The remaining 90% is unexplained. Nevertheless, chronic hyperglycemia is the most important risk factor, e.g. for diabetic retinopathy. Recent research also shows that complications not only damage small vessels in the eye, kidney and nerve, but more or less all cells of an affected organ with varying proportions of individual cells in the total damage. The list of factors relevant to our understanding of pathogenesis and therapies based on it includes general mechanisms of glucose toxicity, protective factors against glycemic stress and cells or (sub)cellular components that are resistant to hyperglycemic damage. With a continued focus on the DIAMAP goals (a roadmap for diabetes research in Europe until 2020), the International Research Training Group 1874 \u201cDIAMICOM\u201d investigates these common mechanisms of early tissue damage, factors that mediate protection from damage, including those with beneficial or harmful memory function, and novel pathogenetically based therapies in four research areas (mechanisms &#8211; eye &#8211; kidney &#8211; nerve). The scientific projects are in line with the main objective of DIAMICOM, the joint training of excellent graduates from the fields of medicine and life sciences, in order to bridge the \u201cvalley of death\u201d of mutual lack of understanding of the respective research on the one hand, and to support the training of clinical researchers of the future on the other. Researchers at the University of Heidelberg (Mannheim and Heidelberg sites) have a good reputation in the field of experimental and clinical microangiopathy research and work in an excellent scientific environment, which is particularly supported by the establishment of the SFB 1118 (Reactive Metabolites as a Cause of Diabetic Complications; spokespersons P Nawroth and S Herzig). The partners in Groningen (UMCG) are internationally recognized for their excellence in experimental diabetology, vascular biology and pharmacotherapy. Both universities enjoy a long-standing collaboration in the field of joint graduate education with an established international MDPhD program. Sanofi as a partner supports the consortium in a very sustainable way through scientific and technological contributions, and supports graduate education with targeted contributions to individual project development and general career perspectives.

The MS-associated inflammatory response leads to a continuous degeneration of axons and neurons, resulting in progressive and permanent neurological disability of patients as the disease progresses. We have recently shown that the neuronal calcium-activated cation channel TRPM4 from the TRP cation channel family is activated by MS-associated inflammatory stimuli and plays a crucial role in the development of neurodegeneration. However, the role of other members of the TRP channel family with regard to protection or aggravation of neuronal cell death in inflammatory processes in the CNS is still completely unknown. Since many members of the TRP channel family act as sensitive sensor proteins for different environmental stimuli, we would like to identify those channel proteins that contribute directly or indirectly to the damage or protection of neurons by influencing immune responses or endothelial functions. Our preliminary work shows that the expression of TRPV4 is strongly upregulated in inflamed CNS tissue, and Tprv4-deficient mice show attenuated disease progression in the animal model of MS, experimental autoimmune encephalomyelitis (EAE). Part 1 of the work program will investigate how TRPV4 channel activity contributes to the pathogenesis of this disease in order to elucidate the key TRPV4 channel-mediated mechanisms of MS pathogenesis. In part 2 of the work program, our analysis will be extended to identify differentially expressed cation channels and their regulators in cells and tissues affected in the EAE model. By establishing new genome editing technologies in neuronal cells, in particular CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)-mediated recombination, it should be possible in the medium term to identify new regulators of neuronal calcium homeostasis in an unbiased experimental approach and to investigate them functionally with regard to neurodegeneration and neuroprotection. In summary, our proposal aims to identify the contribution of TRP channels and other regulators of neuronal calcium homeostasis to neurodegeneration in the CNS driven by inflammatory processes and to develop the basis for new neuroprotective therapeutic strategies for MS.<\/span><\/p><p><span style=\"color: #000000;\"><strong>Project in:: <\/strong><a style=\"color: #000000;\" href=\"https:\/\/gepris.dfg.de\/gepris\/projekt\/262890264\">FOR 2289:\u00a0 Kalzium-Hom\u00f6ostase bei Neuroinflammation und -degeneration: Neue Ansatzpunkte f\u00fcr die Therapie der multiplen Sklerose?<\/a><br \/><\/span><span style=\"color: #000000;\"><strong>Project Lead: <\/strong><a style=\"color: #000000;\" href=\"https:\/\/gepris.dfg.de\/gepris\/person\/1773715\">Professor Dr. Marc Freichel<\/a>;\u00a0<a style=\"color: #000000;\" href=\"https:\/\/gepris.dfg.de\/gepris\/person\/1818733\">Professor Dr. Manuel A.

