Abstract
Protein glycosylation is essential to trafficking and immune functions of human neutrophils. During granulopoiesis in the bone marrow, distinct neutrophil granules are successively formed. Distinct receptors and effector proteins, many of which are glycosylated, are targeted to each type of granule according to their time of expression, a process called "targeting by timing." Therefore, these granules are time capsules reflecting different times of maturation that can be used to understand the glycosylation process during granulopoiesis. Herein, neutrophil subcellular granules were fractionated by Percoll density gradient centrifugation, and N- and O-glycans present in each compartment were analyzed by LC-MS. We found abundant paucimannosidic N-glycans and lack of O-glycans in the early-formed azurophil granules, whereas the later-formed specific and gelatinase granules and secretory vesicles contained complex N- and O-glycans with remarkably elongated N-acetyllactosamine repeats with Lewis epitopes. Immunoblotting and histochemical analysis confirmed the expression of Lewis X and sialyl-Lewis X in the intracellular granules and on the cell surface, respectively. Many glycans identified are unique to neutrophils, and their complexity increased progressively from azurophil granules to specific granules and then to gelatinase granules, suggesting temporal changes in the glycosylation machinery indicative of "glycosylation by timing" during granulopoiesis. In summary, this comprehensive neutrophil granule glycome map, the first of its kind, highlights novel granule-specific glycosylation features and is a crucial first step toward a better understanding of the mechanisms regulating protein glycosylation during neutrophil granulopoiesis and a more detailed understanding of neutrophil biology and function.

Ceciliani F, Lecchi C. The Immune Functions of α 1 Acid Glycoprotein. Curr Protein Pept Sci 2019; 20:505-524.

Abstract
α1-acid glycoprotein (orosomucoid, AGP) is an Acute Phase Protein produced by liver and peripheral tissues in response to systemic reaction to inflammation. AGP functions have been studied mostly in human, cattle and fish, although the protein has been also found in many mammalian species and birds. AGP fulfils at least two set of functions, which are apparently different from each other but in fact intimately linked. On one hand, AGP is an immunomodulatory protein. On the other hand, AGP is one of the most important binding proteins in plasma and, beside modulating pharmacokinetics and pharmacodynamics of many drugs, it is also able to bind and transport several endogen ligands related to inflammation. The focus of this review is the immunomodulatory activity of AGP. This protein regulates every single event related to inflammation, including binding of pathogens and modulating white blood cells activity throughout the entire leukocyte attacking sequence. The regulation of AGP activity is complex: the inflammation induces not only an increase in AGP serum concentration, but also a qualitative change in its carbohydrate moiety, generating a multitude of glycoforms, each of them with different, and sometimes opposite and contradictory, activities. We also present the most recent findings about the relationship between AGP and adipose tissue: AGP interacts with leptin receptor and, given its immunomodulatory function, it may be included among the potential players in the field of immunometabolism.

Abstract
Severe burns induce a complex systemic inflammatory response characterized by a typical prolonged acute phase response (APR) that starts approximately 4-8h after-burn and persists for months up to a year after the initial burn trauma. During this APR, acute phase proteins (APPs), including C-reactive protein (CRP) and complement (e.g. C3, C4 and C5) are released in the blood, resulting amongst others, in the recruitment and migration of inflammatory cells. Although the APR is necessary for proper wound healing, a prolonged APR can induce local tissue damage, hamper the healing process and cause negative systemic effects in several organs, including the heart, lungs, kidney and the central nervous system. In this review, we will discuss the role of the APR in burns with a specific focus on complement.

Abstract
One standard treatment option for advanced-stage cancer is surgical resection of malignant tumors following by adjuvant chemotherapy and chemoradiotherapy. Additionally, neoadjuvant chemotherapy may be applied if required. During the time course of treatments, patients are generally followed by computed tomography (CT) surveillance, and by tumor marker diagnosis. However, currently, early evidence of recurrence and/or metastasis of tumors with a clinically relevant biomarker remains a major therapeutic challenge. In particular, there has been no validated biomarker for predicting treatment outcomes in therapeutic settings. Recently, we have looked at glycoforms of serum α1-acid glycoprotein (AGP) by using a crossed affinoimmunoelectrophoresis with two lectins and an anti-AGP antibody. The primary glycan structures of AGP were also analyzed by a mass spectrometer and a novel software in a large number of patients with various cancers. Accordingly, the relative abundance of α1,3fucosylated glycans in AGP (FUCAGP) was found to be significantly high in cancer patients as compared with the healthy controls. Further, strikingly elevated levels of FUCAGP were found in patients with poor prognosis but not in patients with good prognosis. In the current study, levels of FUCAGP in serum samples from various cancer patients were analyzed and 17 patients including 13 who had undergone chemotherapy were followed for several years post operation. FUCAGP level determined diligently by using a mass spectrometer was found to change along with disease prognosis as well as with responses to treatments, in particular, to various chemotherapies. Therefore, FUCAGP levels measured during following-up of the patients after operation appeared to be clinically relevant biomarker of treatment intervention.

