Using genome editing to inactivate a protein called PCSK9 effectively reduces cholesterol levels in rhesus macaques, the first demonstration of a clinically relevant reduction of gene expression in a large animal model using genome editing. This finding could lead to a possible new approach for treating heart disease patients who do not tolerate PCSK9 inhibitors—drugs that are commonly used to combat high cholesterol.

Emerging CAR-T immunotherapies leverage modified versions of patient’s T-cells to target and kill cancer cells. In a new study, published June 28 online in Cell Stem Cell, researchers at University of California San Diego School of Medicine and University of Minnesota report that similarly modified natural killer (NK) cells derived from human induced pluripotent stem cells (iPSCs) also displayed heightened activity against a mouse model of ovarian cancer.

Researchers from the University of Illinois at Chicago have identified a protein that is crucial for activating inflammation — both the good kind of inflammation that leads to healing wounds and fighting infection, as well as excessive inflammation where the immune system can damage tissues and organs. The protein — an ion channel that spans the membrane of immune cells — presents a new target for the development of drugs that can restrain overblown inflammatory responses.

Researchers at the University of Virginia School of Medicine have discovered that microglia, specialized immune cells in the brain, play a key role in clearing dead material after brain injury. The study, which will be published June 25 in the Journal of Experimental Medicine, reveals that microglia gobble up the remnants of injured neurons, which could prevent the damage from spreading to neighboring neurons and causing more extensive neurodegeneration.

Children with known skin, food and respiratory allergies should be screened for an emerging food allergy called eosinophilic esophagitis (EoE), a painful inflammation of the esophagus. Pediatric allergists who analyzed a very large group of children say that EoE is a later component of the “allergic march”-- in which many children successively develop a series of allergies.

Proteins commonly known as BRCA – short for BReast CAncer susceptibility gene– serve a critical role in cellular DNA repair, but when mutated they allow genetic errors to replicate, facilitating cancer development. If the BRCA repair system is disabled in cancer cells, the cells simply turn to backup repair mechanisms and adapt to alternative repair pathways, a survival mode that also underlies their ability to evade targeted drug therapies.

Nearly 80 million Americans – one out of every four people – are infected with human papillomavirus (HPV). And of those millions, more than 31,000 will be diagnosed with an HPV-related cancer this year. Despite those staggering figures and the availability of a vaccine to prevent the infections that cause these cancers, HPV vaccination remains low in the U.S. Case Comprehensive Cancer Center has partnered with 69 other National Cancer Institute (NCI)-designated cancer centers to issue a statement urging increased HPV vaccination and screening to eliminate HPV-related cancers, starting with cervical cancer.
