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

The cell is a multi-scale structure with modular organization across at least four orders of magnitude. Two central approaches for mapping this structure — protein fluorescent imaging and protein biophysical association — each generate extensive datasets, but of distinct qualities and resolutions that are typically treated separately. Here we present a computational framework to build a unified hierarchical map of human cell architecture...Read more

A bit more than two decades ago, the first Diablo game was released to the world. A game about a lone hero tasked with bringing down Diablo, one of the lords of Hell. This month we highlight a namesake to this hellish lord of terror, the protein DIABLO...Read more

The Cell Atlas database was just recently released with data on more than 12.000 proteins and mapping to 30 organelles. Today, the scientific findings are published in Science in "A subcellular map of the humanproteome".

The cell is a complex entity that carries out multiple functions. In order to do this, the different parts of the cells are organized in structures, called organelles. By investigating the organelles and its proteome, and to understand how the proteins vary over time and space we can truly begin to understand human biology on a detailed level...Read more

In 2017, February 28th will be the day that in Sweden is known as "Fettisdagen", (lit. "Fat Tuesday"), in other countries known as "Mardi Gras", "Faschingsdienstag" or "Shrove Tuesday". This day was originally celebrated in the Christian tradition as the last day of a three day feast to prepare for the forty day long fasting period before Easter. Today it has been popularized and in many places around the world this day is now known for its carnivals.

In Sweden together with some other northern European countries we like to eat "semlor" on Fat Tuesday...Read more
