AP News: The Big Question: Will cancer immunotherapy work for me? September 2017

SAN DIEGO (AP) — Dennis Lyon was a genetic train wreck. Cancer was ravaging his liver, lungs, bones and brain, and tests showed so many tumor mutations that drugs targeting one or two wouldn’t do much good. It seemed like very bad news, yet his doctors were encouraged. [Read More]

GEN News:  Lights, Camera, T-Cell Tentacle Action! May 2017

“All right, Dr. Krummel, I'm ready for my close-up." That’s what the T cell might have said to the director of a video project focused on microvillar dynamics. As you would guess from the word “dynamics,” the T cell isn’t playing the everyman or romantic lead. It’s more of an action hero, sensing danger, leaping into action, and ultimately besting microscopic villains. [Read More]

NY Times:  Immune System, Unleashed by Cancer Therapies, Can Attack Organs. Dec 2016

As Chuck Peal lay in a Waterbury, Conn., emergency room one Sunday in early September, doctors furiously tried to make sense of his symptoms. Mr. Peal, 61, appeared to be dying, and they were not sure why.

He slipped in and out of consciousness, his blood pressure plummeted, his potassium levels soared and his blood sugar spiked to 10 times the normal level. A doctor suspected a heart attack, but uncertainty left him urgently researching the situation on his phone [Read More]

NY Times:   Harnessing the Immune Response to Fight Cancer. July 2016

Steve Cara expected to sail through the routine medical tests required to increase his life insurance in October 2014. But the results were devastating. He had lung cancer, at age 53. It had begun to spread, and doctors told him it was inoperable.

A few years ago, they would have suggested chemotherapy. Instead, his oncologist, Dr. Matthew D. Hellmann of Memorial Sloan Kettering Cancer Center in New York, recommended an experimental treatment: immunotherapy. Rather than attacking the cancer directly, as chemo does, immunotherapy tries to rally the patient’s own immune system to fight the disease. [Read More]

Video Imaging Reveals How Immune Cells Sense Danger.  May 2017

How do T cells, the beat cops of the immune system, detect signs of disease without the benefit of eyes? Like most cells, they explore their surroundings through direct physical contact, but how T cells feel out intruders rapidly and reliably enough to nip infections and other threats in the bud has remained a mystery to researchers.

Surprising New Role for Lungs: Making Blood.  March 2017

Using video microscopy in the living mouse lung, UC San Francisco scientists have revealed that the lungs play a previously unrecognized role in blood production. As reported online March 22, 2017, in Nature, the researchers found that the lungs produced more than half of the platelets – blood components required for the clotting that stanches bleeding – in the mouse circulation. [Read More]

New ‘Immunoprofiler’ Initiative will Advance Drug Discovery, Precision Immunotherapy for Cancer.  January 2017

UC San Francisco scientists have formed an innovative research alliance with three global pharmaceutical companies to improve patients’ responses to cancer immunotherapy and to increase the effectiveness of immunotherapy across a wider range of cancer types. In 20 percent to 40 percent of patients with certain cancers, immunotherapy can trigger dramatic remissions, but despite recent advances most patients do not experience these profound responses, and many do not respond at all. In some cases, autoimmune side effects may also result. The sources of these variations are, as yet, unknown. [Read More]

Go-Between Immune Cell is Key to Priming the Body’s Fight Against Cancer.   July 2016

Using advanced imaging technology that allowed them to spy on interactions among cells in the lymph nodes of living mice, a research team led by UCSF scientists has identified a cell that is a key player in mounting the immune system’s defense against cancer. The finding opens a new avenue for targeted treatments in the rapidly advancing field of cancer immunotherapy. [Read More]

UCSF Research Suggests New Model for Cancer Metastasis.  March 2016

Scientists at UC San Francisco have been able to directly observe, for the first time, how invasive cancer cells create a beachhead as they migrate to the lung in a mouse model of metastatic cancer. What they saw was utterly surprising: early “pioneer” cancer cells that lodge in the lung generally die, but first they shed zombie-like particles that move around on their own and get gobbled up by waves of immune cells. Many of these immune cells, as if infected by the cancer particles, then burrow into the lung tissue, opening up space for future cancer cells floating through the blood to settle down safely and form new metastatic colonies. [Read More]

First Look at Metastasis.   July 2016

FIRST EVIDENCE: UCSF scientists are shining new light on how cancer spreads. In this video, "pioneer" cancer cells turn a lung's immune cells into zombie drones that protect future invaders, helping cancerous colonies form in new tissue. [Facebook Video]

Killing Cancer Through the Immune System.   February 2014

One of the confounding characteristics of cancer has long been that the body’s usually active patrol against viruses tends to leave deadly cancer cells alone to fester, mutate and spread.

The immune system has this blind spot by design – an immune system that has an ability to attack itself leads to autoimmune diseases, so as protection, it screens out its own tissue. [Read More]

Immune Cells Cluster and Communicate 'Like Bees,' Researcher Says.   March 2013

The immune system’s T cells, while coordinating responses to diseases and vaccines, act like honey bees sharing information about the best honey sources, according to a new study by scientists at UC San Francisco.

“In the morning, each bee goes looking individually for a sugar source, then comes back to the hive and does a dance in front of the other bees describing the location of what it’s found, which helps the hive decide collectively where the best source is,” said senior scientist Matthew Krummel, PhD, a UCSF professor of pathology.

 New Imaging Advance Illuminates Immune Response in Breathing Lung.  December 2010

Fast-moving objects create blurry images in photography, and the same challenge exists when scientists observe cellular interactions within tissues constantly in motion, such as the breathing lung. In a recent UCSF-led study in mice, researchers developed a method to stabilize living lung tissue for imaging without disrupting the normal function of the organ. The method allowed the team to observe, for the first time, both the live interaction of living cells in the context of their environment and the unfolding of events in the immune response to lung injury.

The Iconoclast.    November 2016

In May 2001 a middle-aged woman named Sharon visited her oncologist for what she thought could be her final appointment. Two months earlier, Sharon had been diagnosed with metastatic melanoma, and her condition was already well beyond dire. Her liver was riddled with metastases, a massive tumor was slowly collapsing her left lung, and fluid was pooling in the pleural cavity of her chest. Doctors didn’t expect her to live more than a few weeks. [Read More]

California Weekly: Hiding in Plain Sight: A Scientist Trains the Immune System to Attack Cancer from Within.  April 2012

The early 1990s were a heady time for immunology. Researchers had identified a “commander” molecule that launches the body’s white blood cells, called T cells, into battle against invaders such as viruses or bacteria.

Soon scientists were finding other molecular signals that helped rally the T cell troops. Hopes were high that drugs could be developed to treat autoimmune diseases and a range of other illnesses. [Read More]
