A systems biology approach to understanding the immunobiology of tuberculosis infection and treatment
Abstract: Tuberculosis (TB) is one of the world’s deadliest infectious diseases. Caused by the pathogen Mycobacterium tuberculosis (Mtb), the standard regimen for treating TB consists of treatment with multiple antibiotics for at least six months. There are a number of complicating factors that contribute to the need for this long treatment duration and increase the risk of treatment failure. The structure of granulomas, lesions forming in lungs in response to Mtb infection, create heterogeneous antibiotic distributions that limit antibiotic exposure to Mtb. We can use a systems biology approach pairing experimental data from non-human primates with computational modeling to represent and predict how factors impact antibiotic regimen efficacy and granuloma bacterial sterilization. We utilize an agent-based, computational model that simulates granuloma formation, function and treatment, called GranSim. A goal in improving antibiotic treatment for TB is to find regimens that can shorten the time it takes to sterilize granulomas while minimizing the amount of antibiotic required. With the number of potential combinations of antibiotics and dosages, it is prohibitively expensive to exhaustively search all combinations to achieve these goals. We present a framework to search for optimal regimens using GranSim. Overall, we present a computational tool to evaluate antibiotic regimen efficacy while accounting for the complicating factors in TB treatment to strengthen our ability to predict new regimens that can improve clinical treatment of TB.
Bio: Dr. Kirschner received her Bachelors, Masters and PhD in applied mathematics from Tulane University. She did graduate work also at Los Alamos National Labs and a postdoctoral fellowship at Vanderbilt University joint with the departments of Mathematics and Infectious Diseases. Over the past 25 years Dr. Kirschner has focused on questions related to models of host-pathogen interactions in infectious diseases. Her main focus has been to build models of persistent infections (e.g. Helicobacter pylori and Mycobacterium tuberculosis and HIV-1). Her goal is to understand the complex dynamics involved, together with how perturbations to this interaction (via treatment with chemotherapies or immunotherapies) can lead to prolonged or permanent health. For the past 20 years, her research focus has been on building multi-scale models to describe the host immune response to M. tuberculosis at multiple spatial and time scales and in multiple physiological compartments including lung, lymph nodes and blood. To date she have worked and collaborated with experimentalists generating data on TB with mouse, non-human primate and human studies. Denise has over 150 publications in top journals describing this work that spans topics from methodological to biological advancement. Dr. Kirschner currently serves (and has for the past 17 years) as Editor-in-Chief of the Journal of Theoretical Biology. She serves as the founding co-director of The Center for Systems Biology at the University of Michigan, an interdisciplinary center at the University of Michigan aimed to facilitate research and training between wet-lab and theoretical scientists. In 2016 she was elected as President-elect of the Society for Mathematical Biology and has served as its president from 2017-2020. Denise’s passion for mentoring students, postdoctoral fellows and junior faculty has been a major focus of her career, and her key mission is to promote both mathematics and family values in the scientific community.

New Multicampus Consortium to Study Assembly of Coronaviruses
The University of California, Riverside, is the recipient of a 2021 UC Multicampus Research Programs and Initiatives, or MRPI, award allowing the campus to put together a UC Coronavirus Assembly Research Consortium.
“This consortium will aim to understand the physical principles underlying the formation of coronaviruses,” said Roya Zandi, a professor of physics and astronomy at UC Riverside and the principal investigator of the four-year project that received funding of more than $1.75 million. “We will also explore the impact of some drugs on the assembly process.”
UCR will be joined by UC Merced and UC Davis in the consortium. The three campuses will work together to understand the factors contributing to the formation of SARS-COV-2.
UC Riverside Study Focused on How HIV Mutates to Escape the Immune System
A team co-led by a scientist at the University of California, Riverside, has developed a method to study how HIV mutates to escape the immune system in multiple individuals, which could inform HIV vaccine design.
HIV, which can lead to AIDS, evolves rapidly and attacks the body’s immune system. Genetic mutations in the virus can prevent it from being eliminated by the immune system. While there is no effective cure for the virus currently available, it can be controlled with medication.
“Understanding the genetic drivers of disease is important in the biomedical sciences,” said John P. Barton, an assistant professor of physics and astronomy at UCR, who co-led the study with Matthew R. McKay, a professor of electronic and computer engineering and chemical and biological engineering at the Hong Kong University of Science and Technology.
Study Reveals How Cells Control What They Produce After Eating

Co-sponsored by UCR Math’s Interdisciplinary Center for Quantitative Modeling in Biology and the Lorentz Center In Leiden, The Netherlands, Dr. Mark Alber co-organizes the Summer School “Modeling of Shape and Size in Biological Development”
Students are encouraged to participate in online activities including listening to review talks and working on introductory projects. These activities will culminate in intense training and exchange program from 24 to 28 August, 2020.
A follow up Special Session to be held at the 2021 Annual SMB Meeting, June 13-17, 2021 at UCR as well as a Workshop at the Lorentz Center sometime in 2021-22 are planned.
The Summer School focuses on mathematical multiscale models of animal and plant development and plant growth. School participants will work with models rooted in the cellular level, i.e., models making links between cellular processes such as cellular growth and division, cell movement and interaction with the extracellular matrix (ECM), mechanical or chemical signaling between cells, etc., leading to organ shape development and growth at higher spatial scales.
Graduate students will be exposed to state-of-the-art examples of multiscale modeling in development. They will get hands-on experience with the development of mathematical and computational models as well as model calibration using experimental data. They will also develop in teams simple, but novel example models to answer open scientific questions proposed by the speakers ahead of time. Students will be expected to already have some experience in modeling but will be asked to work with a method that is new to them.

Title: Elucidating Principles of Bacterial-Fungal Interactions
Abstract: In comparison to bacterial-bacterial interactions, there is very little known about bacterial-fungal interactions even though these interactions are thought to be fundamentally important to DOE missions in sustainability, crop biofuel development and biosystem design. In biofuel crops, many crop root systems live in mutualistic symbiosis with fungi and bacteria. Mycorrhiza helper bacteria (MHB) increase host root colonization by mycorrhizal fungi, which in turn act as a micro-root system to provide the plant with soil nutrients. Recent work on the Populus root microbiome has determined that the interactions between the mycorrhizal fungus Laccaria bicolor and the bacterium, Pseudomonas fluorescens are key to the fitness of the plant. These organisms, Laccaria and P. fluorescens, are the focus of this project to use combined mathematical and computational modeling and experiments to understand fundamental principles of interactions between fungi and bacteria from the perspective of material exchange and energetics, and how material and energetics are linked in inter- and intra-microbial subsystems.
