Abstract:

Appetite control with relevance to immunometabolism has become critical to the treatment of non alcoholic fatty liver disease (NAFLD) and diabetes (1,2). Anti-aging genes (3,4) and their connections to autoimmune disease and mitophagy now identify the anti-aging gene Sirtuin 1 (Sirt 1) to be defective with increased heat shock proteins (HSP) involved in autoimmune disease and mitophagy (5) connected to irreversible programmed cell death in global populations. Appetite control or food restriction is required to maintain the heat shock gene Sirt 1 (6,7) that regulates HSP, amyloid beta and nitric oxide metabolism that are connected to natural killer cell activity, mitophagy and autoimmune disease in diabetes. Nutritional regulation of Sirt 1 with relevance to antimicrobial activity in humans (8) has become important to immunotherapy and the clinical treatment of NAFLD and diabetes. Nutritional diets that contain Sirt 1 activators have become vital to immunotherapy research to maintain immunometabolism and prevent mitophagy. Science and medicine and its relevance to genomic medicine (9) needs to consider Sirt 1 gene expression with its relevance to accelerated immune reactions that trigger acute cardiovascular disease. Various factors need to be considered as the trigger for toxic immune reactions with relevance to the progression of cardiovascular disease, NAFLD and diabetes.

Abstract:

Autoimmune hepatitis is a rare disease of low prevalence that is associated with diagnostic autoantibodies.  These autoantibodies are useful disease markers that facilitate the early diagnosis of autoimmune hepatitis for therapeutic intervention to prevent progression to liver cirrhosis and associated complications. Adult onset type 1 autoimmune hepatitis is associated with F-actin reactive smooth muscle SMA-T or SMA-G autoantibody, antinuclear autoantibody in 60% of patients, and autoantibody to SLA/LP in 15-20%. Juvenile onset type 2 autoimmune hepatitis is associated with LKM-1 and LC-1 autoantibodies. Liver autoantibodies in asymptomatic patients with normal liver function may precede the subsequent development of overt autoimmune liver disease. For routine diagnostic immunology laboratories, initial screening for smooth muscle SMA-T antibody by immunofluorescence remains the method of choice with confirmation for reactivity with F-actin by immunofluorescence.

Abstract:

Laboratory evaluations using established and emerging techniques in immunology are essential for the diagnosis and management of immune-mediated disorders. Inter-relationship between immunology and other laboratories such as chemistry, microbiology, and hematology now may overlap in diagnostic tests. Diagnosis of allergy, autoimmune disease serology, protein immunology including complement testing, cancer immunology, histocompatibility and immunogenetics, primary/secondary immunodeficiencies and infectious disease serology may now require analysis of a diagnositc protein that is critical for interpretation of global health and chronic disease. Sirtuin 1 analysis on blood, plasma and sera may be important to immunological tests with collection of plasma/sera sensitive to the appropriate preservative, freeze/thaw conditions and long term storage conditions. Bacterial lipopolysaccharides need to assayed on samples to avoid misinterpretations with relevance to Sirtuin 1 repression in immunological diseases.

Title: Role of T-cell in Bronchial Asthmatic
Speaker
Biography:

Abstract:

Background
Bronchial asthma is an inflammatory airway disease characterized by infiltration of inflammatory cells into bronchial tree and increased airway hyperreactivity to various physical and chemical stimuli.  T-cells play an important role in pathogenesis and inflammatory immune response in bronchial asthma.
The aim of this study was to detect soluble interleukin-2 receptors (sIL-2) serum levels, as marker of T lymphocyte activation in vivo, among bronchial asthmatic children.
Methods
The study was done at King Abdulaziz University Hospital from January 2015 to December 2015. 77 children were included and subdivided into three groups (acute asthmatic; chronic stable asthmatic and control (table 1, demographic data).  After History and clinical examination, with acute asthma were classified into atopic and non-atopic groups. Blood sample was taken from all groups and sIL-2R was measured by ELISA technique. 
Results
sIL-2R serum level was significantly elevated in acute and chronic asthmatic children versus controls (table 1). Meanwhile, in acute asthmatic, insignificant differences were recorded between different atopic states of the disease (table 2)
Conclusion
This study emphasize the role of T cells in asthma and suggest that regulation of their function may be important in the treatment of acute and stable asthmatic children as evident by elevated serum levels of sIL-2R.  Keywords: T cell; Bronchial asthma; soluble interleukin-2 receptors.

