Autophagy as a survival strategy for CD8+ memory T cells
Zusammenfassung der Projektergebnisse
During my postdoctoral fellowship I could identify autophagy as an essential process that effector CD8+ T cells need to live. To our knowledge, this is the first project that explores the role of autophagy in CD8+ T cells during immune responses in vivo. CD8+ T cells are one component of the adaptive immune response that clears the body of infections or tumors. Knowing which processes these cells need for their maintenance and survival is of importance for research that aims to positively influence CD8+ T cell immune responses. It is furthermore important for considerations of detrimental side effects of drugs. For example, autophagy is one mechanism that tumor cells use to sustain their viability under conditions of low nutrient or oxygen conditions. Several autophagy suppressing drugs are currently in development to target tumor cells. The knowledge that autophagy is an essential process for effector CD8+ T cells is important for drug development for tumor treatments, as CD8+ T cell mediated tumor cell killing is one element of successful tumor eradication.
