Aquaporin-4 as a molecular partner of cystic fibrosis transmembrane conductance regulator in rat Sertoli cells

Our results suggest that CFTR physically interacts with AQP4 in rat SCs evidencing a possible mechanism by which CFTR can control water transport through BTB. The full enlightenment of this particular relation between CFTR and AQP4 may point towards possible therapeutic targets to counteract male subfertility/infertility in men with Cystic Fibrosis and mutations in CFTR gene, which are known to impair spermatogenesis due to defective water transport.
