Editor Comments:  
 
A point -by-point response letter must accompany your re vised manuscript. This letter must

Reviewer reports:  
 
Lucas Souto Nacif, PhD (Reviewer 1): Acceptable corrections and manuscript imporvements  
Thank the reviewer for your suggestions.  
 
Reviewer 2 (Reviewer 2): GENERAL COMMENTS: The authors replied to all the reviewers' 
comments and requests.  
 
 
 
REQUESTED REVISI ONS:  
 
However, some requests have not been fulfilled  
 
1 display of isotype control in Fig.4;  
 
Thank the reviewer for your suggestion, we listed the isotype control in the last responsiveness 
letter as below, since most of paper did not use the isotype cont rol in final figure, and it will not 
be well rearranged, I can list isotype control as supplement data if you agree with it.  
 
 
 
2 partial clarification on the limitations of the study in the Conclusion session).  
Thank the reviewer for your suggestion, we add the limitation in Conclusion session, see line 
389 
 
3 Limitation in analysis of hepatic metabolic enzymes, such as Cyp2C or Cyp3A1 raised by 
reviewer #2, has not been stated while should be properly addressed in Conclusion session and 
clearly stated if object of ongoing studies.   
Thank the reviewer for your suggestion. Although we select CYP3A2 as enzyme involved in 
tacrolimus metabolism was based on a couple of manuscripts (refs 29 and 30), the most abundant 
CYP subfamily (in rat liver) is the CYP2C, which has a role closer to human CYP3A enzymes, 
we list that as this study’s limitation, and will further check it in ongoing study, see line 393  
 
4 The authors agree with reviewer's suggestion to re -arrange Resul ts section. However Figures 
need to be rearrange as well (i.e., lung/kidney histological analysis should be moved in a separate 
Figure or described earlier in the text).  
Thank the reviewer for your suggestion, lung/kidney histological analysis is describe d earlier in 
the text, see line 217  
 
5 Similar comment for figure 3 (apoptosis is described at page 12 while alphabetaTCR at page 
10, but both represented in the same Figure).  
Thank you for your suggestion, alphabetaTCR and apoptosis is described at same page, see line 
231 
 
6 Figure Legends contain large amount of result description. Such sentences should be moved in 
Results, limiting the long text in Legends. Once again, several Figure contains one panel only, 
resulting in large number of figures (8). Sev eral Figures can be rearranged and grouped. Several 
mistypos are still present in the text (i.e. kedney instead of kidney in Figure 2)  
Thank the review for your suggestions, we shortened the figure legends. We also combine the 
figure 5 and figure 7, and c orrect the mistypos.  
 
 
 
ADDITIONAL REQUESTS/SUGGESTIONS:
