Immature cd8 single-positive thymocytes
Witryna1 lip 2024 · Further differentiation to the immature single-positive (ISP) stage is accompanied by cell surface expression of CD8. The transition of the ISP to the double-positive (DP), CD4 + CD8 + thymocytes, requires a single round of cell cycle, leading to surface expression of both CD4 and TCRαβ (Yu et al., 2004).
