1. Expression and processing of cecropin and attacin using a baculovirus vector
Abstract : The cecropins and attacins are two antibacterial peptides induced uponimmunization in the moth Hyalophora cecropia. They are both synthesized aspreproproteins that are processed and post-translationally modified along the exportpathway. READ MORE

2. Studies on the structure and biogenesis of membrane proteins from the green alga Chlamydomonas reinhardtii
Abstract : The green alga unicellular Chlamydomonas reinhardtii has been used for many years as a model system in the area of photosynthesis. Therefore, the C. reinhardtii chloroplast has been the subject of many studies. In contrast, the mitochondria have received less attention. READ MORE

3. The amyloid-β precursor protein (APP) and its adaptor protein Fe65 : Two key players in Alzheimer’s disease
Abstract : Alzheimer’s disease (AD) is a neurodegenerative disease characterized by the abnormal accumulation and aggregation of amyloid beta (Aβ) peptides within the brain. Generation of Aβ occur when the amyloid-beta precursor protein (APP) is proteolytically processed by β- and then γ-secretase in the amyloidogenic pathway. READ MORE

4. Studies of cytotoxic T lymphocytes and natural killer cells in relation to MHC class I presented peptides
Abstract : In the defense against disease it is essential for the immune system to be able to discriminate self/normal from non-self/abnormal. This key feature of the immune system relies on the presentation of antigens by MHC class I and class II molecules. READ MORE

5. Immunity and immunosuppression in the tumor-host interaction
Abstract : With the advent of new methods in molecular biology and in peptide isolation, a number of tumor-associated antigens and their epitopes have been identified and characterized. However, tumors often grow progressively evolving different mechanisms of immune escape, resulting in resistance to MHC class I-restricted tumor-specific T cells. READ MORE
