Abstract

The inflammation on central nervous system (CNS) is an important factor in great number of neurological diseases, including autoimmune diseases to neurodegenerative diseases. The type of inflammation on CNS and the participation of cell types of immunological system can differ greatly depending on the disease. An essential role has been assigned to CD8 T lymphocytes in animal models of CNS inflammation and in several other neurological diseases like multiple sclerosis, Rasmussen encephalitis, viral encephalitis and paraneoplastic neurological degeneration. Furthermore, the involvement of CD8 T cells in autoimmune diseases that affect the CNS has received increased attention and complemented through the observation of resident cells on CNS, including neurons, that express the MHC (major histocompatibility complex) molecule class I in constitutive way. However, little is known from literature about the contribution of CD8 T cells in the inflammation and damage to CNS. The general objective of this project is to identify the traffic signaling involved on the recruitment of CD8 T cells to the CNS during the inflammatory disease. For this, we propose to investigate the in vitro migration of CD8 T cells in the CNS using organotypic cerebellar culture from double knock-in L7-HA mice that express the hemagglutinin protein (HA) of influenza virus only in Purkinje cells. Therefore, we purpose to identify the molecular pathways that allow the specific blocking of pathogenic CD8 T cells. (AU)
