Oncolytic Virus in Research May Herald a Cancer Vaccine for the Future

April 2, 2018 Chris 1 Comment

Immunotherapy brings breakthroughs to cancer treatment.

Promising new cancer treatment research by UC San Francisco has uncovered a cancer killing virus. The vaccine-like effect of the virus harbors potential for use with cancer immunotherapy treatment options, killing some cancer cells directly, and prompting a widespread immune system response to cancer cells far beyond the region the virus infects.

Tremendous Potential
Bringing surprising insight, this new research digs deeper into how oncolytic (cancer-killing) viruses can cooperate with the immune system in attacking cancer cells and tumors. Currently in clinical trials, it points to opportunities in the realm of immunotherapy combination therapies – therapies specifically devised to unleash the full cancer fighting potential of the immune system.

Researchers likened such oncolytic viruses as the equivalent of a bomb, jarring the immune system into action and resuscitating the immune response.

How Do They Work?
Researchers are still coming to terms with fundamentals, which seem to indicate cancer killing viruses attack cancer cells in a number of different ways:

-Through direct infection.
-Via the release of tumor-specific proteins, which trigger a widespread immune response to cancer cells.
-By destroying the blood supply tumors required to survive.

Why a Virus?
Cancer researchers have been exploring the idea of oncolytic viruses since the early 20^th century, after observing dramatic remissions following some viral infections. They’ve been actively developing these viruses since the 1980s. With the FDA’s approval and release of oncolytic viral therapy Imlygic (T-Vec) in 2015, such treatment modalities are quickly coming to the forefront of up-and-coming therapy options.

Research Studies Now Under Way to Starve Cancer Tumors

March 30, 2018 Chris 2 Comments

According to a popular old wives’ tale, you should starve a cold and feed a fever. Scientists working on immunotherapy for cancer are taking that advice a step further as they develop a new treatment that “starves” tumors to death.

Cutting Off Cancer’s Fuel Source

Glutamine is an amino acid found throughout the body, with the largest concentrations in blood and bone. While glutamine plays a major role in cellular synthesis of proteins, it also provides fuel for the rapid cell division of many types of cancer.

A research team at Vanderbilt University in Nashville began exploring the idea of blocking glutamine from cancer cells as a possible form of treatment. They focused on ASCT2, a protein that transports glutamine to cancer cells as well as other parts of the body.

The scientists created an ASCT2 inhibitor called V-9302. In testing on both mice and cancer cells developed in vitro, V-9302 was able to stop tumor growth by increasing oxidative stress on cancer cells, leaving them to eventually die off.

Using PET Imaging to Trace Tumors

As the team noted in their report, the next step is to find a way to determine how effective the inhibitors are in restricting glutamine access. The researchers suggested using positron emission tomagraphy (PET) scans to spot increases in glutamine metabolic rates.

Swiss Group Studies Dendritic Cell Vaccines with Artificial Receptors

March 28, 2018 Chris

New Cancer Research Is Improving Treatment

One of the challenges doctors face with cancer treatment is designing a program to meet a patient’s unique needs. Immunotherapy for cancer is helping to provide solutions to this problem, such as recent improvements to dendritic cell vaccines.

Immunotherapy: Priming the Body’s Immune System

While the body’s immune system is extremely capable when it comes to fighting viruses, bacteria and other invaders, cancer cells often demonstrate a remarkable ability to evade detection. Immunotherapy works by enhancing the immune system’s power to target and destroy cancer cells.

Dendritic cells are one of the immune system’s “messengers” that present antigens to killer T-cells for destruction. Researchers in Switzerland began looking for a way to improve the effectiveness of dendritic cell vaccines.

Helping the Immune System Recognize Cancer Cells

Prof. Michele De Palma and his team created artificial receptors known as EVIRs, which are inserted in dendritic cells extracted from a patient. Once reintroduced into the patient’s system, the EVIRs are engineered to recognize exosomes that transport molecules between cells, sometimes assisting in the spread of cancer.

As EVIRs capture exosomes, it allows dendritic cells to present antigens on their outer surface, simplifying recognition and attack by killer T-cells. De Palma and his team have dubbed this phenomenon “cross-dressing,” and they’re hoping that the process will improve the specificity of cancer treatment.

