A new method, developed at Karolinska Institutet, KTH Royal Institute of Technology and SciLifeLab, can identify unique immune cell receptors and their location in tissue, a study published in the journal Science reports. The researchers predict that the method will improve the ability to identify which immune cells contribute to disease processes and open up opportunities to develop novel therapies for numerous diseases.
News
Researchers at Karolinska Institutet and the University of Oslo present a new type of immunotherapy that attacks cancer cells with a specific mutation. A study published in the journal Nature Cancer shows promising effects on patient cells in mice and offers hope for patients with acute myeloid leukaemia (AML), a cancer that has proven difficult to treat.

Maria Karvouni from the Center for Hematology and Regenerative Medicine (HERM) at the Department of Medicine, Huddinge (MedH) is defending her thesis: "Cellular and personalized therapies in Multiple Myeloma with special emphasis on retargeted NK cells" 16 June 2023. Main supervisor is Evren Alici (MedH).

Our skin contains specialised long-lived killer cells that protect against intruders. Researchers at Karolinska Institutet and the University of Copenhagen have now identified how these cells are formed, and shown that high levels of memory killer cells in cancer tissue correlate with a better survival rate in people with melanoma. The study is published in the journal Immunity.

Immunotherapy is an effective form of therapy for different types of cancer. However, for pancreatic cancer, its effect is limited and differs between men and women. Researchers at Karolinska Institutet have now found a possible explanation for this sex difference. The study, which is published in Cancer Research, reveals the presence of an immune cell in women with pancreatic cancer that obstructs the body’s immune response. The results can pave the way for a more sex-specific treatment.
News
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.
News
CAR T-cell therapy, a certain kind of cancer treatment in which the immune system’s T cells are programmed to attack tumour cells, is effective in mice with ovarian cancer, according to a study published in The Journal for ImmunoTherapy of Cancer. The researchers, who work at Karolinska Institutet, hope that the discovery will pave the way for a clinical trial to see how effective the treatment is for women with the disease.
News
Nano-sized membrane bubbles known as extracellular vesicles activate the immune system in mice and seem to render their tumours sensitive to a type of immunotherapy drug called a checkpoint inhibitor. This is according to a new study published in Cancer Immunology Research by researchers at Karolinska Institutet.
News
Researchers at Karolinska Institutet publish new findings in the journal Cancer Discovery showing how pharmacological activation of the protein p53 boosts the immune response against tumours. The results can be of significance to the development of new combination therapies that will give more cancer patients access to immunotherapy.
News
An international consortium that includes researchers at Karolinska Institutet has developed a ‘double antibody’ that targets two different sites of the SARS-CoV-2 virus, thereby preventing the virus from mutating to resist the therapy. A study published in the scientific journal Nature shows that the antibody potently neutralises SARS-CoV-2 and its variants and protects against COVID-19 in mice.
News
The blood is the main source of studies on the immune system, despite the fact that most diseases are combated by immune cells in the body’s tissues. A new study from Karolinska Institutet and the University of Pennsylvania has identified which immune cells patrol the human body’s tissues and circulate back into the blood. The study, which is published in Cell, shows that not all T cells do this – some are found mostly in the blood where they constitute a unique part of our immune system.
News
Immunotherapy for cancer has made great advances and many patients can now receive effective treatments that were not available ten years ago. However, there are certain types of cancer that do not respond to existing immunotherapy. A study from Karolinska Institutet in Sweden published in Proceedings of the National Academy of Sciences (PNAS) reports on a new kind of immunotherapy that gives hope of more treatment options for cancer in the future.
News
A new type of immunotherapy for the skin cancer malignant melanoma shows promising results. Three severely ill patients are now long-term survivors. The study, published in OncoImmunology, is the result of a collaboration between researchers at Karolinska Institutet and Karolinska University Hospital.
News
Three coronavirus projects coordinated by researchers at Karolinska Institutet have moved onto the grant negotiation phase in a bid for 9 million euros (95 million kronor) in EU funding. The projects aim to find a vaccine, immunotherapies and neutralizing antibodies against SARS-CoV-2 and are being coordinated by KI’s Matti Sällberg, Qiang Pan Hammarström and Benjamin Murrell.
News
Karolinska Institutet is granted funding from Vinnova to start a new centre of excellence. The centre will focus on developing next-generation immunotherapy based on NK-cells for the treatment of cancer.
News
Individuals with an inherited form of skin cancer often have a poor prognosis. The type of immunotherapy that was awarded this year’s Nobel Prize in Physiology or Medicine is, however, particularly effective in this patient group, research from Karolinska Institutet in Sweden shows. The study is published in the Journal of Medical Genetics.
News
Researchers at Karolinska Institutet have explored NK cell-based immunotherapy on patients with treatment-resistant leukaemia. The study, which is published in the scientific journal Clinical Cancer Research, shows that the new therapy is effective against several types of leukaemia.
