Abstract
We investigated the polarisation of CD68+ macrophages and perforin and granulysin distributions in kidney lymphocyte subsets of children with IgA vasculitis nephritis (IgAVN). Pro-inflammatory macrophage (M)1 (CD68/iNOS) or regulatory M2 (CD68/arginase-1) polarisation; spatial arrangement of macrophages and lymphocytes; and perforin and granulysin distribution in CD3+ and CD56+ cells were visulaised using double-labelled immunofluorescence. In contrast to the tubules, iNOS+ cells were more abundant than the arginase-1+ cells in the glomeruli. CD68+ macrophage numbers fluctuated in the glomeruli and were mostly labelled with iNOS. CD68+/arginase-1+ cells are abundant in the tubules. CD56+ cells, enclosed by CD68+ cells, were more abundant in the glomeruli than in the tubuli, and co-expressed NKp44. The glomerular and interstitial/intratubular CD56+ cells express perforin and granulysin, respectively. The CD3+ cells did not express perforin, while a minority expressed granulysin. Innate immunity, represented by M1 macrophages and CD56+ cells rich in perforin and granulysin, plays a pivotal role in the acute phase of IgAVN.

Abstract
BackgroundActivated monocytes represent the main source of pro-inflammatory chemokine, Monocyte Chemoattractant Protein-1 (MCP-1) in psoriatic skin lesions and synovial tissue during active psoriatic arthritis (PsA) (1). Osteoclast precursors binds MCP-1, implying the involvement of MCP-1 in the pathogenesis of bone erosion (2). MCP-1 is present in the plasma of patients with psoriasis at higher levels than in healthy subjects (3).ObjectivesThe aim of this study was to determine the relationship between serum MCP-1 concentration and disease activity in PsA patients.MethodsWe enrolled 52 patients with PsA in the study and assessed Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Disease Activity in Psoriatic Arthritis (DAPSA), Bath Ankylosing Spondylitis Disease Functional index (BASFI), and the spread of psoriasis using Body Surface Area (BSA) method. In the serum, C-reactive protein (CRP) was measured using immunoturbidimetric assay and MCP-1 concentration using ELISA. Relationship between two parameters was analyzed applying Spearman correlation and p<0.05 was considered significant.ResultsSerum MCP-1 concentration did not correlate with the BSA, the DAPSA, CRP, the number of tender joints from 68 evaluated, the number of swollen joints from 66 evaluated, the patient’s assessment of the intensity of pain and overall disease activity during the last week. The concentration of MCP-1 did not correlate with the fatigue, the intensity of pain in axial and peripheral joint structures, the sensitivity to touch, the duration of morning stiffness, BASDAI and BASFI.MCP-1 statistically significantly correlated with the score for getting up from a sitting position without the help of hands, for getting up from a floor without the help, for standing up without supporting for 10 minutes and for performing physically demanding activities (Figure 1).Figure 1.Correlation of serum MCP-1 concentration and BASFI components in patients with PsA.ConclusionSerum MCP-1 concentrations in PsA patients seem to reflect some components of patient functional status.References[1]Furst DE, Louie JS.

Abstract
BackgroundOxidized low-density lipoprotein (oxLDL) particles support low-grade inflammation and have been found in synovial fluid from osteoarthritis (OA) joints [1]. Their component is 7-ketocholesterol (7-KC), which arises as the result of the oxidation of cholesterol [1]. 7-KC acts proinflammatory and it binds to Toll-like receptor (TLR) 4 expressed on macrophages [1]. Activation of TLR4 stimulates the classical macrophage maturation program, resulting in a specific phenotype of inducible nitric oxide synthase positive (iNOS+) and macrophage (M) 1 function, which produce and secrete proinflammatory chemokines and cytokines [2]. M2 macrophages are associated with wound healing by the production of arginase-1 [2,3]. Synovial macrophages are of critical importance in the symptomatology and structural progression of OA since M1 polarized macrophages accumulate in human OA synovial tissue during exacerbation [3]. However, it is not known whether 7-KC can re-program synovial tissue macrophages and support M1 polarization.ObjectivesWe analyzed the influence of 7-KC on the polarization of CD68+ macrophages in the suspension of synovial mononuclear cells (SMCs) in respect to lipopolysaccharide (LPS), as M1 inducer.MethodsMature synovial tissue samples were obtained during alloarthroplasty of the knee (N = 56). Paraffin embedded tissue sections were labelled by double immunofluorescence using a combination of antibodies directed toward CD68 and iNOS, arginase-1, CCL2 or CCL22. Suspension of SMCs was prepared by enzymatic digestion of tissue samples using collagenase IV and gradient density centrifugation. We analyzed intracellular (iNOS, arginase-1, CCL2, and CCL22) and surface (CD91, mannose receptor, HLA-DR, CD80, CD86 and decoy D6) antigens expression in CD68+ cells in the suspension of freshly isolated or 18 hour-cultured SMCs with 7-KC (25 μM), LPS (10 ng/ml), their combination or in the medium only.ResultsiNOS and CCL2 were more frequently labelled in lymphocyte clusters, while arginase-1 and CCL22 were labelled in synovial lining CD68+ cells. Phenotype of CD68+ cells did not change significantly after the 18 hour- culture in the medium only, except the decrease of mannose receptor and CD91, when compared with freshly isolated cells. 7-KC increased the percentage of CD86 expressing CD68+ cells, whereas decreased surface expression of CD91 and chemokine decoy D6, like in the culture with LPS, when compared with cells cultured in the medium only. 7-KC decreased the frequency of arginase-1+/CD68+ cells in the suspension and did not change iNOS+ in CD68+ cells, thus increasing the ratio of iNOS+/arginase-1+ in CD68+ subset. 7-KC was unable to increase CCL2 like LPS in comparison with cells cultured in the medium only. Neither 7-KC nor LPS affected CCL22 expression in the CD68+ subset.ConclusionThese data provide a new perspective in understanding the polarization of macrophages toward the M1 phenotype mediated with oxysterol 7-KC in vitro.References[1]Niki E.

Abstract
Osteoarthritis (OA) is a chronic joint disease caused by mechanical damage and metabolic factors that support the development of low-grade inflammation. Increased levels of T helper 1 pro-inflammatory cytokines in the serum of OA patients may support granulysin (GNLY) mediated cytotoxicity, which in-turn may contribute to the pathogenesis of OA. In the present study, GNLY expression and cytotoxic/apoptotic mechanisms mediated by GNLY in the peripheral blood of OA patients were assessed. A total of 40 non-obese women (median age of 64 years old) with knee OA, and 40 controls (median age 62 years old) were enrolled in the study. GNLY, IFN-γ and IL-4 expression levels were investigated in peripheral blood lymphocytes (PBLs) using flow cytometry, immunocytochemistry and/or confocal microscopy. Natural killer (NK) GNLY-mediated apoptosis through NK effectors against K-562 targets was analyzed using the PKH-26 18-h cytotoxicity assay. Serum GNLY levels were assessed using ELISA. The percentage of GNLY+PBLs was higher in the OA patients than that in the controls due to the increase in the proportions of GNLY+ cells in the natural killer (NK), T and natural killer T (NKT) subsets. GNLY localization inside exocytotic lysosomal-associated membrane protein-1+ granules was ~40% in both groups. However, the intensity of GNLY labeling in PBLs was higher in OA patients than in the controls, and it was supported by the increased expression of IFN-γ relative to IL-4 in NK and T cells from OA patients. The serum GNLY concentration was <0.3 ng/ml in both groups. RC8 anti-GNLY mAb by itself was unable to significantly alter early apoptosis, whereas RC8 anti-GNLY mAb combined with anti-perforin mAb significantly reduced NK-mediated early apoptosis of K-562 targets in the OA patients, whilst not exerting a notable effect in the controls. Anti-perforin mAb by itself did not affect apoptosis significantly. These results suggest that in women with knee OA, GNLY expression in the PBL subsets and GNLY-mediated early apoptosis of K-562 targets are increased compared with the controls and accompanied by intracellular dominance of IFN-γ over IL-4 in NK cells.

