Researchers at Karolinska Institutet in Sweden and Kyoto University in Japan have identified new subgroups of the blood cancer acute myeloid leukaemia. The study, published in the journal Nature, shows that changes in the regulation of genes within cells can help explain the variation in the disease and influence prognosis and treatment choices.

MedH researchers Christina Alexandrou and Marie Löf, together with their co-authors, have been awarded the Best Cited RCT 2023 prize by the highly regarded journal International Journal of Behavioral Nutrition and Physical Activity (IJBNPA).

A working group, commissioned by the Dean of KI Campus South, has developed a proposal for a joint and unified service organisation for the research environments in ANA Futura and Neo. The new organisation will be named Facility Management South (FM South) and is scheduled to be in place by 1 January 2027.

We congratulate researchers at MedH who have been awarded CIMED project grants for the period 2027-2029.

Facility management (FM) staff from KI's three research buildings: ANA Futura, Biomedicum and Neo gathered at Häringe Slott on 27–28 May for the first-ever joint FM conference. During the conference, it became increasingly clear that collaboration is the key to success.

On 11-13 May, safety inspections will be carried out in Neo. PIs and researchers are encouraged to participate.

An enzyme in the liver may partly explain sex differences in the body’s handling of cholesterol and the risk of developing atherosclerosis. This is shown in a new study from Karolinska Institutet, published in Nature Communications, based on experiments conducted in mice and human liver cells.

A genetic alteration that is already routinely analysed in patients with acute myeloid leukaemia can be used to identify patients who respond to a new targeted therapy, according to a study published in the journal Discover Oncology.

As a member of staff at KI, you play a vital role in preventing theft, vandalism and incidents that compromise safety on campus. Please follow the guidelines when receiving visitors at KI.

From January 1, 2026, there is a new arrangement for the safety courses in liquid nitrogen for Biomedicum, ANA Futura and Neo.

A new study demonstrates that the dietary fatty acid gamma-linolenic acid (GLA) derived from the mother's milk triggers a metabolic shift essential for heart cell maturation in newborn mice. Researchers at Karolinska Institutet contributed to the study published in Nature in May 2023.

While the relevance for human heart development still needs to be addressed, GLA is found in human breast milk and the GLA-activated nuclear receptors are highly conserved between mice and humans.

Immunotherapy has been shown to greatly improve survival rates for certain types of cancer. However, in some cases, it can lead to an over-activation of the immune system, which can be dangerous. In a recent review by researchers at Karolinska Institutet, potential therapies have been identified, which might make it possible to continue with immunotherapy even when facing severe side effects.
