  • To deliver a large panel of mouse model developed in-house or customized

VibioSphen Missions

  • To give an answer to a major issue of public health : antibiotic resistance
  • In-house predictive and customized in vivo pharmaceutical models in infectious diseases and inflammation provides to pharmaceutical industries, Biotechnology Companies and all other private or academic institutes preclinical solutions to evaluate compounds

Our strategies

  • Boosting innate immune system
  • Repositioning molecules in our study area : immunomodulation in infectious diseases
