MCB 2021 Departmental Retreat

August 30, 2021

MCB held a Departmental Retreat on Thursday, August 26th. After welcoming remarks, the 2021 MCB graduate awards were announced.


Following a ‘Get to Know the New Students’ event, new faculty member, Assistant Professor, Jelena Erceg presented a talk, “Genome Folding and Regulation in Diploid Multicellular Organisms”

A fun trivia session preceded the Lab Poster Sessions. The virtual event was held on a fun, new platform called SpacialChat that split the presentations into 5 different poster rooms allowing attendees to circulate among the rooms. The retreat finished with a Social Mixer with Happy hour rooms. Screen shots of the event can be found here.

UConn Virus Expert and MCB Professor Carol Teschke Awarded Fulbright Scholarship to Study in the UK

August 4, 2021

Teschke will spend four months at the University of York studying the geometry and evolution of a type of virus that could help develop antivirals. Story in UConn Today, Amanda Song, CLAS

Carolyn Teschke, professor and department head of molecular and cell biology at UConn, has been awarded a Fulbright Scholar Award to study virus assembly and evolution at the University of York, in the United Kingdom.  

Teschke applied for the scholarship after talking with colleagues at the University of York for months about a collaborative project working on the process of virus assembly. The Fulbright, which is awarded by the U.S. State Department and international sponsors, will allow her to conduct research in the U.K. for four months. 

“I am so pleased and excited to receive this prestigious award to study in the U.K.,” says Teschke. “My hosts at the University of York, Professors Riedun Twarock, a mathematician who studies virus architecture, and Fred Antson, who studies large bacteriophages, will work with me to mathematically model how viruses assemble using experimental data generated in my lab.” 

Teschke’s research focuses on understanding how a virus puts itself together inside an infected cell. Using a model system of bacteriophage P22, a well-known type of virus that infects bacteria, Teschke’s lab group models how a herpes virus would attack, assemble, and replicate inside a human cell. 

“Rather than studying a herpes virus, growing cell cultures and risking getting infected, we use this simple model system,” Teschke says. “If we understand how our model system works, hopefully that information will assist scientists that study herpes viruses and help them develop antivirals.” 

An antiviral for the herpes virus might prevent it from replicating once it attacks a cell, thus reducing the chances of someone getting sick.  

Teschke hopes to use her lab’s data and Twarock’s mathematics expertise in the geometry of  virus capsids, or its outer protein-based shell, to understand on a more detailed level how the different proteins of P22 assemble.  

“It’s almost like a dance, the way the virus proteins have to come together in a specific order, with a particular affinity, or tightness, to make the capsid,” Teschke says. “If we have an idea how tight the interaction between the proteins must be, we can make an antiviral that interrupts that process in the early stages.” 

By collaborating with Antson, Teschke hopes to understand how a virus evolves to grow bigger over time, and whether she can change the proteins in her model virus to become bigger, like the ones Antson works with. This would help her understand the process of virus evolution, where a virus accumulates mutations that affect the viral capsid geometry.

UConn Researcher Working to Uncover Key to Cellular Mechanisms in Parasite – Aoife Heaslip Receives Grant

UConn Researcher Working to Uncover Key to Cellular Mechanisms in Parasite

Aoife Heaslip has received a grant to study the molecular underpinnings of a parasite that can cause severe infections in people who are immunocompromised and babies.

Toxoplasmosis is a common but usually non-life-threatening parasitic infection linked to contaminated food or water. While most people infected by Toxoplasma gondii (T. gondii), the parasite responsible for toxoplasmosis, will have very mild or no symptoms at all, the parasite can persist in the body for long periods of time, possibly even an entire lifetime.

People who are immunocompromised and babies, if infection occurs in utero, can suffer severe symptoms. If a person’s immune system cannot combat the infection, it may cause damage to the brain, eyes, or other organs. T. gondii is a leading cause of congenital neurological defects.

University of Connecticut assistant professor of molecular and cell biology Aoife Heaslip has received a $2 million grant from the National Institute of General Medical Sciences to study molecular functions of T. gondii. Heaslip hopes this work will provide a better understanding of how this parasite operates and thus pave the way for new therapeutic approaches.

Heaslip will focus on T. gondii’s intracellular cargo transport mechanism. This process involves the movement of vesicles — cellular transport containers for materials like proteins — within a cell. Intracellular transport and vesicle secretion are essential cellular functions for all eukaryotes. For T. gondii, they are key to this pathogens ability to invade and grow within its host’s cells.

Despite its importance, to date, scientists have only studied cargo transport mechanisms in a small number of model species leaving wide knowledge gaps about how other eukaryotes, like T. gondii, complete this task.

The goal of Heaslip’s lab is to uncover the cargo transport mechanism in T. gondii. Their previously published data show there are two proteins: actin and unconventional myosin (MyoF), required for intracellular cargo transport in T. gondii. Both proteins are part of the T. gondii’s cytoskeleton, the part of the cell responsible for maintaining cell shape and locomotion.

Heaslip’s lab will utilize an interdisciplinary combination of approaches including parasite genetics and cell biology, live cell imaging and quantitative vesicle tracking, and in-vitro biophysical approaches to answer these questions.

“My laboratory occupies a unique niche at the intersection between parasitology and molecular motors fields,” Heaslip says. “Utilizing these interdisciplinary approaches makes us ideally positioned to provide new insights into this understudied process.”

Heaslip will work to understand how the cells regulate MyoF activity and how cargo packaged in vesicles interact with the actin cytoskeleton. She will also identify if there are additional molecular plays required for cargo transport and how they work with actin and MyoF to accomplish this task.

This work is relevant beyond toxoplasmosis as T. gondii is closely related to parasites that cause malaria and life-threatening diarrheal diseases. Understanding T. gondii’s transport mechanism will also provide insights into these parasites.

By understanding how a parasite like T. gondii completes cargo transport functions, scientists can leverage that knowledge to develop ways to interrupt this process with drugs that would kill the parasite.

Heaslip holds a Ph.D. from the University of Vermont. She completed postdoctoral training at Indiana University, Bloomington and the University of Vermont. Her research focuses on understanding the biology of T. gondii using interdisciplinary methods to elucidate the molecular mechanisms underlying essential processes for this parasite to identify new drug targets.