Abstract
Background: We analysed clinical and biochemical parameters in predicting severe gastrointestinal (GI) manifestations in childhood IgA vasculitis (IgAV) and the risk of developing renal complications. Methods: A national multicentric retrospective study included children with IgAV reviewed in five Croatian University Centres for paediatric rheumatology in the period 2009–2019. Results: Out of 611 children, 281 (45.99%) had at least one GI manifestation, while 42 of 281 (14.95%) had the most severe GI manifestations. Using logistic regression several clinical risk factors for the severe GI manifestations were identified: generalized rash [odds ratio (OR) 2.09 (95% confidence interval (CI) 1.09–4.01)], rash extended on upper extremities (OR 2.77 (95% CI 1.43–5.34)] or face [OR 3.69 (95% CI 1.42–9.43)] and nephritis (IgAVN) [OR 4.35 (95% CI 2.23–8.50)], as well as lower values of prothrombin time (OR 0.05 (95% CI 0.01–0.62)], fibrinogen [OR 0.45 (95% CI 0.29–0.70)] and IgM [OR 0.10 (95% I 0.03–0.35)]] among the laboratory parameters. Patients with severe GI involvement more frequently had relapse of the disease [OR 2.14 (CI 1.04–4.39)] and recurrent rash [OR 2.61 (CI 1.27–5.38)]. Multivariate logistic regression found that the combination of age, GI symptoms at the beginning of IgAV and severity of GI symptoms were statistically significant predictors of IgAVN. Patients in whom IgAV has started with GI symptoms [OR 6.60 (95% CI 1.67–26.06)], older children [OR 1.22 (95% CI 1.02–1.46)] with severe GI form of IgAV (OR 5.90 (95% CI 1.12–31.15)] were particularly high-risk for developing IgAVN. Conclusion: We detected a group of older children with the onset of GI symptoms before other IgAV symptoms and severe GI form of the IgAV, with significantly higher risk for acute and chronic complications of IgAV.

Abstract
BACKGROUND/OBJECTIVE The purpose of this study was to evaluate the prevalence and severity of skin involvement in children with IgA vasculitis (IgAV) and its relationship with clinical and biochemical parameters and the risk of developing IgA vasculitis nephritis (IgAVN), the only cause of long-term morbidity and the main prognostic factor in IgAV patients. METHODS This national multicenter retrospective study included 611 patients under the age of 18 years with IgAV referred to five Croatian tertiary hospitals between 2009 and 2019. Patient data were collected from a database with systematic analysis of IgAV patients in the Croatian population. RESULTS Among the 611 children, 205 (33.55%) had purpura on the lower extremities, in 207 (33.88%) the rash extended on the trunk, in 149 (24.39%) it extended to the upper extremities, in 32 (5.24%) the rash was generalized, while 15 (2.47%) had the most severe skin symptoms: bullae, ulcerations, and necroses. IgAVN developed in 130 (21.28%) and persistent IgAVN (present for >3 months) in 48 (7.86%) children. Multivariate logistic regression found that presence of ulcerations and necroses (OR 3.20 [95% CI 1.03-9.91]), persistent purpura (OR 2.89 [95% CI 1.71-4.88]), and higher age (OR 1.16 [95% CI 1.09-1.23]) were significant predictors of IgAVN, whereas persistent purpura (OR 20.11 [95% CI 1.09-372.52]), male sex (OR 3.32 [95% CI 1.13-9.80]), and higher age (OR 1.15 [95% CI 1.00-1.30]) were predictors of persistent IgAVN. Among the laboratory parameters, higher serum urea (OR 1.43 [95% CI 1.03-2.00]) and reduction in activated partial thromboplastin time (OR 0.83 [95% CI 0.74-0.93]) were shown to have a significant impact on increasing the risk of persistent IgAVN. CONCLUSION With increasing severity and duration of cutaneous manifestations in IgAV, the risk of developing IgAVN increases, making the prognosis worse, with a greater likelihood to need more aggressive treatment.

Abstract
Background:Macrophages are abundant inflammatory cell type in the synovial membrane of knee osteoarthritis (OA) (1). Their quantity is associated with radiographic severity of knee OA and joint symptoms (2), while their functions are set in response to micro-environmental signals (3). Classically activated macrophages M1 support T helper 1 (Th1) driven pro-inflammatory reactions, while alternatively activated macrophages M2 strengthen Th2 inflammatory processes (3).Objectives:To investigate activation status of synovial tissue macrophages in patients with mature OA in terms of M1 / M2 polarization.Methods:Synovial tissue samples (6) with abundant lymphocyte infiltration were obtained during aloarthroplasty. Double immunofluorescence labeling was performed on paraffin-embedded synovial tissue sections using primary rabbit anti-macrophage CD68 mAb in combination with mouse anti-human antibodies directed toward CD3, arginase-1, TNF-alpha and IL-15. CD206 and CD163 were single labelled.Results:CD68+ macrophages mostly co-expressed arginase-1 (4/6 samples), indicating their M2 orientation. Macrophages were placed in lining synovial tissue and nearby tissue-resident CD3+ cells. M2 markers CD206 and CD163 were found in the area of macrophage interaction with T cells. CD68+ cells co-expressing TNF-alpha or IL-15 M1 markers were in minority in these synovial tissues. Lymphocyte infiltration was less abundant in remaining (2/6) synovial tissue samples.Conclusion:Mature synovial tissue macrophages, equipped dominantly with arginase-1 are M2 oriented and might support Th2 immune response in surrounding T cells.References:[1]Grieshaber-Bouyer R, Kämmerer T, Rosshirt N, Nees TA, Koniezke P, Tripel E, Schiltenwolf M, Kirsch J, Hagmann S, Moradi B.

