Brainflammation: The Role of the Innate Immune System in CNS Disorders
Tuesday, December 6, 2011
Presented By
Neuroinflammation has been implicated in nearly every disorder of the CNS. As the resident innate immune cells of the CNS, microglia are the vanguard in host defense and in tissue repair. Their constant surveillance of the CNS enables them to rapidly respond to invading pathogens as well as mechanical or chemical injury. However, a growing body of evidence indicates that chronic or maladaptive activation of these very same cells plays a critical role in a variety of CNS disorders (including autism, psychiatric disorders, epilepsy, and neurodegenerative diseases such as AD, PD, ALS, and MS). Furthermore, recent work suggests that peripheral monocytes (another component of the innate immune system) may also become activated and then recruited to the CNS where they contribute to the regulation of neuroinflammation and the course of such disorders. These two cell populations, separated by the blood brain barrier and time, may therefore provide a key link between peripheral and central inflammatory processes. This symposium gathers experts on microglia/monocyte biology to discuss the role of the innate immune system in neurological disorders, what insights can be learned about their biology from their dysfunction in various disease contexts, and possible therapeutic interventions.
Networking reception to follow.

Sean Pintchovski, PhD
Lundbeck Research USA
Dr. Pintchovski earned a BS with Honors from the California Institute of Technology and a PhD in Neuroscience from the University of California, San Francisco while working at the Gladstone Institute of Neurological Disease and studying the regulation of neuronal gene expression underlying memory and cognition. After completing a postdoctoral fellowship at Elan Pharmaceuticals, where he worked to further elucidate key processes that contribute to cognitive decline in Alzheimer's disease, Dr. Pintchovski joined the Neuroinflammation Department at Lundbeck as a research scientist in early 2010. At Lundbeck his efforts have focused on applying a range of cutting edge techniques, including ex vivo FACS, to uncover how dysregulation of the immune system contributes to the pathogenesis of various neurodegenerative and psychiatric conditions. Dr. Pintchovski is driven by the desire to translate such fundamental discoveries into novel therapeutic approaches that will address the medical and social challenges posed by these devastating diseases.
Roland Staal, PhD
Lundbeck Research USA
Roland Staal received his PhD in Pharmacology from the University of Medicine and Dentistry of NJ with a focus on in vivo models of dopaminergic neurodegeneration, including amphetamines and MPTP, an animal model of Parkinson's disease. He did his post-doctoral studies at Columbia University, where he studied the function of alpha-synuclein as well as its role in sensitizing mice to the Parkinsonian neurotoxin MPTP. He then joined Wyeth Research's department of neurodegeneration, studying protein mis-folding and potential therapeutic interventions including aggregation inhibitors and immunotherapies for both Parkinson's and Alzheimer's disease. He then joined Lundbeck Research, where he was instrumental in establishing the Neuroinflammation biology unit. The unit works with various technologies including flow cytometry, cell sorting, ELISAs and Cellomics to evaluate various markers and outcomes of Neuroinflammation in in vivo models as well as cell lines and primary neuronal and microglial cultures. His current focus is on targeting neuroinflammatory aspects of CNS diseases, in particular, neuronal–microglial communication.