Abstract
Odontogenic tumors constitute a group of heterogeneous lesions of benign and malignant neoplasms with variable aggressiveness. Ameloblastomas are a group of benign but locally invasive neoplasms that occur in the jaws and are derived from epithelial elements of the tooth-forming apparatus. We previously described orosomucoid-1 protein expression in odontogenic myxomas. However, whether orosomucoid-1 is expressed in other odontogenic tumors remains unknown. Since orosomucoid-1 belongs to a group of acute-phase proteins and has many functions in health and disease, we identified and analyzed orosomucoid-1 expression in ameloblastoma variants and ameloblastic carcinoma using western blot and immunohistochemical techniques. Thirty cases of ameloblastoma were analyzed for orsomucoid-1; five specimens were fresh for western blot study (four benign ameloblastomas and one ameloblastic carcinoma), and 25 cases of benign ameloblastoma for immunohistochemical assays. Orosomucoid-1 was widely expressed in each tumor variant analyzed in this study, and differential orosomucoid-1 expression was observed between benign and malignant tumor. Orosomucoid-1 may play an important role in the behavior of ameloblastomas and influence the biology and development of the variants of this tumor.

Abstract
Extracellular protein misfolding is implicated in many age-related diseases including Alzheimer's disease, macular degeneration and arthritis. In this study, putative endogenous clients for the chaperone activity of α₂-macroglobulin (α₂M) were identified after human plasma was subjected to physiologically relevant sheer stress at 37 °C for 10 days. Western blot analysis showed that four major acute phase proteins: ceruloplasmin, fibrinogen, α₁-acid glycoprotein and complement component 3, preferentially co-purified with α₂M after plasma was stressed. Furthermore, the formation of complexes between α₂M and these putative chaperone clients, detected by sandwich ELISA, was shown to be enhanced in response to stress. These results support the hypothesis that α₂M plays an important role in extracellular proteostasis by sequestering misfolded proteins and targeting them for disposal, particularly during acute phase reactions.

Abstract
Human plasma α1-acid glycoprotein (AGP) from cancer patients and healthy volunteers was purified by sequential application of ion-exchange columns, and N-linked glycans enzymatically released from AGP were labeled and applied to a mass spectrometer. Additionally, a novel software system for use in combination with a mass spectrometer to determine N-linked glycans in AGP was developed. A database with 607 glycans including 453 different glycan structures that were theoretically predicted to be present in AGP was prepared for designing the software called AGPAS. This AGPAS was applied to determine relative abundance of each glycan in the AGP molecules based on mass spectra. It was found that the relative abundance of fucosylated glycans in tri- and tetra-antennary structures (FUCAGP) was significantly higher in cancer patients as compared with the healthy group (P < 0.001). Furthermore, extremely elevated levels of FUCAGP were found specifically in patients with a poor prognosis but not in patients with a good prognosis. In conclusion, the present software system allowed rapid determination of the primary structures of AGP glycans. The fucosylated glycans as novel tumor markers have clinical relevance in the diagnosis and assessment of cancer progression as well as patient prognosis.

Abstract
Variations in the amino acid sequence, glycosylation, and/or other posttranslational modifications in glycoproteins give rise to different molecules of the glycoprotein called forms. Qualitative and/or quantitative alterations in these forms are related to pathophysiological situations in the individuals. In this study, a methodology to analyze these differences in forms of the alpha 1-acid glycoprotein (AGP) between healthy individuals and patients with two different vascular diseases is detailed. The whole methodology includes a sample preparation method based on immunochromatography, a capillary electrophoresis method for separation of AGP peaks (isoforms), and statistical methods (Linear Discriminant Analysis) for sample classification. As a result, it is shown that the methodology proposed allows studying the role of AGP isoforms as potential vascular disease biomarkers.

