11. Protein tyrosine kinases and the regulation of signalling and adhesion in drosophila melanogaster
Abstract : In order to build a multi-cellular organism and to regulate cellular functions, cells need to communicate with each other, as well as tightly regulate their behaviour in response to environmental changes. For these purposes all eukaryotic cells express a large number of membrane spanning receptors that either themselves contain catalytic activity or via cytoplasmic effector enzymes, function to transmit “signals” from the cell exterior to induce appropriate responses within the cell.

12. Genetic studies of zebrafish muscles : clues to protection in muscle disease
Abstract : Muscular dystrophies (MDs) are caused by dysregulation of over 40 proteins but commonly share features of muscle weakness, myofiber death and regeneration, loss of ambulation and premature death. A MD involves a broken link anywhere in the connection from extracellular matrix through the sarcolemma to the sarcomere. READ MORE

13. T lymphocytes and cytokines in the pathogenesis of experimental autoimmune myasthenia gravis
Abstract : Experimental autoimmune myasthenia gravis (EAMG), induced in different animal species and strains by immunization with nicotinic acetylcholine receptor (AChR) and complete Freund's adjuvant (CFA), represents an experimental model of myasthenia gravis (MG) in humans. Both MG and EAMG are autoimmune diseases mediated by antibodies against AChR of neuromuscular junctions. READ MORE

14. Studies on co-stimulatory molecules, chemokines and chemokine receptors in neuroimmunological diseases
Abstract : Background: Multiple sclerosis (MS) and myasthenia gravis (MG) are characterised by activation of T cells directed against self antigens. Such autoreactive T cells are considered to play a central role in destruction of myelin in MS and in damage of neuromuscular junctions in MG. READ MORE

15. Spinal motoneurons and molecules related to neurotrophic function after axon injury
Abstract : The capacity of motoneurons to survive and regenerate new axons after injuries such as axotomy depends on a great variety of parameters. After sciatic nerve transection (SNT) in adult rats and to some extent after a ventral funiculus lesion (VFL), many cells survive and regeneration is highly prioritized. READ MORE