Biography:

Miss Reshma J. Nevagi is a PhD research scholar at faculty of science, University of Queensland (UQ), Australia. Prior to UQ, she pursued Master of Pharmacy (M. Pharm) from Pune University, India. Currently, she is working in vaccinology field with Prof. Istvan Toth and her research interest is to develop self-adjuvanting delivery systems for peptide-based vaccines. Her project involves interdisciplinary research including peptide synthesis, nanoparticles formulation, physicochemical characterization and immunological evaluation. Her aim is to do significant research contribution to develop prophylactic peptide vaccine for Group A streptococci (GAS) infection.

 

Abstract:

Statement of the Problem: Vaccination is cost-effective approach to enhance the host immunity against infections. Traditional vaccines comprised of live/attenuated or killed microorganism have been efficacious against many diseases such as influenza, small-pox, chicken-pox etc. However, pathogen-based vaccines may also be associated with risks of allergic responses. In recent years, new generation peptide-based vaccines have gained attention in vaccinology field, because of their safety profile and cost-effective production. Peptide-based vaccines utilize a small defined peptide fragment responsible for induction of immune responses which make them safer than other types of vaccines, but it also reduces its immunogenicity because of lack of danger signals. Hence, vaccine formulation into nano-complexes with the help of polymers enhances immunogenicity of peptide vaccines by improving entry and access into antigen-presenting cells. The purpose of this study is to develop a trimethyl-chitosan (TMC) polymer-based peptide nano-vaccine against Group A streptococcus (GAS) infection. Methodology: A peptide comprising of B-cell epitope from GAS M-protein (J8, QAEDKVKQSREAKKQVEKALKQLEDKVQ) and a universal T-helper cell epitope (PADRE, AKFVAAWTLKAAA) was conjugated to anionic polymer which then formed nano-complexes with TMC. J8-specific antibody titers were evaluated after intranasal administration of nano-complexes in C57BL/6 mice. The mice were challenged with M1 GAS strain 20 days after second boost and bacterial burden in nasal associated lymphoid tissue (NALT), throat swabs and nasal shedding was determined. Additionally, the opsonic activity of generated serum IgG antibodies was evaluated against various GAS strains. Findings: TMC-based nano-complexes were effective in generating high serum IgG and salivary IgA titers compared to negative control (PBS) mice group. Nano-complexes showed a reduction in bacterial load following intranasal M1 GAS challenge and also induced high opsonic IgG antibody titers. Conclusion: Developed vaccine delivery system based on TMC nano-complexes possessed adjuvanting properties and hence, it could be used to improve poor immunogenicity of peptide vaccines.

Abstract:

Background
Lagos rabies virus belongs to lyssavirus genus responsible for meningoencephalomyelitis in mammals that affect millions of people around the world and causes thousands of human deaths every year, to the best of our knowledge there is no peptide vaccine designed for Lagos rabies virus. The resulting peptide vaccine is expected to be more immunogenic and less allergic than conventional biochemical vaccines. The aim of this study was to design an Insilco peptide vaccine for Lagos rabies virus using Immunoinformatic tools.
Methods and Materials
Sequences of glycoprotein G of Lagos rabies virus was retrieved from NCBI, the retrieved sequences were then treated using different Immunoinformatic tools for B cell to find out the most conserved, surface and antigenic epitopes, and for T cell to find conserved peptides and to test their binding affinity to different MHC1 and MHC11 alleles. Then population coverage analysis and homology modeling was performed for most promising epitopes to show their structural positions in glycoprotein G.
Results and Conclusions
B cell tests were conducted for Bepipred with 22 conserved epitopes, Emini surface accessibility prediction with 12 conserved surface epitopes and Kolaskar and Tongaonkar antigenicity test with only three conserved epitopes being antigenic.
23 conserved epitopes were interacted with different MHC-1 alleles with (IC50) ≤500 while 39 conserved epitopes interacted with MHC-II alleles with IC50≤ 1000.
Among all the tested epitopes for world population coverage the epitope FVGYVTTTF binding to both MHC1 and MHC11 alleles was 97.30% and it was found to bind 13 different alleles that indicate strong potential to formulate peptide vaccine for Lagos rabies virus.

