26. Rewiring ret : PTB-adaptor regulated signaling and cell biology
Sammanfattning : The Ret receptor belongs to a group of transmembrane tyrosine kinase receptors that serve to transduce environmental signals into cellular responses. Upon extracellular ligand activation the receptors dimerize and their structural conformation is altered into one that allows for interaction with proteins in the cell cytosol. LÄS MER
27. Helicobacter pylori : multitalented adaptation of binding properties
Sammanfattning : Helicobacter pylori infects and persistently colonizes the stomach, which results in gastritis and in some individuals peptic ulcer disease or gastric cancer. Adherence of H. pylori to the epithelium is an important factor for development of disease. LÄS MER
28. Translational studies of molecular interactions in Parkinson’s disease
Sammanfattning : Interactions between molecules are the basis of cellular function. In disease, these tightly regulated systems are often disturbed. Parkinson’s disease (PD) is recognized by protein aggregates in the brain of erroneously interacting molecules, directly linking the clinical picture to the molecular mechanisms. LÄS MER
29. Studies of cell signalling using bacterial toxins and organic electronic devices
Sammanfattning : One of the most versatile biological signalling entities is the calcium ion, Ca2+. With a characteristic spatial and temporal signalling pattern, this universal second-messenger directs diverse cellular functions, e.g. secretion of neurotransmitters at the synaptic cleft to regulation of transcription and fertilization.

30. Visualizing the dynamic interplay between the host and bacterial pathogen : a real-time study of renal infection
Sammanfattning : The human body is a complex entity capable of handling a variety of pathogenic challenges without developing disease symptoms. Sometimes, however, the pathogens are superior and the host immune system is unable to clear the infection. LÄS MER