Abstract
BACKGROUND Coronary artery bypass grafting (CABG) surgery continues to be the gold standard for treating the patients with coronary artery disease. CABG surgery can be performed on or off cardiopulmonary bypass, termed as on-pump or off-pump CABG, respectively. It has been shown that CABG surgery, preferably on-pump CABG surgery, leads to the changes of cell immunity during perioperative and early postoperative period. The mechanisms of regulation of the immune response in patients during and early after surgical revascularization are not fully understood. The aim of this study was to investigate the influence of carbohydrate preoperative oral feeding on frequency and perforin expression in peripheral blood lymphocytes in patients after on- or off-pump CABG surgery in early postoperative period. PATIENTS AND METHODS In this prospective clinical study, 80 patients scheduled for CABG surgery were included in the study. The patients were randomly allocated into four groups (20 in each group): patients in Group 1 underwent on-pump CABG and did not receive carbohydrate preoperative oral feeding; patients in Group 2 underwent on-pump CABG and were preoperatively fed; patients in Group 3 underwent off-pump CABG and did not receive carbohydrate preoperative oral feeding; while patients in Group 4 underwent off-pump CABG and received carbohydrate preoperative oral feeding. Blood samples were collected immediately before (T1), 24 (T2) and 72 (T3) hours after the surgery. Peripheral blood mononuclear cells were isolated by gradient centrifugation and simultaneously labelled by antigens using fluorochrome-conjugated monoclonal antibodies. Frequency of T lymphocytes, NK and NKT cells, their subsets as well as their perforin expression were detected, and analyzed by flow cytometry. RESULTS There was significant decrease in frequency of CD3+ and CD3+CD4+ cells, as well as perforin expressing CD3+CD8+ cells in patients who underwent on-pump CABG in comparison to patients who underwent off-pump CABG 24 hours after the surgery. Carbohydrate preoperative oral feeding did not effect changes in lymphocytes subpopulations and perforin expression at any time point. CONCLUSION Decreases of CD3+ cells on account of CD3+CD4+ subsets, and perforin expressing cells on account of CD3+CD8+ perforin+ cells were found in patients who had undergone on-pump CABG, but not in patients who had undergone off-pump CABG surgery, irrespectively of carbohydrate preoperative oral feeding.

Abstract
Acute myocardial infarction (AMI) occurs as a result of insufficient myocardial perfusion leading to cell necrosis. This is most commonly due to the obstruction of the coronary artery by ruptured atherosclerotic plaque and thrombosis. Damaged ischemic and necrotic myocardial cells release pro-inflammatory substances in tissue and plasma, leading to a systemic inflammatory response. Profound systemic inflammatory response during ischemia/reperfusion injury causes disruption of endothelial glycocalyx and detachment of endothelial cells that express von Willebrant factor (vWF). We hypothesize that circulating vWF+ endothelial cells could act as antigen presenting cells which interact with T and NK cells directly, by cell to cell contact and indirectly by cytokine and chemokine secretion, leading to the immune response towards inflammation. Analyzing the frequency, phenotype and pro-inflammatory substances produced in circulating vWF positive (+) cells in patients with AMI could be beneficial to determine the severity of the pro-inflammatory response, according to the level of endothelial dysfunction in the early period of AMI. To evaluate these hypotheses, we suggest to determine frequency, phenotype, and ability of cytokine/chemokine production in circulating vWF+ endothelial cells by simultaneous surface and intracellular cell staining, and flow cytometry analysis. Secretion of pro-inflammatory cytokines and chemokines, pro-atherogenic substances and the components of glycocalyx might be measured in supernatants of magnetically separated or sorted vWF+ endothelial cells, as well as in the serum of a patient with acute AMI by enzyme linked-immunoassay tests. The interaction of increasing concentrations of isolated circulating vWF+ endothelial cells and cognate T and NK cells might be investigated by lymphocyte proliferation rate, cytotoxic mediators' expression, and cytokine production. If our hypothesis is correct, characterization of circulating vWF+ endothelial cells could grant us greater insight into their role in pathophysiology of AMI and the degree of myocardial damage.

Abstract
PROBLEM Granulysin (GNLY) is a cytotoxic molecule mostly present in decidual natural killer (NK) cells. Blighted ovum (BO) and missed abortion (MA) represent the early pathological pregnancies with hindered development of the embryoblast or a dead embryo. We investigated the GNLY-mediated apoptotic mechanism potentially responsible for delayed termination of pregnancy. METHOD OF STUDY We performed immunohistological and immunofluorescence labeling of decidual tissues (GNLY, Apaf-1, NF-κB). NKG2A expression was analyzed by flow cytometry and GNLY mRNA by RT-qPCR. RESULTS The GNLY labeling intensity (H score) was lower in the nuclei of trophoblast cells in BO and MA. GNLY gene levels were inversely detected in BO and MA. A decreased decidual NK cell percentage was found in MA. NK cells from pathological pregnancies expressed lower NKG2A levels. The highest frequency of Apaf-1 was found in trophoblast cells of MA. NF-kB was highly expressed in decidual cells of BO. CONCLUSION The reduced activation of GNLY-mediated killing might be implicated in the slower rejection of trophoblast cells in BO and MA. A decreased authentic decidual NK cell number could be responsible for low cytotoxicity against trophoblast cells in MA. In BO, trophoblast cells have a higher survival potential due to increased NF-kB expression.

Abstract
Classical risk factors for endothelial dysfunction (ED), such as age, gender, total cholesterol, high-density lipoprotein cholesterol, systolic blood pressure, and smoking history are utilised for the Framingham score and Systemic Coronary Risk Estimation (SCORE) for evaluation of the 10-year cardiovascular risk in routine practice. Nonetheless, pro-inflammatory mediators are deeply involved in the initiation and the progression of ED and coronary artery disease (CAD), and act additionally or independently of metabolic factors before clinical manifestations of the disease appear. C-reactive protein, a marker of intimal thickening of the myeloid-related protein 8/14 heterodimer, monocyte chemotactic protein 1, interleukin-15, the cytotoxic mediator, granulysin, and the matrix metalloproteinase 9 could be valuable, single, fast, and non-invasive laboratory tools for ED deterioration degree assessment. We propose to investigate the impact of pro-inflammatory biomarkers on ED, measured by previously established clinical methods in patients with yet undiagnosed CAD and at medium risk for an acute coronary event. It could be useful to measure and correlate the concentration of particular inflammatory markers in peripheral blood samples and the results of the Framingham and SCORE charts, multi-slice computed tomography coronary angiography, echocardiography, brachial artery flow-mediated dilatation, carotid-femoral pulse wave velocity, ankle-brachial index, carotid wall thickening, myocardial perfusion scintigraphy, and particularly, cardiac magnetic resonance imaging. The goal would be that the degree of correlation between particular inflammatory markers and the results of some methods for the assessment of ED or cardiac ischaemic imaging could be emphasised and pro-inflammatory markers positioned in the pathogenetic algorithm of CAD.

Abstract
When medication management or percutaneous coronary intervention is not successful in patients with advanced ischemic heart disease, surgical revascularisation-predominantly coronary artery bypass grafting (CABG)-is considered the gold standard. However, CABG surgery can lead to ischemia/reperfusion injury, which is characterized by a strong inflammatory response. Interleukin (IL)-18, is a strong inflammatory mediator, that is released from cardiomyocytes and can be found in the systemic circulation of patients during and immediately after CABG surgery. The existing damage of endothelial glycocalyx in patients with ischemic heart disease is further impaired concurrently during the surgery due to the anaesthesia-surgical technique used and intravascular fluid loading. This results in the increased incidence of adverse events, including myocardial infarction. IL-18 leads to the activation of lymphocyte cytotoxicity via cytotoxic mediators (Fas ligand, Tumour necrosis factor (TNF)-related apoptosis-inducing ligand, perforin, and granulysin). We hypothesize that IL-18 is released locally in the heart and the systemic circulation in patients undergoing CABG surgery and may be correlated with the level of activity of circulating lymphocytes. In turn, this may lead to lymphocyte-mediated cytotoxicity directed toward damaged and activated endothelial cells. Shear stress glycocalyx, as well as damaged and activated endothelial cells then become the main the source of pro-inflammatory cytokines, chemokines, and adhesion molecules. These attract activated lymphocytes to adhere to the endothelium or enter the subintimal layer, increasing existing or initiating the formation of new plaques, which leads to the development of myocardial infarction during or shortly after surgery. To evaluate our hypothesis, we will measure the local concentration of IL-18 in the sinus coronarius and systemic circulation. These values will then be correlated with immunological and biochemical parameters, predominantly with the concentration of degradation products of glycocalyx and cytotoxic mediators in activated lymphocytes. If our hypothesis is correct, measuring the IL-18 concentration that is responsible for glycocalyx deterioration, may become a useful tool for predicting myocardial infarction occurrence in patients undergoing CABG surgery.

