The Impacts Of Psychological Stress On Innate-Like Invariant T Cell Survival, Phenotype, And Function, Patrick Rudak
The Impacts Of Psychological Stress On Innate-Like Invariant T Cell Survival, Phenotype, And Function, Patrick Rudak
Electronic Thesis and Dissertation Repository
The nervous system serves numerous critical roles in the regulation of immune responses. Consequently, psychological stress can result in immunosuppressive states that are conducive to the development of infection and cancer. Yet, whether stress impacts the functions of innate-like T lymphocytes including invariant natural killer T (iNKT) and mucosa-associated invariant T (MAIT) cells, which participate in early host defense against pathogens and tumors, remains poorly understood. In this thesis, I leveraged multiple established methods with which to induce psychological stress in mice. I demonstrate that TH1- and TH2-type immune responses initiated by iNKT …

Ricin is a highly lethal protein toxin derived from the seeds of the castor plant, Ricinus communis. It is a Type II ribosome inactivating protein (RIP), meaning it is a heterodimer with one subunit, ricin toxin B (RTB), that mediates cell surface attachment and intracellular trafficking and a second subunit, ricin toxin A (RTA), that irreversibly shuts down protein synthesis in the cytosol. During trafficking, RTA and RTB necessarily separate in the endoplasmic reticulum, wherein RTA unfolds and translocates into the cytosol where it refolds into an enzymatically active conformation. RTA is remarkably fast acting and efficient, with few molecules …
