    Abstract Background: Endometriosis is an immune-mediated inflammatory disease that causes the growth of endometrial-like tissue outside the uterus. Diagnostics of this disease are difficult, often invasive, and time-consuming, therefore non-invasive diagnostic methods and parameters are very desirable in endometriosis detection.
    Objectives: The study aimed to check whether there are any differences in the monosaccharide composition of N-glycans in serum IgG of women with advanced endometriosis and women with mild gynecological diseases.
    Materials and methods: The study material consisted of IgG samples isolated from blood sera derived from patients diagnosed with advanced endometriosis and women without endometriosis but with other gynecological diseases. To determine the monosaccharide composition of N-glycans in IgG, the gas chromatography-mass spectrometry (GC-MS) method was used.
    Results: It was observed a significantly higher content of GlcNAc in the group of women with mild gynecological diseases, compared to the group of patients with advanced endometriosis (6.5 ± 5.2 and 4.5 ± 5.7; p = 0.0007704, respectively). In addition, the content of fucose was significantly higher in the group of women with mild gynecological diseases compared to women with advanced endometriosis (1.9 ± 0.5 and 1.7 ± 1.2; p = 0.000274, respectively).
    Conclusions: The content of GlcNAc and fucose in serum IgG may be useful markers differentiating patients with advanced endometriosis from women without endometriosis but with mild gynecological diseases.

    Abstract Endometriosis is an inflammatory disease which diagnostics is difficult and often invasive, therefore non-invasive diagnostics methods and parameters are needed for endometriosis detection. The aim of our study was to analyse the glycosylation of native serum IgG and IgG isolated from sera of women classified as: with endometriosis, without endometriosis but with some benign ginecological disease, and control group of healthy women, in context of its utility for differentiation of advanced endometriosis from the group of healthy women. IgG sialylation and galactosylation/agalactosylation degree was determined using specific lectins: MAA and SNA detecting sialic acid α2,3- and α2,6-linked, respectively, RCA-I and GSL-II specific to terminal Gal and terminal GlcNAc, respectively. The results of ROC and cluster analysis showed that the serum IgG MAA-reactivity, sialylation and agalactosylation factor may be used as supplementary parameters for endometriosis diagnostics and could be taken into account as a useful clinical tool to elucidate women with high risk of endometriosis development. Additionally, we have shown that the analysis of native serum IgG glycosylation, without the prior time-consuming and expensive isolation of the protein, is sufficient to differentiation endometriosis from a group of healthy women.

    Abstract Endometriosis is a gynecological disease, the pathogenesis of which seems to be directly related to inflammatory processes with an immune basis. Our study aimed to analyze the O-glycosylation of native serum IgG and IgG isolated from sera of women with advanced endometriosis, without endometriosis but with benign gynecological diseases, and from a control group of healthy women, in the context of its utility for differentiation of advanced endometriosis from the other two groups of women studied. For the analysis of serum IgG O-glycosylation and the expression of multi-antennary N-glycans, lectin-ELISA with lectins specific to O-glycans (MPL, VVL, and Jacalin) and highly branched N-glycans (PHA-L) was used. The relative reactivities of isolated serum IgG O-linked glycans with specific lectins as well as the MPL/VVL O-glycosylation ratio were significantly higher in patients with advanced endometriosis and those with other gynecological diseases when compared to the control group of healthy women. We also showed significantly higher expression of PHA-L-reactive multi-antennary N-glycans in isolated IgG in the advanced endometriosis and the non-endometriosis groups in comparison to the control group. Additionally, significantly higher expression of Jacalin-reactive O-glycans in isolated IgG was observed in the non-endometriosis than in the advanced endometriosis group. The results of the ROC curve and cluster analysis additionally confirmed that the lectin-based analysis of isolated serum IgG O-glycosylation and the expression of highly branched N-glycans may help distinguish women with advanced endometriosis from healthy women. Moreover, the analysis of the expression of Jacalin-reactive i-IgG O-glycans may be helpful in differentiation between women with advanced endometriosis and patients with other gynecological diseases with an inflammatory background. In the case of non-endometriosis patients, the observed differences were most probably caused by increased expression of core 3 type O-glycans.

