Abstract: Inflammation is driven by the chemokine network, which is a validated therapeutic target. Traditional anti-chemokine therapies that target single chemokines or receptors fail in treating inflammation, as diseased tissue typically expresses multiple chemokines that interact polyvalently with their receptors, making the chemokine network highly robust to attack. Evolution and natural selection for over 250 million years has resulted in the creation of a diverse arsenal of anti-inflammatory salivary peptides in tick saliva. One class of small peptides in tick saliva suppress chemokine-driven inflammation by acting as “ligand traps” – binding and neutralizing multiple chemokines, and are called evasins. These peptides combat inflammation at the site of tick bite and enable them to suck blood for days to weeks. We have developed a biotechnology platform – Bug-to-Drug – that uses yeast surface display of tick peptides. This has allowed us to efficiently mine tick salivary transcriptomes for evasin-like peptide molecules that bind chemokines. We have identified 12 novel CC and 30 novel CXC-binding evasins that are potent inhibitors of chemokine signaling, and are working to develop them as therapeutics for inflammatory disease.

“Controlling Nucleic Acids by Light”

Sensory photoreceptors mediate sensation of incident light and enable diverse organisms to derive spatial and temporal environmental cues for vital adaptations of physiology, behavior and lifestyle. Sensory photoreceptors excel in the reversibility, noninvasiveness and spatiotemporal precision of the responses they elicit. For precisely these reasons, sensory photoreceptors have found frequent use as genetically encoded, light-gated actuators in optogenetics, that is, the control by light of cellular events. Within an analytic, top-down branch, the Möglich lab focuses on elucidating the structural, mechanistic and functional bases that underpin the action of sensory photoreceptors. In a synthetic, bottom-up branch, they seek to engineer novel photoreceptors with custom-tailored light-regulated function: on the one hand, engineered photoreceptors broaden the scope of optogenetics, and on the other hand, they provide a crucial touchstone for the mechanistic understanding of signal transduction processes.

Research Projects include: Light-regulated Histidine Kinases – Engineering, Light-regulated Histidine Kinases – Structure & Mechanism, Regulating Transcription and DNA Cleavage by Light, Mechanism of Light-Oxygen-Voltage Receptors, Optogenetic Control of Cyclic-Nucleotide Signaling

„Multilevel strain engineering in Yarrowia lipolytica for the production of fuels and chemicals”

o Synthetic Biology: The group is interested in using and developing new synthetic biology tools that allow us to precisely manipulate microbial cells in a reliable, predictable and standardized way. In particular, we are interested in those cutting edge techniques that permit a fine tuning of metabolic pathways.

o Metabolic Engineering: The manipulation and optimization of microbial metabolic pathways are the keys for biotechnology and a bio-based economy. The research group is highly interested in hacking metabolism using synthetic biology tools to create new properties and enhanced behaviors in microbial cells. The engineering strategies are not only designed to produce new high-value products or higher amount of pre-existing products but also to facilitate the downstream and upstream parts of the bioprocesses.

o Microbial biotechnology and Microbial communities: Microorganisms are important for both industrial bioprocesses and biomedicine (i.e. gut or skin microbiota). The lab is interesting in a wide array of organisms, from yeast (S. cerevisiea and Y. lipolytica), fungus (A. gossypii) and bacteria (E.coli and Acetobacter) to complex microbial consortia (human and industrial microbiota).

o Applications in Industrial biotechnology and biomedicine: As a summary the lab is interested in applying the engineered microorganisms using synthetic biology to the production of 1) high-value chemicals and fuels (biodiesel, lipid-derived compounds, food additives, etc) 2) biomaterials for biomedicine and environmental applications (bacterial cellulose) and 3) understanding microbiome and dysbiosis leading to diseases (skin microbiome, wound healing).

Dr. Geoff Baldwin

Imperial College London, UK

“An integrated workflow for synthetic biology: from parts to systems and the evolution of new function”.

