1. Cellular regulation of heparan sulfate structure and function
Abstract : Heparan sulfate (HS) is a sulfated glycosaminoglycan found on cell surfaces and in the extracellular matrix as HS proteoglycans. HS is synthesized as a polymer of alternating glucuronic acid and N-acetylglucosamine units. READ MORE

2. Structure-function relationships of hormone-sensitive lipase
Abstract : The primary role of hormone-sensitive lipase (HSL), an 84 kDa enzyme of 768 amino acids (in the rat protein), is to hydrolyse stored triacylglycerols in adipocytes of white adipose tissue. Catecholamines and insulin regulate lipolysis through cellular signalling. READ MORE

3. Asymmetric Cellular Microenvironments
Abstract : This thesis presents methods to combine 3D cell culture, microfluidics and gradients on a controlled cellular scale. 3D cultures in biological extracellular matrix gels or synthetic gels bridge the gap between organ-tissue cultures and traditional 2D cultures. READ MORE

4. Deciphering Carbohydrate Structure : From NMR Chemical Shifts to Conformational Analysis
Abstract : Carbohydrates are ubiquitous in nature and exhibit a multitude of roles. Besides nucleic and amino acids, they can be regarded as the third alphabet of life. They are used as energy source to fuel the cells, as structural building blocks and play a key role in cellular recognition processes. READ MORE

5. Structure, Mechanism, and Regulation of Sodium/Proton Exchangers
Abstract : Sodium/proton exchangers (NHEs) are secondary active transporters that are ubiquitously found in all kingdoms of life. They facilitate the exchange of protons for sodium ions or other inorganic ions across biological membranes, regulating pH, sodium levels, and osmotic pressure. READ MORE