Recently, several membrane proteins were identified in primary mast cell models that regulate Ca<sup>2+<\/sup> entry either as ion conducting constituents (e.g. Orai1), as direct activators of Ca<sup>2+<\/sup> entry channels (e.g. Stim1) or by functional agonism\/antagonism (e.g. SK4, TRPM4). However, numerous additional proteins including members of the TRPC family of cation channels, that are able to build or regulate Ca<sup>2+<\/sup> conducting channels, were identified in mast cells. Despite an extensive search for TRP channel modulators, studies to unravel their function and activation mode in primary cells and on organismic level still rely on experiments using transgenic animals in most cases due to the lack of agonists or antagonists with sufficient potency and specificity. We aim to define new and to refine known communication pathways contributing to agonist-induced [Ca<sup>2+<\/sup>]<sub>i<\/sub> rise in peritoneal mast cells (PMCs) as a model for mature connective tissue mast cells which differ in many aspects including their Ca<sup>2+<\/sup> signals from other mast cell models. We conduct a systematic expression analysis of genes encoding TRP channels and structurally and functionally related membrane proteins in PMCs. We have identified four TRPC proteins as important regulators of Ca<sup>2+<\/sup> signaling induced by Fc\u03b5RI-stimulation and Endothelin-1 and aim to identify the underlying channel, the mechanisms by which it regulates Ca<sup>2+<\/sup> entry and its relevance for mast cell functions.<\/span><\/p><p><span style=\"color: #000000;\"><strong>Project in: <\/strong><a style=\"color: #000000;\" href=\"https:\/\/gepris.dfg.de\/gepris\/projekt\/73031410\">SPP 1394:\u00a0 Mast-cells &#8211; promoters of health and modulators of disease<\/a><\/span><br \/><span style=\"color: #000000;\"><strong>Project Lead: <\/strong><a style=\"color: #000000;\" href=\"https:\/\/gepris.dfg.de\/gepris\/person\/1773715\">Professor Dr. Marc Freichel<\/a><\/span><br \/><span style=\"color: #000000;\"><em>Deutsche Forschungsgemeinschaft (DFG) &#8211; Projektnummer 124742924<\/em><\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-10d0b93 e-flex e-con-boxed wpr-particle-no wpr-jarallax-no wpr-parallax-no wpr-sticky-section-no e-con e-parent\" data-id=\"10d0b93\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-002d31f exad-sticky-section-no exad-glass-effect-no elementor-widget elementor-widget-spacer\" data-id=\"002d31f\" data-element_type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-ab9bfb6 e-flex e-con-boxed wpr-particle-no wpr-jarallax-no wpr-parallax-no wpr-sticky-section-no e-con e-parent\" data-id=\"ab9bfb6\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-6833b1b e-con-full e-flex wpr-particle-no wpr-jarallax-no wpr-parallax-no wpr-sticky-section-no e-con e-child\" data-id=\"6833b1b\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-4cad4f1 exad-sticky-section-no exad-glass-effect-no elementor-widget elementor-widget-heading\" data-id=\"4cad4f1\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">8)<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-9c6ad17 e-con-full e-flex wpr-particle-no wpr-jarallax-no wpr-parallax-no wpr-sticky-section-no e-con e-child\" data-id=\"9c6ad17\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-70daff4 elementor-widget__width-initial exad-sticky-section-no exad-glass-effect-no elementor-widget elementor-widget-heading\" data-id=\"70daff4\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">The role of TRP channels in cardiac remodeling (2007 \u2013 2015) (Clinical research group (Klinische Forschungsgruppe) 196)<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-ec21ee0 e-con-full e-flex wpr-particle-no wpr-jarallax-no wpr-parallax-no wpr-sticky-section-no e-con e-child\" data-id=\"ec21ee0\" data-element_type=\"container\">\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-cf42614 e-con-full e-flex wpr-particle-no wpr-jarallax-no wpr-parallax-no wpr-sticky-section-no e-con e-child\" data-id=\"cf42614\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-5428aa3 exad-sticky-section-no exad-glass-effect-no elementor-widget elementor-widget-text-editor\" data-id=\"5428aa3\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"color: #000000;\">TRP cation channels open after stimulation of Gq\/11-coupled receptors (e.g. AT1, ETA and \u03b11 receptors) and activation of phospholipase C. In the heart, these channels could trigger sustained Ca<sup>2+<\/sup> signaling and thereby signaling pathways involving CaM kinase, protein kinase C and calcineurin, leading to hypertrophy and insufficiency or tachyarrhythmias. To verify this possible involvement of TRP channels, we will <em>1)<\/em> identify individual TRPs in cardiomyocytes; <em>2)<\/em> analyze TRP-induced Ca<sup>2+<\/sup> signals and currents in cardiomyocytes;<em> 3)<\/em> characterize TRPC-deficient mice with respect to cardiac function compared to wild-type animals; <em>4) <\/em>identify TRPM4- or TRPM5-deficient mice in comparison to wild-type animals in terms of cardiac rhythmicity under \u201cnormal\u201d and Ca<sup>2+<\/sup> overload conditions and 5) try to transfer the results obtained in 1) to 4) to human heart tissue. Our hypotheses are that TRPC and TRPM4 channels are involved in the pathogenesis of cardiac hypertrophy and tachyarrhythmias, respectively, and represent targets of new drug strategies for these diseases. We have produced a large proportion of the TRP-deficient mouse animal models relevant for the proposed investigations in Homburg; others are available within the framework of collaborations.

