Image caption:
HCT1026 inhibits MPTP-induced increased reactive Mac-1+ microglia in striatum and SNpc. Ageing (9-11 month-old) C57Bl/6 mice fed with a control (ct) or HCT1026 diets (30 mg kg-1) starting at -10 d, underwent an MPTP treatment, as described. At different time-intervals mice were anesthetized and rapidly perfused, the brains processed for immunohistochemistry. Coronal sections at the level of the striatum and SNpc were stained with Mac-1-Ab to localize microglial cells. A-B: Reactive (ameboid-like) microglial cells were counted at different time-intervals after saline and MPTP injection (n = 4/experimental group) in mice fed with a ct or HCT1026 diets, within both Str (A-G) and SNpc (H-N). Differences were analyzed by ANOVA followed by Newman-Keuls test, and considered significant when p <0.05. **p <0.05 vs saline; *° p <0.05 vs MPTP mice fed with ct diet. B-E: Representative confocal images of Mac-1 staining (green) in saline (B), 3 d after MPTP in mice fed with ct diet (C, 20× and D, 40×) or HCT1026 (F, 20× and G, 40×). Insets (100×) show microglia morphologic appearance. I-N: Representative confocal images of Mac-1 staining (red) in SNpc. Note the high density of reactive Mac-1+ cells with rounded cell bodies and short, thick processes 3 d after MPTP administration in mice fed with a ct diet (J-K), as compared to Mac-1 microglia of mice fed with HCT1026 (M-N), exhibiting a more elongated cell body and long ramified processes.

A-B: Western blotting of phagocyte oxidase PHOX (A) and Mac-1 (B) within the VM at different time-intervals after saline or MPTP injection in mice fed with the control or HCT1026 diet. The data from experimental bands were normalized to β-actin, before statistical analysis of variance. Values are expressed as % of saline-injected controls. Differences were analyzed by ANOVA followed by Newman-Keuls test, and considered significant when p <0.05. * p <0.05 compared to saline; ° p <0.05 vs MPTP fed with the control diet. C. Semi-quantitative RT-PCR for iNOS. The 250 ng of cDNA were used for PCR, by using Super Taq DNA polymerase with specific primer pairs for iNOS (500 bp) and Classic GADPH Standard (270 bp). Samples from PCR reactions were processed as described. Fluorescent bands of amplified gene products were analyzed, the values normalized against GADPH and ratios expressed as % of control, within each experimental group (C), see text for details. Differences were analyzed by ANOVA as above. ** p <0.05 vs saline; ° p <0.05 vs MPTP + control diet. D: Mean numbers of Mac1+iNOS+ cells within the SNpc in saline and MPTP mice fed with the control or HCT1026 diet. Cell counts obtained as described in Material section. E-F: Representative confocal images showing double staining with Mac-1 (green) and iNOS (red) in MPTP mice fed with the control (E) or HCT1026 (F) diets. G: Percent (%) of TH+ neurons colocalizing with 3-nitrotyrosine (3-NT), a peroxynitrite footprint. Dual stained TH+ 3-NT+ neurons were counted as described and values expressed as % of total TH+ neurons. H-I: Representative confocal images showing dual immunostaining with 3-NT (green) and TH (red) in MPTP mice fed with a ct diet (H) showing that a large proportion of DAergic neurons colocalize (orange-to-yellow) as opposed to TH neurons of mice fed with HCT1026 (E) where no colocalization was observed in the large part of SNpc neurons.

Rat anti mouse CD11b antibody, clone M1/70.15 (MCA74G) used for the assessment of CD11b expression by activated N9 microglial cells using immunofluorescence.
Image caption:
Localization of CD11b and p-STAT3 immunoreactivity in activated N9 cells. Experiments were performed as described above. Confocal immunofluorescence microscopy was performed on cultures that were immunoreacted with antibodies against phospho-STAT3 tyr705 (left, rabbit monoclonal, 1:100; FITC-conjugated sheep anti- rabbit secondary, 1:200) and CD11b (right, as Figure 1 shows) at 12 h after EMF exposure (A-L). (A-C) Untreated cultures were used as a control. (D-F) Cultures pretreated with P6 (10 μM). (G-I) EMF induced more phosphorylation of STAT3 (green) and expression of CD11b (red) in N9 cells. (J-L) P6 inhibits the phosphorylation of STAT3 and expression of CD11b at 12 h after EMF exposure. (M-O) P6 pretreatment significantly suppresses the phosphorylation of STAT3, but a slight and significant increase of CD11b is still apparent at 3 h after EMF exposure. Scale bar 10 μm. (P) Bar graphs show semi-quantification of fluorescence intensity for p-STAT3 and CD11b in N9 cells. Results are presented as mean ± S.D. of three independent experiments. Statistical comparisons to control are indicated by * p <0.05; ** p <0.01.

Antibody Quality and Performance Guarantee
| Rat anti Mouse CD11b antibody, clone M1/70.15 recognizes the murine CD11b cell surface antigen also known as the alpha M integrin chain or MAC-1, a differentiation antigen expressed by granulocytes, monocytes, NK cells and tissue macrophages. The expression of CD11b increases during monocyte maturation and expression levels vary on tissue macrophages. Peritoneal macrophages are reported to express higher levels of CD11b than splenic macrophages. Rat anti Mouse CD11b antibody, clone M1/70.15 has been reported to block iC3b binding to its receptor (Beller et al. 1982). Rat anti Mouse CD11b antibody, clone M1/70.15 has been reported to as being suitable for use on PLP fixed paraffin embedded tissue but has not been tested for use on formalin fixed tissue (Whiteland et al. 1995). This product is routinely tested in flow cytometry on mouse peritoneal macrophages. |
