The team, led by Professor Ken-ichiro Seino of Hokkaido University’s Institute for Genetic Medicine, found that thymic epithelium cells derived from mouse induced pluripotent stem cells (iPSCs) can regulate immune response to skin grafts, extending their…
T cells play a huge role in our immune system's fight against modified cells in the body that can develop into cancer. Phagocytes and B cells identify changes in these cells and activate the T cells, which then start a full-blown program of destruction. This functions well in many cases – unless the cancer cells mutate and develop a kind of camouflage that let them escape the immune system…
Researchers at Cardiff University have discovered a new type of killer T-cell that offers hope of a “one-size-fits-all” cancer therapy. T-cell therapies for cancer - where immune cells are removed, modified and returned to the patient’s blood to seek and destroy cancer cells - are the latest paradigm in cancer treatments. The most widely-used therapy, known as CAR-T, is personalised to each…

For many of us, a flu shot is a fall routine. Roll up a sleeve, take a needle to the upper arm and hope this year’s vaccine matches whichever viruses circulate through the winter. The most common method to make that vaccine is now more than 70 years old. It requires growing viruses in special, pathogen-free chicken eggs. It’s not a quick and easy manufacturing process. And, at best, it…
When immune cells invade the tumor, this is usually considered a good sign because the body's own immune system appears to be responding to the cancer. In the case of certain types of breast cancer immune cells, namely so-called tumor-infiltrating lymphocytes (TILs), these can determine survival rates and predict the usefulness of chemotherapy. This was shown by the largest meta study on TIL…
Genentech researchers have identified an enzyme that shifts pancreatic cancer cells to a more aggressive, drug-resistant state by epigenetically modifying the cells’ chromatin. The study, which will be published in the Journal of Cell Biology, suggests that targeting this enzyme could make pancreatic cancer cells more vulnerable to existing therapies that currently have only limited effect…
Determining where breast cancer ends and healthy tissue begins is a critical part of breast cancer surgery. Surgeons are used to working closely during surgery with anatomic pathologists who generate pathology reports that specify the surgical or tumor margin, an area of healthy tissue surrounding a tumor that also must be excised to ensure none of the tumor is left behind. This helps prevent the…

Any new build plan demands a low carbon footprint; respect for the environment is paramount. To capture all those elements, the plan to regenerate a previously 10…
Many tumors possess mechanisms to avoid destruction by the immune system. For instance, they misuse the natural “brakes” in the immune defense mechanism, which normally prevent an excessive immune response. Researchers at the University of Bonn have now been able to take off one of these brakes. The study, which involved colleagues from Hamburg and Würzburg, could pave the way for more…
Scientists drilling down to the molecular roots of Alzheimer’s disease have encountered a good news/bad news scenario. A major player is a gene called TREM2, mutations of which can substantially raise a person’s risk of the disease. The bad news is that in the early stages of the disease, high-risk TREM2 variants can hobble the immune system’s ability to protect the brain from amyloid beta,…
Combining a new compound with old drugs could provide an effective remedy against malaria and drug-resistant parasites.
Patients with unresectable, or inoperable, lung cancer are often given a dismal prognosis, with low rates of survival beyond a few years. Researchers exploring combination therapies have recently discovered improved survival rates by up to one year when patients treated with a newly formulated chemotherapy regimen are also given radiation therapy.
Every cancer is different and every patient is different. This insight gained in personalised medicine prompted oncology researchers to focus more on the individual patient’s immune system. It is particularly the immune system’s ability to destroy cancer cells that raised hope.

In a startling discovery that raises fundamental questions about human behavior, researchers at the University of Virginia School of Medicine have determined that the immune system directly affects – and even controls – creatures’ social behavior, such as their desire to interact with others. So could immune system problems contribute to an inability to have normal social interactions? The…
Pediatric laboratory medicine plays a minor role in the large field of laboratory medicine. This may be due to the low incidence of rare diseases, which are a major task of pediatric medicine, but also to the small number of pediatric samples in routine laboratory medicine overall. Since most diagnostic laboratories do receive pediatric samples now and then, it is essential that there are primary…
When a woman is diagnosed with the earliest stage of breast cancer, how aggressive should her treatment be? Will the non-invasive cancer become invasive? Or is it a slow-growing variety that will likely never be harmful? Researchers at the University of Michigan developed a new technology that can identify aggressive forms of ductal carcinoma in situ, or stage 0 breast cancer, from non-aggressive…
Researchers at Massachusetts Institute of Technology research center in Singapore have developed a new microfluidic device that tests the effects of electric fields on cancer cells.
