Comparative Study on the In Vitro Cytotoxicity of Linear, Dendritic, and Hyperbranched Polylysine Analogues

Harm-Anton Klok, Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Zuzana Kadlecova

Lysine-based polycations are widely used as nonviral carriers for gene delivery. This manuscript reports the results of a comparative study on the in vitro cytotoxicity of a library of three structural polylysine variants, namely, linear polylysine (LPL), ...

Tumour-associated macrophages (TAMs) foster tumour progression by several mechanisms, including the promotion of angiogenesis, tissue remodelling, and immunosuppression. Such pro-tumoural activities are thought to be executed by TAM subtypes that harbour f ...

Notch1 mediates uterine stromal differentiation and is critical for complete decidualization in the mouse

Freddy Radtke

Uterine receptivity implies a dialogue between the hormonally primed maternal endometrium and the free-floating blastocyst. Endometrial stromal cells proliferate, avert apoptosis, and undergo decidualization in preparation for implantation; however, the mo ...

Background: Mass coral bleaching is increasing in scale and frequency across the world's coral reefs and is being driven primarily by increased levels of thermal stress arising from global warming. In order to understand the impacts of projected climate ch ...

Inflammasomes: current understanding and open questions

Andrea Ablasser

The innate immune system relies on its capability to detect invading microbes, tissue damage, or stress via evolutionarily conserved receptors. The nucleotide-binding domain leucine-rich repeat (NLR)-containing family of pattern recognition receptors inclu ...

Caspase-2-mediated cleavage of Mdm2 creates a p53-induced positive feedback loop

Etienne Meylan

Caspase-2 is an evolutionarily conserved caspase, yet its biological function and cleavage targets are poorly understood. Caspase-2 is activated by the p53 target gene product PIDD (also known as LRDD) in a complex called the Caspase-2-PIDDosome. We show t ...

It is All About Proteases: From Drug Delivery to In Vivo Imaging and Photomedicine

Hubert van den Bergh

Clinical studies provide overwhelming evidence for the importance of proteolytic imbalance and the upregulation of diverse protease classes in diseases such as cancer and arthritis. While the complex nature of proteolytic networks has hampered the developm ...

Listeria monocytogenes is sensed by the NLRP3 and AIM2 inflammasome

Andrea Ablasser

The inflammasome pathway functions to regulate caspase-1 activation in response to a broad range of stimuli. Caspase-1 activation is required for the maturation of the pivotal pro-inflammatory cytokines of the pro-IL-1beta family. In addition, caspase-1 ac ...

AIM2 recognizes cytosolic dsDNA and forms a caspase-1-activating inflammasome with ASC

Andrea Ablasser

The innate immune system senses nucleic acids by germline-encoded pattern recognition receptors. RNA is sensed by Toll-like receptor members TLR3, TLR7 and TLR8, or by the RNA helicases RIG-I (also known as DDX58) and MDA-5 (IFIH1). Little is known about s ...

Mechanisms of Apoptosis in Retinitis Pigmentosa

Mutations in humans are associated with several forms of inherited retinal dystrophies, such as Retinitis Pigmentosa which lead to retinal cell death and irreversible loss of vision. Genes involved in affected patients mainly encode proteins related to vis ...
