[PMID: 38556552 PMCID: PMC11058272 DOI: 10.1038/s12276-024-01188-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2023] [Revised: 12/04/2023] [Accepted: 12/20/2023] [Indexed: 04/02/2024] Open
Abstract
Acute phase proteins involved in chronic inflammatory diseases have not been systematically analyzed. Here, global proteome profiling of serum and urine revealed that orosomucoid-2 (ORM2), an acute phase reactant, was differentially expressed in rheumatoid arthritis (RA) patients and showed the highest fold change. Therefore, we questioned the extent to which ORM2, which is produced mainly in the liver, actively participates in rheumatoid inflammation. Surprisingly, ORM2 expression was upregulated in the synovial fluids and synovial membranes of RA patients. The major cell types producing ORM2 were synovial macrophages and fibroblast-like synoviocytes (FLSs) from RA patients. Recombinant ORM2 robustly increased IL-6, TNF-α, CXCL8 (IL-8), and CCL2 production by RA macrophages and FLSs via the NF-κB and p38 MAPK pathways. Interestingly, glycophorin C, a membrane protein for determining erythrocyte shape, was the receptor for ORM2. Intra-articular injection of ORM2 increased the severity of arthritis in mice and accelerated the infiltration of macrophages into the affected joints. Moreover, circulating ORM2 levels correlated with RA activity and radiographic progression. In conclusion, the acute phase protein ORM2 can directly increase the production of proinflammatory mediators and promote chronic arthritis in mice, suggesting that ORM2 could be a new therapeutic target for RA.

Abstract
Antigens of the Gerbich blood group system are expressed on glycophorin C (GPC) and glycophorin D (GPD), minor sialoglycoproteins of human erythrocytes. GPC and GPD help maintain erythrocyte shape of and contributes to the stability of its membrane. There are six high-prevalence Gerbich antigens: Ge2, Ge3, Ge4, GEPL (GE10), GEAT (GE11), GETI (GE12) and five low-prevalence Gerbich antigens: Wb (GE5), Lsa (GE6), Ana (GE7), Dha (GE8), GEIS (GE9). Some Gerbich antigens (Ge4, Wb, Dha, GEAT) are expressed only on GPC, two (Ge2, Ana) are expressed only on GPD, while others (Ge3, Lsa, GEIS, GEPL, GETI) are expressed on both GPC and GPD. Antibodies recognizing GPC/GPD may arise naturally (so-called "naturally-occurring RBC antibodies") or as the result of alloimmunization, and some of them may be clinically relevant. Gerbich antibodies usually do not cause serious hemolytic transfusion reactions (HTR); autoantibodies of anti-Ge2- or anti-Ge3 specificity can cause autoimmune hemolytic anemia (AIHA).

Abstract
GYPC encodes two erythrocyte surface sialoglycoproteins in humans, glycophorin C and glycophorin D (GPC and GPD), via initiation of translation at two start codons on a single transcript. The malaria-causing parasite Plasmodium falciparum uses GPC as a means of invasion into the human red blood cell. Here, we examine the molecular evolution of GYPC among the Hominoidea (Greater and Lesser Apes) and also the pattern of polymorphism at the locus in a global human sample. We find an excess of nonsynonymous divergence among species that appears to be caused solely by accelerated evolution of GYPC in the human lineage. Moreover, we find that the ability of GYPC to encode both GPC and GPD is a uniquely human trait, caused by the evolution of the GPC start codon in the human lineage. The pattern of polymorphism among humans is consistent with a hitchhiking event at the locus, suggesting that positive natural selection affected GYPC in the relatively recent past. Because GPC is exploited by P. falciparum for invasion of the red blood cell, we hypothesize that selection for evasion of P. falciparum has caused accelerated evolution of GYPC in humans (relative to other primates) and that this positive selection has continued to act in the recent evolution of our species. These data suggest that malaria has played a powerful role in shaping molecules on the surface of the human red blood cell. In addition, our examination of GYPC reveals a novel mechanism of protein evolution: co-option of untranslated region (UTR) sequence following the formation of a new start codon. In the case of human GYPC, the ancestral protein (GPD) continues to be produced through leaky translation. Because leaky translation is a widespread phenomenon among genes and organisms, we suggest that co-option of UTR sequence may be an important source of protein innovation.

Abstract
Glycophorin-C (GPC) is a 40 kDa glycoprotein expressed on erythrocytes and is a receptor for the malarial parasite Plasmodium falciparum to invade these cells. A link between GPC binding (ligation) and phosphatidylserine (PS) expression on erythrocytes has been suggested by its appearance on P. falciparum-infected erythrocytes. Phosphatidylserine expression has also been shown to be a marker of cellular death in a number of biological pathways including some in erythrocytes. Using Annexin V binding, we demonstrated that ligation of GPC with mouse mAb (BRIC-10) induced PS expression on normal erythrocytes. Phosphatidylserine exposure was prevented following tryptic digestion of intact erythrocytes. In addition, GPC variant phenotypes Yus (Delta exon 2) and Gerbich (Delta exon 3), which express a truncated extracellular domain, did not express PS following BRIC-10 binding, whereas PS was exposed on Ls(a) erythrocytes (duplication of exon 3). GPC ligation was also shown to result in a concomitant loss of erythrocyte viability in wild-type erythrocytes after 24 h in vitro. These results identify a potential pathway linking GPC to PS exposure on erythrocytes that may have a role in regulating red cell turnover. Further characterization of this pathway may also identify new targets for the treatment of P. falciparum malaria.