Abstract
PROBLEM Granulysin (GNLY) occurs in two forms, which have molecular weights of 9 and 15 kDa. We analyzed the cytotoxic potential of decidual lymphocytes (DLs) and peripheral blood lymphocytes (PBLs) based on the forms of GNLY that colocalizes with perforin (PER) and LAMP-1 following activation. METHODS The forms of GNLY were detected by using confocal microscopy. We investigated the colocalization with PER and LAMP-1 in freshly isolated and activated DLs and PBLs. RESULTS Activation of DLs and PBLs by K-562 cells increased the colocalization of 9 kDa GNLY with PER and LAMP-1. K-562 cells transfected with HLA-C decreased 9 kDa GNLY colocalization with PER in DLs only. IL-15 in DLs decreased 9 kDa GNLY and LAMP-1 colocalization, but increased both 15 kDa GNLY and LAMP-1, and PER and LAMP-1 colocalization. CONCLUSION Activated DLs and PBLs show greater cytotoxic potential based on increased colocalization of 9 kDa GNLY and PER. HLA-C and IL-15 affect DLs, indicating their role in maintaining the pregnancy tolerance.

Abstract
PROBLEM The role of HSP70 and both its constitutive (Hsc) and inducible (Hsp) forms in the pathogenesis of threatened spontaneous abortions was investigated. METHOD OF STUDY Immunohistology and/or immunofluorescence was used to analyze paraffin-embedded tissue sections, and reverse transcriptase-quantitative polymerase chain reaction and flow cytometry were used for analyses of decidual mononuclear cells (DMCs) and confocal microscopy for the detection of perforin, granulysin, and lysosome-associated membrane protein-1 (LAMP-1) in decidual lymphocytes (DLs). RESULTS The percentage of single Hsp70(+) , Hsc70(+) , and IL-15(+) cells and mRNA levels of HSP70, CD91, and TLR4 were lower in the decidua basalis in cases of threatened miscarriages compared to that in cases of normal pregnancy. In a suspension of normal DMCs, IL-15 significantly decreased the HSP70 members and TLR4 in dendritic cells, T cells, and NK cells while increasing CD91 in NK cells alone. CONCLUSION Downregulation of Hsc70, Hsp70, and IL-15 expression at gene and/or protein levels might support the retention of fertilization products in cases of missed abortion and blighted ovum.

Abstract
Increased presence of immune mediator and cytotoxic/apoptotic molecule granulysin was noticed in different tissues during pathological processes with the domination of Th1 over Th2 mediated immunity. Beside granulysin expression in T and NKT cells, activated NK cells are thought to be the major source of chemotactic 15 kDa and cytotoxic 9 kDa granulysin in vivo. As NK cells are the principal joint's tissue-infiltrating lymphocyte subset, we hypothesized that granulysin mediated human cell death (apoptosis) could be responsible for the relatively silent damage of the joint's tissue without clinically notable signs of systemic inflammation in the patients with osteoarthritis (OA). The analyzes of the presence and frequency of granulysin expressing lymphocytes at protein and gene levels in peripheral blood and synovial samples and/or the samples of joint's tissue after the joint replacement therapy in patients with OA could give the initial insight to evaluate our hypothesis. It would be of the particular interest to differentiate the expression of 9 kDa and 15 kDa granulysin forms in the effector cells, since only the shorter form exhibits cytotoxic properties. The measurement of granulysin mediated early apoptosis in human NK sensitive K562 cells could be suitable in vitro model for evaluating granulysin activity. Furthermore, disturbed balance of pro-inflammatory and anti-inflammatory cytokines in OA patients, could influence the level of the granulysin expression. Having in mind that the granulysin and its regulation is still unknown in the pathogenesis of OA, it could be worth to explore this important pro-inflammatory, cytotoxic/apoptotic mediator.

Abstract
We aimed to analyse granulysin (GNLY)-mediated cytotoxicity in the peripheral blood of patients with non-ST-segment elevation myocardial infarction (NSTEMI) treated with anti-ischaemic drug therapy. Thirty-nine NSTEMI patients with a median age of 70 years and 28 age-matched healthy subjects were enrolled in this study. On day 7 after MI, the number of GNLY(+) lymphocytes in the peripheral blood increased approximately six-fold of that in the healthy subjects, measured by flow cytometry. On day 14, the number of GNLY(+) cells significantly decreased in T, NKT, and both CD56(+dim) and CD56(+bright) NK subsets. GNLY(+) CD3(+) and GNLY(+) CD56(+) cells infiltrated central zone of myocardial infarction (MI). In persons who died in the first week after MI, GNLY(+) cells were found within accumulation of apoptotic leucocytes and reached the apoptotic cardiomyocytes in border MI zones probably due to the influence of interleukin-15 in peri-necrotic cardiomyocytes, as it is was shown by immunohistology. By day 28, the percentage of GNLY(+) lymphocytes in peripheral blood returned to the levels similar to that of the healthy subjects. Anti-GNLY mAb decreased apoptosis of K562 targets using peripheral blood NK cells from days 7 and 28 after MI, while in assays using cells from days 1 and 21, both anti-GNLY and anti-perforin mAbs were required to significantly decrease apoptosis. Using NK cells from day 14, K562 apoptosis was nearly absent. In conclusion, it seems that GNLY(+) lymphocytes, probably attracted by IL-15, not only participate partially in myocardial cell apoptosis, but also hasten resolution of cardiac leucocyte infiltration in patients with NSTEMI.

Abstract
PROBLEM The aim of the study was to assess possible binding of a mixture of constitutive Hsc70 and inducible Hsp70 forms (HSP70) to Toll-like receptor (TLR) 4 and CD91 receptors on decidual CD1a(+) dendritic cells (DCs) and their influence on DCs maturation status. METHOD OF STUDY Immunohistology and immunofluorescence of paraffin-embedded first trimetester and term pregnancy decidua were performed together with flow cytometry detection of antigens in DCs after stimulation of decidual mononuclear cells with HSP70. RESULTS Hsc70 and Hsp70 labeling revealed intracellular and nuclear staining in trophoblast cells. The numbers of Hsc70(+) and Hsp70(+) cells of decidual tissue were higher in early pregnancy decidua than in decidua at term. HSP70 binds CD91 and TLR4 receptors on CD1a(+) DCs and increased the expression of CD83, HLA-DR, CD80, and CD86, but decreased CC receptor (CCR) 5. HSP70 increased CC ligand (CCL) 3 and CCL22. HSP70 in the concentration of 1 μg/mL increased the percentage of interferon-γ and interleukin (IL)-15-expressing cells over the cells expressing IL-4. CONCLUSION HSP70 binds CD91 and TLR4 on decidual CD1a(+) DCs, causes their maturation, and increases IL-15 in the context of Th1 cytokine/chemokine domination, which could support immune response harmful for ongoing pregnancy.

