    Principal Investigator:
    Marilyn Albert, Ph.D.
    Neurology

    The goal of the Johns Hopkins Alzheimer's Disease Research Center (ADRC) is to accelerate the d...iscovery of new treatments that are directed at the basic mechanisms of disease, and to hasten the time when effective treatments for AD and related disorders become a reality. We have a strong commitment to basic research regarding the underlying mechanisms of Alzheimer's Disease and related disorders, and how this may translate into effective treatment. We perform clinical research seeking to identify medications to delay or treat the symptoms of dementia. We also provided many educational programs for family members and professionals. view more

  • Esther Oh Lab

    Principal Investigator:
    Esther Oh, M.D., Ph.D.
    Medicine

    The Esther Oh Lab is interested in developing biological markers for pre-clinical stages of Alz...heimer's disease (AD). Our current research involves using transgenic models of AD to develop peripheral injections of monoclonal antibodies against amyloid-beta as a tool to detect a level of amyloid-beta that would be correlative to the amyloid-beta level in the brain. view more

  • Jun Hua Lab

    Lab Website

    Dr. Hua's research has centered on the development of novel MRI technologies for in vivo functi...onal and physiological imaging in the brain, and the application of such methods for studies in healthy and diseased brains. These include the development of human and animal MRI methods to measure functional brain activities, cerebral perfusion and oxygen metabolism at high (3 Tesla) and ultra-high (7 Tesla and above) magnetic fields. He is particularly interested in novel MRI approaches to image small blood and lymphatic vessels in the brain. Collaborating with clinical investigators, these techniques have been applied 1) to detect functional, vascular and metabolic abnormalities in the brain in neurodegenerative diseases such as Huntingdon's disease (HD), Parkinson's disease (PD), Alzheimer's disease (AD) and mental disorders such as schizophrenia; and 2) to map brain functions and cerebrovascular reactivity for presurgical planning in patients with vascular malformations, brain tumors and epilepsy. view more

  • Lee Martin Laboratory

    Lab Website
    Principal Investigator:
    Lee Martin, Ph.D.
    Pathology

    In the Lee Martin Laboratory, we are testing the hypothesis that selective vulnerability--the p...henomenon in which only certain groups of neurons degenerate in adult onset neurological disorders like amyotrophic lateral sclerosis and Alzheimer's disease--is dictated by brain regional connectivity, mitochondrial function and oxidative stress. We believe it is mediated by excitotoxic cell death resulting from abnormalities in excitatory glutamatergic signal transduction pathways, including glutamate transporters and glutamate receptors as well as their downstream intracellular signaling molecules.

    We are also investigating the contribution of neuronal/glial apoptosis and necrosis as cell death pathways in animal (including transgenic mice) models of acute and progressive neurodegeneration. We use a variety of anatomical and molecular neurobiological approaches, including neuronal tract-tracing techniques, immunocytochemistry, immunoblotting, antipeptide antibody production, transmission electron microscopy and DNA analysis to determine the precise regional and cellular vulnerabilities and the synaptic and molecular mechanisms that result in selective neuronal degeneration.

  • Psychiatric Neuroimaging

    Psychiatric Neuroimaging (PNI) is active in neuropsychiatric research using imaging methods suc...h as MRI, fMRI, PET and DTI to understand the mechanisms and brain networks underlying human cognition. PNI faculty have published hundreds of papers on a variety of brain disorders which include but are not limited to Alzheimer's disease, Parkinson's disease, bipolar disorder, and eating disorders. Faculty in the division have been awarded numerous peer-reviewed grants by the National Institutes of Health, foundations and other funding organizations.
