Abstract
Periodontal disease is a broad term given when the periodontium is affected by inflammation. There are several methods to diagnose periodontitis, but no method to quantify the cancellous bone is presently used. For this purpose, a non-invasive tool that is efficient in analyzing bone quality called fractal analysis can be employed. The objective of the study was to utilize fractal dimension (FD) to evaluate cancellous patterns of interproximal alveolar bone using a digital intraoral periapical radiograph (IOPAR) in different clinical presentations of periodontitis classified according to the latest classification by the World Workshop for Periodontal and Peri-Implant Diseases and Conditions, 2017 (WWDC, 2017). The study aimed to numerically calculate the periodontitis changes in the cancellous bone around the affected tooth on an IOPAR using fractal analysis and to provide an additional criterion for the staging of periodontitis. In this cross-sectional observational study, 75 patients were selected and equally allotted to five groups based on the staging system proposed by the WWDC, 2017. The region of interest was selected on the IOPA radiograph of the tooth with the site having the most significant clinical attachment loss, and FD was calculated using Image J analysis. The association of gender and age with stages of periodontitis was studied using the chi-square test of independence. A comparison of % bone loss and fractal dimension among stages was studied by using the non-parametric Kruskal Wallis test. The relationship between % bone loss and fractal dimension within stages and gender was studied by using the Karl Pearson correlation. A receiver operating characteristic (ROC) curve analysis was performed for FD value as a marker of periodontitis patients. We demonstrated that the FD values decreased significantly with the increase in stages (p < 0.0001). The overall relationship between % bone loss and FD showed a significantly strong negative correlation of -0.739 (p < 0.0001), except for stages III and IV. FD can be utilized as a quantitative method for detecting cancellous bone changes in different stages of periodontitis, aiding in diagnosing periodontitis.

Abstract
The objective of the study was to compare the expression of immunohistochemical (IHC) markers of oral submucous fibrosis (OSMF) (non-transformed group) to those of oral squamous cell carcinoma (OSCC) transformed from OSMF (transformed group). The search for comparative cross-sectional studies was carried out in PubMed and Scopus abiding to the PICO criteria, where expression of IHC markers in OSMF were compared with that of OSCC transformed from OSMF. The cellular distribution, number of positive cases, staining intensity, and mean immunoreactive score (IRS) of each IHC marker were evaluated in both groups. A total of 14 studies were included in the systematic review, in which immunoexpression of 15 epithelial and 4 connective tissue biomarkers were evaluated. Expression of β1-integrin, OCT-3, CD1a, CD207, survivin, Dickkopf-1, COX-2, hTERT, CTGF, MDM2, Ki-67, and α-SMA were increased during transformation of OSMF to OSCC. Conversely, expression of PTEN and lysyl oxidase decreased during transformation of OSMF to OSCC. Expression of a group of epithelial markers, such as COX2, hTERT, CTGF, survivin, MDM2, and p53, was 38 times lower in the non-transformed group cases compared to transformed group cases (95% CI: 58% to 10%; p = 0.01; and I2 = 90%). Meta-analysis of all markers involved in cell metabolism/apoptosis, which included β1-integrin along with the above markers also suggested 42 times lower expression in the non-transformed group as compared to the transformed group (95% CI: 58% to 10%; p = 0.01; and I2 = 90%). Sub-group analyses on cytoplasmic and nuclear epithelial markers were inconclusive. Meta-analysis of connective tissue markers was also inconclusive. No publication bias was found. Instead of delving into numerous markers without a strong basis for their use, it is advisable to further study the markers identified in this study to explore their clinical utility.

