Detection of Human Hemoglobin by Immunohistochemistry Neurovascular unit component expression in leaked versus non-leaked vessels along the spinal cord axis. Immunohistochemical labelling of neurovascular unit markers in ALS spinal cord (a–l); tight junctions claudin-5 (a, g) and ZO-1 (b, h), efflux pump P-glycoprotein (c, i), basement membrane marker collagen IV (d, j), and astrocyte markers aquaporin 4 (e, k) and GFAP (f, l), in spinal cord vessels with or without hemoglobin leakage. Scale bar = 50 µm. Automated quantification of average intensity staining of neurovascular unit markers was carried out in all ALS cases (n = 13) or in a subset of ALS cases with high hemoglobin leakage (n = 5) in leaked and non-leaked areas of the white and gray matter of the spinal cord (m–r). Composite of original images showing anti-hemoglobin immunoreactivity (red) and lectin-positive vessels (green) (m) and overlays of hemoglobin leakage analysis output (white, partly transparent) over anti-hemoglobin (red) (n). Segmentation of vessels inside (magenta) or outside (white) areas of hemoglobin leakage in the white matter (o) or gray matter (p). Dashed lines show boundaries. Scale bar = 1 mm. Perivascular astrocyte endfeet staining (green) around lectin-positive vessels (white) in (q) was isolated using an automated mask of the glia limitans (r). Scale bar = 50 µm. The average intensities of marker staining were measured in leaked and non-leaked vessels of the gray and white matter (s–x). Data shown as mean ± SD (n = 5 or 13) with statistical significance determined with a two-way repeated-measures ANOVA with Sidak’s post-test. ns = not significant Image collected and cropped by CiteAb from the following open publication (https://pubmed.ncbi.nlm.nih.gov/34446086), licensed under a CC-BY license.

Background: Hemoglobin
Hemoglobin is a tetrameric heme-containing protein that is responsible for the transport of oxygen by red blood cells in the circulation. For most of fetal development and adulthood, hemoglobin consists of two alpha chains and two beta chains. Hemoglobin zeta (HBZ) is an approximately 15 kDa alpha chain-like protein that is produced during the first few weeks of embryogenesis until the onset of alpha chain expression. Its expression is prolonged in a0-thalassemia which is characterized by deficient alpha chain production. The Gower-1, Portland-1, and Portland-2 forms of hemoglobin consist of two zeta chains in association with either two epsilon, gamma, or beta chains, respectively. Human Hemoglobin zeta shares 79% amino acid sequence identity with mouse and rat Hemoglobin zeta.
