Rewind: What Determines Who Gets a Transplant? with Daniela Ladner, MD, MPH

We are re-sharing an episode that we originally released in fall 2023 about transplant science with Daniela Ladner, MD, MPH. She is the founding director of the Northwestern University Transplant Outcomes Research Collaborative, or NUTORC, and is committed to leading collaborative research that seeks to identify the barriers to transplant access and improve outcomes for patients, even those who may never get a transplant. In this episode, she discusses a study into the personalities of patients with cirrhosis and some interesting results that may inform new ways to communicate with and help these patients. 

Why does a standard immunotherapy work remarkably well for some bladder cancer patients, but fail for others? In this episode, Northwestern Medicine physician-scientist Joshua Meeks, MD, PhD, breaks down his recent research published in the Journal of Clinical Investigation and European Urology uncovering how the tumor microenvironment and immune cellular communication influence response to Bacillus Calmette-Guérin (BCG) immunotherapy. Find out how single-cell RNA sequencing, macrophage–T-cell interactions, and urinary tumor DNA biomarkers are paving the way for targeted, personalized bladder cancer care. 

We are re-sharing an episode that we originally released in March 2023 about circadian rhythms and metabolism, looking at how the timing of food consumption can impact weight gain and health. Since this episode was released Dr. Bass has led several other studies looking at circadian rhythms and weight loss. Most recently, his team published in the Proceedings of the National Academy of Sciences about an experimental RNA therapy that induces the body to burn calories and preserving lean mass, thereby enhancing the benefits of GLP-1s. More on the recent study can be found here: https://news.feinberg.northwestern.edu/2026/09/21/rna-therapy-may-help-preserve-muscle-during-glp-1-weight-loss/

Why does one person become critically ill from a virus while another person exposed to the same microbe remains completely healthy? This is the "infection enigma," and Jean-Laurent Casanova, MD, PhD, has spent his career trying to solve it. A French pediatrician and immunologist, Casanova is the winner of Northwestern University's 2026 Mechthild Esser Nemmers Prize in Medical Science. In this episode, Casanova discusses his paradigm-shifting discoveries and what they reveal about immunity, genetic predisposition and why some people develop life-threatening infections while others do not. 

For decades, biomedical research relied heavily on male subjects, leaving important gaps in our understanding of how diseases and treatments affect women. In 2016, the NIH introduced a policy requiring that all eligible funding applicants consider the influence of sex in their research to better understand health and disease for all. Nearly a decade later, has research truly changed? In this episode, Nicole Woitowich, PhD, executive director of Northwestern University Clinical and Translational Science Institute (NUCATS), discusses her new study examining how well biomedical research is incorporating sex differences, and where science is still falling short.  Read more about Woitowich's appointment as executive director of NUCATS. Check out the study published in Nature Communications Medicine. Learn more about the research from a Northwestern Now story.

In this episode, Peter Penzes, PhD, director of the Center for Autism and Neurodevelopment at Northwestern University Feinberg School of Medicine, discusses a recent discovery of a schizophrenia biomarker and how this research could one day offer earlier diagnosis, more precise treatment, and better outcomes for patients.  Learn more about how the field of neurodevelopmental research has evolved over the past decade with major advances in genetics, brain imaging and laboratory models. Large genomic studies have uncovered many more genes associated with risk of developing autism, schizophrenia and related conditions, while new technologies, including brain organoids grown from patients' stem cells, are giving scientists new insight into how these disorders develop and affect brain function.

Fetal surgery can be lifesaving for babies diagnosed with complex conditions before birth, but it comes with significant challenges, including limited ability to monitor the fetus in real time. A Northwestern Medicine team has developed a first-of-its-kind flexible probe, designed for continuous real-time fetal monitoring during surgery.   This innovation is the result of a collaboration between Northwestern University bioelectronics pioneer John Rogers, PhD, and Aimen Shaaban, MD, director of the Chicago Institute for Fetal Health. In this episode, Shaaban explains how the device works, how the collaboration took place and what it will take to bring this technology out of the lab and into clinical care. 

As the new chief of Infectious Diseases at Northwestern University Feinberg School of Medicine, Jennie Kwon, DO, is working in a rapidly evolving field rich with opportunities for discovery and impact. Her own research focus is one of the most pressing challenges in medicine today: antimicrobial resistance.  In this episode, she discusses the growing global threat of antimicrobial resistance and why this crisis could fundamentally disrupt modern medicine. 

We are re-sharing this episode on dopamine and subtypes of dopaminergic neurons that may provide new insights into how we think about the role of dopamine. Rajeshwar Awatramani, PhD, and Daniel Dombeck, PhD led this research, and in this episode they explain how the results could change the field of dopamine research and pave the way for new research possibilities, especially concerning Parkinson's disease, a condition marked by a loss of dopamine neurons and motor system challenges.  

A new, rapid Hepatitis C test developed by Northwestern University scientists could change the future of Hepatitis C care by delivering faster diagnosis and treatments for a disease that is estimated to impact 50 million people around the world. The research behind this new test, which was built on the DASH (Diagnostic Analyzer for Specific Hybridization) Rapid PCR system developed at Northwestern University was published in the Journal of Infectious Diseases. In this episode, Claudia Hawkins, MD, MPH, explains this study and the impact this test could have on the global effort to eliminate Hepatitis C.