Abstract
PURPOSE This study aimed to evaluate the impact of dietary supplementation with omega-3 polyunsaturated fatty acids (PUFAs) eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) combined with scaling and root planing (SRP) in untreated periodontitis stage III and IV. METHODS Forty patients were randomly assigned to the test group receiving SRP plus omega-3 PUFAs (n = 20) or control group receiving SRP alone (n = 20). Clinical changes of pocket probing depths (PD), clinical attachment level (CAL), bleeding on probing (BOP) and rates of closed pockets (PPD ≤ 4 mm without BOP) were evaluated at baseline and after 3 and 6 months. Phorphyromonas gingivalis, Tanarella forsythia, Treponema denticola and Aggregatibacter actinomycetemcomitans counts were analysed at baseline and at 6 months. Serum was subjected to lipid gas chromatography/mass spectrometry analysis at baseline and at 6 months. RESULTS Significant improvement of all clinical parameters at 3 and 6 months was observed in both groups. For the primary outcome "change of mean PD," no significant difference was detected between the groups. Patients treated with omega-3 PUFAs demonstrated significantly lower rates of BOP, higher gain of CAL and higher number of closed pockets at 3 months in comparison to the control group. After 6 months, no clinical differences between the groups were found, with the exception of lower BOP rates. Moreover, in the test group, the number of key periodontal bacteria was significantly lower than in the control group at 6 months. Increased proportions of serum n-3 PUFAs and decreased proportions of n-6 PUFAs were detected at 6 months in the patients from the test group. CONCLUSION High-dose omega-3 PUFA intake during non-surgical treatment of periodontitis results in short-term clinical and microbiological benefits. The study protocol was approved by the ethical committee of Medical University of Lodz (reference number RNN/251/17/KE) and registered at clinicaltrials.gov (NCT04477395) on 20/07/2020.

Abstract
The objective was to evaluate the association of the immunoexpression of cancer stem cell (CSC) markers with clinicopathological and survival outcomes in tongue squamous cell carcinoma (TSCC) patients. This systematic review and meta-analysis [PROSPERO (CRD42021226791)] included observational studies that compared the association of clinicopathological and survival outcomes with CSC immunoexpression in TSCC patients. Pooled odds ratios (ORs) and hazard ratios (HRs) with 95% confidence intervals (CI) were used as outcome measures. Six studies identified the association with three surface markers (c-MET, STAT3, CD44) and four transcription markers (NANOG, OCT4, BMI, SOX2). The odds of early-stage presentation were 41% (OR = 0.59, 95% CI 0.42-0.83) and 75% (OR = 0.25; 95% CI 0.14-0.45) lower in CSC and SOX2 immuno-positive cases than immuno-negative cases, respectively. The odds of well-differentiated tumors in transcription marker immuno-positive cases were 45% lower compared to immuno-negative cases (OR = 0.55, 95% CI 0.32-0.96). The odds of positive lymph nodes were 2.01 times higher in CSC immuno-positive cases compared to immuno-negative cases (OR = 2.01, 95% CI 1.11-3.65). Mortality in immuno-positive cases was 121% higher than that in immuno-negative cases (HR = 2.21; 95% CI 1.16-4.21). Advanced tumor staging and grading, lymph node metastasis, and mortality were significantly associated with positive immunoexpression of CSC markers.

Abstract
The JAK/STAT signal pathway is a system of intracellular proteins used by many cytokines and growth factors to express genes responsible for the process of cell activation, proliferation and differentiation. There has been numerous inflammatory and autoimmune diseases identified where the JAK/STAT signaling is disrupted; however, there are only a few papers concerning autoimmune bullous diseases published. The aim of this study was to evaluate the expression of proteins: JAK3, STAT2, STAT4 and STAT6 in epithelium lesions in patients with pemphigus vulgaris (PV), bullous pemphigoid (BP), oral lichen planus (LP) and chronic ulcerative stomatitis (CUS), as well as in the control group. Immunohistochemistry and immunoblotting were used to evaluate expression of selected proteins. We found significantly higher expression of selected JAK/STAT proteins in oral mucosa lesions in study groups in comparison to the control group, which indicates participation of JAK/STAT pathway in pathogenesis of these diseases. In BP and PV there were no increased STAT2 expression, whereas in CUS and LP no increased STAT4 expression occurred. The differences in expression of JAK/STAT proteins in selected disorders have been observed. These results create new potential therapeutic targets for the treatment.

