The development of the cation channel channelrhodopsin-2 (ChR2) from Chlamydomonas reinhardtii by Prof. Ernst Bamberg and his colleagues and its application to light-induced modulation of neurons paved the way for the field of optogenetics.
Over time the light-gated cation channel channelrhodopsin-2 (ChR2) has become an indispensable tool in neuroscience. Based on the pioneering work on ChR2 new variants have emerged, differing in their spectrum of light absorption, their kinetic ...

The cellular identity of mature cells that are confined in a specialized genetic expression profile can be overcome by introducing just a few genes that encode for so-called reprogramming factors [1]. By means of this intervention, also known as reprogramming, the cells then become pluripotent and represent induced pluripotent stem cells (iPS cells) [1]. Nowadays, numerous new cell culture models have been established based on reprogramming protocols that yield iPS cells. Such cell culture models ...

Precise genome editing demands for homology-directed repair (HDR) by aiming to introduce a new double stranded DNA substituting for a homologous sequence but partially defect one. This substrate dependent reaction does compete with direct non-homologous end joining (NHEJ) of the double strand breaks. NHEJ is error-prone and is therefor mainly used for gene inactivation.
The rate of NHEJ is directly limiting the rate of HDR. For this reason HDR in vitro does occur on a very low level only and ...

A Cas nuclease such as Cas9 can introduce a DNA double strand break in a sequence target that is complementary to a 20-nt spacer sequence of its bound guide RNA (gRNA) when a protospacer adjacent motif (PAM) is present. The gRNA can be provided as duplex of spacer containing CRISPR RNA (crRNA) and trans-activating crRNA (tracrRNA). Or as a single gRNA (sgRNA) where crRNA and tracrRNA are fused by an artificial loop.
Hence a gRNA consists of the target-specific spacer and a constant part typically ...

The LITESEC-T3SS (Light-induced translocation of effectors through sequestration of endogenous components of the T3SS) system represents a novel, fast, specific, and reversible method to control protein secretion into eukaryotic cells, enabling various medicinal and biotechnological applications, such as targeted drug delivery for tumor therapy.

An improved method to perform cell-free protein synthesis (CFPS) assays or other fluorescent assays in the context of CFPS with very low reaction mix volumes. Various additional advantages allow to significantly reduce costs and time.

We present an extremely sensitive, reliable and fast novel Lysine deacetylase (KDAC) assay, which can be performed in a continuous format. This novel KDAC assay is based on Firefly luciferase harboring an acetylation on an essential active site lysine, incorporated by genetic code expansion.

We furthermore offer a bacterial selection system that can help engineer KDACs. The selection system uses a reporter enzyme inactivated by lysine modifications at an essential active site residue, thereby ...

myNK cells are a novel myeloid NK subpopulation showing a unique expression pattern with the promise to treat obesity-associated pathologies such as cancer and diabetes. They could be detected in several different tumor tissues and a selective targeting of the upregulated myeloid markers might open the door for immunotherapy as a treatment option of certain obesity-associated cancer entities, obesity and diabetes.

Biomarkers of ageing have long been sought after to help assess the biological age and general health status of individuals. Considerable efforts have been invested to identify such biomarkers, including physiologic readouts, metabolic parameters, glycomic profiles and others. Nevertheless, markers with strong predictive power have remained elusive.

Work in model organisms has identified several conserved signaling pathways that extend life span, such as reduced insulin/IGF signaling and ...

A computer-implemented method that allows calculating concentration ranges of components within complex networks of biochemical reactions.
