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.

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.

New immunotherapy holds promise for ovarian cancerCAR 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.

Protein movement reveals brain tumour's weak spotProteins do not have a single shape, but are more like dynamic robots. But – how do they actually move? And what does this tell us about their function? Laura Orellana describes the movement of proteins using computer simulations – and has discovered a new drug target for glioblastoma brain tumours.

New method for detecting multiple cancers earlyWhen cancer is detected at an early stage, the rates of survival increase drastically, but today only a few cancer types are screened for. An international study led by researchers at Chalmers University of Technology and affiliated with Karolinska Institutet shows that a new, previously untested method can find multiple types of newly formed cancers at the same time – including cancer types that are difficult to detect with comparable methods. The results are published in the journal PNAS.

Women with a breast cancer diagnosis undergoing procedures for fertility preservation are not at increased risk of recurrence of the disease or disease-specific mortality. This has been shown in a study by Karolinska Institutet that followed the participants for five years on average. The results, published in the journal JAMA Oncology, could in the future provide safety and new hope to women who want to preserve their fertility after cancer treatment with chemotherapy.

Cool room temperature inhibited cancer growth in miceTurning down the thermostat seems to make it harder for cancer cells to grow, according to a study in mice by researchers at Karolinska Institutet. The study, published in the journal Nature, found that chilly temperatures activate heat-producing brown fat that consumes the sugars the tumors need to thrive. Similar metabolic mechanisms were found in a cancer patient exposed to a lowered room temperature.

Spider silk can stabilise cancer-suppressing proteinThe p53 protein protects our cells from cancer and is an interesting target for cancer treatments. The problem is, however, that it breaks down rapidly in the cell. Researchers at Karolinska Institutet have now found an unusual way of stabilising the protein and making it more potent. By adding a spider silk protein to p53, they show that it is possible to create a protein that is more stable and capable of killing cancer cells. The study is published in the journal Structure.

In a new study, researchers at Karolinska Institutet have identified the presence of a specific connection between a protein and an lncRNA molecule in liver cancer. By increasing the presence of the lncRNA molecule, the fat depots of the tumor cell decrease, which causes the division of tumor cells to cease, and they eventually die. The study, published in the journal Gut, contributes to increased knowledge that can add to a better diagnosis and future cancer treatments.