Abstract
The blood–brain barrier (BBB) tightly controls the microenvironment of the central nervous system (CNS) to allow neurons to function properly. Additionally, emerging studies point to the beneficial effect of natural oils affecting a wide variety of physiological and pathological processes in the human body. In this study, using an in vitro model of the BBB, we tested the influence of natural fish oil mixture (FOM) vs. borage oil (BO), both rich in long-chain polyunsaturated fatty acids (LC-PUFAs) and monounsaturated fatty acids (MUFAs) such as oleic acid (C18:1n9c) or nervonic acid (NA), on human oligodendrocyte precursor cells (hOPCs) during their maturation to oligodendrocytes (OLs) regarding their ability to synthesize myelin peptides and NA. We demonstrated that FOM, opposite to BO, supplemented endothelial cells (ECs) and astrocytes forming the BBB, affecting the function of hOPCs during their maturation. This resulted in improved synthesis of myelin basic protein (MBP), myelin oligodendrocyte glycoprotein (MOG), proteolipid protein (PLP), and NA in mature OLs. This effect is probably the result of BBB cell and hOPC stimulation via free fatty acid receptors (FFARs), which increases insulin growth factor-1 (IGF-1), ciliary neurotrophic factor (CNTF), and brain-derived neurotrophic factor (BDNF) and inhibits fibroblast growth factor 2 (FGF-2) synthesis. The unique formula of fish oil, characterized by much more varied components compared to those of BOs, also improved the enhancement of the tight junction by increasing the expression of claudin-5 and VE-cadherin on ECs. The obtained data justify consideration of naturally derived fish oil intake in human diet as affecting during remyelination.

Abstract
Neutrophils are a heterogenous population capable of both antimicrobial functions and suppressor ones, however, no specific pattern of transcription factors controlling this plasticity has been identified. We observed rapid changes in the neutrophil status after stimulation with LPS, pre-activating concentration of TNF-α, or IL-10. Chromatin immunoprecipitation sequencing (ChIP-Seq) analysis of histone H3K4me3 allowed us to identify various transcriptional start sites (TSSs) associated with plasticity and heterogeneity of human neutrophils. Gene Ontology analysis demonstrated great variation within target genes responsible for neutrophil activation, cytokine production, apoptosis, histone remodelling as well as NF-κB transcription factor pathways. These data allowed us to assign specific target genes positioned by H3K4me3-marked histone with a different pattern of gene expression related to NF-κB pathways, apoptosis, and a specific profile of cytokines/chemokines/growth factors realised by neutrophils stimulated by LPS, IL-10, or TNF-α. We discovered IL-10-induced apoptotic neutrophils being transcriptionally active cells capable of switching the profile of cytokines/chemokines/growth factors desired in resolving inflammation via non-canonical NF-κB pathway with simultaneous inhibition of canonical NF-κB pathway. As apoptotic/suppressive neutrophils induced by IL-10 via positioning genes within H3K4me3-marked histone were transcriptionally active, newly described DNA binding sites can be considered as potential targets for immunotherapy.

Abstract
Peripheral neutrophils in HIV-infected individuals are characterized by impairment of chemotaxis, phagocytosis, bactericidal activity, and oxidative burst ability regardless of whether patients are receiving antiretroviral therapy or not. Neutrophil dysfunction leads not only to increased susceptibility to opportunistic infections but also to tissue damage through the release of reactive oxygen species (ROS), proteases, and other potentially harmful effector molecules contributing to AIDS progression. In this study, we demonstrated high levels of histone H3 lysine K4 trimethylated (H3K4me3) and dysregulation of DNA transcription in circulating neutrophils of HIV-infected subjects. This dysregulation was accompanied by a deficient response of neutrophils to LPS, impaired cytokine/chemokine/growth factor synthesis, and increased apoptosis. Chromatin immunoprecipitation sequencing (ChIPseq) H3K4me3 histone analysis revealed that the most spectacular abnormalities were observed in the exons, introns, and promoter-TSS regions. Bioinformatic analysis of Gene Ontology, including biological processes, molecular function, and cellular components, demonstrated that the main changes were related to the genes responsible for cell activation, cytokine production, adhesive molecule expression, histone remodeling via upregulation of methyltransferase process, and downregulation of NF-κB transcription factor in canonical pathways. Abnormalities within H3K4me3 implicated LPS-mediated NF-κB canonical activation pathway that was a result of low amounts of κB DNA sites within histone H3K4me3, low NF-κB (p65 RelA) and TLR4 mRNA expression, and reduced free NF-κB (p65 RelA) accumulation in the nucleus. Genome-wide survey of H3K4me3 provided evidence that chromatin modifications lead to an impairment within the canonical NF-κB cell activation pathway causing the neutrophil dysfunction observed in HIV-infected individuals.