Abstract
α-1-acid glycoprotein (AGP) is a highly heterogeneous protein that presents a vast number of isoforms (molecules of the protein differing in its peptidic and/or glycosidic moieties). In the last years, several authors have studied the potential use of AGP as a cancer biomarker. These studies focus on the correlation of different features of AGP structure (i.e. fucosylation, antennarity) with cancer or on the total protein blood concentration. In this study, the potential of CZE-UV and CZE-ESI-MS analysis of intact AGP isoforms to study the correlation of this protein with bladder cancer is shown. Samples from 16 individuals (eight healthy, eight bladder cancer) were analyzed and characterized in great detail including data on intact protein isoforms and on released glycans. The analytical data were evaluated employing different statistical techniques (ANOVA; principal component analysis, PCA; linear discriminant analysis; and partial least squares-discriminant analysis). Statistical differences between the two groups of study were observed. The best results were obtained by linear discriminant analysis of the CZE-ESI-MS data for intact AGP isoforms (93.75% of correct classification). Due to MS characterization, it can be observed that differences between the samples are mainly due to higher abundance of AGP isoforms containing tri- and tetra-antennary fucosylated oligosaccharides in cancer patients. The results show the great potential of CE-MS in combination with advanced data processing for the use of intact protein isoforms as disease biomarkers.

Abstract
This study shows the rapid and differential production of the 40-43 kDa and the 70-90 kDa alpha1-acid glycoprotein (AGP) fucosylated glycoforms after treatment of the dorsal air pouch with bacterial lipopolysaccharide (LPS), HgCl(2) or Freund's complete adjuvant (FCA). The 40-43 kDa and the 70-90 kDa AGP production is peaked 1-3 h post-LPS treatment. We observed that the responses to LPS and FCA are similar in that both AGP isoforms are induced whereas they differ in that the FCA exhibits a 6 h lag period. The response to HgCl(2,) however, exhibits the specific biphasic induction only of the 40-43 kDa AGP. The serum 40-43 kDa AGP glycoform gradually increases in response to all of the above stimulants and peaks by 24 h post- treatment. The increase of the 70-90 kDa AGP levels in the air pouch occurs in association with the accumulation of polymorphonuclear (PMN) cells while dexamethasone (DEX) increases only the 40-43 kDa AGP production in the absence of PMN accumulation. Macrophage-monocyte lineage cells forming the air pouch lining tissue may potentially be the cells that secrete the 40-43 kDa AGP while polymorphonuclear cells that infiltrate the air pouch secrete the 70-90 kDa AGP. The 40-43 kDa and 70-90 kDa AGP production induced by LPS in the air pouch precedes that of interleukin-1 (IL-1) or interleukin-6 (IL-6) while the 40-43 kDa AGP glycoform potentially increases IL-6 production by air pouch PMN exudate cells. These significant differences suggest a local pro-inflammatory role of AGP. Honeybee venom suppressed arthritis development and exhibited differential local or systemic regulation of AGP in serum vs. air pouch exudate or synovial fluid. This study with the air pouch model of facsimile synovium tissue suggests that local alpha1-acid glycoprotein (AGP) production may contribute to pro-inflammatory and anti-inflammatory activities during the local acute phase response or during chronic inflammatory stress as in arthritis.

Abstract
Alpha 1-acid glycoprotein (AGP) is a very heterogeneous glycoprotein presenting several isoforms due to variations in its polypeptidic and glycosidic moieties. Differences in AGP isoforms between healthy and diseased individuals have been related to different pathological situations such as cancer or cardiovascular diseases, among others. Capillary electrophoresis study of the role of AGP isoforms as biomarkers requires prior purification of AGP from biological samples. Current AGP purification methods are time- and labour-consuming, and generally they have not been proven to be compatible with capillary electrophoresis analysis. In this work, different methods for AGP purification from human serum are developed and compared. The applicability of acidic precipitation and immunoaffinity chromatographic methods for AGP purification are studied. Two different immunoaffinity approaches are employed; in the first one, interferents present in the AGP sample are captured and removed, and in the second one, AGP is retained in a house-made anti-AGP column, being in this way isolated from the rest of interferents of the sample. Best results in AGP purification from human serum to be analyzed by capillary zone electrophoresis (CZE) were obtained when acidic purification was combined with immunoaffinity chromatography (IAC) employing the house-made anti-AGP column. The method was shown not to alter the proportion of AGP peaks due to isoforms existing in AGP samples. The applicability of this fast and easy purification method developed for analyzing by CZE isoforms of AGP from natural serum samples by CZE is demonstrated.

