Hawiger Group Reveals the Formation of Autoimmune Effector Precursors
Daniel Hawiger, Ph.D., Associate Professor of Molecular Microbiology & Immunology, will publish a paper in Cell Reports detailing his group’s studies on the pathogenesis of autoimmune diseases. Two Postdoctoral Fellows, Adeleye Opejin, Ph.D., and Alexey Surnov, Ph.D., are co-authors on the publication.
The group’s research revealed a two-step process in the formation of self-reactive effector T cells, which are the key type of immune cells with potential autoimmune functions. The process starts with induction of effector precursors that express a transcription co-factor, Homeodomain only protein (Hopx). The precursors are then imprinted with multiple instructions for their subsequent terminal effector differentiation and autoimmune functions. This research may lead to new ways of blocking the autoimmune process in its early stages and could help modulate the course of more advanced autoimmune disease.
McCommis Lab Finds Diet May Reverse Heart Failure
Kyle McCommis, Ph.D., Assistant Professor of Biochemistry, recently published a paper in Nature Metabolism showing that a high fat, “ketogenic” diet could prevent or reverse heart failure caused by impaired cardiac flexibility. Using a mouse model with a genetic deletion of mitochondrial pyruvate carrier (MPC), the researchers found that a high fat/low carbohydrate (ketogenic) diet reversed or prevented heart failure in these mice. Similar results were found after a 24-hour fast or with a high fat, non-ketogenic diet.
These results indicate a important role for MPC deficiency in cardiac dysfunction and dietary manipulations that can prevent or reverse cardiomyopathy in mice and, potentially, in humans. Read the full story in Newslink.
DiPaolo Group Publishes New Findings On Stomach Cancer
Richard DiPaolo, Ph.D., Professor of Molecular Microbiology & Immunology, published a paper in Gastronenterology detailing his group’s studies on chronic inflammation and its role in gastric cancer. The study was led by SLU M.D./Ph.D. student, Kevin Bockerstett, working closely with a SLU student in Computer Science Master’s Program, Scott Lewis. The group used a new technology, single cell RNA sequencing, to identify new cell types and new biomarkers during the early stages of cancer development. Studies were performed in mouse models of gastric cancer, and findings were confirmed in human tissue biopsies. This study provides important insight into the early steps in gastric cancer development.
SLU Enrolls Participants in Phase III Vaccine Trial
The SLU Center for Vaccine Development began enrolling participants in a phase III trail to determine the effectiveness of a COVID-19 vaccine, which was co-developed by Moderna and the NIAID Vaccine Research Center. The vaccine will be tested in adults 18 years and older. Approximately 30,000 participants across the country will be test in this phase of the trial. If you are interested in participating in the vaccine trial, see the SLU Vaccine Center website for full info. Read the full story in Newslink.