Speakers
Hemmo A. Drexhage, MD, PhD
Erasmus Medical Center
Dr. Hemmo A. Drexhage is professor in Medical Immunology at the ErasmusMC (Rotterdam). He graduated from medical school in 1974 (Amsterdam), defended his immunology PhD thesis in 1977 (Amsterdam) and studied immunology/medical immunology with Brigid Balfour/John Humphrey (Mill Hill) and Ivan Roitt and Deborah Doniach (Middlesex Hospital) in London from 1976–1981 (on exchange grants of the Royal Dutch and English Societies of Science). His subject of studies has ever since been focussed on the clinical picture and immune diagnosis of autoimmune diseases of endocrine glands (thyroid, islets of Langerhans, adrenal, ovary, pituitary) and the initiating role of aberrant dendritic cells and macrophages in thepathogenesis of these diseases. The higher prevalence of endocrine autoimmunities in severe mood disorders sparkled in 1996 his interest into studies on the role of immune cells in bipolar disorder, major depressive disorder, post partum psychosis and schizophrenia. He has published over 350 articles/book chapters on these subjects and supervised more than 30 PhD students.
Ru-Rong Ji, PhD
Harvard University and Brigham & Women's Hospital
Ru-Rong Ji received his PhD degree in Neurobiology at Shanghai Institute of Physiology, Chinese Academy of Sciences. He had postdoctoral trainings in Peking University, Karolinska Institute, and Harvard Medical School. Currently he is an associate professor at Brigham and Women's Hospital, Harvard Medical School. He is also director of Sensory Plasticity Laboratory and associate director of the Pain Research Center. He has been working on spinal cord mechanisms of chronic pain for 20 years. His work has demonstrated important roles of glial cells (eg., microglia), MAP kinase signaling pathways, and cytokines/chemokines in the control of neuropathic pain. His recent work has also revealed important role of pro-resolution lipid mediators in the resolution of inflammation and pain. Dr. Ji has published more than one hundred papers on chronic pain mechanisms and treatments.
Dave Morgan, PhD
University of South Florida
Dave Morgan is Chief Executive Officer/Director of the USF Health Byrd Alzheimer Institute, Distinguished Professor of Molecular Pharmacology and Physiology, and Director of Neuroscience Research for the College of Medicine and at the University of South Florida. Dr. Morgan’s research interests are aging and brain function, focusing on drugs to treat Alzheimer’s dementia. Morgan participated in the development of a transgenic mouse model of Alzheimer's disease (APP+PS1). His work focuses largely on the neuro-immune interactions associated with the Alzheimer phenotype, and the role of astrocytes and microglia in the disease process. He is presently testing anti-amyloid immunotherapy and gene therapy to treat the Alzheimer-like changes in transgenic mouse models of the disease. This work is supported by multiple grants from the NIH, private foundations and contracts from industrial partners. Morgan regularly sits on review panels for NIH and other agencies evaluating grants to develop new drugs to treat Alzheimer's and other neurodegenerative disorders.

Dr. Pardo's research interest and laboratory work focuses on studies of the 1) Immunopathological and molecular mechanisms of associated with neuroimmune disorders such as multiple sclerosis, neuroAIDS as well as epilepsy and autism, 2) the role of cytokines and chemokines in neurobiological processes and pathogenic mechanisms in neurological disorders, 3) Studies of biomarkers of neuroimunological disease in cerebrospinal fluid and blood and 4) Animal models of neuroimmunological disorders. Dr. Pardo's interest on autism centers on the role of neuroimmune factors and neuroglia in the pathogenesis of this neurodevelopmental disorder.

CD45 and CD40 Modulation of Microglial Activation: Implications for Alzheimer's and HIV Associated Dementias
Jun Tan, MD, PhD, University of South Florida College of Medicine
As an extension of this work in a related neurodegenerative disease, HIV associated cognitive disorders (HAND), we investigated the possible role of CD45 in microglial responsiveness to HIV-1 Tat protein. We BV2 microglia when treated with phen and HIV-1 Tat protein (100 nm) become activated in a synergistic pro-inflammatory manner as supported by TNF-&alpha and IL-1β release, both of which were dependent on p44/42 MAPK pathway activation. Stimulation of microglial CD45 by anti-CD45 antibody markedly inhibits these Tat or Tat/phen effects via inhibition of p44/42 MAPK, suggesting CD45 negatively regulates Tat mediated microglial activation. As a validation of these findings in vivo, brains from a transgenic mice deficient for CD45 demonstrate markedly increased production of TNF-α 24 hours after intracerebroventricular injection of Tat (500 ng/mouse) compared to control mice. This increased microglial activation was accompanied by astrogliosis and a significant loss of cortical neurons due to apoptosis in CD45 deficient animals. These results suggest therapeutic agents that activated CD45 PTP signaling may be effective in suppressing microglial activation associated with not only AD, but HAND as well.
