Image caption:
Delayed recruitment of phagocytic cells and increased MHC II activation in the epineurium of DA rats.
Immunofluorescence micrographs illustrating sections of the whiskers area at 2 dpi (A, B, D, F, I and K) and 4 dpi (E, G, J and L). The DA (A, D, E, I and J) and the PVG (B, F, G, K and L) sections were stained with macrophage marker Iba1 (green, A, B, D–G and I–L), MHC II marker (red, A, B and D–G) to show the antigen presenting properties and phago-lysosome marker ED1 (red, I–L). Cellular quantification is represented in C, H and M panels. (A–C) At 2 dpi massive recruitment of Iba1+ cells (green) was present in the whiskers area of both DA (A) and PVG (B) rats at the site of the infection. However, the quantification of infiltrating Iba1+ cells to the epineurium (C) showed that the recruitment of macrophages was delayed and reduced in the epineurium of DA (arrow in A) compared to PVG rats (arrow in B). (D–H) At 2 dpi (D, F, H) the activation of antigen presenting cells detected by MHC II (red) was similar in both strains, but at 3 dpi (H) and 4 dpi (E and H) MHC II increased in DA compared to PVG rats (G and H). At 4 dpi in the whiskers area of DA rats (E) Iba1+/MHC II+ cells (arrows in E) were seen in the perineurium, in a pattern similar to the HSV-1 staining seen in Figure 1. In PVG rats (G), double and single stained Iba1+ and MHC II+ cells were more scattered in the vicinity of nerve fascicles (arrows in G), not delineating the perineurium in the same way as in DA. (I–M) Most Iba1+ cells were also ED1+ in both DA (I and J) and in PVG rats (K and L) indicating their phagocytic activity (arrows). However, there were more ED1+ cells in PVG at 2 dpi and 3 dpi compared to DA (M). At 4 dpi (J and L), Iba1+/ED1+ cells clearly delineated the perineurial cell layer in DA (arrows in J), but not in PVG (arrow in L), where these cells remained in the epineurium. Asterisks (E and G) point to the cellular infiltration into the epineurium; small arrows indicate cells in the perineurium; arrowheads indicate differences in Iba1+ morphology in DA compared to PVG rats; n, nerve fascicles; dots in panel C represent outliers. Scale bar: 50 μm.

Mouse anti Rat MHC Class II RT1B antibody, clone OX-6 (MCA46G) used to label activated microglia in mouse brain by immunohistochemistry on formalin fixed cryosections.
Image caption:
OX 6 labeled immunohistochemical images and stacked graph showing stress related changes in microglial population: From the OX 6 labeled images it is evident that both single and combined exposure of Poly I:C and LPS to HP and LP animals hyped MHC II expression in the hippocampus of the stressed animals when compared to HP control (I) and LP alone groups (M). HP+Poly I:C (J), HP+LPS (K) and HP+Poly I:C+LPS groups (L) were seen to contain intensely labeled OX 6 positive cells around the CA layer, which was comparatively less prominent in LP groups (N,O P), (n=6 slides from different animals/group, scale bar=100μm). From the quantification data (R) it was seen that, MHC II expression increased in both HP and LP animals, consequent upon Poly I:C and LPS treatment. LP groups however showed comparatively less MHC II expression when compared to similarly treated HP groups. (n=108 images, 6 slides from different animals/group), values are expressed as mean±SEM; ***P≤0.001 with respect to controls; ###P≤0.001 with respect to LP alone group; αααP≤0.001 with respect to HP+Poly I:C and LP+Poly I:C; βββP≤0.05 with respect to HP+LPS and LP+LPS; γγγP≤0.001 with respect to HP+Poly I:C+LPS and LP+Poly I:C+LPS.

Antibody Quality and 
Unrivaled 
| Mouse anti Rat MHC Class II RT1B antibody, clone OX-6 recognizes a monomorphic determinant of the rat RT1B MHC class II antigen present on B lymphocytes, dendritic cells, some macrophages and certain epithelial cells. Rat MHC Class II RT1B antibody, clone OX-6 does not react with the rat BDIX strain due to a defect in RT1B expression (Male et al. 1987). The major histocompatibility complex (MHC) is a cluster of genes that are important in the immune response to infections. In rats, this complex is referred to as the RT1 region. In mice, this complex is referred to as the H-2 region. Mouse anti Rat MHC Class II RT1B antibody, clone OX-6 also cross reacts with a polymorphic determinant on mouse strains of the H-2 haplotypes k and s. Analysis of recombinant mouse strains has mapped the OX-6 determinant to the H-2I-A region (McMaster and Williams 1979 and Male et al. 1987). Mouse anti Rat MHC Class II RT1B antibody, clone OX-6 is routinely tested in flow cytometry on rat splenocytes. |
