Potential of Multidimensional, Large-scale Biodatabases to Elucidate Coagulation and Platelet Pathways as an Approach towards Precision Medicine in T…
2019
Cardiovascular and especially thrombotic diseases remain a major cause of morbidity and mortality worldwide. In past years, significant improvements in understanding disease processes, risk assessment, and prediction of clinical outcome in the field of thrombosis and haemostasis have been made by using large-scale biodatabases. These important research resources enable a comprehensive research approach by integrating clinical, environmental, genomic, and molecular information. Cutting edge, high throughput technologies open new data dimensions for clinical large-scale investigations. Joining multiple information levels from several pathophysiological pathways in contrast to a single marker …
New therapeutic strategies for treatment of inflammatory bowel disease
2008
Although the precise etiology of inflammatory bowel disease (IBD) still remains unclear, considerable progress has been made in the identification of cytokine-mediated signaling pathways involved in the inflammatory process. Recent data have clearly shown that these pathways induce augmented intestinal T-cell activation and thus resistance to apoptosis, which is a central process in disease pathogenesis, as it impairs mucosal homeostasis. Therefore, novel therapeutic strategies aim at restoring activated effector T-cell susceptibility to apoptosis in the gut, based on a pathophysiological rationale. This development is best exemplified by the emergence of agents that target the TNF pathway,…
Modeling a complex disease: Multiple sclerosis—Update 2020
2021
Multiple sclerosis (MS) is a complex inflammatory disease of the central nervous system (CNS) with an unknown etiology. Thereby, MS is not a uniform disease but rather represents a spectrum of disorders, where each aspect needs to be modeled with specific requirements-for a systematic overview see our previous issue of this review (Kurschus, Wortge, & Waisman, 2011). However, there is broad consensus about the critical involvement of the immune system in the disease pathogenesis. To better understand how the immune system contributes to CNS autoimmunity, the model of experimental autoimmune encephalomyelitis (EAE) was developed. EAE can be induced in susceptible animals in many different wa…
Animal Models of Cardiovascular Disease
2009
The use of animal models to study cardiovascular disease has made a substantial contribution to increasing our understanding of disease pathogenesis, has led to the development of diagnostic techniques, and has made it possible to verify the effectiveness of different preventative and therapeutic approaches, whether pharmacological or interventional. The main limitations stem from differences between human and experimentally induced pathology, in terms of both genetic regulatory mechanisms and factors that influence cardiovascular function. The experimental models and preparations used in cardiovascular research include those based on isolated cells or tissues or structures immersed in orga…
Functional regulation of HIF-1α under normoxia--is there more than post-translational regulation?
2011
The hypoxia-inducible factor-1 (HIF-1) is an oxygen-regulated transcriptional activator playing a pivotal role in mammalian physiology and disease pathogenesis, e.g., HIF-1 is indispensable in a broad range of developmental stages in different tumors. Its post-translational regulation via PHDs under the influence of hypoxia is widely investigated and accepted. Different non-hypoxic stimuli such as lipopolysaccharides (LPS), thrombin, and angiotensin II (Ang II), have been proven to enhance HIF-1 levels through activation of regulative mechanisms distinct from protein stabilization. Some of these stimuli specifically regulate HIF-1α at the transcriptional, post-transcriptional, or translatio…
Nondietary therapies for celiac disease.
2012
Currently, the only available therapy for celiac disease is strict lifelong adherence to a gluten-free diet (GFD). Although safe and effective, the GFD is not ideal. It is frequently expensive, of limited nutritional value, and not readily available in many countries. Consequently, a need exists for novel, nondietary therapies for celiac disease. Based on the current understanding of celiac disease pathogenesis, several potential targets of therapeutic intervention exist. These novel strategies provide promise of alternative, adjunctive treatment options but also raise important questions regarding safety, efficacy, and monitoring of long-term treatment effect.

Objectives Human leukocyte antigen (HLA)-B27 (B27) is the strongest genetic factor associated with development of Ankylosing Spondylitis and other spondyloarthropathies (SpA), yet the role it plays in disease pathogenesis remains unclear. We investigated the expression of potentially pathogenic non-conventional heavy chain forms (NC) of B27 in synovial and intestinal tissues obtained from SpA patients. We also determined the presence of NC-B27 in joints, lymphoid and gastrointestinal tissue from B27 transgenic (TG1) rats with M.tuberculosis-induced SpA.