    Abstract Background: Endometriosis is an inflammatory disease leading to the growth of endometrial-like tissue outside of the uterus, which affects approximately 10% of young women of reproductive potential. The diagnosis of this disease is difficult, often invasive and time-consuming, therefore non-invasive diagnostic methods are strongly desirable in endometriosis detection. The aim of our project was to investigate whether any associations exist between the expression of serum IgG fucosylation and advanced stages of endometriosis. We were also interested in whether native serum IgG (s-IgG) fucosylation analysis, without prior IgG isolation, could provide a panel of parameters helpful in non-invasive diagnostics of advanced endometriosis.
    Methods: IgG fucosylation was examined using a lectin-ELISA test with fucose-specific lectins: AAL and LCA, specific for core fucose α1,6-linked, as well as LTA and UEA which recognize α1,3- and α1,2-linked fucose, respectively.
    Results: ROC curve and cluster analysis showed s-IgG reactivities with the panel of fucose-specific lectins AAL, LCA and LTA.
    Conclusion: s-IgG reactivity with the panel of fucose-specific lectins AAL, LCA and LTA can be taken into account as a useful diagnostic and clinical tool to differentiate women with advanced endometriosis. Moreover, it has been shown that the analysis of native IgG fucosylation directly in serum, without prior time-consuming, expensive IgG isolation, is sufficient to distinguish advanced stages of endometriosis from a control group of healthy women.

    Abstract Archivum Immunologiae et Therapiae Experimentalis (AITE) was founded in 1953 by Ludwik Hirszfeld, a world famous Polish physician and scientist in the field of microbiology and immunology. Initially, AITE was published in Polish, but within a few years, it changed to English to increase the range and number of international readers. In its over 65 year history, AITE has had several Editors and a number of Publishers. In the period 1977-1991, AITE was listed in the system of scientific information Current Contents/Life Sciences, but for several years, its impact on the international readership of the Journal was negligible. The political and economic crisis in Poland in late 1980s led to serious delays in printing of successive AITE issues, so the Journal was removed from the Current Contents. Year 1991 was a turning point for the Journal, guided since then by prof. Dubowska-Inglot, who changed its image and format, and allowed acceptance of review articles. In 1999, prof. Górski became the Editor-in-Chief, giving a new impulse for further development of the Journal. In a consequence, AITE was accepted to Science Citation Index Expanded (in 2001) and to Institute for Scientific Information Master Journal List (in 2002). Eventually, AITE has evolved to become a truly international, multidisciplinary journal, publishing original articles, and reviews relating to basic and clinical immunology, experimental therapy, immunogenetics, transplantology, microbiology, immunochemistry, as well as bioethics. Currently, AITE is cited in a number of major scientific information databases. Since 2011, the Journal is published by Springer Publishing House, it has achieved international recognition with its latest impact factor (for 2017) of 3.018. AITE, whose Editors are professors of Hirszfeld Institute of Immunology and Experimental Therapy, strengthens the status and position of the Institute as one of the leading scientific institutions in Poland.

    Abstract Spingolipids (SLs) are an important component of central nervous system (CNS) myelin sheaths and affect the viability of brain cells (oligodendrocytes, neurons and astrocytes) that is determined by signaling mediated by bioactive sphingoids (lyso-SLs). Recent studies indicate that two lipids, ceramide and sphingosine 1-phosphate (S1P), are particularly involved in many human diseases including the autoimmune inflammatory demyelination of multiple sclerosis (MS). In this review we: (1) Discuss possible sources of ceramide in CNS; (2) Summarize the features of the metabolism of S1P and its downstream signaling through G-protein-coupled receptors; (3) Link perturbations in bioactive SLs metabolism to MS neurodegeneration and (4) Compile ceramide and S1P relationships to this process. In addition, we described recent preclinical and clinical trials of therapies targeting S1P signaling, including 2-amino-2-propane-1,3-diol hydrochloride (FTY720, fingolimod) as well as proposed intervention to specify critical SL levels that tilt balances of apoptotic/active ceramide versus anti-apoptotic/inactive dihydroceramide that may offer a novel and important therapeutic approach to MS.

    Abstract Antigens belonging to the P1PK, GLOB, and FORS blood group systems and the GLOB blood group collection represent a closely related set of 13 glycosphingolipids (GSLs). They are synthesized by the coordinated action of glycosyltransferases, encoded by at least 7 different loci. Three of these enzymes show either different activity or a different mRNA expression profile due to genetic polymorphisms, resulting in blood group diversity. In recent years, significant progress has been made in understanding the molecular background and biological functions of these GSLs. Their medical significance is often related to the existence of natural antibodies, as they may cause complications after transfusions and during pregnancies. In addition, GSLs belonging to these blood group systems are receptors for several pathogens. This review summarizes the present knowledge about the complicated network of enzymatic interactions leading to synthesis of these GSLs, as well as their clinical implications.
