Internal control Mean OD absorbance values of duplicates are shown. Statistical analysis was performed using the Kolmogorov–Smirnov test, ** p < 0.01, *** p < 0.001, and **** p < 0.0001.

Figure Lengend Snippet: Salivary IgA antibody reactivity to oral commensals quantified by ELISA using saliva diluent (1/16) from indicated patient group. Salivary IgA reactivity to F. nucleatum , the Fap2 mimotope, and S. gordonii (A,B,F) in HG-IPMN/Cancer patients is significantly increased compared to other groups. The differences in antibody levels against bacterial antigens of G. adiacens, S. anginosus , and E. coli (C,D,E) were insignificant between groups. Total plasma IgA level did not differ between the groups (G) . Statistical analysis was performed using the Kolmogorov–Smirnov test, * p < 0.05 and ** p < 0.01.

doi: 10.1016/j.imbio.2016.09.008

Figure Lengend Snippet: SpiB expression in the FAE is unaffected in the absence of c-Rel. (A) IHC analysis of SpiB expression (green) in the FAE of c-Rel −/− and wild-type (WT) control mice. Boxed areas in upper panels are shown at higher magnification in the lower panels. Broken lines indicate the FAE boundaries. Arrows, Spi-B + cell nuclei in the FAE. (B) Morphometric analysis showed that the number of SpiB + cells in the FAE of c-Rel −/− and WT were similar. (C) RT-qPCR analysis suggested there was no significant difference in the expression of Spib mRNA levels in Peyer’s patches from c-Rel −/− or WT mice. Gene expression data are normalised so that the mean level in samples from WT mice was 1.0.

Article Title: Brain-Derived Neurotrophic Factor Increases in the Uninjured Dorsal Root Ganglion Neurons in Selective Spinal Nerve Ligation Model

doi: 10.1523/jneurosci.21-13-04891.2001

Figure Lengend Snippet: Figure 4. Effects of intrathecal injection (arrow) of anti-BDNF antibody (20 mg, closed circles) or normal sheep IgG (20 mg, open circles) on paw withdrawal response to noxious heat of the rats that received L5 SPNL. Difference scores were calculated by subtracting contralateral withdrawal latencies from ipsilateral withdrawal latencies and expressed as mean 6 SEM (n 5 8 for each treatment). Thermal hyperalgesia was abolished for at least 2.5 hr by anti-BDNF antibody injection, whereas normal sheep IgG injection had no significant effect on the behavior. *p , 0.05 versus before L5 SPNL ( pre ope); #p , 0.05 versus before injection ( pre inj.) by one-way ANOVA followed by Fisher’s PLSD.

Article Snippet: After an additional 3 d, the development of neuropathic pain was confirmed, and sheep antiBDNF antibody (20 mg in 20 ml of PBS; Chemicon, Temecula, CA) or normal sheep IgG (20 mg in 20 ml of PBS; Cappel, Aurora, OH) was injected through the intrathecal cannula.

Figure Lengend Snippet: Figure 8. The effect of local application of anti-NGF antibody on thermal hyperalgesia in the L5 spinal nerve ligation (L5 SPNL) model. A small piece of gelatin sponge saturated with sheep anti-NGF antibody (100 mg, filled circles, n 5 5–9) or normal sheep IgG (100 mg, open circles, n 5 5) was placed on the surface of the L4 spinal nerve when the L5 SPNL was performed. The anti-NGF antibody prevented the development of ther- mal hyperalgesia for up to 6 d after surgery. Data are expressed as mean 6 SEM. *p , 0.05 versus before L5 SPNL ( pre) by one-way ANOVA followed by Fisher’s PLSD.

Arrows in (H) and (I) indicate colocalization of immunosignals of CDH6/DCX in EGFP-positive neurons in CP and IZ, respectively. Cell outline is highlighted using the GFP signal as a guide in the CDH6 and DCX panels (magenta lines in H and I). The second panels from the left in (H–J) show CDH6 grayscale, single-channel images. The fourth panels from the left in (H–I) show DCX grayscale, single-channel images. The fourth panel from the left in (J) shows a NES grayscale, single-channel image.