Abstract
Periodontitis is a chronic multifactorial inflammatory disease that leads to the loss of supportive tissues around the teeth with gradual deterioration of masticatory function and esthetics, resulting eventually in the decrease of the life quality. Host immune response triggered by bacterial biofilm is responsible for the chronic periodontal inflammation and ongoing tissue loss. Omega-3 polyunsaturated fatty acids (PUFA) such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have anti-inflammatory properties, thus may be used for the treatment of chronic inflammatory diseases. In this study, we aimed to evaluate the effect of dietary supplementation with omega-3 PUFA in the patients with stage III and IV periodontitis. Thirty otherwise healthy patients were treated with scaling and root planning (SRP). In the test group (n = 16), patients were additionally supplemented with 2.6 g of EPA and 1.8 g of DHA. In the control group (n = 14), patients received only SRP. Periodontal examination was performed at baseline and three months following initial therapy. Salivary samples were taken twice at baseline and at the end of the experiment. We found that there was a statistically significant reduction in the bleeding on probing (BOP) and improvement of clinical attachment loss (CAL) at three months in the test group compared to the control group. Moreover, a statistically significant higher percentage of closed pockets (probing depth ≤ 4 mm without BOP) was achieved in the test group vs. control group after three months of treatment. Accordingly, the levels of pro-inflammatory cytokines/chemokines interleukin (IL)-8 and IL-17 were markedly lower, while the level of anti-inflammatory IL-10 was significantly higher in the salivary samples of the patients supplemented with omega-3 PUFA at three months in comparison to the patients treated with SRP alone. Our findings demonstrate that dietary intervention with high-dose of omega-3 PUFA during non-surgical therapy may have potential benefits in the management of periodontitis.

Abstract
The critical aspect in multiple sclerosis (MS) progression involves insufficient regeneration of CNS resulting from deficient myelin synthesis by newly generated oligodendrocytes (OLs). Although many studies have focused on the role of autoreactive lymphocytes in the inflammatory-induced axonal loss, the problem of insufficient remyelination and disease progression is still unsolved. To determine the effect of myelin-specific lymphocytes on OL function in MS patients and in a mouse model of MS, we cultured myelin induced MS CD49d+CD154+ circulating lymphocytes as well as Experimental Autoimmune Encephalomyelitis (EAE) mouse brain-derived T and memory B cells with maturing oligodendrocyte precursor cells (OPCs). We found that myelin-specific CD49d+CD154+ lymphocytes affected OPC maturation toward formation of immune reactive OLs. Newly generated OLs were characterized by imbalanced myelin basic protein (MBP) and proteolipid protein (PLP) production as well as proinflammatory chemokine/cytokine synthesis. The analysis of cellular pathways responsible for OL reprogramming revealed that CD49d+CD154+ lymphocytes affected miRNA synthesis by dysregulation of polymerase II activity. miR-665 and ELL3 turned out to be the main targets of MS myelin-specific lymphocytes. Neutralization of high intracellular miR-665 concentration restored miRNA and MBP/PLP synthesis. Together, these data point to new targets for therapeutic intervention promoting CNS remyelination.

Abstract
The dysfunction of oligodendrocytes (OLs) is regarded as one of the major causes of inefficient remyelination in multiple sclerosis, resulting gradually in disease progression. Oligodendrocytes are derived from oligodendrocyte progenitor cells (OPCs), which populate the adult central nervous system, but their physiological capability to myelin synthesis is limited. The low intake of essential lipids for sphingomyelin synthesis in the human diet may account for increased demyelination and the reduced efficiency of the remyelination process. In our study on lipid profiling in an experimental autoimmune encephalomyelitis brain, we revealed that during acute inflammation, nervonic acid synthesis is silenced, which is the effect of shifting the lipid metabolism pathway of common substrates into proinflammatory arachidonic acid production. In the experiments on the human model of maturating oligodendrocyte precursor cells (hOPCs) in vitro, we demonstrated that fish oil mixture (FOM) affected the function of hOPCs, resulting in the improved synthesis of myelin basic protein, myelin oligodendrocyte glycoprotein, and proteolipid protein, as well as sphingomyelin. Additionally, FOM reduces proinflammatory cytokines and chemokines, and enhances fibroblast growth factor 2 (FGF2) and vascular endothelial growth factor (VEGF) synthesis by hOPCs was also demonstrated. Based on these observations, we propose that the intake of FOM rich in the nervonic acid ester may improve OL function, affecting OPC maturation and limiting inflammation.