The expression of fucose isoforms of amniotic and plasma alpha-1-acid glycoprotein derived from 2nd and 3rd trimester normal pregnancies. Clin Biochem 2009; 42:1517-23. [PMID: 19616527 DOI: 10.1016/j.clinbiochem.2009.06.031] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2009] [Revised: 06/26/2009] [Accepted: 06/30/2009] [Indexed: 12/29/2022]
Abstract
OBJECTIVES To analyse modifications in AGP fucosylation in relation to different stages of human pregnancy. DESIGN AND METHODS The relative amounts of three fucosyl-glycotopes on AGP were analysed by lectin-ELISA using fucose-specific biotinylated lectins in 169 plasma and 178 amniotic fluid samples from normal pregnancies with gestational ages of 14 to 42 weeks. RESULTS The plasma AGPs of all the pregnant women and amniotic AGPs from the 2nd trimester lacked fucoses. In contrast, in the 3rd trimester the amniotic AGPs were highly decorated by the innermost alpha1,6-fucose as well as alpha1,2- and alpha1,3-fucoses of the outer arms, reaching the highest expression around the perinatal period. At delivery the relative amounts of the alpha1,3- and alpha1,2-AGP isoforms, but not the alpha1,6 isoform, significantly decreased. CONCLUSIONS The highly fucosylated amniotic AGP isoforms could be implicated in regulatory processes to ensure homeostasis during pregnancy and to protect the fetus. They have the potential of becoming laboratory markers in obstetrics to monitor pregnancy.

Abstract
BACKGROUND Although highly protective, cardiac surgery using cardioplegia and cardiopulmonary bypass (CP/CPB) subjects myocardium to hypothermic reversible ischemic injury that can impair cardiac function which results in a greatly enhanced risk of mortality. Acute changes in myocardial contractile activity are likely regulated via protein modifications. We performed the following study to determine changes in the protein profile of human myocardium following CP/CPB. METHODS AND RESULTS Right atrial appendage was collected from 8 male patients pre and post-CP/CPB. Atrial tissue lysates were subjected to 2-dimensional electrophoresis, total protein staining, gel averaging, and quantitative densitometry. Ten prominent spots regulated in response to CP/CPB were identified using mass spectrometry. Two hundred twenty-five and 256 protein spots were reliably detected in 2D-gels from pre- and post-CP/CPB patients, respectively. Five unique (ie, not detected post-CP/CPB) and 17 significantly increased spots were detected pre-CP/CPB. Thirty-four unique and 25 significantly increased spots were detected in the post-CP/CPB group. Identified proteins that changed after CP/CPB included: MLC-2a, ATP-synthase delta chain and Enoyl-CoenzymeA hydratase, glutathione-s-transferase omega, alpha-1-acid-glycoprotein, and phosphatidylethanolamine-binding protein. CONCLUSIONS Cardiac surgery results in multiple consistent changes in the human myocardial protein profile. CP/CPB modifies specific cytoskeletal, metabolic, and inflammatory proteins potentially involved in deleterious effects of CP/CPB.

Abstract
Platelet (PLT)-endothelial cell and PLT-leukocyte interactions at lesion-prone sites might trigger a local inflammatory response early in the genesis of atherosclerosis and contribute to plaque destabilization leading to acute coronary syndromes (ACS). The aim of this study was to assess the PLT count, mean PLT volume (MPV), PLT mass, white blood cell (WBC; including eosinophils) and plasma interleukin (IL)-5, in patients with ACS and controls. PLT count, MPV, PLT mass, WBC and eosinophil percentage were determined in 167 consecutive patients with ACS (86 with acute myocardial infarction, AMI, and 81 unstable angina, UA) and 83 controls. Plasma IL-5 was measured in some patients and controls. Patients were considered in subgroups depending on smoking status and if they had or did not have diabetes mellitus (DM). The PLT count was lower in the UA and AMI groups although this did not always achieve significance. The MPV was significantly raised in all patient groups except in DM non-smokers with UA or AMI. All AMI patients had significantly higher WBC counts compared with controls. The percentage of eosinophils was lower in the UA and AMI groups although this did not always achieve significance. Plasma IL-5 levels were significantly increased in the UA and AMI groups. In conclusion, patients with ACS present with changes in the count of several cell types. These cells may become therapeutic targets and these changes may also act as markers of myocardial damage or prognosis.

