Generation and Treatment of Antibiotic Resistance

Antibiotics are responsible for the most significant increase in lifespan in human history. However, microbes are becoming resistant to antibiotics at an alarming rate. The Mulvey lab found that microbes within a single colonized site, such as the human bladder, can pass antibiotic resistance genes back and forth, propagating resistance as the infecting microbes evolve in response to serial antibiotic treatment.

Commensal Microbes That Help Prevent Metabolic Disease

Our intestines are colonized by a vast consortium of bacteria, viruses, and fungi that we now know have essential influences on gut health. Research in the Round lab has recently shown that intestinal antibody responses select for specific organisms within the gut that prevent metabolic disease by limiting fat absorption within the intestine.

MicroRNA Regulation of Inflammation and Immunity

MicroRNAs provide a crucial level of control for cell development and function through their post-transcriptional regulation of gene expression. Their importance is highlighted by their diverse functions in a range of cell types, including immune cells. Continue reading → MicroRNA Regulation of Inflammation and Immunity

Vascular Inflammation in Malaria Pathogenesis

The pathogenesis of malaria is characterized by vascular inflammation exacerbated by immune cells that travel to areas where red blood cells infected with parasites stick to the endothelium lining the blood vessels. The Lamb lab has made significant discoveries demonstrating a key role for receptor tyrosine kinase family Eph receptors in malaria pathogenesis.

Rapid Identification of Microbial Pathogens

The rapid identification of microbial pathogens is critical for timely and successful treatments. Improved capabilities in pathogen identification were the focus of a collaboration between physicians and scientists in the departments of Biomedical Informatics, Human Genetics, and Pathology.