Abstract
Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune neuroinflammatory disease. In contrast to multiple sclerosis, autoantibodies against aquaporin-4 (AQP4) expressed on astrocytic end-feet have been exclusively detected in sera of NMOSD patients. Several lines of evidence suggested that anti-AQP4 autoantibodies are pathogenic, but the mechanism triggering inflammation, impairment of astrocyte function, and the role of neutrophils presented in NMOSD cerebrospinal fluid remains unknown. In this study, we tested how human neutrophils affect astrocytes in the presence of anti-AQP4 Ab-positive serum derived from NMOSD patients. An in vitro model of inflammation consisted of human astrocyte line, NMOSD serum, and allogenic peripheral blood neutrophils from healthy individuals. We showed evidence of pathogenicity of NMOSD serum, which by consecutive action of anti-AQP4 Abs, complement system, and neutrophils affected astrocyte function. Anti-AQP4 Ab binding astrocytes initiated two parallel complementary reactions. The first one was dependent on the complement cytotoxicity via C5b-9 complex formation, and the second one on the reverse of astrocyte glutamate pump into extracellular space by C5a-preactivated neutrophils. As a consequence, astrocytes were partially destroyed; however, a major population of astrocytes polarized into proinflammatory cells which were characterized by pathological glutamate removal from extracellular space.

Abstract
This study tested the hypothesis that CD4(+)CD25(+)CD127(low) regulatory T (Treg) cells might induce immunosuppressive properties in apoptotic neutrophils. Treg cells are recognized as a major subset of immune cells possessing potent suppressive properties directed at T effector cells. However, Treg cells have recently been found to inhibit neutrophil function and promote their apoptosis. One of the mechanisms of action of Treg cells is the induction of other suppressor cell populations according to an infectious tolerance model. We showed that LPS-activated Treg cells promote generation of IL-10 and TGF-β1, inhibit IL-6 production by PMNs and induce the expression of heme oxygenase-1 (HO-1) and the suppressor of cytokine signaling 3 molecule (SOCS3). However, CD3/CD28-activated Treg cells were seen to promote TGF-β1 production, as well as IDO and HO-1 expression by PMNs. These findings suggest that Treg cells might play an important role in the direct control of innate immune responses through the induction of neutrophils with immunosuppressive properties that generate IL-10, TGF-β1, IDO and HO-1.

Abstract
BACKGROUND Recurrent aphthous stomatitis (RAS) is a chronic inflammatory disease of unknown etiology characterized by recurring formation of painful oral ulcers. RAS may result from oral epithelium damage caused by T-cell-mediated immune response. CD4(+)CD25(+) T regulatory (Treg) cells suppress proliferation and effector functions of other immune cells, and therefore are crucial in regulating the immune response. METHODS We tested the function of peripheral CD4(+)CD25(high) Treg cells in active RAS through their ability to inhibit proliferation and cytokine production of conventional CD4(+) T cells. We also attempted to detect the presence of FOXP3 and indoleamine 2,3-dioxygenase (IDO) mRNA in the lesional and non-lesional oral mucosa of RAS patients and healthy individuals using real-time PCR assay. RESULTS Treg cells derived from RAS patients were less efficient in the suppression of cytokine production of CD4(+) T effector cells than Treg cells from healthy individuals. Moreover, in RAS, Treg cells were nearly twice less potent in the inhibition of CD4(+)CD25(-) T cell proliferation than in healthy donors. Furthermore, we have demonstrated the decreased proportion of CD4(+)CD25(+)FOXP3(+) Treg cells in peripheral blood of RAS patients compared with controls. We failed to detect FOXP3 mRNA, while IDO mRNA expression was decreased in non-lesional mucosa biopsies from RAS patients compared with ulcer biopsies or normal mucosa from healthy donors. CONCLUSIONS These findings suggest that CD4(+)CD25(high) Treg cells are both functionally and quantitatively compromised in RAS and that decreased constitutive expression of IDO in oral mucosa in RAS may lead to the loss of local immune tolerance.

