Katja Petzold has been awarded the Hugo Theorell Prize in biophysics 2022. The focus in her lab is to study structural changes in RNA – e.g. the RNA in the ribosome – and to develop methods for this purpose.

A new study shows how antibodies select the antigens that they bind to, as they navigate the surface of pathogens like coronaviruses. Researchers from KTH Royal Institute of Technology and Karolinska Institutet have created a model that suggests the migration of these pathogen hunters may be akin to the random movements of a child playing on stream laden with stepping stones.
News
Researchers at Karolinska Institutet have succeeded in mapping the neuron types comprising the enteric nervous system in the intestine of mice. The study, which is published today in the scientific journal Nature Neuroscience, also describes how the different neurons form during fetal development, a process that follows different principles to brain neurons.

While proteins on the surface of cells are the targets for most drugs, refined methods are needed to analyse how these membrane proteins are organised. Researchers at Karolinska Institutet have developed a new DNA-based analytical method that could contribute to the development of future drugs for breast and other cancers. The study is published in Nature Nanotechnology.
News
A study lead by KI researcher and SciLifeLab Fellow Simon Elsässer elucidates a new flavour of heterochromatin, used by embryonic stem cells to silence ‘parasitic’ DNA-elements within the context of their highly dynamic pluripotent chromatin. The study was recently published in Nature Communications.

Cell surface receptors are essential for the communication of human cells. Simon Elsässer’s lab has developed a method to study these proteins on living cells. With very subtle alterations the method allows to label receptors with two different fluorescent probes in defined positions, as the authors show in Cell Reports. This can give detailed insights in how the conformation of a receptor changes as a result of for example drug binding, in the natural setting of the cell membrane.
News
Research from Karolinska Institutet published today in Nature shows that an RNA molecule involved in preventing tumour formation can change its structure and thereby control protein production in the cell. The finding can have important clinical implications as it opens for new strategies to treat different types of cancer.

Arne Holmgren, Senior Professor at Karolinska Institutet, died on January 6, 2020, 79 years old. Dr. Holmgren was widely known as one of the groundbreaking scientists establishing the rapidly growing field of redox biology.
News
Researchers at Karolinska Institutet in Sweden have uncovered a chromosome-wide mechanism that keeps the gene expression of sex chromosomes in balance in our cells. The findings shed light on molecular reasons for early miscarriage and could be important for the emerging field of regenerative medicine. The study is published in Nature Structural and Molecular Biology.
