Derrick Samuelson, PhD - LSUHSC
Mentors: Judd Shellito MD and Alistair Ramsay, PhD

Alcohol Use and Susceptibility to Bacterial Pneumonia

Dr. Derrick Samuelson is a post-doctoral fellow at Louisiana State University Health Science Center in the Department of Medicine. Dr. Samuelson earned his PhD in Molecular Biosciences and Microbiology at Washington State University in 2013. His research was focused on hos-pathogen interactions and cellular signaling, specifically the pathogen Campylobacter jejuni. After completing his PhD, Dr. Samuelson started his post-doctoral fellowship at LSUHSC and started working on the development of a live oral vaccine against Pneumocystis pneumonia and understanding the influences of the intestinal microbiota on pulmonary infection and immunity in immunocompromised individuals.

As a Meritorious Post-doctoral Scholar, Dr. Samuelson will determine if alcohol-induced changes influence the intestinal microbial community. Using an alcohol animal model, he will determine the effects of alcohol consumption on the gastrointestinal, oral, and respiratory microbial tract and pathogen clearance. Specifically, his goal is to evaluate the role of ethanol in pulmonary immune responses and susceptibility to Klebsiella pneumonia. From these findings, Dr. Samuelson hopes to describe the role of alcohol-related immune defects and its influence in patient’s predisposition to respiratory bacterial pneumonia.

Elizabeth Martin, PhD - Tulane
Mentors: Bridgette M. Collins-Burow, MD, PhD and Jeffrey M. Gimble, MD, PhD

Decellularized Breast Cancer Extracellular Matrix in the Induction of Tumor Metastatic Recurrence

Dr. Elizabeth C. Martin is a post-doctoral fellow at Tulane University in the Department of Medicine. Dr. Martin completed her PhD in Biomedical Research at Tulane University in New Orleans, LA in 2013. Her dissertation focus was the evaluation of the effects of microRNAs, specifically miR-155, on estrogen receptor positive breast cancer cell biology with a focus on estrogen receptor signaling. Following her PhD, Dr. Martin joined the Center for Stem Cell Research and Regenerative Medicine at Tulane University where she used proteomic analysis of patient serum to detect potential prognostic markers and activated pathways involved in the development of heterotopic ossification.

During the LA CaTS Meritorious Post-doctoral Scholarship, Dr. Martin will evaluate breast cancer-derived extracellular matrix as an avenue for tumor recurrence under the guidance of Dr. Bridgette Collins-Burow. It is believed that the tumor microenvironment can support cancer stem cells and maintain stemness. Following primary therapy, residual matrix may remain at the sites of metastasis and instigate signaling to cancer stem cells which can then re-propagate the metastatic lesion. Given the different extracellular matrix compositions of breast carcinomas and normal tissue, the extracellular matrix may act as a pro-tumorigenic agent. The identification and characterization of the tumor extracellular matrix, will lead to novel methods for intervention. Therapeutically-driven alterations to the extracellular matrix may prevent recurrence of breast carcinomas through the removal of a permissible microenvironment.
