A Trojan horse? Immune cells ferry deadly fungus from mouse lung into the blood
A report today (June 27) in PLOS Pathogens shows how inhaled fungal spores exit the lung and trigger a fatal infection in mice.
The study solves a mystery of mycology: Why are spores of a certain fungal strain deadly while the yeast form of that same fungus is harmless?
Study leader Christina Hull, professor of biomolecular chemistry and medical microbiology and immunology at the University of Wisconsin–Madison, focuses on Cryptococcus, the most deadly inhaled fungus. The short answer, she says, is that lung macrophages abandon their posts as bodyguards and begin smuggling spores into the bloodstream.

Peter Lewis Selected as Shaw Scientist
Milwaukee, Wis., May 21, 2015 – Two University of Wisconsin researchers – one investigating the genetic basis of cancer growth and the other, the role of genes in neural development and learning – have earned funding and a prestigious honor from the Greater Milwaukee Foundation.
Peter Lewis, Ph.D., assistant professor of biomolecular chemistry in the School of Medicine and Public Health, and Marc Wolman, Ph.D., assistant professor of zoology in the College of Letters and Science, have each received a $200,000 grant through the Foundation’s competitive Shaw Scientist Program. The annual award supports emerging investigators with innovative ideas in biochemistry, biological sciences and cancer research. Since the dollars are unrestricted, researchers can use their Shaw Scientist Award to develop preliminary data essential in competing for federal research funding.
“For more than three decades, the Shaw Scientist Program has rewarded the innovation of young investigators by providing valuable seed funding for their work,” said Ellen M. Gilligan, president and CEO of the Greater Milwaukee Foundation. “Developing better treatments for disease takes an investment in promising research, and private philanthropic support can help move these projects out of the starting gate.”
Understanding how mutations cause cancer.
Overall, Dr. Lewis is studying how changes in the chemical composition of DNA and the proteins that package the human genome (together known as chromatin) influence whether particular genes are activated or silenced in a given type of cell. His current work relates to childhood cancers. Recent studies have shown that many pediatric cancers likely stem from mutations that cause a change in chromatin structure.
“The improper activation or silencing of genes can promote tumor formation by altering the normal pathways that keep cells from proliferating uncontrollably, a common feature of cancer cells,” Dr. Lewis said. “In addition to advancing current diagnostics, our present work will also identify new molecular targets for future therapeutic intervention of these devastating malignancies.”
Securing federal funding for promising new ideas can be challenging, because there is less data to demonstrate the merit of a novel design. The Shaw Scientist Award provides the means to pursue an experimental approach, Dr. Lewis said.
Dr. Lewis earned a bachelor of science from University of Virginia and a Ph.D. from University of California-Berkeley. His post-doctoral training was completed at The Rockefeller University.
Lewis Selected as Kimmel Scholar
Congratulations to Peter Lewis for his selection as a 2016 Kimmel Scholar!!! The Sidney Kimmel Foundation for Cancer Research funds the Kimmel Scholars Program, which each year, through a distinguished medical board of advisors, provides research grants to the nation’s most promising young cancer researchers. To date there have been 247 recipients of these awards. The goal of the grant program is to improve the basic understanding of cancer biology and to develop new methods for the prevention and treatment of cancer.

Dahlberg Wins Basic Sciences Emeritus Faculty Award
Dr. James Dahlberg was awarded the 2015 Basic Sciences Emeritus Faculty Award by the Wisconsin Medical Alumni Association .Dr. Dahlberg joined the Department of Biomolecular Chemistry in 1969 as an assistant professor and moved quickly through the ranks, becoming full professor in 1974.
Dr. Dahlberg’s cutting-edge research on the basic structure and function of nucleic acids, particularly in RNA, has had a profound impact on our understanding of nucleic acid metabolism in both normal and disease states. He has over 150 peer-reviewed publications and 37 issued US patents. The impact of his work and the respect of his peers is evidenced by his election to the National Academy of Sciences, the American Academy of Arts and Sciences and the European Molecular Biology Organization (EMBO).
Dr. Dahlberg became a professor emeritus in 2005, but continues to be active in his research and his service. He also recently served as interim director and associate director of the Morgridge Institute for Research.
Through his scientific discoveries, entrepreneurship, teaching and service, Dr. Dahlberg has played a key role in making the University of Wisconsin School of Medicine and Public Health the outstanding institution that it is today. April 24, 2015
Hull Awarded Hartwell Foundation Grant
Dr. Christina Hull is one of two University of Wisconsin-Madison researchers have received three-year Hartwell Individual Biomedical Research Awards to support research into fungal disease and therapy for attention deficit hyperactivity disorder (ADHD).
Hull, associate professor of Biomolecular Chemistry, is funded to explore Cryptococcus, a fungus that causes brain infections in people with immune deficits due to cancer treatment, transplant or AIDS. Hull will focus on the spore — the transmissible phase of the fungus — with the goal of understanding how the spore transforms itself into a yeast cell, which can cause brain swelling, blindness and death.
Using high-speed technology at UW-Madison, Hull will screen for drugs that can either block that transformation or treat the yeast infection without unacceptable side effects. “There are not many antifungal drugs, and some of them are quite toxic, because humans and fungi are close relatives,” she says. “If you could give a nontoxic spore-blocking drug to a transplant patient when they start taking drugs to suppress the immune system, that would stop the disease process even if they inhaled these spores.”
Fungal diseases are a growing problem, Hull says. “Fungal spores are ubiquitous in soil and when we stir it up and inhale them, a whole range of infections can start. But if the inhaled spore cannot grow, it cannot cause disease, so learning to block that process could be key in the prevention of many fatal fungal diseases.” The grant will also fund studies on the role that fungal spores play in allergic asthma.

Chanda Awarded Romnes Fellowship
Dr. Baron Chanda, professor of Biomolecular Chemistry and Neuroscience is one of nine promising young members of the UW-Madison faculty to have been honored with Romnes Faculty Fellowships.
Romnes awards recognize exceptional faculty members who have earned tenure within the last six years. Selected by a Graduate School committee, winners receive an unrestricted $50,000 award for research, supported by the Wisconsin Alumni Research Foundation (WARF).
The award is named for the late H. I. Romnes, former chairman of the board of AT&T and former president of the WARF Board of Trustees.
Dr. Chanda studies mechanisms of gating and modulation of biological ion channels, molecules involved in generating electrical activity in the brain and heart. His laboratory has developed sophisticated tools to study protein dynamics, and created a temperature-sensitive ion channel that rivals naturally occurring channels.
