2. Virulence determinants of the insect pathogen Bacillus thuringiensis; : Molecular characterization of flagellins and the virulence protease immune inhibitor A
Abstract : Bacillus thuringiensis (Bt) is a motile, Gram positive, rod-shaped and spore-forminginsect pathogenic bacterium found on plants and in soil. The main insecticidal activityresides in a proteinacious crystal inclusion body (the S-endotoxin), but also the sporesare important for lethality. READ MORE

3. Apoptosis and tumor cell death pathways in response to HAMLET
Abstract : HAMLET (Human alpha-lactalbumin made lethal to tumor cells) is a molecular complex of alpha-lactalbumin and oleic acid, that induces programmed cells death in tumor cells but leaves healthy differentiated cells unaffected. It has a broad anti-tumor activity as more than 40 cell lines from different origin are sensitive. READ MORE
