Using EcoFab 2.0 devices and omics services at JGI, we will examine a plant growth promoting microbial community during interaction with different plant species.

The Great Rift Valley in Africa is a real treasure trove for discovering early human fossils. The fossils found in this part of Africa have determined our view of human evolution. But was the Great Rift Valley really the place where evolution took place or just a place where fossils are well preserved…

The vegetative growth period for leafy vegetables like lettuce is essential for yield and quality.

Bacteria often experience external challenges, such as changes in environmental conditions or attacks by bacteriophages.

This project investigates the rich linguistic history of the crucial language groups in East Africa and includes a search for words that indicate earlier lost languages. These outcomes, combined with recent archaeological and genetic research, will contribute to a new understanding of East Africa’s…

This research examines how right-wing extremist parents perceive and discuss their role in the ideological socialisation of their children.

What is the role of neuronal emotional reactivity in the intergenerational transmission of abuse?

In this thesis, the discovery and optimization is described of chemical tools to study the N-acylethanolamine (NAE) biosynthetic pathway.

The central aims of MicroClock project are to describe the B. subtilis circadian clock at molecular and functional levels, and discover the mechanisms of clock-regulated bidirectional signaling between B. subtilis and the model plant Arabidopsis

In this thesis, we used genetically engineered mouse models and a variety of cell-culture based assays to identify genes and pathways that are involved in the development and treatment of invasive lobular carcinoma (ILC).

This study offers a comprehensive but balanced grammatical analysis of Ik (Icetod), Northeast Uganda’s last thriving Kuliak language.

The article investigates the origins of Indo-European languages in Asia by 65 coupling ancient genomics to archaeology and linguistics.

This dissertation provides a description of Konso, a Cushitic language spoken by about 250,000 speakers in the South-West Ethiopia.

The company Azafaros was established in 2018 to translate innovative science from Leiden University and Amsterdam University Medical Center into novel disease-modifying treatment modalities for rare genetic metabolic disorders such as lysosomal storage diseases.

Uncover novel antimicrobials with prospective health benefits for sea turtles.

The Pharmacy research group focusses on the development of predictive models to improve clinical drug efficacy and safety. We work on clinical problems that require further mechanistic understanding and strive for ultimate benefit to patients.

Although plant domestication has significantly altered crop genetics and phenotypes, its effects on the taxonomic and functional diversity of plant-associated microbiomes are not well understood.

In the last decades, activity-based protein profiling (ABPP) has emerged as a powerful chemical tool that may aid the ever-challenging drug discovery process.

Does a moving hybrid zone leave a genomic footprint?

Microbial Sciences' contribution to the Bioactive Molecules research theme is to discover new bioactive molecules and enzymes and unravel their mechanisms of action, regulatory networks, and the (bio)synthetic pathways required for their production.

The research described in this thesis focused on identifying novel drug targets and synergistic combinations for triple-negative breast cancer (TNBC), a virulent subtype of breast cancer with a dismal prognosis and limited therapeutic options.

Atopic dermatitis (AD) is a common inflammatory skin disorder characterised by various epidermal alterations. Filaggrin (FLG) mutations are a major predisposing factor for AD and much research has been focused on the FLG protein.

Reconstructing language history and prehistory in the context of the Indo-European language family.

In Microbial Sciences, we perform multidisciplinary research to understand the structure and function of microbes at all levels of biological organization, from small molecules and cellular structures at atomic resolution to multicellular communities.