Abstract
Endometrial adenocarcinoma is on the basis of the molecular, immunohistological and clinicopathologic features broadly divided into two groups, referred as type I and type II. Type I appears more frequently and in principle patients have a good prognosis; however a significant number of patients develop local recurrences. We hypothesize that TAG-72, expressed on endometrial carcinoma binds and internalizes endocytic pattern recognition receptors on surrounding tissue antigen presenting cells (dendritic cells and macrophages), powers their anti-inflammatory maturation program and make them capable to elicit or modulated tolerogenic immune response mediated by local T and NK effectors. This could support uncontrolled local tumor growth, deeper tumor invasion into surrounding tissues, frequent local recurrences and/or lymph node metastasis. To test this hypothesis, we propose a semi-quantitative immunohistochemical analysis of TAG-72 expression in endometrial adenocarcinoma samples and to correlate the results with clinical and pathological parameters (age, type and histological grade of the tumor, estrogen and progesterone receptor expression, invasion into the myometrium and capillaries, presence of lymph node metastases, FIGO stage, and TNM classification). It would be worthwhile to investigate the local tissue immune response in the tumor environment using tissue samples removed during surgery. These studies could elucidate the underlying immunopathological mechanisms that govern the early recurrence and possibly distant metastases of TAG-72-expressing adenocarcinomas and might help in deciding the type of treatment to be applied in a selected group of cancer patients including application of biological therapy with anti-TAG-72 antibodies, according the principle of personalized oncology treatments.

Abstract
Acute lymphoblastic leukaemia (ALL) is an aggressive disease. The course of disease is regulated by pro-inflammatory agents, and malignant cell infiltration of tissues plays a deleterious role in disease progression, greatly impacting quality of life, especially in the cognitive domains. Our hypothesis is that significant serum concentrations of interleukin 15 (IL-15) are responsible for higher expression of adhesion molecules on endothelial cells of blood-brain barrier (BBB) which allow leukaemia cells and/or normal lymphocytes the infiltration into the brain. In brain tissue these cells could be stimulated to release perforin and granulysin causing induction of apoptosis in brain cells that are involved in complex neural signalling mediated by neurotransmitters, and consequent fine cognitive impairment. Such changes could be detected early, even before notable clinical psycho-neurological or radiological changes in patients with ALL. To evaluate this hypothesis we propose measuring cognitive function using Complex Reactiometer Drenovac (CRD) scores in patients with ALL. The expression of different adhesion molecules on BBB as well as presence and distribution of different lymphocytes in brain tissue will be analyzed. We will then correlate CRD scores with levels of IL-15 and the percentages of T cells, natural killer T cells, and natural killer cells expressing perforin and/or granulysin proteins. CRD is a scientifically recognised and highly sensitive psychometric laboratory test based on the complex chronometric mathematical measuring of speed of reaction to various stimuli. It provides an objective assessment of cognitive functions from the most complex mental activities to the simplest reaction reflexes. Early recognition of cognitive dysfunction might be important when selecting the most appropriate chemotherapy and/or radiotherapy regimens, and could allow for the implementation of preventive measures against further deterioration in cognitive function and quality of life in patients with ALL.

Abstract
AIM Obesity is a well-known risk factor in the cardiovascular disease continuum. However, its clinical effects are multimodal, perplexed and non-unanimously understood. Our aim was to assess the prevalence and effects of obesity on the cardiometabolic risk factors and systolic function of left ventricle ejection fraction (LVEF) in patients scheduled for cardiovascular rehabilitation. METHODS A cohort of 302 consecutive patients recently treated for ischaemic or valvular heart disease was matched according to the existence of obesity, defined with body mass index (BMI ≥ 30 kg/m(2) ; n = 90 vs. 212), and the advanced grade of obesity (BMI ≥ 35 kg/m(2) ; n = 19 vs. 283). Nutritional risk screening was performed using the standardised NRS-2002 tool. RESULTS The mean age of patients was 62.4 ± 11.2 (range 23-86) years; there were more men than women 244 (80.8%) : 58 (19.2%). Group of obese conveyed higher prevalence of ischaemic heart disease than non-obese (OR = 2.69; 95% CI: 1.01-7.20; p = 0.048); while the difference was insignificant for the advanced grade of obesity (n = 17; 89.5%) vs. controls (n = 233; 82.3%; p > 0.05). There was no significant difference in prevalence of other comorbidities (diabetes, glucose intolerance, hypercholesterolaemia, chronic renal and chronic obstructive pulmonary disease) between studied groups (p > 0.05). Utilisation of lipid-lowering drugs was of similar range between the studied groups (p > 0.05), respectively. LVEF (%) was 50.5 ± 8.2 vs. 50.7 ± 7.7 (p > 0.05) and 50.6 ± 7.8 vs. 49.6 ± 10.9 (p > 0.05; Rho = 0.001; p > 0.05), respectively. CONCLUSION In studied set of patients, BMI positively correlated with left ventricle dimension and thickness. No significant connection of obesity was found with the prevalence of chronic comorbidities, increased nutritional risk, laboratory diagnostics or systolic function of left ventricle. Existence of obesity paradox in clinical practice was in part reaffirmed with our study.

Abstract
PROBLEM Differences in the expression of gp96 and its receptors were analysed in normal and pathological human pregnancy. MATERIAL AND METHODS Immunohistology and immunofluorescence of sections from decidual part of term placenta, first trimester normal decidua, missed abortion and blighted ovum decidua were performed together with reverse transcriptase-quantitative polymerase chain reaction and flow cytometry. RESULTS In missed abortion, gp96 was intensively stained, when compared to normal early pregnancy. The intensity of CD91 and TLR4 was higher in the first trimester pregnancy and blighted ovum, when compared to missed abortion. Decidual part of the term placenta is invaded with gp96⁺ , CD91⁺ and TLR4+ trophoblast. Progesterone-induced blocking factor (PIBF) decreased the frequency of TLR4⁺ T lymphocytes, CD91⁺ T, natural killer (NK) and mature dendritic cells after an 18-h culture. Decidual mononuclear cells (DMCs) treated with PIBF down-regulated CD91, TLR4 and gp96 gene expression. CONCLUSION The presence of gp96, CD91 and TLR4 at the maternal-foetal interface provides a molecular basis for their interaction, particularly in the absence of PIBF.

Abstract
INTRODUCTION This study aimed to assess whether heart fatty acid-binding protein (H-FABP) and glycogen phosphorylase isoenzyme BB (GPBB) could be used for the accurate diagnosis of acute myocardial infarction (AMI) in acute coronary syndrome (ACS) patients. MATERIALS AND METHODS The study included 108 ACS patients admitted to a coronary unit within 3 h after chest pain onset. AMI was distinguished from unstable angina (UA) using a classical cardiac troponin I (cTnI) assay. H-FABP and GPBB were measured by ELISA on admission (0 h) and at 3, 6, 12, and 24 h after admission; their accuracy to diagnose AMI was assessed using statistical methods. RESULTS From 92 patients with ACS; 71 had AMI. H-FABP and GPBB had higher peak value after 3 h from admission than cTnI (P = 0.001). Both markers normalized at 24 h. The area under the receiver operating characteristic curves was significantly greater for both markers in AMI patients than in UA patients at all time points tested, including admission (P < 0.001). At admission, the H-FABP (37%) and GPBB (40%) sensitivities were relatively low. They increased at 3 and 6 h after admission for both markers and decreased again after 24 h. It was 40% for H-FABP and approximately 2-times lower for GPBB (P < 0.01). In AMI patients, both biomarkers had similar specificities, positive- and negative-predictive values, positive and negative likelihood ratios, and risk ratios for AIM. CONCLUSION H-FABP and GPBB can contribute to early AMI diagnosis and can distinguish AMI from UA.

