title: NLRs Challenge Impacts Tight Junction Claudins In Sertoli Cells.
abstract: The present study aims to investigate the NALP3 system and its effect on claudins in Sertoli cells using a mouse adult Sertoli cell line as a model. We focus on the Sertoli cell biology looking for the possible implications for male reproductive functions.
  
  
  
  Adult Sertoli cells were transfected with NAPL3 siRNA and treated with NOD1 (ie-DAP) and NOD2 (MDP) receptor ligands. Two dimensional gel electrophoresis was performed on lysates of non-challenged and MDP-treated Sertoli cells.
  
  
  
  There were positive claudin-5 and claudin-11 expression levels on transcript (RT-qPCR) levels. Specific protein spots in 2D gels were detected after bioinformatics analysis. This study demonstrates direct induction of tight-junction proteins probably favouring junction stability.
  
  
  
  The innate immunity and tight-junction pathway integration probably have a protective role for both blood-testis immune barrier and spermatogenesis compartmentalisation maintained by the very same barrier. This integration also points the way for mechanistic research of the disturbances inflicted during an inflammatory response in the testis niche.
