Temitayo T. Bamgbose

Cassidy M. Blackburn

B.A., Biology, 2016, DePauw University

Research:  Atherosclerosis is a hypercholesterolemia-induced inflammatory condition of arteries mediated by macrophages. Why macrophages become inflammatory in response to hypercholesterolemia is enigmatic. We have demonstrated that the glycerolipid synthetic enzyme lipin-1 in macrophages is atherogenic.  My project is to elucidate the molecular mechanisms by which macrophage-associated lipin-1 promotes atherogenesis.

Kellie N. Brown

B.S., Biology, 2015, University of Memphis

Research: Rotavirus causes gastroenteritis that can be life-threatening in children. The rotavirus nonstructural protein NSP1 inhibits the host immune response by promoting the degradation of proteins required for interferon production. NSP1 has been shown to interact with cullin RING ligases (CRLs), which are host ubiquitin ligase complexes. My research is investigating the NSP1-CRL interaction to determine if NSP1 is using this complex to induce degradation of host proteins or if the interaction has other roles in viral replication.

Anthony J. Domma

B.S., Louisiana State University, 2017

Research: This lab has found that HCMV protein UL148 induces quality control structures, and formation of these structures are PERK dependent. My project is to identify the protein-protein interactions that are crucial for the formation of these quality control structures. I will use tandem affinity purification and other methods in attempts to elucidate the molecular mechanism of how 148 induces stress and to answer if its effects on Endoplasmic Reticulum Associated Degradation (ERAD) are specific.

Joseph I. Eniafe

B.S., Microbiology, Obafemi Awolowo University, Nigeria, 2016

Heather Fulkerson 

B.S., Biology, 2014, University of Houston 

Research: Our lab has focused on understanding how Human Cytomegalovirus (HCMV) infection of monocytes promotes viral spread. We have demonstrated that binding of viral glycoproteins to cellular epidermal growth factor receptor (EGFR) and integrins drives a unique signalosome in monocytes, which initiates biological changes required for hematogenous dissemination. This signalosome facilitates viral entry and nuclear translocation in monocytes. My project seeks to determine how HCMV-induced signaling through EGFR and integrins directs viral trafficking to the nucleus of the infected monocyte.

Samantha K. Murphy

B.S., Biological Sciences, 2013, LSU Shreveport

M.S., Molecular & Cellular Biology, 2015, LSU Shreveport

Research: Rotavirus is the most common cause of gastroenteritis in young children and infants worldwide.  The virus inhibits the innate immune response by preventing the host from producing interferon. The goal of my project is to understand how the viral nonstructural protein NSP1 inhibits the interferon response by inducing degradation of host proteins.

Julia E. Myers

B.S., Biology, 2016, University of Central Arkansas

Research: Epstein-Barr virus (EBV) and human papillomavirus (HPV) are two viral infections commonly found worldwide. It has been previously shown by our lab that coinfection of HPV and EBV is present in oral squamous cell carcinomas (OSCC). Using an organotypic raft model system, we have found that the expression of HPV E7 inhibits EBV replication. The goal of my project is to investigate the mechanisms behind E7 inhibition of EBV replication.

Sadie Rice 

B.S., Microbiology, 2014, Oregon State University

Research: Human papillomaviruses regulate host and viral gene expression to create an environment in which the virus can persist and replicate. My project focuses on the viral oncoprotein E7 and its abilty associate with transcriptional regulators in chromatin to modify gene expression patterns. 

Danielle L. Schaal

B.S., Biology, Ouachita Baptist University, 2019

Research: New student

Robert. M. Schilke

B.S. (2014), M.S. (2017), University of North Carolina Wilmington

Research: Atherosclerosis is a hypercholesterolemia-induced inflammatory condition of arteries mediated by macrophages. We have demonstrated that lipin-1, a key enzyme in the glycerolipid synthesis pathway, regulates oxidized low-density lipoprotein-induced macrophage inflammatory response. Lipin-1 also has transcriptional co-regulatory activity and its contribution to atherosclerosis has yet to be elucidated. My project will seek to identify protein-protein interactions between lipin-1 in macrophages in response to oxLDL to provide insight into the regulation of lipin-1 activity that may contribute to atherogenesis.

Billy H. Ward, Jr. 

B.S. (2007), M.S. (2016), Mississippi State University

Research: Neisseria gonorrhoeae (Ng) is a human-adapted bacterial pathogen responsible for an estimated 80 million cases of sexually transmitted disease each year. Unable to survive outside the human host, Ng has evolved multiple strategies to promote persistence and growth by modulating host immune system functions.  Macrophages are critical mediators of the immune response and tissue homeostasis. The role of macrophages in Ng pathogenesis is poorly understood. Our laboratory has found that Ng exploits macrophages for survival and growth. We have shown Ng displays niche plasticity during macrophage infection, by colonizing and replicating on the cell surface or intracellularly. We also discovered that gonococci invade macrophages by a novel actin-dependent mechanism to establish a unique membrane-bound organelle. The goal of my research is to elucidate the mechanisms by which Ng colonizes the macrophage and to understand the role of this interaction in gonococcal pathogenesis.
