BIO-480: Neuroscience: from molecular mechanisms to disease

The goal of the course is to guide students through the essential aspects of molecular neuroscience and neurodegenerative diseases. The student will gain the ability to dissect the molecular basis of disease in the nervous system in order to begin to under ...

Description

This lecture covers the synthesis of epinephrine, the mechanism of action of Ritalin as a cognitive enhancer, and the effects of different drugs on neurotransmitters. The exercises include identifying drugs for Alzheimer's, understanding potency vs. efficacy, and discussing the use of anesthetics. The lecture also delves into the differences between toxins like botox and bengarotoxins, their effects on synapses, and the role of neurotransmitters in regulating heart function.

Lansbury 2000-2001 Research Scientist, The Picower Institute for Medical Research, Great Neck New York 1994-2000 PhD Student; Texas A&M University and the Scripps Research Institute Advisor- Prof. Jeffery W. Kelly 1990-1994 B.S. City University of New York, Brooklyn College Dr. Hilal A. Lashuel received his B.Sc. degree in chemistry from the City University of New York in 1994 and completed his doctoral studies at Texas A&M University and the Scripps Research Institute in 2000. After obtaining his doctoral degree, he became a research fellow at the Picower Institute for Medical Research in Long Island New York. In 2001, he moved to Harvard Medical School and the Brigham and Women's Hospital as a research fellow in the Center for Neurologic Diseases and was later promoted to an instructor in neurology at Harvard Medical School. During his tenure (2001-2004) at Harvard Medical School his work focused on understanding the mechanisms of protein misfolding and fibrillogenesis and the role of these processes in the pathogenesis of Parkinson's and Alzheimer's disease. In 2005 Dr. Lashuel moved Switzerland to join the Brain Mind Institute at the Swiss Federal Institute of Technology Lausanne as a tenure-track assistant professor in neurosciences. Currently, Dr. Lashuel is an associate professor of life sciences and the director of the laboratory of molecular and chemical biology of neurodegeneration. (http://lashuel-lab.epfl.ch/). Research efforts in the Lashuels laboratory focus on understanding the molecular mechanisms of neurodegeneration and developing novel strategies to diagnose and treat neurodegenerative diseases such as Alzheimers and Parkinsons disease. Research in the Lashuel lab is funded by several international funding agencies and foundations, including the Swiss National Science Foundation, European FP7 program (Marie Curie and ERC grants), Human Science Frontiers, Strauss Foundation, Cure the Huntingtons disease foundation and Michael J Fox foundation and is supported by collaborations with pharmaceutical and biotech companies (http://lashuel-lab.epfl.ch/page-50538-en.html), Nestle, Merck-Serono, AC Immune and Johnson and Johnson. Dr. Lashuels research has resulted in the characterization of novel quaternary structure intermediates on the amyloid pathway, identification of potential therapeutic targets, and new hypotheses concerning the mechanisms of pathogenesis in Alzheimers disease, Parkinsons disease and related disorders. Dr. Lashuel scientific contribution to this field includes i) more than100 publications in major peer reviewed journals including Nature journals, Cell, PNAS, JBC, J. Neuroscience JACS, and Angewandtie Chemie; ii) three patents on novel strategies for preventing protein aggregation and treating autoimmune and inflammatory diseases; iii) more than 150 invited lectures since 2002 and more than 5500 citations (7800 citation-Google Scholar) since 1996. Dr. Lashuel has received several pre-doctoral and post-doctoral awards and fellowships and was the recipient of two prestigious awards given to young investigators; Human Science Frontiers young investigator research award and the European Research Council (ERC) starting independent researcher grant and the ERC proof of concept award (2013) These awards provide more than $2.5 Million to Dr. Lashuel to translate some of his ideas and projects into novel strategies for diagnosing and treating neurodegenerative diseases such as Alzheimers and Parkinsons disease. Dr. Lashuel has chaired and co-organized several international conferences and serves as an academic editor for PLoS ONE, an associate editor for frontiers of molecular neuroscience, member of the Editorial advisory board of ChemBioChem and ad hoc reviewer for several international scientific journals and funding agencies.

Neurotransmitter

A neurotransmitter is a signaling molecule secreted by a neuron to affect another cell across a synapse. The cell receiving the signal, or target cell, may be another neuron, but could also be a gland or muscle cell. Neurotransmitters are released from synaptic vesicles into the synaptic cleft where they are able to interact with neurotransmitter receptors on the target cell. The neurotransmitter's effect on the target cell is determined by the receptor it binds to.

Monoamine neurotransmitter

Monoamine neurotransmitters are neurotransmitters and neuromodulators that contain one amino group connected to an aromatic ring by a two-carbon chain (such as -CH2-CH2-). Examples are dopamine, norepinephrine and serotonin. All monoamines are derived from aromatic amino acids like phenylalanine, tyrosine, and tryptophan by the action of aromatic amino acid decarboxylase enzymes. They are deactivated in the body by the enzymes known as monoamine oxidases which clip off the amine group. Monoaminergic systems, i.

Retrograde signaling

Retrograde signaling in biology is the process where a signal travels backwards from a target source to its original source. For example, the nucleus of a cell is the original source for creating signaling proteins. During retrograde signaling, instead of signals leaving the nucleus, they are sent to the nucleus. In cell biology, this type of signaling typically occurs between the mitochondria or chloroplast and the nucleus. Signaling molecules from the mitochondria or chloroplast act on the nucleus to affect nuclear gene expression.

Heart

The heart is a muscular organ in most animals. This organ pumps blood through the blood vessels of the circulatory system. The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs. In humans, the heart is approximately the size of a closed fist and is located between the lungs, in the middle compartment of the chest, called the mediastinum. In humans, other mammals, and birds, the heart is divided into four chambers: upper left and right atria and lower left and right ventricles.

Heart failure

Heart failure (HF), also known as congestive heart failure (CHF), is a syndrome, a group of signs and symptoms, caused by an impairment of the heart's blood pumping function. Symptoms typically include shortness of breath, excessive fatigue, and leg swelling. The shortness of breath may occur with exertion or while lying down, and may wake people up during the night. Chest pain, including angina, is not usually caused by heart failure, but may occur if the heart failure was caused by a heart attack.
