Emiliana Borrelli, PhD
Professor, Microbiology & Molecular Genetics

Research in the Borrelli’s laboratory focuses on the dopaminergic system and in particular on the dopamine D2 receptor (D2R) one of the major receptor of the system. The D2 receptor by two isoforms generated by alternatively splice of the ... same gene. We study the implication of these receptors in neurological and neuropsychiatric disorders using mouse models carrying either the constitutive knockout of D2R or D2R cell-specific knockouts. These animals allowed the study of D2R as a whole or of each specific isoform and in specific neuronal types. These mice have been critical to analyze the specific function of D2R in vivo in substance use disorders. Studies in my laboratory are also analyzing complex neuronal circuits that control striatal responses affecting motor behavior and reward to food and addictive substances. In addition, we are elucidating mechanisms that underlie dyskinesia in response to the long-term L-DOPA therapy of Parkinson’s disease or as well as dopamine-related psychiatric disorders such as schizophrenia and other psychotic disorders.

Marcelo Wood, PhD
Professor & Chair, Neurobiology & Behavior

The research in my lab is focused on understanding the molecular mechanisms underlying learning and memory processes as well as drug-seeking behavior. I am particularly interested in examining the role of chromatin modifying enzymes in ... regulating transcription required for long-lasting types of memory and drug-seeking behavior. My lab uses a combined molecular, genetic, pharmacological and behavioral approach to examine the role of histone acetyltransferase (HAT) and histone deacetylase (HDAC) enzymes. Histone acetylation is one major epigenetic mechanism of gene regulation. We are also examining the role of a neuron-specific nucleosome remodeling complex (nBAF) in regulating gene expression required for memory processes that has been implicated in human intellectual disability disorders. Nucleosome remodeling represents another major epigenetic mechanism. The overall hypothesis driving our research is that epigenetic mechanisms modulate neuronal function in dynamic yet potentially very stable ways that underlie long-term changes in behavior related to memory processes and drug-seeking behavior. In addition, my lab also examines the role of these epigenetic gene regulation mechanisms in the context of the aging brain, ameliorating age-dependent cognitive decline, as well as in mouse models of neurodegenerative disease.

Hu Zhao, DDS, PhD
Assistant Professor, College of Dentistry, Texas AM

Tissue clearing technique is becoming popular in recent years on studying brain and other neural tissue. By turning tissue transparent, intact organs can be directly visualized with a confocal microscope and 3-D images can be acquired without ... sectioning. Our lab has developed a new tissue clearing technique named PEG Associated Solvent System (PEGASOS). The PEGASOS method efficiently clears both hard and soft tissue to high transparency and protects endogenous fluorescence with no loss. PEGASOS is also the only current clearing method capable of clearing bones and teeth into fully transparency. Skull bone, teeth and femur can be turned into nearly invisible without losing GFP fluorescence. We were able to perform 3-D imaging for intact skull, mandible, femur or teeth with a confocal, 2-photon or light sheet microscope. Vasculature, nerves or fluorescence labelled cells deep inside of the organs could be directly visualized without sectioning. We aim to utilize tissue clearing based deep imaging to explore neural organization within brain, spinal cord and other body parts.
