Glycerol Monolaurate (GML) is a nontoxic natural compound that has significant antibacterial and antiviral activities. The drug has been approved by the Food and Drug Administration (FDA) for its potency against gram positive cocci and Bacillus anthracis. A possible mechanism of action of GML is the interference of plasma membrane and subsequent bacterial protein signaling. GML is also virucidal against many enveloped viruses by interfering with viral fusion to mammalian cells. My project focuses on the finding that GML has been shown to inhibit T lymphocyte proliferation in the context of superantigen induced toxic shock syndrome. Inositol phosphate 3 (IP3) levels have been shown to decrease following GML administration. This finding suggests that GML is inhibiting T cell proliferation through intracellular mechanisms. The goal of my project is to characterize the molecular signaling mechanism of how GML inhibits T lymphocyte proliferation.
