Dr. Carson receives R03 grant to conduct research on A-particles in enterovirus infection of a cell.
Enteroviruses, including coxsackievirus, have been shown to decay to non-infectious forms, and the process is both temperature and time dependent. The capsids of these viruses explore multiple conformations (called capsid breathing), including a metastable low energy closed state, a transient open state, and a metastable non-infectious state called the A-particle. The receptor for coxsackieviruses (CAR) that enables viral infection of cells catalyzes the transition to A-particle. CAR binding to the closed conformation is lower affinity than is binding to the open conformation (per studies of related viruses). This difference establishes the conditions for an allosteric (cooperative) mechanism of receptor action on virus. Steven Carson, Ph.D. has proposed kinetic models that describe the interactions of CAR with coxsackievirus B3 (CVB3). The research funded by the R03 will interrogate the catalytic effect of soluble CAR on CVB3 strains that differ by single capsid amino acids and have stabilities at 37C ranging from a half-life of 7 hr (wild type) to 17 hr ( a selected stable mutant).
Dr. Kielian receives new 5-year R01 to identify how S. aureus biofilms alter innate immune responses in the brain during craniotomy-asssociated infection.
Neurosurgery to relieve life-threatening edema following traumatic brain surgery or stroke (decompressive craniectomy) or gain temporary access to the brain for tumor resection or epilepsy (craniotomy) requires removal of a portion of the skull (i.e. bone flap). The incidence of infection after craniotomy/craniectomy ranges from 0.8-12%, with a significant number caused by methicillinresistant S. aureus (MRSA), which forms a biofilm on both surfaces of the bone flap. Dr. Kielian’s laboratory has developed a mouse model of S. aureus craniotomy-associated biofilm infection that shares important ultrastructural and MRI attributes with human disease, which they will utilize to identify mechanisms for infection persistence. Translational research will also be performed in collaboration with UNMC neurosurgeons by immunophenotyping leukocytes from patients with craniotomy infections by RNA-Seq and metabolomics.
Dr. Reid receives R21 grant for research involving chikungunya virus infection.
St. Patrick Reid, Ph.D. has received a R21 grant for his submission entitled "Modeling Chronic Chikungunya Virus Infection in a vascularized Bone Model". The research outlined in the grant seeks to explore and elcuidate the mechanisms underlying the bone pathology observed during chikungunya virus (CHIKV) infection. Additionally, Dr. Reid's lab aims to address the contribution of the observed pathology to CHIKV-induced arthritis, a hallmark of infection.
Dr. Sun receives R21 grant for research on how SOCS1 protein exacerbates subsequent baterial infection.
Keer Sun, Ph.D. has received a R21 grant to conduct research on how SOCS1 protein, a feedback inhibitor of cytokine signaling, exacerbates subsequent bacterial infection. A frequent sequela of influenza infection is secondary bacterial pneumonia. Even with currently available antibiotics, bacterial pneumonia is a significant cause of morbidity and mortality in influenza pandemics and epidemics. The results of Dr. Sun’s investigation will provide the basis for identifying novel therapeutic targets for prevention of these infectious disease in humans.

Dr. Ouellette receives funding from National Science Foundation.
Scot Ouellette, PhD received $390,000 from the Molecular and Cellular Bioscience Division of the National Science Foundation to study the underlying changes in gene expression of bacterial pathogens in response to starvation conditions. This project will also focus on using several strategies to increase participation by American Indian students in college-level STEM research.
Department's transitioning to virtual microscopy brings opportunity to Nebraska high schools.
“Out with the old, in with the new” is a thought one may ponder when discussing new and exciting things. However, Nebraska high schools taking part in a Nebraska Department of Education (NDOE) curriculum on exploring laboratory medicine as a career, may not fully be aware of the newest
opportunity available to them. Faculty within the Department of Pathology & Microbiology recently saw a prospect to help expand a teaching opportunity while changing another. Due to transitioning from physical glass slides to virtual microscopy for teaching medical students histology and pathology within the College of Medicine at UNMC, microscopes, pathology and microbiology slides, and other laboratory supplies were no longer being utilized.
Dr. Peter Iwen, Director to the Nebraska Public Health Laboratory, heard about these available resources and made sure they were put to good use. Dr. Iwen met with Department of Pathology and Microbiology’s Chair, Dr. Steven Hinrichs, and Vice Chair of Medical Education, Dr. Geoffrey Talmon. Together the three brainstormed ideas that soon developed into a wonderful opportunity for high school students in Nebraska.
With ideas compiled, UNMC staff collaborated with the NDOE Health Sciences Coordinator, Carol Ringenberg Packard, to develop a means to utilize these resources. According to Packard, the NDOE will be hosting an annual Career and Technical Education conference in June for Nebraska teachers in Kearney which will include a session promoting a new course that explores laboratory medicine as a career, providing schools with new state standards for the Laboratory Medicine program. The NDOE will be advertising this session to both private and public school teachers around Nebraska. Seats will be available to teachers who are or plan to teach the coursework in their schools. It will also provide teachers with a microscope and other tools they can bring back to their schools to help enhance their teaching activities.
Dr. Geoffery Talmon, Vice Chair for Medical Education and Associate Professor for the Pathology and Microbiology Department states "Although the microscopes are older, the optics for these generally do not change over the years. We are hopeful visualization of the 'unseen' world will stimulate students in the sciences."

Dr. Cox invents in response to staff needs
Dr. Jesse Cox, current Chief Resident within our department, has developed a 3D-Printed Microscope Smartphone Mount. After hearing staff members were struggling using their iPhones to assist each other with a frozen section off campus, Dr. Cox designed a device to position a smartphone, quickly and easily, to an eyepiece to capture photos and video. While current available devices do exist to perform similar functions, most are cumbersome and/or expensive. Using 3D printing resources available on campus, multiple prototypes were developed, ultimately landing upon a design both universal and easy to use. As part of his experience, Dr. Cox spoke and worked with area high school students involved in club organizations through their high schools regarding the design, development and prototyping process through DoSpace and the UNMC Makers' Invent-a-thon Contest held in the spring. Dr. Cox launched Yellow Basement Design to sell his devices to a larger market.