Abstract
PURPOSE The purpose of this study was to investigate the changes of cytotoxic protein-perforin in peripheral blood lymphocytes in severe TBI patients and possible correlation between severity of TBI and perforin expression. METHODS Flow cytometry was used for simultaneous detection of intracellular perforin and cell surface antigens of peripheral blood lymphocytes of 20 severe TBI patients on day 1, 4 and 7 after the onset of injury. Peripheral blood mononuclear cells from 20 healthy volunteers were used as control. Clinical and laboratory parameters were also recorded. RESULTS There was a statistically significant decrease of perforin-positive lymphocytes including T, natural killer (NK) and NKT cells on day 4 as compared with day 1 after the brain injury or healthy controls. On day 7, perforin expression was restored in lymphocyte of cytotoxic phenotype (CD8(+) T lymphocytes, NK cells, and NKT cells) compared with day 1. High positive correlation was found between the severity of TBI and frequency of perforin-positive cells on day 4 when the occurrence of the intra-hospital infections was the highest. CONCLUSION Severe TBI significantly decreases perforin expression in T lymphocytes, NK and NKT cells, which indicate a possible mechanism underlying the high susceptibility to infections.

Abstract
The aim of this investigation was to examine the role of perforin (P)-mediated cytotoxicity in the dynamics of tissue damage in patients with non-ST-segment elevation myocardial infarction (NSTEMI) treated with anti-ischaemic drugs. We enrolled 48 patients with NSTEMI in this study [age, 71.5 years; 61.5/76 (median, 25th/75th percentiles)]. The percentage of total peripheral blood P(+) lymphocytes was elevated owing to the increased frequency of P(+) cells within natural killer (NK) subsets, T and NKT cells in patients on day 1 after NSTEMI when compared with healthy controls. Positive correlations were found between cardiac troponin I plasma concentrations and the frequency of P(+) cells, P(+) T cells, P(+) NK cells and their CD56(+dim) and CD56(+bright) subsets during the first week after the NSTEMI. The expression of P in NK cells was accompanied by P-mediated cytotoxicity against K-562 targets at all days examined, except day 21, when an anti-perforin monoclonal antibody did not completely abolish the killing. The percentage of P(+) T cells, P(+) NKT cells and P(+) NK subsets was the highest on the day 1 after NSTEMI and decreased in the post-infarction period. CD56(+) lymphocytes were found in damaged myocardium, suggesting their tissue recruitment. In conclusion, patients with NSTEMI have a strong and prolonged P-mediated systemic inflammatory reaction, which may sustain autoaggressive reactions towards myocardial tissue during the development of myocardial infarction.

Abstract
Various positive effects of pet ownership on cardiovascular health are well known. The aim of this prospective and controlled longitudinal study was to determine the effects of everyday dog-walking on physical capacity in elderly patients during the first year after myocardial infarction. Regularly dog-walking for at least 15 minutes three times a day is related to significantly higher work load on the bicycle exercise test (72.5 +/- 10.75 versus 67.6 +/- 11.6 W p < 0.05) in the "dog-walking" group (N = 29, mean age 72.5 years) at 12 months compared to the control group (N = 30, mean age 71.7 years). Our results suggest that dogs may help to maintain continuous physical activity in elderly cardiovascular patients promoting their physical capacity. Further researches are needed to confirm this association as well to identify other possible influences of dog ownership on the cardiovascular health and on the outcome in patients after myocardial infarction.

Abstract
The objective of the present study was to investigate possible changes in granulysin (GNLY)-mediated cytotoxicity of peripheral blood lymphocytes in psoriatic arthritis (PsA) patients with respect to different phases of the disease. We prospectively enrolled 25 PsA patients in the active phase, 26 PsA patients in remission and 24 healthy controls. The simultaneous detection of intracellular GNLY and cell surface antigens (CD3 and CD56) was performed with flow cytometry. GNLY apoptotic protein was visualised by immunocytochemistry. Natural killer (NK) cell cytotoxicity was analysed with a cytotoxicity assay against human erythroleukaemia K-562 cells. The percentage of GNLY(+) cells did not differ significantly between PsA patients in the acute phase and those in remission; however, it was always higher than in healthy examinees due to the increased percentage of GNLY(+) cells within T cells, NKT cells, and both, and in the CD56(+dim) and CD56(+bright) NK subsets. The mean fluorescence intensity for GNLY was higher in all lymphocyte subpopulations in the acute phase than in remission and in healthy controls. Accordingly, GNLY-mediated NK cell cytotoxicity against K-562 cells of active phase PsA patients was significantly higher than that in patients in remission or in healthy controls. These findings demonstrated the involvement of GNLY in the worsening of PsA and suggested that GNLY mediated the development of joint lesions.

Abstract
PROBLEM Granulysin (GNLY) is a novel cytolytic protein lytic against a variety of tumor cells and microbes. The role of GNLY during pregnancy has not been extensively explored. The aim of this study is to examine GNLY expression and distribution in the first trimester pregnancy peripheral blood (PB) and decidua, the ability of decidual and PB natural killer (NK) cells to secrete GNLY spontaneously, and the role of antigen-presenting cells (APC) in the regulation of GNLY expression in decidual NK cells. METHOD OF STUDY GNLY expression was analyzed using cell permeabilization method, flow cytometry, and immunohistochemistry. GNLY secretion by purified NK cells was detected by ELISA method. RESULTS GNLY is abundantly expressed at the maternal-fetal interface in the first trimester pregnancy. Decidual T lymphocytes express significantly higher levels of GNLY (58%) then PB T lymphocytes (11%). Over 85% of decidual CD56(+) cells express GNLY and when cultured spontaneously release high quantities of GNLY. Decidual APC participate in the control of GNLY expression in CD56(+) cells. CONCLUSION Abundant expression of GNLY in the decidual immunocompetent cells and the capacity of decidual CD56(+) cells to spontaneously secrete high quantities of GNLY point to important protective and immunomodulatory role that this molecule could play at the maternal-fetal interface.

Abstract
PROBLEM The expression of cytotoxic/apoptotic mediators and the phenotype characteristics of uterine NK cells (uNK) in tubal ectopic pregnancy (EP) were investigated. METHOD OF STUDY Samples of uterine decidua and tubal mucosa as well as peripheral blood (PB) of the same women with EP were used for phenotype characterization of NK cells and detection of cytotoxic/apoptotic mediators and IL-15. RESULTS In tubal mucosa, perforin, FasL, granulysin and IL-15 were almost completely absent, but they were present in normal and EP uterine deciduas. TRAIL was present on trophoblast and tubal mucosa, contrary to its lack in normal and EP uterine decidua. CD16⁻ CD56(dim) NK cells, mostly CD94⁻ and NKG2A⁻, predominate in tubal mucosa, whereas CD16⁻ CD56(bright) NK cells, predominantly CD94(+) and NKG2A(+) prevail in EP uterine decidua. NK cells at the EP implantation site express lower percentages of perforin and granulysin, but they express a higher percentage of TRAIL than do EP uterine decidual and PB NK cells. Lower percentage of TNF-α-expressing and IL-4-expressing NK cells were found at the implantation site compared to EP uterine decidua. CONCLUSIONS Authentic uNK cell population seems to be insufficient to restrict trophoblast invasion because of low expression of cytotoxic/apoptotic mediators.

