New method explores how mitochondrial tRNA changes can reshape immune cell behavior
For generations, scientists have looked to the genetics inside immune cells for ways to improve how the body fights disease.
A team of researchers from the University of Central Florida led by assistant professor Hung Nguyen is exploring how altering mitochondrial transfer RNA (tRNA) within T cells could influence the behavior of immune cells. This discovery could potentially lead to new treatments for cancer, infections, and autoimmune disorders. T cells are essential for identifying and eliminating foreign substances, including cancerous cells, and for remembering past infections to mount faster responses upon re-exposure.
Nguyen and his team, including Ph.D. candidate Cuong Pham, have identified that modifying tRNA in T cells could potentially fine-tune immune responses. This study marks the first time scientists have examined tRNA modification in T cells, an area previously unexplored. The research was conducted using advanced liquid chromatography-tandem mass spectrometry (LC-MS/MS) technology, which allowed the UCF team to detect and analyze these modifications.
The findings suggest that manipulating tRNA in T cells could help activate these cells to target specific disease cells, such as melanoma, colon cancer, and lupus. However, more research is needed to fully understand the underlying mechanisms and to validate these findings for potential therapeutic applications.
