New research at Karolinska Institutet in Sweden suggests a link between psychosis and a genetic change that affects the brain s immune system. The study published in
Molecular Psychiatry may impact the development of modern medicines for bipolar disorder or schizophrenia.
Psychosis affects approximately 2-3 per cent of the population and is characterized by a change in the perception of reality, often with elements of hallucinations and paranoid reactions.
Most of the people affected are patients with schizophrenia, but people with bipolar disorder may also experience psychotic symptoms.
The antipsychotics available today often have insufficient efficacy, and for patients, their life situation can be difficult.

Researchers have mapped out the changes in metabolism that occur after a heart attack, publishing their findings today in the open-access
eLife journal.
Their study in mice reveals certain genes and metabolic processes that could aid or hinder recovery, and might be good targets for treatments to prevent damage after a heart attack. Although some studies have looked at how changes in individual body tissues underlie mechanisms of disease, the crosstalk between different tissues and their dysregulation has not been examined in heart attacks or other cardiovascular-related complications, explains first author Muhammad Arif, a PhD student at KTH Royal Institute of Technology, Stockholm, Sweden. In this study, we performed an integrated analysis of heart and other metabolically active tissues using a mouse model of heart attack and used systems biology approaches to get a systematic picture of the metabolic changes that occur.
