Synopys

Biological barriers are indispensable for the integrity and function of many human organs. Moreover, most of the times, bioactive compounds pharmacodynamics and pharmacokinetics are affected by their interaction with the physiological barriers. Indeed, bioactive compounds, drugs and nanoparticles need to cross biological barriers to reach their target and, in some cases, act at the barrier level. The course will explore the molecular structure and function of biological barriers such as skin, lung, gastrointestinal and blood brain barriers. The most used in vitro models for each one of these barriers will be discussed regarding their advantages and disadvantages, and the limitations regarding the translation to the human body.

The course will be composed by a theoretical and a significant hands-on component.


Learning outcomes

Upon completion of the course, the student should be able to:

  • Ÿ Describe the structure of biological barriers by considering their surface and colloidal chemical characteristics
  • Ÿ Explore the role of biological barriers on medicine, toxicology and drug delivery
  • Ÿ Relate the characteristics of biological barriers with adsorption, absorption, partition and diffusion phenomena at the barriers
  • Ÿ Recognize the importance of biological barriers models for clinical translation of new drugs and delivery systems
  • Ÿ Design appropriate strategies/assays with biological barriers models
  • Ÿ Execute protocols for the production of in vitro models of skin (using Franz cells), intestine and brain (using Transwell devices) and pulmonary surfactant (using Langmuir monolayers).
  • Ÿ Use the produced models to evaluate the interactions with bioactive compounds and nanoparticles.
