Apoptosis is a type of programmed cell death that is essential for the development and maintenance of tissue homeostasis in multicellular organisms. Because apoptosis is important in many biological s...
Role of lipid signalling pathways in an intra and an extracellular phenomenon
Lipid signal cells nuclear envelope lipid signal cells hela cell the membrane vesicles
2014/12/11
This dissertation is in two parts. The first part investigates the role of lipid signalling pathways in an intracellular phenomenon i.e. the formation of the nuclear envelope. The second part is a stu...
The role of cell cycle progression and cyclin -dependent kinase 2 in thymocyte negative selection
T cells and thymus cells thymus self antigen cells
2014/12/11
Autoreactive, immature T cells (thymocytes) are deleted from the thymus during development by the process of negative selection. This mechanism occurs when the thymocyte, T cell receptor (TCR) recogni...
The role of oxidative stress in apoptosis
Thymus cells thymus thymocyte apoptosis oxidative stress molecular oxygen oxidation of thiol
2014/12/11
Thymocytes undergo negative and positive selection during their development in the thymus. During this selection process, the majority of thymocytes are eliminated by apoptosis. In the first part of t...
