IGF1R regulates retrograde axonal transport of signalling endosomes in... EMBO Rep, 2020

Signalling endosomes are essential for trafficking of activated ligand–receptor complexes and their distal signalling, ultimately leading to neuronal survival. Although deficits in signalling endosome transport have been linked to neurodegeneration, our understanding of the mechanisms controlling this process remains incomplete. Here, we describe a new modulator of signalling endosome trafficking, the insulin‐like growth factor 1 receptor (IGF1R). We show that IGF1R inhibition increases the velocity of signalling endosomes in motor neuron axons,...

PRMT6-mediated H3R2me2a guides Aurora B to chromosome arms for proper... Nature Communications volume, 2020

Enjoy this exciting article by Kim et. al that was recently published in Nature Communications. The authors were finally able to show that H3R2me2a is the key histone mark for CPC recruitment onto mitotic chromosomes. Furthermore, results of this work support the interesting concept of arginine methylation as a dynamic process. Abstract The kinase Aurora B forms the chromosomal passenger complex (CPC) together with Borealin, INCENP, and Survivin to mediate chromosome condensation, the correction of erroneous spindle-kinetoch...

Variability in German Cockroach Extract Composition Greatly Impacts T... Front Immunol., 2019

What has a German cockroach to do with allergen-specific immunotherapy, you may ask? Well, read the following article by Birrueta et al. and find out …   Abstract German cockroach extract is used clinically to evaluate allergen-specific sensitization and for subcutaneous allergen-specific immunotherapy, though there are no guidelines for standardization in its manufacture. We performed an immunological evaluation of 12 different cockroach extracts prepared from different sources and their po...

Z-scan fluorescence profile deconvolution of cytosolic and membrane-as... Analytical Biochemistry, 2015

The Extracellular Matrix (ECM) is composed of collagen, non-collagenous glycoproteins and proteoglycans. These components are secreted from cells to create an ECM meshwork that surrounds cells and tissues. The ECM regulates many aspects of cellular function, including the cells' dynamic behavior, cytoskeletal organization and intercellular communication. Fibronectin and Laminin constitute the majority of the dynamic portion of the extracellular matrix of tissues and they are essential components of the culturing technique of many cell types. ...

NLRP3 inflammasome activation drives tau pathology Nature, 2019

The NLRP3 inflammasome links two major components of Alzheimer’s desease: amyloid-β and tau protein, as recently reported by scientists from German Center for Neurodegenerative Diseases (DZNE) and the University of Bonn. Amyloid-β plaques can activate the NLRP3 inflammasome which in return can result in additional amyloid-β deposits. On the other hand, NLRP3 inflammasome phosphorylates tau, resulting in tau aggregates within neurons. This ambilateral impact of NLRP3 inflammasome in the pathogenesis of tauopathies has been describe...

3 case studies: antibodies are valuable tools in clinical research Atlas Antibodies, October 2019

Applied biological or biomedical research aims to reach a thorough understanding of the physiology of organisms and to further development of disease therapeutics. Some scientific discoveries have narrow applicability or scope and are sometimes serendipitous or even entirely unexpected. Other have wider applicability and transferability having proved enormously useful over a wide range of domains. Among the latter are research antibodies. Read more to discover how they help progressing science. Secure the future of science by enabling the s...

Lipoic Acid Synergizes with Antineoplastic Drugs in Colorectal Cancer... Cells, 2019

Abstract Lipoic acid (LA) is a redox-active disulphide compound, which functions as a pivotal co-factor for mitochondrial oxidative decarboxylation. LA and chemical derivatives were shown to target mitochondria in cancer cells with altered energy metabolism, thereby inducing cell death. In this study, the impact of LA on the tumor suppressor protein p53 was analyzed in various colorectal cancer (CRC) cell lines, with a focus on the mechanisms driving p53 degradation. First, LA was demonstrated to trigger the depletion of both wildtype and...

Fragmented mitochondria released from microglia trigger A1 astrocytic... Nature Neuroscience 22, 2019

Efforts to reduce the personal and societal burden of neurodegenerative disease (ND) hinge on the identification of the underlying molecular mechanism(s) that causes neuronal death. One common aspect of neuronal death in Alzheimer’s disease (AD), amyotrophic lateral sclerosis (ALS), and Huntington’s disease (HD) is the relationship to the buildup of neurotoxic proteins. Glial cells, normally neuroprotective, can be transformed into a neuroinflammatory state (“A1” for astrocytes) stimulated by this neuronal detritus and by micro...
