1. ATP-Binding-Cassette Transporters in Biliary Efflux and Drug-Induced Liver Injury
Abstract : Membrane transport proteins are known to influence the absorption, distribution, metabolism, excretion and toxicity (ADMET) of drugs. At the onset of this thesis work, only a few structure-activity models, in general describing P-glycoprotein (Pgp/ABCB1) interactions, were developed using small datasets with little structural diversity.

2. Interindividual Variability of Drug Transport Proteins : Focus on Intestinal Pgp (ABCB1) and BCRP (ABCG2)
Abstract : The appearance of adverse drug reactions is a common reason for hospitalization in Western countries. Research on underlying biological mechanisms for interindividual variability in drug response aims to better identify patients with exceptional genetic traits, disease conditions or risk of drug-drug interactions and thereby help to prevent adverse drug reactions.

3. Intestinal barriers to oral drug absorption: Cytochrome P450 3A and ABC-transport proteins
Abstract : The subject of this thesis was to study two intestinal barriers to oral drug bioavailability, drug efflux proteins of the ABC-transporter family, and in particular ABCB1/P-glycoprotein (Pgp), and the drug metabolizing enzyme cytochrome P450 (CYP) 3A4. At the onset of this thesis, similarities between CYP3A4 and Pgp in terms of their tissue distribution and gene regulation, along with overlapping substrate specificities, had generated the hypothesis that CYP3A4 and Pgp may have a complementary function and thus form a coordinated intestinal barrier to drug absorption and gut wall metabolism.

4. Drug Transport and Metabolism in Rat and Human Intestine
Abstract : One of the aims of this thesis was to investigate the involvement of efflux proteins, such as the P-glycoprotein (Pgp), in the drug transport in different regions of the rat and the human intestine. The intestinal extrusion of intracellularly formed CYP3A4 metabolites, including whether this extrusion might be mediated by Pgp, was also studied. READ MORE

5. Evaluation of macrocyclic lactone resistance in gastrointestinal nematodes of first season grazing cattle
Abstract : Parasitic gastrointestinal nematodes (GIN) are common world-wide among grazing cattle, and cause welfare problems and associated economic losses due to reduced performance of their hosts. In Sweden, the most important GIN include Cooperia oncophora and the more pathogenic Ostertagia ostertagi, which are usually present as mixed infections in first season grazing cattle (FSG). READ MORE