Abstract:

NADPH oxidase (NOX) activity has been suggested to be implicated in a plethora of cellular functions contributing to physiological and pathological conditions. Precise determination of NOX activity is not trivial. Several studies have addressed NOX activity in relation to polymorphisms in cis-acting genetic elements, however, providing much conflicting results. To date, no genetic polymorphism pertinent to one of the NOX subunits has been established as biomarker for NOX activity. We set up to determine activity of the phagocytic NOX by a particular sensitive assay in lymphoblastoid cell lines (LCLs) allowing iterative measurements on the same genetic background. A set of 290 LCLs of Caucasian origin with available genotypic data was split into training and test set by a 2:1 ratio. NOX activity determination was performed initially four times in each LCL at different days each with four same LCLs serving as reference for inter-day comparisons. Stringent criteria to identify outliers of the measurement series were applied to obtain a robust value of the NOX activity for each LCL. If these criteria were not met with at least three independent measurements two to four additional repetitions were conducted. If again applied stringent criteria fail robustness of repetitive NOX activity measurements the respective LCL was excluded from further analyses. Measurement series of LCLs which matched the consistency criteria elicited a mean variation coefficient of 17.0% (SD 10.6%). An almost identical distribution of the determined NOX activity was noted for the training and the test set of LCLs. These data prove our method suitable for reliable assessment of NOX activity providing a reliable basis for pending association testing with genotypes. As with 290 LCLs a total of 1500 NOX activity measurements, each time assayed in quadruplicates, were performed, this study is the largest conducted in this context so far.

She has presented at many conferences, including Days of Molecular Medicine in Karolinska, the International Conference on Autoimmunity in Porto, Portugal, the American Society of Hypertension Meeting, Enabling Future Pharma, Perspectives in Rheumatic Diseases, Immunology Summit, International Lyme Society, American Association of Family Practitioners and the 18th Vitamin D Workshop. She is the co-author of a chapter in the textbook Vitamin D: New Research and the lead author of the ground-breaking review article Inflammation and vitamin D: the infection connection published in the October 2014 issue of Inflammation Research.

Abstract:

Inflammation is believed to be a contributing factor in many chronic diseases. The influence of vitamin D deficiency on inflammation is being explored but studies have not demonstrated a causative effect. Low serum 25(OH)D is also found in healthy persons exposed to adequate sunlight. Despite increased vitamin D supplementation inflammatory diseases are increasing. The current method of determining vitamin D status may be at fault. The level of 25(OH)D doesn’t always reflect the level of 1,25(OH)2D. Assessment of both metabolites often reveals elevated 1,25(OH)2D, indicating abnormal vitamin D endocrine function. Some authorities now believe that low 25(OH)D is a consequence of chronic inflammation rather than the cause. Research points to a bacterial etiology pathogenesis for an inflammatory disease process which results in high 1,25(OH)2D and low 25(OH)D. Immunotherapy, directed at eradicating persistent intracellular pathogens, corrects dysregulated vitamin D metabolism and resolves inflammatory symptoms. This article reviews vitamin D’s influence on the immune system, examines the myths regarding vitamin D photosynthesis, discusses ways to accurately assess vitamin D status, describes the risks of supplementation, explains the effect of persistent infection on vitamin D metabolism and presents a novel immunotherapy which provides evidence of an infection connection to inflammation.

Title: The effect of surface glycans on leukemia susceptibility to NK-mediated cytotoxicity
Speaker
Biography:

Dr. Yuh-Ching Twu is Associate Professor at Department of Biotechnology and Laboratory Science in Medicine, National Yang-Ming University.  She received her BS and Master degree in Biotechnology & Laboratory Science from National Yang-Ming University, and PhD degree in Biochemistry Science from National Taiwan University.  Her post-doctoral programs were done in Department of Microbiology and Immunology, University of British Columbia and Terry Fox Laboratory, BC Cancer agency.  She works on the molecular genetics of human blood group I locus, the regulatory mechanism of branched I formation, and the correlation with immune-surveillance. 

