Cáceres Laboratory 

Dr. Alfredo Cáceres       

Was born in 1952 in Córdoba, Argentina. He graduated as a physician in 1975 from the School of Medicine (National University of Córdoba) and obtained a PhD in Medicine (1979) from the same University supervised by Dr. Samuel Taleisnik. At the Instituto Mercedes Martín Ferreyra (INIMEC-CONICET-UNC). He did postdoctoral work (1980-1982) with Dr. Oswald Steward (University of Virginia, Charlottesville, Virginia, USA) and Dr. Gary A. Banker (Albany Medical College, New York, USA) work that establish the existence of fundamental differences in the organization of the axonal and dendritic cytoskeleton and lead to the concept of neuronal polarity. Since 1982 he is a member of the National Research Council of Argentina (CONICET) and currently the Director of the Instituto Investigación Médica Mercedes Martín Ferreyra (INIMEC-CONICET-UNC). He has been a Visiting Scientist at the Center Neurological Diseases (Harvard Medical School, Boston, USA, 1989-1990), Visiting Professor at the Dyson Vision Institute (Cornell Medical College, NYC, USA, 2003-2004) and at the Max Plank Institute of Biophysical Chemistry (Göttingen, Germany, 2014). From 1997 to 2006 he was an International Research Scholar of the Howard Hughes Medical Institute (HHMI) and in 2018 was elected Associate Member of the European Molecular Biology Organization (EMBO). He has received several awards and prizes including the Fogarty International Fellowship (1980), the Guggenheim Fellowship (2002), the Alexander von Humboldt Research Award (2013) and the Konex Award (2013). He has published more than 90 articles in international peer-reviewed journal, supervised 15 PhD theses, many undergraduate students and postdoctoral fellows. He is a member of the Society of Neuroscience (SfN, USA), the American Society of Cell Biology (ASCB, USA) and the Argentine Society of Neuroscience, where he served as Vice-President.

The research of Dr. Cáceres group seeks to obtain insignhts about the participation of cytoskeletal proteins in the development of neuronal polarity. A combination of cellular and molecular biology procedures, including advanced imaging techniques in living cells, is currently being used in his laboratory. Neurons are highly polarized cells capable of generating a long axon and several highly branched dendrites. Axons and dendrites differ in their cytoskeleton components, distribution of organelles, membrane proteins, and their function. The knowledge of the cellular and molecular mechanisms involved in the development and maintenance of neuronal polarity is fundamental to understand how the nervous circuits are generated and how they function. This information is also of great importance to understand the pathogenesis of neurodegenerative diseases such as Alzheimer's and Parkinson's. During the last 30 years, our research group has been dedicated to study the role of the cytoskeleton and signaling pathways (e.g., small RhoGTPases: RhoA, Rac, Cdc42, etc.) in the establishment of neuronal polarity. At present, we study the organization and dynamics of microtubules, actin filaments, and RhoA during axonal formation using multidimensional microscopy and nanoscopy (STED, STORM). We also study the biogenesis of membrane organelles, such as dendritic mini-Golgi apparatuses (GOPs) and the regulation of the differential traffic of membrane proteins to axons and dendrites. Finally, we studied the morpho-dynamics events of neuronal polarization in embryonic stem cells of murine origin and in iPSCs ("Induced Pluripotent Stem Cells") obtained from normal individuals and with genetic variants associated with Alzheimer's disease.

Associate Researchers

   Dr. Mónica Sanchez

Dr. Mónica Silvina Sanchez graduated as Biochemistry from the National University of Córdoba, Argentina in 1995 and in 2000 obtained her Doctorate in Chemical Sciences from the same University. She completed her post-doctoral studies at the Center of Excellence in Products and Processes of the Province of Córdoba (CEPROCOR), under the guidance of Drs. Alfredo Cáceres and Carlos Landa. She is currently an Adjunct Researcher of the National Council for Scientific and Technical Research (CONICET) and carries out her research work in the Neurobiology Laboratory of the Mercedes and Martin Ferreyra Institute in Córdoba, Argentina. She is currently studying the effect of rotenone, a naturally-occurring compound widely used as an insecticide, on the development of the polarity of hippocampal neurons in rat embryos. Taking into account the few existing data on the effect of rotenone on the central nervous system, her work studies whether the insecticide has a marked neurotoxic effect on developing hippocampal neurons and, more importantly, the cellular mechanisms by which the pesticide affects the development of neuronal polarity. Therefore, their findings highlight the importance of establishing rigorous control over the use of the pesticide to protect the health of mammals.

His studies were carried out in collaboration with Dr. Francis S. Lee and Dr. Moses V. Chao. His research focused on clarifying the activation mechanisms of the neurotrophin receptor p75NTR and the study of a single nucleotide polymorphism (SNP) in the BDNF gene that is highly associated with an increased risk to develop psychiatric and neurodegenerative diseases. In 2015 Dr. Anastasia returned to Argentina as CONICET (National Research Council) Researcher and established his laboratory at the Instituto Ferreyra (INIMEC-CONICET-Universidad Nacional de Córdoba). Dr. Anastasia is a Professor of Neurophysiology and Psychophysiology at the School of Psychology (Universidad Nacional de Córdoba), and Professor of Cell Biology at the Instituto Universitario de Ciencias Biomédicas de Córdoba (IUCBC).

Bisbal Laboratory 

    Dr. Mariano Bisbal

Dr. Bisbal obtained his Biologist degree at the Faculty of Exact, Physical and Natural Sciences of the National University of Córdoba (FCEFyN-UNC), Argentina and completed his studies obtaining his Ph.D in Biological Sciences at the same University. He moved to Grenoble, France where he performed two post-doctoral stays at the Grenoble Institute of Neurosciences (Grenoble Institute of Neuroscience - INSERM (2009-2013)). During this period, he studied the development of neuronal polarity using substrate micropattern techniques and, later, he investigated the role of the microtubule associated protein MAP6 during the formation and maintenance of dendritic spines. In 2013, he came back to Argentine, where he joined the Neurobiology laboratory at the Instituto de Investigación "Mercedes y Martín Ferreyra” in Córdoba to start his own research line and establish his laboratory. He is currently a Research Associate from CONICET. The project led by Dr. Bisbal studies the cellular and molecular mechanisms involved in the regulation of the formation and maintenance of neuronal polarity, a critical phenomenon to understand both the development and normal functioning of the nervous system, as well as the pathogenesis of neurodegenerative diseases.