Abstract
Glycophorin C (GPC) and glycophorin D (GPD) are minor but important components of human RBC membranes. They carry the high-frequency antigens Ge2, Ge3 and Ge4 of the Gerbich blood group system. The epitopes for five new monoclonal antibodies (MoAbs) with anti-GPC specificity were characterized. Two antibodies (4G11 and 5B11) reacted with glycosylated N-terminal epitopes, and three reacted with internal epitopes of GPC. Pepscan analysis showed that the MoAb RB11 required for binding the EPDP sequence, occurring twice in GPC polypeptide chain. The MoAb 7F11 recognized the sequence 13PLSLEPDP20, and the MoAb RB8 did not react with synthetic peptides. Further characterization of the internal epitopes was performed in fluorescence-activated cell sorter (FACS) with the use of recombinant GPC and its variant forms transiently expressed on COS-7 cells. The results indicated that the MoAb RB11 recognized distinctly its target sequence EPDP only in a normal GPC molecule. The reactivity of the MoAb 7F11 with the PLSLEPDP sequence was confirmed and found to be enhanced by the O-glycan at the Ser15 residue. The MoAb RB8 recognized the glycopeptidic epitope in proximity to the Ser15 residue, requiring the presence of O-glycan. The combination of immunochemical techniques with the use of the recombinant forms of GPC has made it possible to define the role of sugar chains in the recognition of peptidic epitopes in glycosylated antigen and sheds new light on the Gerbich system antigens.

Abstract
Glycophorins are complex heavily glycosylated antigens carrying peptidic and glycopeptidic epitopes. Detailed immunochemical studies showed that GPA/GPB and GPC/GPD molecules have defined sites which are particularly immunogenic. These sites include N-terminal portions of all glycophorins, internal fragments of their extracellular domains, and cytoplasmic tails. The extracellular epitopes involve directly oligosaccharide chains (e.g. blood group M- and N-related epitopes, or N-terminal epitopes of GPC) or have peptidic character, shown by the reaction of respective antibodies with synthetic peptides. Peptidic eitopes are independent of glycosylation, or are variably affected by adjacent O-glycans which may mask the epitopes or may be required for a proper exposure of an antibody binding site. Several low incidence epitopes are present on variant glycophorin molecules. Among anti-glycophorin antibodies there are the 'bispecific' ones, or antibodies recognizing an epitope formed by an interaction of two proteins (Wr(b)). Alltogether, the glycophorins serve as convenient model antigens for studying Ag-Ab interaction and a role of O-glycosylation in protein antigenic properties. Moreover, well defined specificty of monoclonal anti-glycophorin antibodies makes them more precise tools in serological investigation and identification of normal and variant antigens. Last but not least, elucidation of antigenic properties of glycophorins is important for identification and characterization of human anti-glycophorin antibodies, which in some cases create medical problems at transfusion or pregnancy.

Abstract
Monoclonal antibodies (Mabs) to blood group antigens are valuable as diagnostic reagents for typing red blood cells (RBCs) in the clinical setting, and for structure-function studies of proteins. Here, we report a powerful system that enabled us to produce Mabs to blood group antigens. A murine erythroleukaemia (MEL) cell line expressing Kell protein, a transmembrane glycoprotein that carries a number of clinically relevant antigens, was used as a novel immunogen. Mabs with different specificities to the Kell protein were produced from a single mouse fusion: an anti-Jsb (MIMA-8), and two antibodies (MIMA-9 and MIMA-10) with novel specificities, that reacted with RBCs with the common Kell phenotype but not with RBCs with K+k- or Kp(a+b-) or K0 phenotypes. The non-reactivity with both K+k- or Kp(a+b-) RBCs implied that the epitope was influenced by the molecular changes associated with an absence of the k or Kpb antigens. MIMA-8 is the first example of a Mab anti-Jsb and was used in the clinical laboratory for screening donor RBCs for Js(b-) blood and for typing RBCs from patients even when the RBCs were coated with anti-IgG as is the case in autoimmune haemolytic anaemia. Heavy and light chain variable regions of MIMA-8 were cloned and the sequence is given. This study illustrates the potential of this novel immunization approach for making monoclonal antibodies to blood group antigens.

Abstract
The PDZ domain, also known as the GLGF repeat/DHR domain, is an approximately 90-amino acid motif discovered in a recently identified family of proteins termed MAGUKs (membrane-associated guanylate kinase homologues). Sequence comparison analysis has since identified PDZ domains in over 50 proteins. Like SH2 and SH3 domains, the PDZ domains mediate specific protein-protein interactions, whose specificities appear to be dictated by the primary structure of the PDZ domain as well as its binding target. Using recombinant fusion proteins and a blot overlay assay, we show that a single copy of the PDZ domain in human erythrocyte p55 binds to the carboxyl terminus of the cytoplasmic domain of human erythroid glycophorin C. Deletion mutagenesis of 21 amino acids at the amino terminus of the p55 PDZ domain completely abrogates its binding activity for glycophorin C. Using an alanine scan and surface plasmon resonance technique, we identify residues in the cytoplasmic domain of glycophorin C that are critical for its interaction with the PDZ domain. The recognition specificity of the p55 PDZ domain appears to be unique, since the three PDZ domains of hDlg (human lymphocyte homologue of the Drosophila discs large tumor suppressor) do not bind the cytoplasmic domain of glycophorin C. Taken together with our previous studies, these results complete the identification of interacting domains in the ternary complex between p55, glycophorin C, and protein 4.1. Implications of these findings are discussed in terms of binding specificity and the regulation of cytoskeleton-membrane interactions.
