Technique allows mapping of epigenetic information in single cells at scale

Technique allows mapping of epigenetic information in single cells at scale
Decoding epigenomic information from individual cells from the mouse brain. Histones are attached to DNA as beads on a string, with different versions decorating the genome as “epigenetic stickers”, labelling which genes are turned on or off. The method single-cell CUT&Tag allows to examine tens of thousands of single cells at the same time to determine their histone profiles. Illustration by Amagoia Agirre.
Histones are tiny proteins that bind to DNA and hold information that can help turn on or off individual genes. Researchers at Karolinska Institutet have developed a technique that makes it possible to examine how different versions of histones bind to the genome in tens of thousands of individual cells simultanously. The technique was applied to the mouse brain and can be used to study epigenetics at a single-cell level in other complex tissues. The study is published in Natu ....

Immune cells found in the brain are behind the depression experienced in inflammation

Special immune cells found in the brain, microglia, play a key role in the processes that make you feel uneasy and depressed in correlation with inflammation. This is the conclusion of a study using mice carried out by researchers at Linköping University, Sweden. The results have been published in the scientific journal
Immunity, and suggest that microglial cells contribute to the negative mood experienced during several neurological diseases, and maybe also depression.
David Engblom s research group at Linköping University has spent many years looking at why inflammation in the body, such as a common cold or influenza, causes us to feel poorly and despondent, and why we feel like retiring into our shell. The activity of the immune system influences nerve cells in some way. However, normal cells of the immune system are not able to get into the brain: it is sensitive and must be protected. Instead, the brain has its own spe ....
