Scientific Data Images for Human RGM-A Antibody

RGM-A antibody in Human Brain by Immunohistochemistry (IHC-P).

RGM‑A in Human Brain.

RGM-A was detected in immersion fixed paraffin-embedded sections of human brain (spinal cord) using Goat Anti-Human RGM-A Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2459) at 15 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to the dorsal horn.

Detection of RGM-A by Western Blot

HFE2 administration significantly improves EAE disease outcome. A Western Blot analysis shows a strong HFE2 reduction in EAE animal serum when compared to control. ELISA quantification showing HFE2 decrease and RGMa increase in EAE animal serum (mean ± s.d.; EAE n = 3 and RGMa n = 3). b Body conditioning assessment (‘0’ no paralysis to ‘4’ forelimb weakness) of EAE-induced mice with HFE2 + /- RGMa treatment every 3 days (d3, 6, 9, 12 and 15; mean ± s.e.m.; unpaired two-tail t-tests; PBS n = 8, HFE2 n = 6, RGMa+ HFE2 n = 8). c Body conditioning assessment of EAE-induced Hfe2fl/fl and Hfe2 deltaAlb-cre mice (mean ± s.e.m.; unpaired two-tail t-tests; Hfe2fl/fln = 8 and Hfe2 deltaAlb-cren = 8). d Representative confocal images of CD3 + , B220+ and CD11b+ immune staining in spinal cord of EAE-induced mice 3 weeks after induction and quantification (mean ± s.e.m.; unpaired two-tail t-test; PBS n = 7, HFE2 n = 6 mice; technical replicates shown). e Schematic of activated immune cell adoptive transfer. Representative confocal images of CD4-positive labelled transferred cell (CellVue) in PBS-treated or HFE2-treated recipient WT mice and quantification (mean ± s.e.m.; unpaired two-tail t-test; PBS n = 6, HFE2 n = 6). Ptx; Pertussis Toxin. f Representative confocal images of fibrinogen in the spinal cord of HFE2-treated EAE-mice and quantification (mean ± s.e.m.; unpaired two-tail t-test; PBS-treated n = 6 and HFE2 n = 6). *P < 0.05, **P < 0.01, ***P < 0.001.

Background: RGM-A

Human Repulsive Guidance molecule (RGM) is a 33 kDa GPI-linked member of an expanding RGM-related family of neuronal and muscle-expressed membrane proteins (1). It is synthesized as a 450 amino acid (aa) preproprotein that contains a 47 aa signal sequence, a 121 aa N-terminal prosegment, a 256 mature region and a 26 aa C-terminal prosegment (2). The N-terminal prosegment contains an RGD tripeptide and the molecule’s only two potential N-linked glycosylation sites. The mature segment shows an abbreviated von Willebrand factor domain. Proteolytic processing occurs at an aspartic acid-proline bond, creating a predicted 32 kDa mature region (2). The mature region of human RGM-A has 88% and 93% aa identity to the chick and mouse mature region of RGM-A, respectively. When compared to human RGMb and c, the mature region of human RGM-A shows 58% and 54% aa identity, respectively. Recombinant chick RGM-A has been reported to induce collapse of temporal but not nasal growth cones, and to repel temporal retinal axons in vitro. This suggests a role in the development of the retina-superior colliculus connection. In mammals, however, this activity is not so evident, and thus its function in this system is uncertain (3). Alternatively, in mice, RGM-A is said to be needed for neural tube closure, and may play a role in entorhinal-hippocampal connections (3, 4). The receptor for RGM-A is reported to be neogenin (5, 6). RGM-A has also been shown to be a bone morphogenic protein co-receptor, able to bind both BMP-2 and BMP-4 (7).
