What is a misconception regarding generating Treg cells by overexpressing FOXP3 in a Th17 cell?
What is a misconception regarding generating Treg cells by overexpressing FOXP3 in a Th17 cell?
- It is a successful method for inducing Treg cells.
- It leads to the direct conversion of Th17 cells into Treg cells. (correct)
- It bypasses the requirement for specific transcription factors for Treg cell generation.
- It is an ineffective method due to the need for additional transcription factors.
