This complex quadri-dimensional approach based on a clinical longitudinal MS population has not been considered in clinical terms before. The direct intestinal microbiome is ephemeral and highly influenced by alimentation, therefore, plasma SCFA analysis will eliminate the most frequent bias. The project will use a highly selective QTOF LC-MS system with a purpose-developed method in order to measure plasma SCFA levels. LC-MS is a modern technique increasingly used in recent years for biomonitoring and diagnostics.Project plan:Socio-demographical and clincal assessment of study population (20 RRMS, 20 SPMS, 20 benign MS, 20 naive MS, 20 controls);Harvesting of the plasma samples;SCFA analysis by HPLC (plasma): Development of detection of acetic, propionic, butyric and caproic acids and internal standard without and after derivatization, development of HPLC separation of the analytes, development of extraction method of the analytes from plasma, performance verification of the proposed analytical method: linearity, accuracy and precision;MMP and cytokine analysis by xMAP technology. Color-coded internally-dyed magnetic beads coated with specific monoclonal antibodies bind the analytes of interest in the biological sample. After unbound antigens are washed away, the previously formed antigen-antibody complexes are tagged with a fluorescent reporter via streptavidin\/avidin-biotin bridges. Analyte concentrations are determined by a 2-laser interrogation system: red laser for specificity identification based on each bead\u2019s internal dye, and green laser for quantification of bound analytes based on reporter fluorescence intensities. Patient samples with unknown concentrations are evaluated based on a calibration curve generated in the same analytical run;BDNF by ELISA method.<\/td><\/tr><tr><td>Project Start Date<\/td><td>01.04.2022<\/td><\/tr><tr><td>Project End Date<\/td><td>01.04.2024<\/td><\/tr><tr><td>Project Duration<\/td><td>24 months<\/td><\/tr><tr><td>Total Budget Value<\/td><td>50.000 EUR<\/td><\/tr><tr><td>Funding<\/td><td>Ministry of Research and Innovation, CNCS-UEFISCDI<\/td><\/tr><tr><td>Main Objectives<\/td><td><strong>Main Objective:<\/strong> To determine the influence that plasma SCFA have upon the peripheral immune processes (a selected cytokine pannel), BBB permeability (MMP), vagus nerve signalling and neuroprotection (BDNF) in different groups of MS patients (RRMS, SPMS, BMS, na\u00efve MS phenotype) treated with IFN\u03b2; Specific <strong>Objectives:<\/strong>(1) Development of detection of acetic, propionic, BA, CA and improve the internal standard of&nbsp; chromatography and mass spectrometry laboratory within the Centre for Advanced Medical and Pharmaceutical Research (CCAMF), without and after derivatization by high performance liquid chromatography (HPLC) in MS patients and HC;(2) To assess the impact of microbiota in clinical evolution of MS patients treated with IFN\u03b2;(3) To evaluate the dietary characteristics of the target population by personalised questionnaire;<\/td><\/tr><tr><td>Project Director<\/td><td>Laura-Iulia Barcutean<\/td><\/tr><tr><td>Project Mentor<\/td><td>Rodica Balasa<\/td><\/tr><tr><td>Results<\/td><td>The development of an effective method to evaluate plasma SCFA in MS patients using HPLC in order to discover if&nbsp; SCFA levels as biomarkers targeted for MS population can be used as biomarkers.<\/td><\/tr><tr><td>Host Institution<\/td><td>\u201eGeorge Emil Palade\u201d University of Medicine, Pharmacy, Science and Technology of Targu Mures<\/td><\/tr><\/tbody><\/table><\/figure>\n<\/div>\n<\/div>\n\n\n\n<p><br><strong>Results:<\/strong><\/p>\n\n\n\n<p>&nbsp;<strong>Achieved within 1\/2022 stage<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Coordination of a <strong>bachelor&#8217;s thesis<\/strong> of the student Manea Andrei, Faculty of General Medicine, entitled <strong>&#8222;Implications of nutrition in the evolution of patients with multiple sclerosis&#8221;,<\/strong> a thesis that was supported in the July 2022 Session, final grade 10 (Appendix 1).<\/li>\n\n\n\n<li>The organization of a special session entitled:<strong> &#8222;Microbiome alterations and implications in patients with multiple sclerosis \u2013 targeting neuroinflammation from the intestinal compartment&#8221;<\/strong>, within the first edition of the International Conference Toward Precision Medicine in Multiple Sclerosis Management, which took place in T\u00e2rgu Mure\u0219 during the 7 &#8211; October 8, 2022; with works presented in abstract indexed BDI, ISSN 2971-8171 (Appendix 2).<\/li>\n<\/ul>\n\n\n\n<p><strong>Laura B\u0103rcu\u021bean<\/strong> (Project manager): <em>Potential mechanisms of immune modulation targeting the intestinal microbiota.<\/em><\/p>\n\n\n\n<p><strong>Rodica B\u0103la\u0219a<\/strong> (mentor): <em>Gut-Brain axis: is MS a digestive triggered disease?<\/em><\/p>\n\n\n\n<p><strong>Achieved within 2\/2023 stage<\/strong><\/p>\n\n\n\n<p>Supporting a workshop with the theme: <strong>&#8222;Gut-Brain Axis.

