1. Cathepsin D released from lysosomes mediates apoptosis
Abstract : Last year (2002), the Nobel Prize in Physiology or Medicine was awarded to three scientists who have conducted pioneer research on programmed cell death. In the human body, more than a thousand billion cells are created every day, and an equal number die, thus programmed cell death, or apoptosis, is an important mechanism for maintaining tissue homeostasis and protecting against disease.

2. The involvement of degradation pathways and neuron-to-neuron transmission in Alzheimer’s disease
Abstract : Although the vast majority of Alzheimer’s disease (AD) cases are of the sporadic type, mutations causing the familial form have been the focus of AD research for decades. The disease is pathologically characterised by β-amyloid (Aβ) and tau protein aggregates in neuritic plaques and neurofibrillary tangles. READ MORE

3. Lysosomal Membrane Stability and Cathepsins in Cell Death
Abstract : Lysosomes are acidic organelles that are critically involved in a number of physiological processes, including macromolecule degradation, endocytosis, autophagy, exocytosis and cholesterol homeostasis. Several pathological conditions, such as cancer, neurodegenerative disorders and lysosomal storage diseases, involve lysosomal disturbances, indicating the importance of the organelle for correct cellular function.

4. Amyloid-β and lysozyme proteotoxicity in Drosophila : Beneficial effects of lysozyme and serum amyloid P component in models of Alzheimer’s disease and lysozyme amyloidosis
Abstract : In the work presented this thesis, two different conditions that are classified as protein misfolding diseases: Alzheimer's disease and lysozyme amyloidosis and proteins that could have a beneficial effect in these diseases, have been studied using Drosophila melanogaster, commonly known as the fruit fly. The fruit fly has been used for over 100 years to study and better understand fundamental biological processes. READ MORE

5. Lysosomal network proteins as biomarkers and therapeutic targets in neurodegenerative disease
Abstract : The pre-symptomatic stage of neurodegenerative diseases such as Alzheimer’s disease (AD) and Parkinson’s disease (PD) occurs several decades before the clinical onset. Changes in the lysosomal network, i.e. the autophagosomal, endosomal and lysosomal vesicular system, are among the first alterations observed. READ MORE