 

Abstract:

The aberrant glycosylation on proteins and lipids has been implicated in malignant transformations through promoting the tumorigenesis, metastasis, and the evasion from the host immunity.  The I-branching β-1,6-N-acetylglucosaminyltransferase, responsible for the straight i conversion to branched I histo-blood group antigens, has been reported for its important effects on the migration, invasion, and metastasis of solid tumors.  First, we demonstrated that SHP-2-ERK2 signaling regulates the phosphorylation status of C/EBPa to by altering its binding affinity onto the IGnTC promoter region, thereby activating the synthesis of cell-surface I antigen formation during erythropoiesis.  Second, we addressed how the branched I antigens on the leukemia impacted the host immuno-surveillance mediated by natural killer (NK) cells.  The levels of I antigen presented on leukemia cells showed a positive correlation with the susceptibility to NK-mediated lysis.  Third, by the conjugation assay, elevating the expression of the I antigens on the leukemia cells that can only display low level of cell surface I antigens greatly increased the sensitivity to NK cytotoxicity.  Our findings suggested that branched I of the leukemia cells not only is important for NK targeting but also could serve as a potentially evaluation maker for NK-cell based leukemia treatment.

Abstract:

Probiotics are live microorganisms, which administered in adequate amounts, confer a health benefit on the host. Modulation of the immune response seems to be the common mechanism associated to the consumption of probiotics. Presumably, probiotics must establish a close relationship with dendritic cells (DCs), which are able to recognize microbial products by extending their dendrites to the intestinal lumen. Recent studies have shown that DCs activity can be modified following administration of probiotics, especially of the genera Lactobacillus and Bifidobacterium using in vitro methodology. In this sense, the analysis of the host-probiotic interaction represents a dynamic and complex process, which can be studied through tools based on the "omic" sciences. The aim of the present study is to analyze the expression of differential proteins of the interaction between probiotics isolated from breast milk and DCs using proteomics techniques, whereby DCs were generated from peripheral blood monocytes from four healthy participants and were co-cultured with probiotics of the genera Lactobacillus and Bifidobacterium previously isolated from breast milk. After 3 hours of co-cultivation under optimum conditions, the proteins were extracted from each culture, thus generating 2D proteomic maps (SDS –PAGE) and a differential proteomic expression was found derived from the interaction of the co-cultures compared to single cultures. To the moment, our results suggest that the activity of DCs can be successfully regulated by interaction with probiotics.
Key words: probiotics, breast milk, dendritic cells, proteomics.

Abstract:

Background
 Myofascial pain syndrome affects hundreds of millions of people worldwide resulting in higher medical costs due to limited treatment efficiency and the need for preventive measures.
Pathognomonic symptoms in myofascial pain are highly sensitive local myofascial nodules in skeletal muscles.
Despite numerous ongoing studies regarding etiopathogenesis and treatment of this disorder, it remains highly prevalent (up to 85% of population) pointing to further research.
Different medical specialists try to unravel a secret of myofascial pain that confirms the necessity for multidisciplinary approach to this problem.
Given the integrative role of central nervous system, its plasticity as the important property enabling adaptive holistic host responses in health and disease, it appears reasonable to  examine relationship between clinical-electroneurophysiological mechanisms of myofascial pain syndrome in correlation with cytokine expression profile. There are only few publications on cytokine expression in myofascial pain. They mostly deal with serum and muscle tissue cytokine profiles in athletes performing long-term physical activities.
Aim
To examine clinical and electroneurophysiological patterns in dynamic correlation with cytokine responses in patients with myofascial pain to further delineate pathogenetically based complex treatments including methods of complementary medicine (various acupuncture techniques, osteopathy, hirudotherapy, etc.).
Materials and methods
Subjects of the study are 54 patients with myofascial pain syndrome (aged 18-55, 34 females, 20 males) and 25 healthy controls matched for age and gender. The informed consent was obtained from all participants. We conduct comprehensive clinical and electroneurophysiological examination combined with quantitative real-time PCR cytokine profile expression (IL-1β, IL-8, IL-4, IL-10) in core needle muscle biopsies taken from highly sensitive myofascial nodules. Subjects had received advanced treatment involving different methods of osteopathy, acupuncture, hirudotherapy, antihomotoxic preparations.
Results
There is an increase in expression of proinflammatory cytokines IL-1β, IL-8 in untreated patients versus controls. Patients after treatment upregulate expression of anti-inflammatory cytokines IL-4, IL-10. Changes in cytokine expression correlate with biomarkers of brain polysynaptic reflex excitability.
Conclusions
Study of tissue cytokine expression in myofascial pain syndrome in correlation with regular clinical and neurophysiological biomarkers might serve for improving personalized diagnosis, choice of treatment modalities, prognosis and prevention.