New Understanding of High-Risk Neuroblastoma from Massachusetts Research

March 26, 2018 Chris

Issels the Premier Provider of Immuno Oncology

Neuroblastoma is a cancer of the sympathetic nervous system that affects primarily infants and children. Thanks to a Massachusetts-based research team, there is now more information about the growth of neuroblastoma that will aid the development of more effective cancer treatment.

“Hijacking” Healthy Cells

Neuroblastoma gets its name from neuroblasts, which are immature cells where this form of cancer develops. For this study, researchers focused on MYCN and c-MYC, two related proteins that have been linked to neuroblastoma’s progression.

In studying tumors from 123 neuroblastoma patients, the team discovered that 25 percent had MYCN applications and another 10 percent showed overexpression of c-MYC. While the groups didn’t overlap, both showed similarly poor survival rates.

Scientists then conducted a study with zebrafish and determined that c-MYC is a more powerful oncogene (a gene that has the potential to turn a normal cell cancerous) than MYCN, Results showed that c-MYC overexpression has a greater chance of creating neuroblastoma along with a shorter onset time.

Debut of 3D Genomics

Another exciting aspect of this study is that it was the first use of 3D genomics. A technology known as Hi-C, or in situ chromosome conformation capture, helps researchers study genomic interactions to identify abnormalities.

Since c-MYC can be detected in the clinic, scientists are hoping that they’ll eventually be able to develop a new cancer treatment that targets and degrades the protein.

Will CRISPR Gene Editing Play a New Role in Cancer Treatment?

March 23, 2018 Chris

New Research Is Unlocking the Mystery of Cancer

As science makes connections between DNA mutations and cancer, gene-targeted therapies have become a valuable way to make cancer treatment more effective. Now researchers are pondering how advanced genome editing technology might impact the future of cancer research and treatment.

Solving the Puzzle of DNA

All biological lifeforms are composed of three primary substances. DNA, the building block of genes, uses RNA as a messenger to control proteins, which are the cellular “worker bees.” RNA and proteins can be targeted with drugs, medicines and other treatments, but DNA is more complicated.

CRISPR is a process that lets scientists actually manipulate and make changes to genetic material in cells. In theory, CRISPR could be used to “edit” diseases such as cancer right out of patients.

Can Genetic Editing Improve Cancer Treatment?

Finding the precise genes that drive cancer development can be like looking for a needle in a haystack. With the help of CRISPR, researchers can replace normal genes with cancer-causing ones to get a better picture of how the mutations work and thereby create more effective treatment solutions.

According to Dr. Irene Chong, a clinical scientist at the Institute of Cancer Research in London, the precision of CRISPR holds possible ramifications for future cancer treatment. Doctors may eventually be able to target and correct genetic mutations that cause a predisposition to cancer.

Personalized Dendritic Cell Vaccines As Effective Immunotherapy Make the News

March 21, 2018 Chris 1 Comment

One of the benefits of immunotherapy for cancer is that treatments can often be tailored to address a patient’s individual needs. Scientists in Switzerland have now developed a method of modifying dendritic cell vaccines that makes them easier to personalize.

Aiding the Body’s Own Immune Response

Dendritic cell vaccines are normally created by force-feeding dendritic cells with tumor antigens. Scientists at the Swiss Institute for Experimental Cancer Research have developed a modification that allows dendritic cells to acquire antigens from a patient’s tumor.

Prof. Michele De Palma, winner of the 2017 Swiss Cancer League award, led the team of researchers in creating an extracellular vesicle (EV)-internalizing receptor, referred to as EVIR. The EVIR has been optimized to enhance dendritic cells and their ability to selectively uptake cancer cell-derived EVs.

Antigen-laden exosomes and other extracellular vesicles are released by tumors in sizable quantities. The EVIR helps dendritic cells target the exosomes more precisely and present them to killer T-cells for a more efficient immune response.

Streamlining the Job of Dendritic Cells

De Palma explained the phenomenon of cross-dressing, in which dendritic cells display the acquired antigens directly on their surface. The process simplifies the immune response by eliminating the need for more complex interactions within the dendritic cell itself.
