Using differential mRNA display to uncover potential mediators associated with chronic rejection, we identified a cDNA fragment induced in Lewis to F344 rat cardiac allografts with arteriosclerosis but not Lewis syngrafts. The full-length cDNA (1.4 kb) isolated from a rat cardiac allograft cDNA library was 99% identical to galactose/N-acetylgalactosamine (Gal/GalNAc) macrophage lectin, a cell-surface receptor. This cDNA hybridized in Northern analysis with total RNA from eight cardiac allografts but not with host hearts, syngrafts, or other organs. There was a significant allograft-specific increase in transcript levels measured by reverse transcriptase PCR at days 7, 14, 28, and 75 in comparison with paired F344 host hearts (subject to same circulation but histologically normal), day-0 hearts, and syngrafts (P < 0.008, n = 4 at each time). Transcript levels in cardiac allografts were higher than those in paired host spleens (a major source of inflammatory cells) (P < 0.0001), indicating the localized nature of Gal/GalNAc lectin induction. By in situ hybridization and immunostaining, Gal/GalNAc lectin expression localized to a subset of inflammatory cells in cardiac allografts. These findings link Gal/GalNAc macrophage lectin to the chronic rejection process, as a possible mediator of macrophage infiltration.

UI MeSH Term Description Entries
D008264 Macrophages The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

D005690 Galactose An aldohexose that occurs naturally in the D-form in lactose, cerebrosides, gangliosides, and mucoproteins. Deficiency of galactosyl-1-phosphate uridyltransferase (GALACTOSE-1-PHOSPHATE URIDYL-TRANSFERASE DEFICIENCY DISEASE) causes an error in galactose metabolism called GALACTOSEMIA, resulting in elevations of galactose in the blood.
