Evading the Immune System

Although our immune system is amazing at what it does, there are complex cases where the it fails us. Everyday, our bodies fight off hordes of bacteria and viruses that cause disease. When fighting cancer, our bodies even face their own cells that have gone rogue. However, certain pathogens and cancers manage to circumvent our immune system.

We talked to Dr. John Wherry, associate professor of microbiology and director of the Institute for Immunology at the University of Pennsylvania, about how the immune system is circumvented and what is being done about it.

Developing the Germ Cell

Cells are the building blocks of life…and need to be transformed into the various tissues that make up our body. There are two main populations of cells that are programmed by a variety of biochemical forces to acquire the characteristics of different cell types in the body. One population, called the somatic cells, is eventually transformed into skin, muscle, bones and such. The other population, called germ cells, becomes sperm and eggs.

In today’s episode, Karuna Meda interviews Dr. Nam Tran (UCSF) about his research on germ cell development and its importance for understanding fertility.

Trends in Translational Medicine

Under the banner of “Accelerating Research to Improve Health,” the Clinical and Translational Science Institute (CTSI) at the University of California, San Francisco -- the leading university exclusively focused on health -- is part of a shift in biomedical research.

This move involves a focus on translational, or bench-to-bedside research, which aims to “translate” biomedical discoveries into useful applications and treatments, such as a drug, device, diagnostic or behavioral intervention, that improves human health and health outcomes.

This podcast series is presented by the CTSI and Carry the One Radio – the Science Podcast. CTSI is funded by the National Center for Advancing Translational Sciences at the National Institutes of Health. This series was written and produced by Sama Ahmed and Karuna Meda, and edited by John Daigre and Carly Van Orsdel.

Getting in Touch with Emotions: Yelena Kulik

This CTOR Short by our producer Yelena Kulik examines how well (or not) people can convey emotions such as anger, love, and sympathy via touch. We eavesdrop on participants in the Berkeley Science Review's “Touch Me!” Event, which took place at the 2013 Bay Area Science Festival. We try to identify "best practices" for communicating emotions and we explore what happens when communication goes awry.

Run! for your brain: Gary Westbrook

Gary Westbrook
At one point in your middle school or high school biology class, you may have learned that the number of neurons in your brain is set at birth. For examples your skin cells are constantly dying and being renewed. Your brain cells, on the other hand, cannot be renewed once they die.

In the last decade, however, scientists have discovered that this is not entirely true. A part of the brain called the hippocampus is one of the few sites for adult neurogenesis (the production of neurons after birth). Here, neurons are constantly being produced throughout life and incorporated into the current network of neurons. Interestingly, this part of the brain is important for the formation of episodic memories. Our guest this week, Gary Westbrook, Senior Scientist and Co-Director at the Vollum Institute at Oregon Health and Science University, is working to understand this important process. His lab is interested in what causes the production of new neurons and the incorporation of these neurons into existing neuronal networks. They have found that simple exercise is enough to increase the production of new neurons in rodents. Tune in to hear more about this vital and fascinating process.

Chimeras are People Too: Kate Woronowicz

You may think that all of your cells contain the same genetic sequence, with half of your DNA coming from your mom and half coming from your dad, but that is not always true. This CTOR short will introduce you to chimeras, hybrid creatures with more that one genome, that can be man-made or naturally occurring.

Check out the CTOR interview with Dr. Rich Schneider who uses chimeras as a research tool.

CTOR also has a blog post about chimeras and genetic mosaics.

How Neurons Talk to Each Other - The Synapse and More: Susan Voglmaier

SusanVoglmaier
Your thoughts, decisions, emotions, and actions – essentially everything you do—relies on the incredibly complex circuits within your brain. Within these circuits, neurons signal to each other through a process called synaptic neurotransmission, whereby chemicals released by one neuron bind to receptors that are located on a neighboring neuron. This extremely complicated process requires an orchestra of protein interactions and is tremendously quick, taking place over about two thousandths of a second.

Given the importance of synaptic neurotransmission in how circuits function, and the role of circuits in cognition, it is not surprising that defects in synaptic transmission are thought to underlie mental illnesses such as schizophrenia. Today, we talk to Dr. Susan Voglmaier, a practicing psychiatrist and Assistant Professor in the Department of Psychiatry at UCSF. Dr. Voglmaier’s lab is interested in the process by which proteins called transporters prepare neurotransmitters for neurotransmission. Her research provides new insights into the basic molecular machinery underlying synaptic transmission, what might go awry in psychiatric disease, and, potentially, future ways to treat these diseases.

Tapping into the Brain's Avoidance Centers: Garret Stuber

GarretStuber
Traditionally, dopamine is known to transmit reward signals (food, sex, etc.) in the brain and promote behaviors that lead to that reward again. What you may not know, however, is that the area of the brain that releases dopamine, the ventral midbrain, also receives signals of aversion (things we find unpleasant or even dangerous) from a far-off brain region called the lateral habenula. These avoidance signals promote behaviors that lead us to avoid unpleasant or dangerous things in the world.

These brain circuits are necessary for survival and are the focus of Dr. Garret Stuber and his laboratory at the University of North Carolina - Chapel Hill. Using a tool known as optogenetics, Dr. Stuber can excite specific populations of neurons within mouse brains and observe their effects on behavior. For example, by stimulating the neurons in the lateral habenula that signal aversion, he can cause mice to avoid the location in which they received that stimulation. He is essentially creating an aversive stimulus by stimulating the neurons that would normally respond to harmful or unpleasant cues in the world. His work has important implications in addiction and psychiatric disorders
