In the published article, there was an error in Figure 5 as published.
Figure 5.
Maturation of medullary thymic epithelial cells (mTECs) in wild-type (WT), Lig4 R/R, and Rag1 S/S mice. Mature mTECs from WT mice express claudin-4 (Cld4), Ulex europaeus agglutinin 1 (UEA-1) and Aire (upper panels). Insets highlight fully mature mTECs showing immunoreactivity (IR) for Cld4 and the characteristic granular dot-like Aire positivity in the nuclei. Thymuses from Lig4 R/R mice show residual presence of mTECs that reach full maturation with positivity for UEA-1, Cld4, and Aire expression (middle panels). Loss of corticomedullary demarcation (CMD) with impaired maturation of mTECs was observed in the thymuses from the Rag1 S/S mice in which only rare UEA-1 IR cells but no mature Cld4+ and Aire+ cells were found (lower panels). IR staining: brown. All panels are from 20× original magnification; insets are from 40× original magnification. One representative example of five mice analyzed per each strain.
“The insets within the right upper and middle panels showing a higher magnification of the AIRE immunostaining have been corrected. In the original panels, there was a mistake in placing the original insets from a higher magnification image.”
The corrected Figure 5 and its caption appear below.