Abstract
CD4+CD25+ T regulatory (Treg) cells play a central role in the suppression of immune response and prevention of autoimmune reactions. Pathogen recognition receptors expressed by immune cells, such as TLRs, may provide a critical link between the innate and adaptive immune systems. There is also evidence that TLR ligands can directly modulate the suppressive capacity of Treg cells. Here, we showed that CD4+CD25+ Treg cells affect neutrophil function and survival and that the TLR4 ligand is involved in the regulation of the cell interactions. We found that LPS-activated Treg cells inhibit reactive oxygen intermediates and cytokine production by neutrophils. Moreover, Treg cells reverse LPS-induced survival of neutrophils and promote their apoptosis and death. We also found that TCR-activated Treg cells induce the same effects on polymorphonuclear neutrophils as those achieved by TLR4 stimulation. Importantly, the suppressive potential of CD4+CD25+ Treg cells induced by LPS seems to be partially IL-10 and TGF-beta dependent, whereas anti-CD3/CD28 stimulation is rather contact dependent. Together, these observations suggest that Treg cells have the ability to directly regulate neutrophil function and life span when both types of the cells are exposed to LPS.

Abstract
Fish oils contain several active compounds that modify cell activity and influence various functions of the body. Shark liver oils are rich in alkylglycerols and squalene, but contain relatively low amounts of n-3 polyunsaturated fatty acids. Alkylglycerols may control immune response possibly throw modification of platelet activating factor (PAF) and diacylglycerol (DAG) production. Squalene enhances antigen presentation and induction of inflammatory response. Moreover, alkylglycerols and squalene have antitumour activity, that is possibly based on different mechanisms, ie., induction of apoptosis of neoplastic cells, suppression of signal transduction, inhibition of angiogenesis and promoting of transmembrane transport of cytotoxic agents. Shark liver oil has been found to be useful in treatment of conditions resulted from inadequate immune response, and in adjunctive treatment of several types of cancer.

Abstract
Recurrent aphthous ulcerations (RAU) are a chronic inflammatory disease with evidence of inappropriate immune response. Previous studies have suggested cell-mediated activation of immune response towards common micro-organisms of oral cavity in RAU. In this investigation, we explored cytokine production by peripheral blood mononuclear cells (PBMC) and T regulatory cell population in blood of active and remission RAU patients as crucial factors for maintenance of peripheral tolerance. Ten patients with minor RAU and 12 healthy individuals were selected for the study. Cytokine levels were analysed in supernatants using Cytometric Bead Array Kit for flow cytometry and ELISA. We have demonstrated increased production of Type 1 cytokines IL-2, IFN-gamma and TNF-alpha as well as IL-5, IL-6 and IL-8 by peripheral blood mononuclear cells in RAU. In contrast, IL-10 and TGF-beta anti-inflammatory cytokine production was decreased in RAU patients compared to healthy individuals. Moreover, we have found that CD4(+)CD25(+high) T regulatory cell proportion was decreased in RAU and represented 3.58+/-0.654% of CD4(+) T cells in active RAU, 4.66+/-0.561% of CD4(+) T cells in remission RAU, whereas in healthy controls CD4(+)CD25(+high) T cells represented 7.30+/-1.238% of CD4(+) T cells (p<0.001). Thus, the obtained results indicate that disproportion in cytokine production may be contributing factor in the pathogenesis of RAU. Alteration in the number of CD4(+)CD25(+high) T regulatory cells in RAU may additionally influence the development of the disease. We propose that imbalance in pro- and anti-inflammatory cytokine network may lead to the breakdown of peripheral tolerance in RAU and the excessive immune response towards harmless micro-organisms colonized oral mucosa or self-antigens.

Abstract
Fish oils supplementation has been recently widely used in prevention and treatment of the diseases in humans. Fish oil beneficial effects have been investigated in a number of animal disease models as well as human studies. Here, we examined clinical, immunological and biochemical effects of shark liver oil supplementation in high doses in 13 volunteers. The experiment was based on the consumption of 3.6 g of squalene, 3.6 g of alkylglycerols and 750 mg of n-3 polyunsaturated fatty acids (PUFA) per day for 4 weeks. We have shown the increased response of neutrophils towards bacteria, the increased level of C4 component of complement in blood, the rise of total antioxidant status of serum, and the predominance of Type I cytokine IFN-gamma, TNF-alpha and IL-2 production by peripheral blood mononuclear cells after shark liver oil intake. Moreover, shark liver oil supplementation markedly affect lipid metabolism and cholesterol balance. The increase of total cholesterol level from 182.92 +/- 29.290 mg/dl before oil consumption to 224.46 +/- 62.198 mg/dl after diet rich in oil, and the decrease of HDL fraction were noted. However, metabolism of lipids normalised spontaneously after the end of the experiment in all the individuals. The results of the present study have shown, that the main effects of shark liver oil are the result of the biological activity of squalene and 1-O-alkylglycerols, which dominate in the composition of the oil quantitatively. On the contrary, anti-inflammatory effects of n-3 PUFA do not manifest, when taking together with high doses of squalene and alkylglycerols. On the bases of these observations, we propose that shark liver oil supplementation in high doses is beneficial in bacterial, viral and fungal infections, whereas patients with atherosclerosis or autoimmune diseases should avoid the consumption of high amounts of shark liver oil.

