MMBioS Having a Big Impact
As MMBios enters its 5th year, we took some time to reflect on the impact that our Resource has had. We are bolstered by the extensive use of our technologies and software by investigators both inside and outside of MMBioS. To date, over 120 publications have acknowledged the MMBioS award, and these high quality papers have already been cited over 550 times! We look forward to the advances that lie ahead and to the sustained impact of MMBioS!

Modeling with BioNetGen Gives MMBioS Team Insight into How Immune System Decides to Attack — or Let Be
Friend or Foe?
A mix of computer modeling and laboratory experiments has helped reveal how the body differentiates “friend from foe.” Using their BioNetGen computer tool for simulating biochemistry, MMBioS members and colleagues have painted a sharper picture of how T cells, the advance scouts of the immune system, decide when to protect bodily tissues from immune attack—and when to lead the attack. The finding may guide future efforts to control human diseases like diabetes and cancer.
When T cells—a type of white blood cell—encounter other cells in the body, “they have to decide what kind of a response to make,” says James Faeder, project co-leader of MMBioS’s Technology Research and Development Project 2 Team and associate professor of computational & systems biology, University of Pittsburgh. “Is that a threat, or is it something benign? Depending on their assessment of a possible threat they can either become activated, immune-boosting cells that kill pathogens, or they can tamp down those responses.”

Bahar participates as an invited speaker at the White House for the National Strategic Computing Initiative
Dr. Ivet Bahar was invited to participate in a workshop and give a talk at the White House for the National Strategic Computing Initiative (NSCI).
On July 29, 2015, the President issued an Executive Order creating the NSCI, a whole-of-Nation effort to maximize the benefits of high-performance computing (HPC).
The workshop brought together 75 leaders from industry, academia, and government to discuss opportunities of HPC and solutions to the challenges faced. Dr Bahar participated in the meeting as one of the three invited speakers from academia. She presented her perspective on what is the state-of-the-art in computational biology using her NIH-funded Biomedical Technology and Research Center’s focus as a lens, and discussed current challenges that could be addressed by exascale computing through NSCI. The title of her talk was, “Exascale Computing for Multiscale Modeling and Big Data in Biology”.

Congratulations to our recent graduates
Two MMBioS team members recently completed their Ph.D. work.
Congratulations to Dr. Rory Donovan, who successfully defended his thesis, “Efficient Sampling in Stochastic Biological Models” on May 31. Rory joined CPCB following his MS in Physics at U. of Washington, and his BA in Physics at Reed College, and was advised by CPCB co-Director Dr. Daniel Zuckerman.
Rory came back to Pittsburgh to defend his thesis, as he had already begun his position as a postdoctoral fellow in the lab of Dr. Nathan Price at the Institute for Systems Biology in Seattle. In addition to celebrating his PhD, we are also eagerly awaiting news of the arrival of his first child!
Jose Juan Tapia-Valenzuela
Congratulations to Jose for successfully defending his dissertation, “A study on systems modeling frameworks and their Interoperability”. Jose was a member of the Faeder lab during his time at CPCB, and now will continue to work with Jim.

Zuckerman and Faeder Receive R01 Grant
Dr. Daniel Zuckerman (PI), in collaboration with Dr. Lillian Chong (PI) and Dr. James Faeder (Co-I), was awarded an NIH R01 grant for $1.3 million over 4 years. The grant is titled “High-Performance Weighted Ensemble Software for Simulation of Complex Bio-Events”.
In response to a call from NIH, the aims are to provide open-source software to enhance the power of simulations at any scale (e.g. molecular, cellular) for a potentially large user base. Thus, the primary impact will be to facilitate key segments of the burgeoning field of computational biomedical research. Additionally, research to be performed directly by the investigators is designed to yield insights into cancer and neurological processes with potential to enhance drug design efforts.

Murphy & Wülfing receive grants from new international collaboration program
MMBioS investigators Bob Murphy (Carnegie Mellon University) and Christoph Wülfing (University of Bristol) have just received grants from a new program encouraging collaboration between U.S. and U.K. investigators. The program, run jointly by the U.S. National Science Foundation (NSF) and the U.K. Biotechnology and Biological Sciences Research Council, allows the investigators to submit a single proposal that is reviewed by only one of the agencies: if it scores highly, the second agency simply accepts the recommendation of the first. The project builds on initial work funded by NSF and subsequent work done through MMBioS that led to a recent major paper in Science Signaling. The project will involve analyzing fluorescence microscope movies to create spatiotemporal maps of proteins involved in signaling by T cells, a key component of the immune system. The maps will be combined with data on cell-wide protein phosphorylation and used both to infer potential signaling complexes, and to estimate the apparent affinities and potential causal relationships amongst proteins involved in T lymphocyte signaling.

Murphy and Faeder organize NIMBioS Working Group for Spatial Cell Simulation
The National Institute for Mathematical and Biological Synthesis has announced support for a working group on Spatial Cell Simulation based on a proposal by Bob Murphy and Jim Faeder, both of whom are project leaders in MMBioS. Systems biology emphasizes the creation of mathematical or computational models of biological systems such as cells and tissues, as a means both to integrate all available information and to make predictions about unmeasured mechanisms or behaviors. The working group will address critical challenges currently faced in creating mathematical/computational simulations of the inner workings and dynamics of eukaryotic cells that reflect realistic cell architecture, especially for accurately simulating changes in cell shape and organization over time.
The issues to be addressed include methods for simulation that can consider dynamic cell and organelle shapes and positions and methods for learning joint probability distributions for thousands of cellular components. The working group will meet 2-3
times per year to develop new approaches to these problems, implement them in software, develop proposals for future funding of such research, and develop training materials for biomedical researchers. The first meeting will be December 1-3, 2015.

Major New Release of CellOrganizer 2.0
A major new release of the CellOrganizer system for creating image-derived models of cell shape and organization has just been published. The software is a major focus of research supported by the NIH through the National Center for Multiscale Modeling of Biological Systems (MMBioS). It creates statistical, generative models of cell and nuclear shape, microtubule patterns, and vesicular organelles that can be used as the basis for cell simulations (another focus of MMBioS). Generative models capture not just a description of a pattern but the ability to produce new examples of that pattern (analogously to the way in which humans capture models of letters or spoken words not just by describing them but by learning to produce new examples). Support for CellOrganizer has also come from NIH grants GM075205 and GM090033.
