31. Activation mechanisms of Class F receptors
Sammanfattning : Our genetic makeup is composed of thousands of genes that code for the proteins involved in all aspects of cellular function. Proteins are molecular machines that dynamically and structurally respond to stimuli. LÄS MER
32. Cellular receptors for species B adenoviruses
Sammanfattning : Adenoviruses belong to the most common human pathogens. The severity of infection varies greatly, from subclinical to lethal, depending on the virus type and immune status of the infected host. The 51 known human adenovirus serotypes are divided into six species (A-F) based on characteristics such as tropism. LÄS MER
33. One key to two doors : Dual targeting peptides and membrane mimetics
Sammanfattning : A targeting peptide at the N-terminus of a precursor protein usually directs the protein synthesized in the cytosol to a specific organelle in the cell. Interestingly, some targeting peptides, so-called dual targeting peptides (dTPs) can target their protein to both mitochondria and chloroplasts. LÄS MER
34. Adenosine A2A and ATP receptors in PC12 cells
Sammanfattning : PC12 cells, originally isolated from a rat pheochromocytoma, are widely used to study receptor pharmacology and nerve cell differentiation. They are the neoplastic counterpart of adrenal chromaffin cells, but upon treatment with NGF they acquire a neuronal phenotype. LÄS MER
35. Biophysical studies of cell membrane receptors for the growth factors PDGP and EGF : Aspects on lateral and aggregation
Sammanfattning : When extracellular growth factors bind to their specific cell surface receptors, they elicit a cascade of biochemical events, including tyrosine kinase-mediated phosphorylation and changes in intracellular free ca2+, leading to cell differentiation and proliferation. However, direct effects of ligand-binding on the receptors are poorly understood. LÄS MER
