Chapter 2 A SECRETED LIGAND FOR GROWTH CONE RECEPTORS, VAP MEDIATES THE CELLULAR PATHOLOGICAL DEFECTS IN ALS ABSTRACT; ABBREVIATIONS ; INTRODUCTION ; STUDIES ON MUTATIONS ASSOCIATED WITH FAMILIAL FORMS OF ALS ENABLE US TO UNDERSTAND THE CORE PATHOLOGY OF ALS ; DOMINANTLY INHERITED MISSENSE MUTATIONS IN VAP ARE ASSOCIATED WITH A FAMILIAL FORM OF ALS ; VAP IS AN ER TRANSMEMBRANE PROTEIN CONTAINING A MSP DOMAIN ; VAP FUNCTIONS IN NOVEL SIGNALLING PATHWAYS ; CLEAVAGE OF VAP RELEASES MSP DOMAIN-CONTAINING FRAGMENTS THAT ARE SECRETED.

VAP ACTS AS A LIGAND FOR EPH RECEPTOR AND MEDIATES EPH SIGNALLING VAP MSP MEDIATES ROBO AND LAR RECEPTORS AND FUNCTIONS IN THE MAINTENANCE OF THE MITOCHONDRIA IN MUSCLE ; ALS MUTATION CAUSES TWO DIFFERENT TYPES OF DEFECTS: A FAILURE OF VAP SECRETION (LOSS-OF-FUNCTION) AND ER STRESS (GAIN-OF-FUNCTION) AND ER STRESS (GAIN-OF-FUNCTION OR TOXIC DEFECTS) ; CONCLUSION ; ABOUT THE AUTHORS ; REFERENCES ; Chapter 3 FLIES IN MOTION: WHAT DROSOPHILA CAN TELL US ABOUT AMYOTROPHIC LATERAL SCLEROSIS ; ABSTRACT ; INTRODUCTION ; ALS IN MODEL ORGANISMS: YEAST TO MICE ; Current Hypotheses for ALS.
