New findings that are relevant for the treatment of human diseases
New findings from researchers at the Department for Functional Cancer Genomics at the Vetmeduni Vienna, in cooperation with the Technical University of Denmark (DTU), provide insights into mechanisms of immune cells that could affect future therapies for human diseases. The study called “The neonatal microenvironment programs innate γδ T cells through the transcription factor STAT5“ includes the participation of member of Richard Moriggl’s group.
Our immune system contains specialized cells that act as the first answer against pathogens such as bacteria and viruses. These cells are called gamma-delta (γδ) T cells and are mainly found in organs such as the intestine, lungs, skin and lymph nodes. However, this specific T cells can also promote autoimmune and immune-related diseases such as psoriasis and multiple sclerosis. Understanding the basic biology of γδ T cells is essential in order to find ways to treat these diseases. In addition, by controlling the γδ T cells in a targeted manner, one could envision the use of these cells to fight infections and inflammations. This new study shows, for example, that STAT5 is necessary for the growth of certain types of γδ T cells during neonatal mouse life. Mice that do not express STAT5 do not produce these T cells and are resistant to multiple sclerosis. Furthermore, the authors describe a new type of γδ T cells that can only be found in the intestine. This new cell type has different functions than other types of γδ T cells and requires STAT5 for its growth. The results imply that the newly identified cell type is an important defence mechanism against intestinal infections shortly after birth. Therefore, manipulation of γδ T cells may help to strengthen immunity in early age.
