Cell adhesion molecules and intracellular proteins that facilitate the interactions between neuronal and glial cells of the nervous system: Design of therapeutic approaches for spinal cord injury

Abstract

Schwann cells (SC) are the glial cells of the peripheral nervous system (PNS) that contribute to the development, survival and function of neuronal cells as well as to peripheral nerve regeneration after injury. Furthermore, there is experimental evidence that SC could have beneficial applications in clinical transplantation for the repair of CNS after trauma. Yet SC do not integrate well into the injured tissue of the CNS. This study focuses on specific molecules for the development of combinatorial approaches for genetic manipulation of SC in order to overcome this disadvantage and become suitable for therapeutic transplantation in the injured CNS. In the first part, retroviruses were used as molecular vehicles for the expression of cell adhesion molecules Ll or PSA-NCAM by SC. In vivo experiments of transplantation of these genetically modified SC followed in a model of mouse spinal cord injury. The injured animals were subjected in behavioral study of their hind limb locomotor func ...