We expect groundbreaking insights from studies on subcellular localization. We use the insights from the observed phenotype of the TMEM-deficient mice as well as from the properties of the structurally similar TRPML proteins, the mucolipins, which form cation channels in the plasma membrane and in intracellular organelles. Project in: SFB 894:\u00a0 Ca2+-Signale: Molekulare Mechanismen und Integrative FunktionenProject lead: Professor Dr. Marc FreichelDeutsche Forschungsgemeinschaft (DFG) &#8211; Projektnummer 157660137 4) Deletion and functional analysis of calcium channels in mice. (A 06) (2002 \u2013 2011 \u2013 Collaborative Research Center 530) With the help of transgenic mouse models, we investigate the biological functions of TRP proteins as subunits of cation channels that are activated by extracellular agonists or intracellular signaling molecules. The focus of the project will be to identify the roles of TRPV6 for male fertility and of TRPCs, TRPM3, TRPM4 and TRPM7 for Ca2+ influx into vascular smooth muscle cells, vascular contractility and blood pressure regulation as well as for platelet functions.

The remaining 90% is unexplained. Nevertheless, chronic hyperglycemia is the most important risk factor, e.g. for diabetic retinopathy. Recent research also shows that complications not only damage small vessels in the eye, kidney and nerve, but more or less all cells of an affected organ with varying proportions of individual cells in the total damage. The list of factors relevant to our understanding of pathogenesis and therapies based on it includes general mechanisms of glucose toxicity, protective factors against glycemic stress and cells or (sub)cellular components that are resistant to hyperglycemic damage. With a continued focus on the DIAMAP goals (a roadmap for diabetes research in Europe until 2020), the International Research Training Group 1874 \u201cDIAMICOM\u201d investigates these common mechanisms of early tissue damage, factors that mediate protection from damage, including those with beneficial or harmful memory function, and novel pathogenetically based therapies in four research areas (mechanisms &#8211; eye &#8211; kidney &#8211; nerve). The scientific projects are in line with the main objective of DIAMICOM, the joint training of excellent graduates from the fields of medicine and life sciences, in order to bridge the \u201cvalley of death\u201d of mutual lack of understanding of the respective research on the one hand, and to support the training of clinical researchers of the future on the other. Researchers at the University of Heidelberg (Mannheim and Heidelberg sites) have a good reputation in the field of experimental and clinical microangiopathy research and work in an excellent scientific environment, which is particularly supported by the establishment of the SFB 1118 (Reactive Metabolites as a Cause of Diabetic Complications; spokespersons P Nawroth and S Herzig). The partners in Groningen (UMCG) are internationally recognized for their excellence in experimental diabetology, vascular biology and pharmacotherapy. Both universities enjoy a long-standing collaboration in the field of joint graduate education with an established international MDPhD program. Sanofi as a partner supports the consortium in a very sustainable way through scientific and technological contributions, and supports graduate education with targeted contributions to individual project development and general career perspectives. Overall, DIAMICOM combines scientific excellence in microangiopathy research with a unique coeducational model of graduate education that includes important aspects of the private sector.
