Our bodies harbor countless microbes—and so do our tumors, it turns out. Over the past 5 years, researchers have shown cancer tissue contains entire communities of bacteria and fungi. Now, it appears some of the bacteria may be cancer’s accomplices. In a paper in this week, a team led by Susan Bullman of the Fred Hutchinson Cancer Center reports that in oral and colorectal tumors, bacteria live inside cancer cells and boost their production of proteins known to suppress immune responses. The microbial interlopers may set off a chain reaction that prevents the immune system from killing cancerous cells, and they may also help cancer metastasize to other parts of the body.

The study doesn’t entirely clinch the case for a bacterial role in cancer, but it is very suggestive, says Laurence Zitvogel, a tumor immunologist at the Gustave Roussy Institute. “It shows that bacteria in colorectal and oral tumors can actively disturb the immune equilibrium,” she says.

Confirmation that microbes can cause tumors to grow or spread could open up new ways to make cancer treatment more effective, for instance by killing bacteria with antibiotics. And because each type of cancer appears to come with a unique microbiome, researchers are exploring whether microbes could be used as a diagnostic tool to detect cancer early in a blood sample.

Engineered immune cells, known as CAR T cells, have shown the world what personalized immunotherapies can do to fight blood cancers. Now, investigators have reported highly promising early results for CAR T therapy in a small set of patients with the autoimmune disease lupus. Penn Medicine CAR T pioneer Carl June, MD, and Daniel Baker, a doctoral student in Cell and Molecular Biology in the Perelman School of Medicine at the University of Pennsylvania, discuss this development in a commentary published today in Cell.

“We’ve always known that in principle, CAR T therapies could have broad applications, and it’s very encouraging to see early evidence that this promise is now being realized,” said June, who is the Richard W. Vague Professor in Immunotherapy in the department of Pathology and Laboratory Medicine at Penn Medicine and director of the Center for Cellular Immunotherapies at Penn’s Abramson Cancer Center.

T cells are among the immune system’s most powerful weapons. They can bind to, and kill, other cells they recognize as valid targets, including virus-infected cells. CAR T cells are T cells that have been redirected, through genetic engineering, to efficiently kill specifically defined .

Researchers at the University of Colorado Anschutz find that the overexpression of a gene improves learning and memory in Alzheimer’s.

Alzheimer’s disease is a disease that attacks the brain, causing a decline in mental ability that worsens over time. It is the most common form of dementia and accounts for 60 to 80 percent of dementia cases. There is no current cure for Alzheimer’s disease, but there are medications that can help ease the symptoms.

Dr. Campisi has been at the forefront of studying cellular senescence for decades, revealing the mysteries of these not-exactly-dead cells and their role in many diseases of aging. In this episode, she joins her colleague Gordon to discuss the characteristics and function of senescent cells, as well as promising interventions on the horizon. Judy also describes how to get lucky in science by being prepared to see the unexpected.