Abstract
Perforin is an important mediator of inflammatory reactions. It is a quick-action cytotoxic mediator accumulated in the cytoplasmic granules of effector immunity cells (T lymphocytes, NK and NKT cells) which provide death signal in infected or transformed cells. Perforin-positive cells were previously detected in myocardial tissue during Trypanosoma cruzi infection and viral myocarditis while its role in chronic and progressive cardiovascular inflammatory disease such as atherosclerosis is almost completely unexplored. The perforin activity is also untested during acute coronary events that represent unexpected atherosclerotic complications due to the inflammatory destabilisation and atherosclerotic plaque rupture. The aim of this study was to investigate the presence of perforin, an important immunological inflammatory molecule in peripheral blood lymphocytes during the early period after acute myocardial infarction. We analyzed three subject groups: women with ST-segment elevation acute myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI), conservatively treated women with acute myocardial infarction without ST-segment elevation (NSTEMI) and a control group of healthy volunteers. The STEMI and NSTEMI groups did not basically differ in medication neither in levels of routine laboratory tests, while troponin I were significantly higher in the STEMI group. In the study, we detected an early decrease of perforin-positive lymphocytes in STEMI patients that were in contrast with their persisting elevation among NSTEMI patients. Despite greater myocardial necrosis in the STEMI group, results of this pilot-study indicated the prolonged perforin-mediated inflammatory response in patients with NSTEMI. This perforin down-regulation that follows the coronary interventional reperfusion in STEMI emphasized the possible anti-inflammatory role of primary PCI among patients with acute myocardial infarction. Given that the issue of routine primary PCI in NSTEMI is nowadays highly topical, the results we expect in the wake of this pilot study could demonstrate a significant impact on clinical practice. Further research is needed to confirm these results, compare the perforin-mediated activity to other inflammatory mediators in acute coronary events and to examine their impact on the long-term outcome.

Abstract
Tumor-associated glycoprotein-72 (TAG-72) is physiologically present in secretory phase endometrium, but its presence and possible immunological role in early normal human pregnancy decidua has not received attention. The double labeling of paraffin-embedded early pregnancy decidua sections using B-72.4 anti-TAG-72 mAb and MNF 116 anti-cytokeratin mAb revealed the absence of TAG-72 in uterine decidua of normal and pathological pregnancies (non-embryonic pregnancy and missed abortion) at the implantation sites, although it was present in epithelial cells at and away from the tubal implantation site of an ectopic pregnancy. TAG-72 binds and internalizes by reacting with the mannose receptor (MR-CD206) or with DC-specific ICAM reacting non-integrin (DC-SIGN-CD209) on decidual CD1a+ cells. Decidual CD1a+ cells stimulated with TAG-72 decreased CD83 expression and diminished IL-15 and IFN-γ intracellular production. TAG-72-treated CD1a+ cells decreased IFN-γ production in syngenic decidual and allogenic cord blood T cells even in the presence of lipopolysaccharide. TAG-72- and lipopolysaccharide-pre-treated CD1a+ cells significantly increased IL-4 expression in allogenic cord blood T cells. TAG-72 increased allogenic cord blood T cell proliferation, mediated by decidual CD1a+ cells, compared with its effect on the proliferation of syngenic decidual T cells. All these data emphasize the anti-inflammatory properties of TAG-72-treated decidual CD1a+ cells in terms of their interaction with T cells. Thus, the absence of TAG-72 at the maternal-fetal interface during early pregnancy could lead to a mild pro-inflammatory response that may be beneficial for pregnancy success and trophoblast growth control.

Abstract
Infections are leading causes of increased morbidity and mortality of severe traumatic brain-injured (STBI) patients. The mechanism underlying the susceptibility to the infections is still unexplained. The purpose of the study was to investigate changes in frequency of leucocytes subpopulations in peripheral blood of patients with STBI during the course of intensive care treatment. Twenty patients with STBI were included in the study. Healthy age- and sex- volunteers served as control. Peripheral blood samples were taken from these patients at day 1, 4 and 7, and peripheral blood mononuclear cells (PBMC) were isolated. The percentage of T, B lymphocyte, NK and NKT cells as well as monocytes was analysed by simultaneous detection of surface antigens using fluorochrome-conjugated monoclonal antibodies. The two major subsets of T lymphocytes (CD3(+)CD56(-)CD4(+) and CD3(+)CD56(-)CD8(+)) and NK cells (CD3(-)CD56(+dim) and CD3(-)CD56(+bright)) were also analysed by flow cytometry. Extracranial infections were presented in 55% patients with STBI. At day 4, the percentage of T lymphocytes with cytotoxic phenotype significantly diminished and their numbers restored at day 7. The frequency of NKT cells showed the identical time-dependent pattern, whereas the percentage of NK cells diminished on day 4 but did not restore after 7 days. The frequency of B lymphocytes did not change significantly during the time investigated, whereas the percentage of monocytes increased immediately after the injury and gradually diminished. The decrease in cells with cytotoxic phenotype might explain high incidence of susceptibility to infection of patients with STBI.

Abstract
PROBLEM Dendritic cells (DC)/natural killer (NK) cells interactions in the deciduas of early human pregnancies were analyzed in vitro. METHOD OF STUDY Phenotype, cytokine expression and/or cytolytic mediators' expression were measured by flow cytometry in NK and DC from the freshly isolated decidual mononuclear cells or after their purification and co-culture in vitro. Proliferation of 5(6)-Carboxyfluorescein diacetate N-succinimidyl ester (CFSE)-labeled CD56(+) cells was analyzed by flow cytometry after the co-culture with CD1a(+) or CD83(+) DC. RESULTS Decidual CD1a(+) cells show less mature phenotype with no expression of CD197, lower expression of CD80 and CD86 and higher expression of CD206 and CD195 in comparison to CD83(+) cells. Interleukin (IL)-15, interferon-gamma and tumor necrosis factor-alpha productions were higher in immature than mature DC, whereas IL-10 and IL-18 were equally produced in both subpopulations. Immature DC increase perforin, FasL and TRAIL protein expression and proliferation of NK cells, but decrease their intracellular IL-15 production. Mature DC caused less efficient proliferation of NK cells, and did not affect cytokine and cytolytic mediator expression. CONCLUSION These results suggest that decidual CD1a(+) cells regulate and shape NK cell function more profoundly than CD83(+) cells in decidua.

Abstract
During pregnancy, a delicate balance of innate and adaptive immune responses at the maternal-fetal interface promotes survival of the semi-allogeneic embryo and, at the same time, allows effective immunity to protect the mother from environmental pathogens. As in other tissues, antigen handling and processing in the decidualized endometrium constitutes a primary event in the onset of immune responses and is therefore likely to determine their stimulatory or tolerogenic nature. Maternal antigen-presenting cells [macrophages and dendritic cells (DCs)] are scattered throughout the decidualized endometrium during all stages of pregnancy and appear to be important players in this feto-maternal immune adjustment. This review focuses on the characterization of decidual macrophages and DCs, as well as their involvement in cell-cell interactions within the decidual leukocyte network, which are likely to influence uterine and placental homeostasis as well as the local maternal immune responses to the fetus during pregnancy.