Research work in the Baldwin lab focuses on the development of synthetic biology approaches to facilitate the engineering of new biological systems for real-world applications. To this end we have developed foundational tools, like our BASIC DNA assembly method, that transform our ability to rapidly prototype new biological designs. We are also developing enhanced methods for accurate metrology to better understand and model the relationship between input design and phenotypic response. These fundamental developments are being applied across a broad range of projects that address gene circuit design; RNA feedback control; in vivo directed evolution for the generation of new protein specificity and functionality; engineering protein nanocages as vectors for targeted drug delivery.”

„Using sequencing to scale-up the design of synthetic genetic circuits”

Synthetic genetic circuits are composed of many interconnected parts that must function together in concert to implement desired biological computations. Unfortunately, genetic parts often display unexpected changes in their performance due to contextual effects within a design or unintended interactions with the host cell. In this talk, I will demonstrate how we have been using sequencing technologies and mathematical modelling to tackle this problem. I will show how RNA-sequencing can be used to reveal the inner workings of large genetic circuits to understand why some designs fail, and show how DNA-sequencing can support the rapid exploration of billions of different genetic circuits to better understand critical design features. Such capabilities provide a more complete view of inner workings of genetic circuits as they function and will help improve our understanding of the rules governing the effective construction of larger and more complex biological systems.

“Synthetic and diverse – microbiology on duty in industry”

In our societies quest to mitigate greenhouse gas emissions and petroleum use, industrial microbiology plays a key-role for the provision of processes for fuel and chemical production from renewable resources. Clearly, the microorganism is in the center of the process and care should be taken for its choice. Industrial production conditions are generally very harsh for the microorganism. Nevertheless, the host cells should be very efficient, which opens a vast area of conflict for the industrial microbiologist. Synthetic biology and metabolic engineering provide optimal tools for the rational design of biocatalysts. However, biodiversity is a major resource which should be tapped first. Nature solved many problems, which we face in industrial context – be it natural stress resistance or efficiency of metabolic pathways. However, all too often the rich source of natural diversity is neglected in favor of “pet” or model organisms. I propose that the fastest and most reliable path to efficient and economically viable microbial production processes uses both – natural diversity and synthetic biology. This concept shall be exemplified with bacterial and yeast host systems for the production of 1,3-propanediol, or sugar alcohols, respectively.

Orthogonal, light-inducible protein expression platform in yeast Sacchararomyces cerevisiae

The project Cell2Fab (from cells to fabrication) aims at the generation of a novel cellular regulation system on the basis of circular yeast chromosomes (xYAC) thereby facilitating highly regulated production of small to large cohorts of proteins and peptides in the yeast Saccharomyces cerevisiae. Successfully generated xYACs will enable us to access new areas of synthetic biosystems as for example: production of complex protein machines consisting of several subunits like naturally occurring multi-protein complexes of technical interest, production of entirely novel complexes with technical application areas and metabolic engineering.

Our protein expression system consists of different parts. First part is the AssemblX cloning system that allows easy and fast cloning of multiple protein expression cassettes, artificial operons, and regulatory systems. Second part is a regulation system composed of artificial transcription factors and their corresponding promoters. Furthermore, we establish regulation systems that allow the light-inducible protein expression.Overall, our system is designed as an open and flexible platform that allows customer-oriented adjustments to ensure fast and adequate adaptation to the needs of future users.

Cell size and growth rate regulation of stochastic gene expression

Cells adopt their physiology globally in response to different growth conditions. This includes changes in cell division rate, cell size, and also in gene expression. These global physiological changes are expected to affect noise in gene expression in addition to average expression. Gene expression is inherently stochastic and the amount of noise in proteins depend on parameters of gene expression and cell division cycle. Here we use models of stochastic gene expression inside growing and dividing cells to study the effect of cell division rate and cell size on noise in gene expression. In the first part of my talk, I will talk about modelling work inspired by E Coli data on global regulation with division rate. In the second part of the talk, I discuss how the single moleucle RNA Fish data can be used to infer specific form of global regulation of gene expression by cell size in fission yeast.

The work I will talk about is not published by this recent review gives a good overview of the topic: http://www.sciencedirect.com/science/article/pii/S1369527415000636
