Abstract

Traditional ideas about how the immune system responds to injury and infection of neural tissue are now being revised, particularly with respect to intervention by T-lymphocytes. They require major histocompatibility complex (MHC) antigens for cellular recognition. Recent investigations have revealed the vigorous expression of HLA-DR, a MHC class II antigen by reactive microglia in Alzheimer’s and Parkinson’s disease as well as some other neurological disorders1,2. The major known function of HLA-DR is to present foreign antigen to T-helper/inducer cells. In affected areas of Alzheimer’s disease brain, a significant number of T-lymphocytes have also been detected3, indicating that the appropriate tissue elements for a cell mediated immune response are present. The purpose of this study was to investigate the response of immune components to controlled sterile lesions to rat brain. Such information should contribute to understanding data obtained in human degenerative neurological diseases.
