BBB pathology and pharmacology

BBB functions in physiological and pathological conditions

- modelling BBB changes in prion diseases, Alzheimer disease and other pathologis

- role of histamine in the regulation of BBB functions

- protection of the BBB in pathological conditions by therapeutical molecules eg. pentosan

Drug targeting to brain

- circumventing the BBB by nasal application of drugs: role of mucoadhesive properties in formulations

- construction of niosomes (nanoparticles made from nonionic surfactants) that target transport systems at the BBB to deliver therapeutical molecules to brain

and Optics; Quantum Electronics, University of Szeged)



Nasal pathway

- modelling the nasal epithelium for drug transport studies, comparison with other barriers

-testing different formulations for effective nasal transport of active ingredients to the systemic circulation