Abstract
To analyze fucosylation of alpha(1)-acid glycoprotein (AGP) and to identify relations between AGP fucosylation and clinical and biochemical indices of disease activity in patients with rheumatoid arthritis (RA) treated with monoclonal antitumor necrosis factor (TNF) antibody infliximab, we examined 22 patients with RA who underwent a 54-week treatment with infliximab according to ATTRACT protocol. Blood samples were collected at baseline and before every infusion of infliximab. AGP fucosylation was measured using lectin-binding enzyme-linked immunosorbent assay utilizing fucose-specific lectin Aleuria aurantia (AAL). Moreover, the clinical status/activity, erythrocyte sedimentation rate, serum C-reactive protein (CRP), antitrypsin, alpha(1)-antichymotrypsin, AGP reactivity with concanavalin A, serum C3 and C4 complement components, and serum concentrations of TNF and soluble TNF type 1 and type 2 receptors were determined. In most patients, the fucosylation of AGP decreased rapidly after first infusion of infliximab and remained low during the 54-week therapy (p < 0.001). The decrease in AGP affinity to AAL closely followed changes in clinical and laboratory activity of RA and correlated with pretreatment concentrations of CRP (r = 0.4986, p < 0.05) and TNF (r = 0.5181, p < 0.05). The fucosylation of AGP can be a part of a negative feedback loop regulating migration of inflammatory cells and collagenase-3 activity in RA. The decrease in AGP fucosylation accompanied by improvement in clinical and biochemical parameters of RA could possibly reflect reduced migration of inflammatory cells to inflamed joints and AGP-mediated inhibition of collagenase-3 as a response to infliximab treatment.

Abstract
Alpha-1 acid glycoprotein (AGP, orosomucoid), a major acute phase protein in plasma, displays potent cytoprotective and anti-inflammatory activities whose molecular mechanisms are largely unknown. Because AGP binds various exogenous drugs, we have searched for endogenous ligands for AGP. We found that AGP binds lysophospholipids in a manner discernible from albumin in several ways. First, mass spectrometric analyses showed that AGP isolated from plasma and serum contained lysophosphatidylcholine (LPC) enriched in mono and polysaturated acyl chains, whereas albumin contained mostly saturated LPC. Second, AGP bound LPC in a 1:1 molar ratio and with a higher affinity than free fatty acids, whereas albumin bound LPC in a 3:1 ratio but with a lower affinity than that of free fatty acids. Consequently, free fatty acids displaced LPC more avidly from albumin than from AGP. Competitive ligand displacement indicated the highest affinity for AGP to LPC20:4, 18:3, 18:1, and 16:0 (150-180 nM), lysophosphatidylserine (Kd 190 nM), and platelet activating factor (PAF) (Kd 235 nM). The high affinity of AGP to LPC in equilibrium was verified by stopped-flow kinetics, which implicated slow dissociation after fast initial binding, being consistent with an induced-fit mechanism. AGP also bound pyrene-labeled phospholipids directly from vesicles and more efficiently than albumin. AGP prevented LPC-induced priming and PAF-induced activation of human granulocytes, thus indicating scavenging of the cellular effects of the lipid ligands. The results suggest that AGP complements albumin as a lysophospholipid scavenging protein, particularly in inflammatory conditions when the capacity of albumin to sequester LPC becomes impaired.

Abstract
Post-translational modifications (PTMs) of proteins produced in vivo may be tissue, developmentally and/or disease specific. PTMs impact on the stability and function of proteins and offer a challenge to the commercial production of protein biotherapeutics. We have previously reported a marked deficit in galactosylation of oligosaccharides released from polyclonal IgG isolated from sera of patients with the anti-neutrophil cytoplasmic antibodies (ANCA) associated vasculitides; Wegener's granulomatosis (WG) and microscopic polyangiitis (MPA). Whilst normal polyclonal IgG molecules are glycosylated within the IgG-Fc region, approximately 20% of molecules also bear oligosaccharides attached to the variable regions of the light or heavy chain IgG-Fab. It is of interest, therefore to compare profiles of oligosaccharides released from the IgG-Fc and IgG-Fab of normal IgG with that isolated from the sera of patients with WG or MPA. This study shows that whilst the oligosaccharides released from ANCA IgG-Fc are hypogalactosylated those released from IgG-Fab are galactosylated and sialylated. These results show that hypogalactosylation of IgG-Fc is not due to a defect in the glycosylation or processing machinery. It rather suggests a subtle change in IgG-Fc conformation that influences the addition of galactose. Remarkably, this influence is exerted on all plasma cells. Interestingly, a licensed monoclonal antibody therapeutic, produced in Sp2/0 cells, is also shown to be hypogalactosylated in its IgG-Fc but fully galactosylated in its IgG-Fab.
