The longer lifespans we enjoy come shadowed by age-related diseases, notably Alzheimer's. This episode shines a light on the often-overlooked glycans, complex carbohydrates that play a pivotal role in healthy brain function. Our understanding of Alzheimer's causation has evolved, moving beyond just 'trash accumulation' to include problems with 'trash clearance.' Discover the potential of glycans in healing spinal cord injuries, the hurdles in identifying early biomarkers and delivering drugs to the brain. We delve into the essential role of gangliosides, a unique class of glycolipids, and separate science from media hype around Alzheimer's prevention. Ronald Schnaar is the Professor and Interim Director of the Department of Pharmacology and Molecular Sciences and a Professor of Neuroscience at Johns Hopkins University School of Medicine.

It is a widely known fact that cardiovascular diseases are the leading cause of mortality and morbidity in both men and women, which puts an urgency on gaining a better understanding of them. One interesting lens to look at CVDs is through glycans. However, in order to do so, we need to uncover the answer to which came first, the chicken or the egg? Do glycans change in response to the disease? Or are they actively involved in disease development? To figure this out, we welcomed Prof. Samia Mora to the podcast. Samia is a Professor of Medicine at Harvard Medical School and Director of the Centre for Lipid Metabolomics at the Brigham and Women’s Hospital in Boston, Massachusetts. Her research focuses on risk factors and prevention of cardiovascular diseases (CVDs). Listen in as she introduces us to a number of modifiable risk factors and the cumulative effect both positive and negative behaviours have on future disease risk.

Glycosylation, a biological process vital to life, is likely something you’ve never heard of before. It involves the addition of sugar molecules, known as glycans, to proteins and lipids which enable a number of crucial physiological functions, from immune regulation to cell-to-cell communication. This episode explores what happens when genetic mutations disrupt the glycosylation pathway as well as the detective work and collaboration required to diagnose and treat the resulting conditions. Hudson Freeze is the Director of the Sanford Children’s Health Research Centre and the Human Genetics Programme at Sanford Burnham Prebys Medical Discovery Institute, his research focuses on Congenital Disorders of Glycosylation, or CDG for short. Listen in as he reflects on the adventurous road to discovery of these rare conditions, the unlikely therapeutic options, the knowledge gap within the medical and scientific communities, and how a single discovery at Yellowstone National Park changed the course of history.
We Discuss:

The concept of biological age might sound like a new notion, but it’s something researchers have been looking at for 35 years. A person’s biological age can tell us more about them than chronological age because it includes genetics, lifestyle and environmental factors. Since it’s such an individualised metric, it’s important to find a reliable way of measuring it. In the episode, Rina and her guest Dr Peter Joshi describe 11 different biological ageing clocks, the research behind them and why GlycanAge is such a great tool for providing not just an accurate measurement of your biological age, but also actionable tips you can incorporate to promote healthy ageing. Our guest is a Chief Scientist for Humanity Health, a company using digital biomarkers to measure and improve the rate of ageing.
We Discuss:
How has our understanding of ageing changed [02:43] What are the hallmarks of ageing [11:15] Explaining the term biological age [14:25] Multi-omics analysis of biological age [20:50]Are biological clocks predictive of chronological age [26:21]The benefit of measuring biological age [43:36]How to improve the biological clocks [46:45]Follow Peter on social media

How much control do we have over our health? The study of epigenetics made us aware of the remarkable malleability of our phenotype, prompting closer investigation on how lifestyle and environment impact our health and longevity. In this context, glycans - a class of historically understudied biological polymers may hold the key to a better understanding of the interplay between genetic and epigenetic factors contributing to disease development. Olga Zaytseva is a post-doctoral researcher at Genos Glycoscience Research Laboratory in Croatia, her research focuses on the relationship between human diseases and the regulation of antigen-specific IgG glycans. Listen in as she unravels the latest research on genetic and epigenetic regulation of IgG glycosylation and introduces us to the role of environmental factors in common diseases, from obesity to depression.

Glycans have a great capacity to fine-tune the inflammatory response and often determine how successfully the immune system distinguishes between friend and foe. While cancer cells build a glycan shield to hide from immune surveillance, pathogens can mimic our glycans in order to evade immune detection and perpetuate infection. Salomé Pinho is the Immunology, Cancer and GlycoMedicine Group leader at the Institute for Research and Innovation in Health at the University of Porto, her research focuses on cancer and inflammatory conditions. Listen in as she introduces us to the intricacies of immune regulation and the potential of glycans as diagnostic and prognostic biomarkers as well as immunotherapeutic targets.

Despite the buzz around novel cancer therapies, the harsh reality is that most only extend life expectancy by a few months. Dr Azra Raza, a Professor of Medicine, and the Director of the MDS Centre at Columbia University, has a different approach. Azra argues that the key to defeating cancer lies in early detection, and she has dedicated over 35 years of her career to collecting samples and researching myelodysplastic syndromes (MDS) with the goal of catching cancer at its earliest stage. Listen in as she discusses her ground-breaking work and her belief that we are entering a new cancer parading. Dr Raza is leading the charge with a coalition of 8 leading institutions in the USA.