Abstract
Naturally arising CD4+CD25+ T regulatory cells actively maintain immunological tolerance to self and non-self antigens. Treg cells inhibit proliferative response and cytokine production by effector cells, basically via cell-cell contact. Deficiency or dysfunction in these cells may result in autoimmune diseases. Treg cells may also influence the outcome of infection, cancer, transplantation, allergy, and even some forms of infertility. Enhancement or blockade of natural Treg cells may represent a therapeutic approach to many immunopathologies. However, Treg cells act like a 'double-edged sword', which is why all therapeutic manipulation of these cells on humans should be done with great caution.

Abstract
The intensity of neutrophil inflammatory response could be rapidly amplified by priming with pro-inflammatory mediators such as TNF-alpha, GM-CSF or LPS at low concentrations prior to stimuli. We proposed that epidermal growth factor (EGF) increases TNF-alpha-induced priming of human neutrophils. This study showed that EGF enhanced TNF-alpha-induced activation of neutrophils functions. The addition of EGF to neutrophils cultured with TNF-alpha resulted in increased respiratory burst and phagocytic activity of polymorphonuclear leukocytes (PMN) and up-regulation of adhesion molecule CD11b. Moreover, EGF enhanced IL-8 production by TNF-alpha-primed PMN. EGF alone was able to prime CD11b expression and IL-8 production by PMN. EGF receptor selective tyrosine kinase inhibitor, tyrphostin AG-1517, blocked the effect of priming with EGF, whereas the status of non-primed and TNF-alpha-primed neutrophils remained unaffected. EGFR expression on neutrophils was confirmed by flow cytometry and CELISA methods. These data provide the original evidence that EGF significantly enhances TNF-alpha-induced priming of human neutrophils acting through EGFR tyrosine kinase pathway. The observed effect may be a result of co-operative action of EGF, TNF-alpha and reactive oxygen intermediates (ROI).

Abstract
Understanding the role of immune system homeostatic balance is crucial for a better understanding of the pathogenesis of many diseases. The efficient regulation of immune response has been recently investigated in numerous studies that emphasize the important role of CD4+CD25+ regulatory T cells. These regulatory cells suppress the proliferation and cytokine secretion of effector cells directly via cell-cell contact and probably indirectly via TGF-beta. This makes T regulatory cells responsible for the control and suppression of inappropriate immune response to self antigens. Moreover, CD4+CD25+ regulatory T cells have an important function in the immunopathology of cancer, allotransplantion, and allergy. Based on murine and human studies, this review presents a characterization of the origin, phenotype, and function of CD4+CD25+ regulatory T cells. In addition, we show a hypothetical mode of the in vivo action of regulatory T cells, which play a central role in maintaining immune homeostasis.

Abstract
BACKGROUND Recurrent aphthous ulcers (RAU) is a chronic inflammatory disease with evidence of inappropriate immune response. This study presents the status of innate immune system in RAU. METHODS Twenty RAU patients and 19 healthy individuals were selected. The status of peripheral blood neutrophils (reactive oxygen intermediates (ROI) production, CD11b, TNF-RI and TNF-RII expression), concentration of antioxidants, sTNF-R, C3c, C4 and haemolytic activity of the complement system, as well as mannose-binding lectin (MBL), in the serum of RAU patients in active stage and in remission of the disease were determined. RESULTS Peripheral blood neutrophils were primed in RAU, which resulted in increased ROI production by resting and fMLP-stimulated neutrophils and diminished ROI production after in vitro priming. The increased expression of CD11b on resting and fMLP-stimulated neutrophils in RAU may also point to their previous in vivo stimulation. The decreased total antioxidant status of serum observed in RAU may be a result of increased ROI production by peripheral blood neutrophils. The levels of C3c, C4 and haemolytic activity of the complement system were higher in RAU than in healthy people. No significant differences between active and remission RAU were noted. CONCLUSION Presented observations confirm that the innate immune system is involved in RAU pathogenesis.
