Evading the Immune System

November 18, 2014

Lynn Wang from Carry the One Radio The Science Podcast in San Francisco spoke with Dr. John Wherry about evading the immune system. "Although our immune system s amazing at what it does, there are comples cases where it fails us. Everyday, our bodies fight off hordes of bacteria and viruses that cause disease. When fighting cancer, our bodies even face thier own cells that have gone rogue.  However, certain pathogens and cancers manage to cicumvent our immune system."

How Immune Cells Become Cancer Hunters

November 13, 2014

News outlets across the U.S. and in the UK covered the story of an Abramson Cancer Center patient who participated in a Penn clinical trial in which his own immune cells were modified to target and attack his leukemia. Marshall Jensen, a 30-year-old musician, husband and father recently returned to his Utah hometown in remission after spending several months in Philadelphia receiving treatment. His cancer had come back several times previously despite chemotherapy drugs and bone marrow transplants. “’We were calling it our Hail Mary pass,’” he said of the Penn trial. 'It felt right. … We didn't know how we were going to get out there, what we were going to do, but it worked. By God's grace I was able to come back.” The Penn research team is led by Carl June, MD, and Jensen was treated by David Porter, MD, and Noelle Frey, MD.

Laser and Drones: June at Penn Medicine, in Photos

June 30, 2014

The University of Pennsylvania campus largely falls silent in the summer months, but Penn Medicine keeps on truckin'. In fact, the month of June featured two of my favorite photography assignments thus far: lasers and drones.

First up, we have E. John Wherry, PhD, director of the Institute for Immunology, and his Becton Dickenson LSR II flow cytometer. If you have no idea what that means, you're not alone — so Wherry was kind enough to explain it:

"This instrument allows us to assess up to 20 parameters simultaneously at a single cell level with an amazing rate of up to 20,000 cells/second," he wrote in an e-mail. "As a result we can perform detailed profiling of the function of immune cells in different disease states."

Long story short, it enables researchers to determine which therapies are working and why a given therapy is effective or ineffective. This ultimately helps us develop better therapies and determine which patients will respond to a given treatment.

On top of that, it looks really cool. Wherry popped the hood on it and let me take a few shots. You can see them — and Wherry — in the slideshow at the bottom of this post.

Outstanding New Investigator Award

June 19, 2014

IFI investigator, Daniel J. Powell Jr. Ph.D., has been selected by the Board of Directors from the American Society of Gene & Cell Therapy (ASGCT) for a 2014 Outstanding New Investigator Award. Dr. Powell was selected from a competitive field of nominations based upon his significant contributions to the field of gene and cell therapy. The award ceremony and presentation session was held during the 17 th Annual Meeting in Washington DC on May 23 rd , 2014, and was attended by thousands of meeting participants. Below is a summary from his award presentation:

The Powell Lab is developing innovative immunotherapy strategies built upon clinical observations and studies in basic T cell biology. Adoptive T cell therapy using naturally-occurring tumor infiltrating lymphocytes (TILs) or peripheral blood T cells genetically modified to express a chimeric antigen receptor (CAR) can mediate comprehensive cancer elimination in patients, provided that highly avid, tumor antigen-specific T cells with the ability to proliferate and persist after infusion can be identified. We recently overcame one obstacle to widespread TIL therapy by showing that naturally-occurring tumor-reactive T cells in various cancers can be identified by their cell surface expression of the TNFR superfamily receptor, CD137, demonstrating a role for CD137 in the immunobiology of cancer. To instill T cells with enhanced ability to persist after infusion, we recently applied CAR technology as a tool to test the impact of various costimulatory signals on human CAR T cell survival following antigen encounter in vivo, and discovered a functional role for CD27 in human T cell memory formation. We also devised a novel dual CAR T cell approach where the TCR signal is dissociated from costimulatory signals in two independent CARs of distinct antigen specificity, thus delivering tumor-focused activity while comparatively sparing normal healthy tissues expressing a low level of single antigen. Lastly, to develop widespread T cell therapy, we pioneered a universal immune receptor approach that is adaptable in antigen specificity, allowing for highly personalized T cell generation based upon the repertoire of antigens expressed by each individual’s cancer cells. These strategies build on the early success of adoptive immunotherapy by addressing significant hurdles to otherwise safe and effective T cell therapy.