Abstract
BACKGROUND Perforin is a membrane-disrupting protein that allows the entry of granzymes into a target cell inducing degradation of target substances in the cytoplasm and nucleus thus leading to programmed cell death or apoptosis. Recent work demonstrated a possible involvement of perforin mediated cytotoxicity in immunopathogenesis of psoriasis. OBJECTIVES To investigate a difference in systemic (peripheral blood) and local (lesions) expression and distribution of perforin in psoriatic patients with severe and mild disease. METHODS Flow cytometry was used for simultaneous detection of intracellular (perforin) and cell surface antigens in peripheral blood lymphocytes. The expression of perforin in skin lesions was evaluated by immunohistochemistry. RESULTS Significant increase of perforin expression in T lymphocytes, especially cytotoxic CD8+ cells was found in severe psoriasis compared to mild disease (p<0.01 and p<0.05, respectively). There was also an increase of CD56+P+ NK cells (p<0.05) in severe compared to mild psoriasis. The psoriatic plaque of both, severe and mild disease were abundant with perforin showing no significant difference on local level. CONCLUSION Based on our results we suggest the association between perforin expression and disease severity.

Abstract
Decidual natural killer (NK) cells are the predominant lymphocytes at the maternal-fetal interface. They are involved in defense against virally infected, parasitized and transformed cells and may contribute to the control of trophoblast invasion. The presence of perforin and other possible cytolytic mediators suggests these functions. Cytolytic mechanisms of unstimulated and Th1 cytokine stimulated decidual lymphocytes (DL), as well as purified decidual CD56(+) cells, were analyzed against NK sensitive and resistant targets. DL were isolated from decidual mononuclear cells (DMC) cultured in the medium only or in the presence of Th1 cytokines: IL-2, IL-12, IL-15, IL-18 and their combinations (IL-12/IL-18 or IL-15/IL-18). Fas ligand (FasL), perforin and granzyme B mRNAs expression and cytotoxicity were analyzed by flow cytometry and/or RT-PCR. DL (containing 72.19+/-7.53% of CD56(+) cells), obtained from 18h-cultured DMC in the medium only, expressed perforin, FasL and granzyme B mRNAs and lysed the NK-sensitive K-562 cell line, and also the NK-resistant P815 and P815-Fas transfected cell lines. Concanamycin A, a blocker of granule exocytosis, decreased significantly K-562 lysis, but not P815 lysis. However, the addition of anti-FasL antibody diminished significantly P815 lysis as well. IL-2 and IL-15, known inducers of perforin and FasL mRNAs and protein expression, could not additionally increase P 815 cell lysis by DL cultured within DMC. These results suggest that DL cultured in DMC for 18h, have the characteristics of lymphokine-activated killer (LAK) cells and are able to use efficiently both the perforin and the FasL cytolytic pathways.

Abstract
Human decidual NK cells are massively recruited at the site of embryonic implantation (decidua basalis). They differ in many ways from their peripheral blood NK cell counterparts in terms of gene expression, phenotype and functionality. The major subpopulation of decidual NK cells is CD56(bright) whereas the minor subset is CD56(dim), contrasting with the peripheral blood NK cells whose major subpopulation is CD56(dim). Decidual NK cell cytolytic function is much reduced despite the presence of several activating receptors and the essential machinery required for lysis. Decidual NK cells produce a number of cytokines that are not normally secreted by peripheral blood NK cells. Human decidual NK cell potential functions at the maternal-fetal interface are not yet clearly established but several hypotheses are being evaluated, including control of extravillous invasion, control of uterine vascular remodeling, and local anti-viral activity.

Abstract
PROBLEM We investigated whether decidual adherent cells (DAC) and interleukin (IL)-15, in comparison to interleukin (IL)-2 affect cytolytic potential of first trimester decidual lymphocytes (DL). METHOD OF STUDY Decidual mononuclear cells were obtained by enzymatic digestion and density gradient centrifugation. Non-adherent DL were collected after 2-hr adherence and cultured for 18 or 72 hr with: IL-15 (0.5-5 ng/mL), IL-2 (100-1000 U/mL) or both of these cytokines, DAC (ratio 3:1 and 1:1) or DAC and anti-IL-15 antibody. Perforin, Fas ligand (FasL) and granzyme B were detected at mRNA level in indicated culture conditions. Cytolytic activity of DL against K-562, P815 and P815-Fas was measured by 2-hr PKH-26 cytotoxicity assay. The dynamics of perforin protein and mRNA expression were measured in DL after a contact with K-562 targets. RESULTS Interleukin-15 enhanced perforin, FasL and granzyme B transcription after 18-hr culture and prevented perforin protein downregulation, observed after DL culture. IL-2 had similar effects. DAC sustained perforin expression in DL and anti-IL-15 monoclonal antibody abrogated this effect. DAC increased cytotoxicity of DL against K-562 which was mediated by IL-15. CONCLUSION Interleukin-15, probably produced by DAC, upregulates cytolytic mediators' expression and perforin-mediated cytotoxicity of DL, with equal efficiency as high concentrations of IL-2.

Abstract
The immunogenetic enigma of maternal acceptance of the fetal semiallograft has been termed an immunological paradox. The first trimester decidua is heavily infiltrated with CD56(bright) CD16- uterine natural killer (uNK) cells which must be prepared to respond to potential pathogen challenges and still be able to control immune responses that allow the development of the fetus. The significant presence of cytolytic mediators, perforin and Fas/Fas ligand (FasL), at the maternal-fetal interface raises a question of their role(s) in the immunological interrelations between maternal tissues and trophoblast cells. As uNK cells in vitro lyse target cell lines (K562, P815 and P815Fas) using these effector molecules, it seems that, although immunocompetent, their cytotoxicity is not directed against trophoblast during normal pregnancy. Therefore, it is generally believed that the hormonal and Th1/Th2 cytokine balance plays an important role in the tolerance and maintenance of pregnancy. This paper gives an overview of the recent findings on the complex immunological events that occur at the maternal-fetal interface.

Abstract
BACKGROUND The mannose receptor (MR) is involved in the initiation of the immune response and regulation of homeostasis during inflammation and tissue remodeling. METHODS Distribution, endocytosis and possible natural ligand tumor associated glycoprotein-72 (TAG-72) for the MR have been examined by immunohistology, immunocytochemistry and flow cytometry at the maternal-fetal interface, characterized by extensive tissue remodeling. RESULTS Contrary to disseminated distribution of the MR positive (MR+) cells in term placenta, the MR+ cells of early pregnancy decidua intimately surrounded glands and followed tissue distribution of CD14 positive cells. The mannose receptor was present on freshly isolated first trimester decidual mononuclear cells and distributed mostly on macrophages (77.08 +/- 10.55%, mean +/- SD). The expression of the MR on CD14 positive cells decreased following 18 h culture (P < 0.01) and was accompanied by the reduction of fluorescein isothiocyanate (FITC)-dextran uptake. PAM-1 anti-MR antibody, mannan and TAG-72 reduced FITC-dextran uptake by decidual macrophages. CONCLUSIONS These data indicate that the MR+ macrophages, surrounding early decidual glands, are able to internalize ligands for carbohydrate recognition domain of the receptor, including decidual secretory phase mucin TAG-72.