Although the studies in this aspect have not established a clear connection for the pathogenesis of MS, it prompted <strong>the investigations in intestinal microbiota and the fermentation metabolites of the commensal bacteria<\/strong>. The gut bacteria ferment dietary fibers to produce <strong>short and medium fatty acids (SCFA\/MCFA).<\/strong> <strong>SCFA<\/strong> have demonstrated <strong>immunomodulatory properties<\/strong> and can transverse the blood-brain barrier and hypothetically exert their effects inside the central nervous system, by modulating inflammation and promoting neuroplasticity and remyelination. In the periphery, SCFA promote the differentiation of <strong>regulatory T lymphocytes<\/strong> and secretion of <strong>anti-inflammatory cytokines such as interleukin \u2013 10<\/strong>. <strong>MCFA, such as caproic acid<\/strong>, have contrasting, pro-inflammatory effects depending on the microbial pattern of the patients. Caproic acid promotes the immune differentiation toward a <strong>pro-inflammatory phenotype, Th1 and Th17<\/strong>, with secretion of proinflammatory cytokines. The selective permeability of the blood brain barrier ensures that immune cells have no way of passage into the brain parenchyma. In MS, the <strong>blood-brain barrier permeability is altered <\/strong>and inflammatory cells pass through, exerting the inflammatory cascade leading to demyelination, neurodegeneration and axonal loss. Matrix metalloproteinases (MMPs) are a set of enzymes involved in the maintenance and structure of the endothelial cells that compose the blood-brain barrier. MMP9 in particular has been linked with <strong>destructive effects<\/strong> on the blood-brain barrier and also the intestinal barrier.<\/p>\n\n\n\n<p>The gut brain axis represents a d<strong>ynamic communication between the intestinal tract and the central nervous system<\/strong>, functioning as a bidirectional signaling pathway through which the enteric system influences the brain and vice-versa. The central element of this ecosystem is represented by the intestinal microbiota. The direct connection between the intestinal compartment and the brain is partially <strong>mediated via the vagus nerve<\/strong>. One of the most important neuromodulators involved in this bi-directional communication is <strong>brain-derived neurotrophic factor (BDNF),<\/strong> which modulates the excitability of the vagal neurons. BDNF is also highly influenced by the SCFA, particularly butyric acid. The experimental approach of the intestinal microbiota is challenging due to the multitude of short-term influencing factors such as alcohol consumption, diet, treatment with pre\/pro biotics, stress, unhealthy diet, etc.<\/p>\n\n\n\n<p>Therefore, the present project proposed <strong>two important directions of research<\/strong>:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>The analysis of inflammation biomarkers from a quadri dimensional perspective (see schematic below)<\/strong>:\n<ul class=\"wp-block-list\">\n<li>Intestinal compartment: assessment of peripheral levels of SCFA\/MCFA<\/li>\n\n\n\n<li>Interaction between the gut and the brain via the vagus nerve: BDNF<\/li>\n\n\n\n<li>Pro and anti-inflammatory cytokines<\/li>\n\n\n\n<li>Integrity of the blood-brain barrier: MMP<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" width=\"217\" height=\"208\" src=\"https:\/\/umfst.ro\/wp-content\/uploads\/2024\/03\/2proiect.png\" alt=\"\" class=\"wp-image-23918\" srcset=\"https:\/\/umfst.ro\/wp-content\/uploads\/2024\/03\/2proiect.png 217w, https:\/\/umfst.ro\/wp-content\/uploads\/2024\/03\/2proiect-13x12.png 13w\" sizes=\"(max-width: 217px) 100vw, 217px\" \/><\/figure>\n\n\n\n<ol start=\"2\" class=\"wp-block-list\">\n<li><strong>Implementing and validating a working method by liquid chromatography-mass spectrometry<\/strong> (LC-MS\/MS) <strong>to assess SCFA and MCFA<\/strong> from serum samples<\/li>\n<\/ol>\n\n\n\n<p><strong>Concrete achievements<\/strong><\/p>\n\n\n\n<ol style=\"list-style-type:upper-roman\" class=\"wp-block-list\">\n<li><strong>Implementation and validation<\/strong> of a working method for LC-MS\/MS which allowed for the analysis of <strong>SCFA <\/strong>and<strong> MCFA<\/strong> from human serum, namely <strong>acetic acid, propionic acid, butyric acid and caproic acid<\/strong>, metabolites of the human microbiome with demonstrated immunomodulatory effects in MS.
