Reading time: 4 minutes Taylor B. Poston, Ph.D., M.P.H. Most tumors do not respond to T-cell based immunotherapies, but the explanation for this phenomenon has been unclear. Researchers have speculated that there could be insufficient priming of anti-tumor T cells, or if T cells are primed, they are unable to recognize and eradicate the tumor.... Continue Reading →
Pembrolizumab – the miraculous drug
Reading time: 5 minutes Varshit Dusad A cancer diagnosis is generally perceived to be a death sentence. With millions of people dying of cancer every year, this does not seem to be at all outrageous. However, researchers all over the world, in academia and industry alike, have been relentlessly pursuing novel therapies and drugs to... Continue Reading →
It takes two brakes to stop cancer?
Reading time: 4 minutes Manisit Das In the past, we have discussed checkpoint inhibitors - therapies that block communication between cancer and immune cells, preventing cancer cells from evading the immune system. Dr. James Allison and Dr. Tasuku Honjo, who won the Nobel Prize in Medicine in 2018 for their pioneering work in cancer immunotherapy... Continue Reading →
Overcoming the Limitations of CAR-T Therapy: Cytokine Storm
Reading time: 3 minutes Alex S. Woodell A warm breeze whips by as you notice a peculiar set of clouds forming in the distance. These cumulus clouds are tall with bumpy protrusions that flatten out near the top to form a silhouette of a giant anvil. As condensation builds in these behemoths, the bright sunlight...

Too Much Potassium Might Be Poisoning Your Anti-Tumor Immunity
Reading time: 4 minutes Sara Musetti Cancer immunotherapy has been a very hot topic here at OncoBites (because it’s a hot topic right now among cancer researchers too), but let me be super clear ⎯ it is COMPLICATED. Your immune system is balanced extremely delicately to avoid sending you into shock each time you are... Continue Reading →
Overcoming the Limitations of CAR-T Therapy: Burnout
Reading time: 4 minutes Alex S. Woodell Marathon runners are an interesting breed. In order to complete the grueling 26.2 mile circuit, they must push their mental and physical boundaries to the limit. Seasoned runners possess great strength, focus, resilience, and determination. Each of these qualities is a testament to the intense training schedules they... Continue Reading →
Sneaking into the non-conventional niches: Using gamma delta T cells to fight cancer
Reading time: 6 minutes Payal Yokota Despite the advent and access to a variety of targeted immunotherapy approaches, the current paradigm for solid tumors still remains if you can cut it out – you do! Depending on the grade of tumor and degree of metastasis, there’s a substantial risk of tumor resurgence. In those cases,... Continue Reading →
Recombinant cytokines: The original cancer immunotherapy
Reading time: 4 minutes Bekah Schulz Many people are excited about checkpoint inhibitors in cancer immunotherapy. In fact, the 2018 Nobel Prize in medicine was awarded for the development of two checkpoint inhibitors PD-1/L1 (Opdivo/Keytruda) and CTLA-4 (Yervoy). However, cancer immunotherapy is not a new concept. In fact, in 1986, recombinant interferon (IFN) alpha was... Continue Reading →
Vaccines as Cancer Prevention and Therapies
Rachel Cherney Cancer is a complex set of diseases, characterized by uncontrolled growth and metastasis, destroying important organs and bodily systems. It can occur in almost any part of the body, and in most cases, it is impossible to determine how or when it will develop, certain genetically linked cancers perhaps being an exception. Because...

Cancer Immunotherapy wins the 2018 Nobel Prize
Sara Musetti and Manisit Das Early October is an exciting time of the year when people all over the world turn their eyes to Stockholm to see the winners of the Nobel Prize. Yesterday, James Allison and Tasuku Honjo jointly won the 2018 Nobel Prize in Medicine or Physiology for their work discovering the function... Continue Reading →
Dealing With The Pitfalls of Checkpoint Security
Jason Tetro If you’ve ever traveled internationally, you know you need a passport. This document is your access pass to the world. What you might not know is that this rather plain looking document is filled with a variety of different checkpoints to ensure authenticity. Some passports have biometric chips, others have incorporated images only... Continue Reading →
Helping Our Body’s Killers Kill off Cancer, Naturally
Nisitha Sengottuvel At OncoBites, we’ve talked about many facets of cancer, the many internal and external factors that can affect tumor growth, and the established and developing methods to detect and treat cancer. We’ve also begun to cover the many ways in which biomedical science falls short in effectively treating cancer. Being diagnosed with cancer... Continue Reading →
Can mental state affect tumor growth? The link between psychology, immunology, and oncology
Shaye Hagler At Oncobites, we’ve been talking a lot about the role of immunity in cancer. Understanding the immune system is vital to understanding both what drives cancer and what protects us against it. One of the biggest paradoxes in cancer research is that immune system activation is important in fighting cancer via a process... Continue Reading →
Immune cells work together to enable successful cancer therapy
Morgan McSweeney A group of researchers from the University of California - San Francisco recently found that the presence of a certain group of immune cells in tumors (“stimulatory dendritic cells,” or SDCs) can predict better cancer outcomes, at least in melanoma patients. For example, in patients treated with checkpoint inhibitors (drugs that work by... Continue Reading →
Stumbling before the beast: Not all cancer clinical trials end in drug approval
Manisit Das Since the beginning of OncoBites, we’ve talked a lot about immunotherapy: using our own immune cells to destroy the cancer cells? We can’t get enough of it! In one post, we highlighted a revolutionary approach recently approved by the US Food and Drug Administration (FDA) using genetically modified immune cells to fight cancer,... Continue Reading →
Immunotherapy in Pancreatic Cancer: Does Bacteria hold the answer?
Manisit Das Your gut is crawling with bacteria, despite your devoted hygiene practices. Disgusting for your sophisticated self, isn’t it? Surprising as it is, over the course of evolution our bodies tolerated the microbial communities in our body, even cherished them. Hundreds of thousands of bacteria and other microorganisms call us home and play a... Continue Reading →
Cancer Vaccines: Educating Your Immune System Since the 1800s
Sara Musetti Historians love to say that those who do not know their history are doomed to repeat it. In science, failing to remember and understand our history means that we may need to make the same discoveries again and again. This appears to be the case for cancer immunotherapy, a new branch of research... Continue Reading →
We’ve got a new FDA Approved Immunotherapy: How does it work?
Elizabeth Wayne, PhD Everything you need to fight cancer is inside of you. Well sort of. This is the inspirational way that I like to think of cancer immunotherapy. It’s using your own immune cells to fight cancer. We do this by trying to get immune cells to recognize cancer as a foreign pathogen, thereby... Continue Reading →
What exactly is cancer?
Sara Musetti I came to a realization this week. Here at OncoBites, we made a cancer research blog and then… forgot to tell our readers what cancer is. And I know, most of you reading are thinking “I know what cancer is!” because you read about it all the time. And maybe, if you’re a... Continue Reading →
From bacteria in your gut to cancer in your skin, everything is connected
Sara Musetti The word “bacteria” is often accompanied by a nose wrinkled in disgust and thoughts of infection and disease. Even though we have as many microbial cells as human cells within each of us—that’s right, we’re 50% bacteria—most people still find bacteria something to avoid. However, recent research into the gut microbiome, the ecosystem... Continue Reading →
