    • Abstract: Systemic lupus erythematosus (SLE) is a disease characterized by the production of multiple autoantibodies, most notably antibodies to double stranded DNA. A subset of these anti-DNA antibodies cross-reacts with the NR2A and NR2B subunits of the NMDA receptor. This receptor is the primary molecular mechanism for controlling synaptic plasticity and memory function. These antibodies are present in serum of approximately 50% of patients. They can be found in cerebrospinal fluid of patients with neuropsychiatric lupus, and their titers correlate with symptomatology. They can also be found in brain tissue. In vivo in mice, they mediate memory loss if they access the hippocampus or impaired fear conditioning if they access the amygdala. These antibodies modulate excitatory post synaptic potentials at low concentration and induce mitochondrial transition permeability and apoptosis at high concentration. When these antibodies are present in serum of pregnant mice, they alter fetal brain development in a dose dependent fashion and can lead to permanent but isolated cognitive impairments. Dr. Diamond will present information from studies that show that: 1) anti-brain antibodies may be responsible for multiple instances of altered cognition and behavior in adults, and altered brain development in fetuses, and 2) such antibodies may arise in susceptible individuals in response to microbial challenge. She will also discuss studies of anti-pneumococcal antibodies that support this hypothesis.

    • Abstract: The human Bloom Syndrome DNA helicase BLM and its yeast ortholog Sgs1 are large proteins that are well-known for their role in maintaining genome stability. However, the function of the N-terminal halves of these proteins is largely unknown - even though genetic analysis in yeast indicates that they are critical for Sgs1 function in-vivo. We have now performed biochemical studies on this 650 aa portion of the protein. We have identified a region that binds DNA and will describe its biochemical activities. A second approach to understanding Sgs1 function involves the study of genes required in the absence of SGS1 (1). Such synthetic-lethal screens have identified genes involved in the regulation of sumoylated proteins, such as the Slx5-Slx8 SUMO-dependent Ub ligase (2), but not the more common SUMO regulators such as the SUMO E1, E2, E3s, or Ulps. I will describe the activity of a new synthetic interactor, Wss1, involved in regulating the stability of sumoylated proteins. The results suggest that recombination-dependent DNA repair is regulated by a unique form of sumoylation. 1. Mullen, J. R., Kaliraman, V., Ibrahim, S. S., and Brill, S. J. (2001).

    • Abstract: Electrical stimulation (ES) of the brain has been performed for over 100 years, and although some might say it is a crude technique for understanding the detailed mechanisms underlying different neural computations, microstimulation has made significant contributions to our knowledge in both basic and clinical research. Recently there has been resurgence in its use in the context of electrotherapy and neural prostheses. For example, ES has made it possible to at least partially restore hearing to deaf patients by delivering pulses via implanted electrodes to different regions of the cochlea. Stimulation of the basal ganglia is remarkably effective in restoring motor function to Parkinsons patients, and microstimulation of the geniculostriate visual pathway is regarded by some as a very promising (future) method for making the blind see again. Yet, the methodology still suffers from at least two fundamental problems; (a) we do not always know exactly what is being stimulated when we pass currents through the tissue; and (b) stimulation causes activation in a large number of areas even outside the stimulation site, making it difficult to isolate and evaluate the behavioral effects of the stimulated area itself. Microstimulation during fMRI (esfMRI) could provide a unique opportunity to visualize the networks underlying electrostimulation-induced behaviors, to map neuromodulatory systems, or to develop electrotherapy and neural prosthetic devices. Last but not least, esfMRI can offer important insights into the functional neurovascular coupling. In my talk, I shall discuss findings from recent and on-going work on signal propagation during electrical stimulation. These findings not only offer some insights into functional neurovascular coupling and the interpretation of negative hemodynamic responses, but also reveal some interesting properties of the cortical microcircuits and the way they could propagate incoming population signals.
