Multiple scientist levels are available, with advertised salary bands spanning USD 116,450–247,000 depending on level.

The Rydén and Mejhert laboratory recruits a postdoctoral researcher to study how metabolism regulates inflammatory gene expression in human white adipocytes. Projects investigate glutamine metabolism, signalling interactions and chromatin regulation using cultured cells, genetic and pharmacological perturbations, immunoblotting, co-immunoprecipitation, CRISPR, microscopy and metabolic measurements. This is a full-time temporary position in Solna. Apply through Karolinska’s recruitment portal by 16 October 2026 with the requested academic and research documents.

Different brain cell types exhibit distinct metabolic signatures that link energy economy to cellular function. Astrocytes and neurons, for instance, diverge dramatically in their reliance on glycolysis versus oxidative phosphorylation, underscoring that metabolic fuel efficiency is not uniform across cell types. A key factor shaping this divergence is the structural organization of the mitochondrial respiratory chain into supercomplexes. Specifically, complexes I (CI) and III (CIII) form a CI–CIII supercomplex, but the degree of this assembly varies by cell type. In neurons, CI is predominant

Parvalbumin-positive GABAergic interneurons (PV-INs) provide inhibitory control of excitatory neuron activity, coordinate circuit function, and regulate behavior and cognition. PV-INs are uniquely susceptible to loss and dysfunction in traumatic brain injury (TBI) and epilepsy but the cause of this susceptibility is unknown. One hypothesis is that PV-INs use specialized metabolic systems to support their high-frequency action potential firing and that metabolic stress disrupts these systems, leading to their dysfunction and loss. Metabolism-based therapies can restore PV-IN function after inju

Little is known about the critical metabolic changes that neural cells have to undergo during development and how temporary shifts in this program can influence brain circuitries and behavior. Motivated by the identification of autism-associated mutations in SLC7A5, a transporter for metabolically essential large neutral amino acids (LNAAs), we utilized metabolomic profiling to investigate the metabolic states of the cerebral cortex across various developmental stages. Our findings reveal significant metabolic restructuring occurring in the forebrain throughout development, with specific group

Gut-derived signals regulate metabolism, appetite, and behaviors important for mental health. We have performed a large-scale multidimensional screen to identify gut hormones and nutrient-sensing mechanisms in the intestine that regulate metabolism and behavior in the fruit fly Drosophila. We identified several gut hormones that affect fecundity, stress responses, metabolism, feeding, and sleep behaviors, many of which seem to act sex-specifically. We show that in response to nutrient intake, the enteroendocrine cells (EECs) of the adult Drosophila midgut release hormones that act via inter-or

Did we eat spaghetti for lunch because we saw our colleague eat spaghetti? What drives a risk decision? How can our breakfast impact our decisions throughout the day? Research from different disciplines such as economics, psychology and neuroscience have attempted to investigate the motives and modulators of human decision making. Human decisions can be flexibly modulated by the different experiences we have in our daily lives, at the same time, bodily processes, such as metabolism can also impact economic behavior. These modulations can occur through our social networks, through the impact of

Alzheimer’s disease is the most common age-related neurodegenerative disorder. Familial forms of Alzheimer’s disease associated with the accumulation of a toxic form of amyloid-β (Aβ) peptides are linked to mitochondrial impairment. The coenzyme nicotinamide adenine dinucleotide (NAD+) is essential for both mitochondrial bioenergetics and nuclear DNA repair through NAD+-consuming poly (ADP-ribose) polymerases (PARPs). Here, we analysed the metabolomic changes in flies over-expressing Aβ and showed a decrease of metabolites associated with nicotinate and nicotinamide metabolism, which is critic

Coordinated activity across networks of neurons is a hallmark of both resting and active behavioral states in many species, including worms, flies, fish, mice and humans. These global patterns alter energy metabolism in the brain over seconds to hours, making oxygen consumption and glucose uptake widely used proxies of neural activity. However, whether changes in neural activity are causally related to changes in metabolic flux in intact circuits on the sub-second timescales associated with behavior, is unclear. Moreover, it is unclear whether differences between rest and action are associated

Biologists have recently come to appreciate that eukaryotic cells are home to a multiplicity of non-membrane bound compartments, many of which form and dissolve as needed for the cell to function. These dynamical “condensates” enable many central cellular functions – from ribosome assembly, to RNA regulation and storage, to signaling and metabolism. While it is clear that these compartments represent a type of separated phase, what controls their formation, how specific biological components are included or excluded, and how these structures influence physiological and biochemical processes re

To function properly, the nervous system consumes vast amounts of energy, which is mostly provided by carbohydrate metabolism. Neurons are very sensitive to changes in the extracellular fluid surrounding them, which necessitated shielding of the nervous system from fluctuating solute concentrations in circulation. This is achieved by the blood-brain barrier (BBB) that prevents paracellular diffusion of solutes into the nervous system. This in turn also means that all nutrients that are needed e.g. for sufficient energy supply need to be transported over the BBB. We use Drosophila as a model sy
