The brain is a high energy consuming tissue that needs a continuous supply of energy substrates from the circulation for optimal neurological function. Astrocytes are important for regulating the relationship between energy consumption and dynamic neuronal activity in the brain and are mainly involved in processes used for efficient transfer of energy substrates to neurons. Changes in astrocyte energy metabolism could therefore potentially disrupt essential neuronal processes, and this cell type has also been shown to undergo structural and biochemical changes in Alzheimer's disease (AD). Here the cell type distribution and cellular levels of the brain enzyme CKB, which is crucial for energy homeostasis and known to have decreased activity in AD, has been investigated to identify changes associated with neurodegenerative processes...Read more

Recombinant proteins are important resources in several stages of drug discovery as well as many other types of research. The amounts of pure protein required span from a few micrograms for immunisations to hundreds of milligrams or even grams for activity evaluations and structure determinations. Here a highly scalable process for protein production in CHO cells that generates robust product quality and high performance throughout scales is presented...Read more

A publication in Science presents the largest-ever dataset of neural connections, providing a glimpse into the brain's complexity. This seemingly tiny volume of one cubic millimeter contains the impressive number of 57.000 cells, 150 million synapses, and 230 millimeter blood vessels...Read more

Metastasis formation is a multistep process that involves cancer cell transmigration through tumor vessels and through the healthy vasculature of the affected organ. This process is limited by an intact vascular barrier formed by endothelial cells, ECM, and pericytes. In a publication in JCI Insight, researchers from HPA and Uppsala University studied the role of the protein CD93 in maintaining vascular integrity in metastatic cancers...Read more

Current approaches to determine molecular signatures of health often rely on samples taken by venous blood draws at health care centers. In a study published in Communications medicine, researchers from KTH, Karolinska Institute, and the University of Gothenburg instead used a home sampling device to collect dried blood spots from the general population during the COVID-19 pandemic...Read more
