Christine Grienberger Receives 2022 Smith Family Award

Grienberger Smith Family AwardChristine Grienberger, Assistant Professor of Biology, has received the 2022 Smith Family Awards Program for Excellence in Biomedical Research. This award is given to new faculty working in the field of biomedical research.

The following is a summary of Professor Grienberger’s research:

The brain has an extraordinary capacity to learn and to use past experiences to guide future behavior. When individuals learn, they create connections among features, e.g., the location of a restaurant and the food quality, to predict a future outcome. The hippocampal formation, a network of synaptically connected areas in the mammalian brain, is crucial for rapidly forming these associations and relaying them to the rest of the brain to drive learning. Our goal is to understand how the output region of the hippocampal formation, the subiculum, promotes this function. To this end, we will combine for the first time subicular whole-cell recordings, optogenetic perturbation of neural activity, and a spatial learning task. Our findings will provide novel insights into how basic cellular properties endow neurons in the currently poorly understood subiculum with the ability to affect learning. This work will also provide a starting point for investigating functional disruptions in neuropsychiatric disorders, in which the patients’ ability to learn is impaired, e.g., Alzheimer’s disease.

This will be a virtual one-day conference offered as part of the Brandeis Mathematical Biology Seminar.

This conference will bring together leading researchers in mathematical modeling related to climate change. It will cover techniques from mathematical modeling, data analysis and climate policy, and topics including impact of climate change on vegetation, animal populations, water/ice, carbon, and human health.

This virtual conference is part of the Brandeis Year of Climate Action program that will be occurring throughout 2022 and 2023. The Office of Sustainability is responsible for this program.


SARS-CoV-2 Nsp14 mediates the effects of viral infection on the host cell transcriptome

SARS-CoV-2 is the pathogen causing the COVID-19 pandemic, that as of early February 2022 has caused 5.7 million deaths worldwide.

When a virus infects a cell, it transforms it, so it can become a “virus factory”. To do so, it needs to suspend it from doing the normal functions, but not to a point that the immune system will detect those changes and “decide” to kill the infected cell. Understanding how viruses accomplish that is very important for virology and medicine as, for example, it could be used to help the immune system identify these cells and stop the virus from spreading through the body.

To tackle this issue, researchers identify genes that get activated or repressed when a virus infects a cell. One way to monitor the genes that are “on” or “off” during the infection is to measure RNAs abundance by RNA sequencing (RNA-seq). Through this approach, recent studies showed that SARS-CoV-2 infection induces big changes on the cells that it infects. Generally, scientists believe changes induced by viral infection are the consequence of the concerned action of the virus proteins acting within the host cell. For example, the SARS-CoV-2 genome encodes 29 proteins. The effect of the virus is so strong that it changes more than 5000 genes in just 48hs, this is almost ¼ of our genes.

How do individual viral proteins contribute to these changes? To answer this question, the Kadener lab in the Department of Biology introduced singular viral SARS-CoV-2 proteins into human cells and monitored gene expression changes through RNA-seq. Between the 26 tested proteins, non-structural protein 14 (Nsp14) was the one inducing the most dramatic effect, altering the expression of ≈4000 genes. Importantly, these changes overlap well with previously published RNA-seq data from human cells infected with SARS-CoV-2. This suggests that transient expression of Nsp14 partially recapitulates the molecular events downstream to SARS-CoV-2 infection. They also showed that a cellular enzyme (IMPDH2) mediates these changes, and that treatment with IMPDH2 inhibitors partially rescues the changes induced by Nsp14.

This research contributes to understanding the function of viral proteins on the host cell and on the molecular mechanisms that control the progression of viral infection. The Kadener lab showed that Nsp14 also modulates gene expression of the host cell by activating a cellular enzyme. These events may be conserved in other coronaviruses infections and the discovery of these molecular mechanisms may be important for designing new therapeutic approaches.

New Undergraduate Engineering Science Program Approved

Technology is central to our society. Universities play a key role as innovation hubs in new technology development, by linking knowledge creation, workforce development and commerce. After a multi-year planning process with Brandeis stakeholders and Engineering education experts, the Brandeis Faculty and Board of Trustees has approved the creation of a distinctively Brandeisian undergraduate Engineering Science program, designed for ABET accreditation. Unlike other models in which Engineers are siloed in their own department or school, this interdepartmental program is designed to  maximize horizontal integration across and beyond the Sciences.  All hands are now on deck to make this program a reality.  Institutional Advancement is working closely with faculty to raise the funds necessary to meet our ambitious goals.

Science Engineering LogoTo build up this program, we will  capitalize on the existing synergy between the life and physical sciences, while enhancing core research areas with an emphasis on translating basic research to technological applications.  Our goal is to integrate the engineering curriculum with the social justice mission that is integral to Brandeis. We envision providing opportunities for our students and faculty to deeply engage in science, design, and problem-solving while participating in a curriculum and culture that grapples with issues of social justice, business ethics and sustainability. The curriculum will be designed with these aspirations by engaging faculty from all of arts and sciences, IBS and Heller.  Ultimately, we hope that this new program will give our students the tools to intervene in the world and challenge them to build a better one.

We welcome input from our friends and alums as we begin to engage in the task of building up this exciting new program.

Summer Research Program back to (nearly) normal in 2021

SciFest 2019With increasing vaccination rates and declining positive Covid test rates, the Division of Science is looking forward to a vibrant, in-person summer undergraduate research program kicking off right after Memorial Day. 

The Division of Science summer program pairs first-hand research, community building, and guidance from Brandeis graduate students and postdoctoral fellows to provide undergraduate students a high-quality research experience. Past summer undergraduates have gone on to make substantial contributions (even as first authors!) to peer-reviewed research publications in fields such as materials chemistry (Shi et al., “Sunlight-activated phase change materials for controlled heat storage and triggered release”), molecular biology (Lamper et al., “A phosphorylation-regulated eIF3d translation switch mediates cellular adaptation to metabolic stress”) and neuroscience (He et al., “Rapid adaptation to Elevated Extracellular Potassium in the Pyloric Circuit of the Crab, Cancer borealis).

For Summer 2021, we are excited to announce that 58 Brandeis undergraduate researchers will be supported through the Division of Science programs and funding sources including NSF, NIH, and generous Brandeis alumni and foundation donors.

Additionally, the MRSEC Research Experience for Undergraduates (REU) program will support 6 undergraduate students from Hampton University for a 10-week, hands-on research program that runs in parallel with the MRSEC Summer Materials Undergraduate Research Fellowship. REU participants are mentored by MRSEC graduate students and postdoctoral fellows and contribute to materials science research efforts on Brandeis’s campus.

We will conclude the summer with SciFest, our annual summer poster session showcasing undergraduate research in the sciences, on August 5. Check the SciFest website for updates about the time and details for the session. 

Congratulations to all fellowship recipients!
