Lynn Kirby

Dr. Lynn Kirby

Dr. Kirby’s research focuses on the effects of stress and stress hormones on the serotonin (5-HT) system. Serotonin is a brain neurotransmitter that is involved in a wide range of behaviors, including emotional behaviors. Long-term exposure to stress is known to play a role in psychiatric disorders such as anxiety and depression. Stress is also a potent initiator of relapse in abstinent subjects with a prior history of substance abuse. Some of these clinical effects of stress may in part be mediated by 5-HT. In the laboratory, we have examined the effects of stress and stress hormones on the electrical activity of 5-HT-containing cells in the brain and the release of 5-HT from nerve terminals.

We have found that stress has qualitatively different effects on 5-HT neurotransmission depending on the brain region examined and the particular stressor that is employed. We have also examined the role of 5-HT in anxiety using a knockout mouse model in which a particular 5-HT receptor subtype (5-HT 1A) has been removed from the brain, resulting in an anxious behavioral phenotype. Previous studies also included investigation of the effects of chemokine immune molecules in the brain and their interactions with traditional neurotransmitter (5-HT, dopamine) and neuropeptide (opiate) systems. Currently, we are examining the potential role that 5-HT circuits play in opiate and cocaine addiction and relapse. Through collaborations with other laboratories we are also exploring cannabinoid effects on cognition, synaptic plasticity and inflammation produced in a model of stroke.

T. Dianne Langford

Dr. T. Dianne Langford

Studies in Dr. Langford’s lab focus on how cells of the brain respond to HIV infection of the central nervous system (CNS) and to other CNS-specific challenges including substance abuse and abnormal protein processing. We are interested in CNS cell response to the harmful effects of HIV infection, drugs of abuse, and other disorders associated with CNS dysfunction.  Specifically, we are focusing on mechanisms by which host cells attempt to preserve or restore normal cell functioning.  In earlier studies, we reported CNS cell-type specific protective responses to HIV-associated CNS challenge. More recent studies from our lab report the production of a protein called PINCH by neurons in the brains of HIV infected patients.

These results are particularly interesting since PINCH is undetectable in normal (un-diseased) brains.  In health, PINCH is expressed during development to maintain cellular polarity and communication with the extracellular matrix.  From our data, it appears that PINCH expression is recalled to repair or rescue damaged neurons.  To address potential triggers for PINCH induction in HIV patients’ brains we are using an in vitro system that mimics some aspects of HIV infection of the CNS (4).  Our data show that HIV proteins and inflammatory factors produced in response to HIV infection of CNS prompt PINCH expression.  Interestingly, sequestering PINCH using antibody-mediated mobility-disruption resulted in fewer and shorter neurite processes following treatment with the inflammatory factor, TNF-α, indicating that not only is PINCH increased upon challenge, but that it must also be free to migrate throughout the cell to maintain neurite extensions.

Nadine Martin

Dr. Nadine Martin

Dr. Martin’s research focuses on the relationship between word processing and short-term memory and the implications for rehabilitation of word retrieval disorders. Within these domains, she conducts both theoretical and treatment-oriented investigations. A primary theoretical interest concerns the architecture of lexical retrieval processes and their relation to verbal STM processes. Through the study of speech errors of normal and aphasic populations, she has sought empirical evidence and corroborating data from computational modeling studies to support a model of lexical retrieval that assumes interaction of semantic and phonological processes over the time course of lexical retrieval.

Additionally, her studies investigating the relationship between word processing and short-term memory deficits in individuals with neurologically-based language impairment indicate a common mechanism underlying these deficits: the ability to maintain activation of semantic and phonological aspects of words. Depending on the severity of this activation maintenance deficit, it will result in a verbal short-term memory and aphasia (more severe cases) or verbal short-term memory without aphasia. This work, carried out in collaboration with the late Eleanor Saffran and Gary Dell (University of Illinois), has led to several new lines of research including the development of a computationally-instantiated cognitive model of word processing and short-term memory and studies of the effects of language impairment on learning.

John Muschamp

Dr. John Muschamp

Dr. Muschamp’s laboratory studies the neurobiology of motivation, affect, and executive function and how they are altered in psychiatric disorders like drug addiction. To model these psychological constructs in animals we use a number of behavioral paradigms like intracranial self-stimulation (ICSS), place conditioning (CPP), and the 5-choice serial reaction time task (5CSRTT). To understand part of the neurocircuitry that is common to these different behaviors (i.e. the mesolimbic dopamine pathway), we have used in vivo microdialysis, electrophysiology, viral-mediated gene transfer, and a variety of neuroanatomical techniques. Important modulators of mesolimbic dopamine transmission are hypocretin (orexin) and dynorphin peptides released by projections from the hypothalamus. We have demonstrated that the hypocretin system is an essential integrator of reward-relevant information that potently excites the midbrain dopamine reward pathway.

We have also shown that attenuated hypocretin signaling decreases the reinforcing effects of cocaine, rewarding lateral hypothalamic electrical stimulation, and natural rewards like sex behavior. Additionally, we have also established that decreased hypocretin transmission attenuates spontaneous- and cocaine-induced impulsive behavior. These effects appear to arise from the ability of hypocretin to modulate the aversive or depressive-like effects of hypocretin’s cotransmitter dynorphin. Understanding the relationship and interactions between hypocretin and dynorphin is a major goal of our research. Because disturbances in mood, motivation, and executive function often accompany addiction and other psychiatric illnesses (e.g. bipolar disorder), and may be mediated by disrupted function of the hypocretin-dynorphin system, our work is designed to determine the utility of hypocretin receptor antagonists for the treatment of substance use disorders or other psychiatric illnesses characterized by high levels of impulsivity.

Bassel Sawaya

Dr. Bassel E. Sawaya

Even in the HAART era where the viral load is below detection levels, the prevalence of HIV-1 associated neurocognitive disorders (HAND) remains high due to many reasons such as latent virus reactivation and drugs’ inability to efficiently cross the blood brain barrier (BBB). Therefore, it is important to understand the mechanisms leading to neuronal deregulation in HIV-1-infected patients in the HAART era. The lack of productive infection of neurons by HIV-1 suggests that viral and cellular proteins with neurotoxic activities that are released from HIV-1 infected target cells, or reservoirs cells for latent active virus, cause this neuronal deregulation.

The viral proteins Tat, Vpr and gp120 have been shown to alter the expression of various important cytokines and inflammatory proteins in infected and uninfected cells. The mechanisms and the cellular factors used by these proteins to cause neuronal damage remain unclear. Therefore, research in the Molecular Studies of Neurodegenerative Diseases (MSND) lab mainly focuses on the identification of these mechanisms utilizing molecular, virological, and cellular approaches to determine the cellular factors used by the viral proteins as well as their interplay with microRNAs to cause neuronal dysfunction.

Ellen Unterwald

Dr. Ellen Unterwald

Our research investigates cellular and molecular mechanisms involved in drug addiction. We are particularly interested in neuroadaptations in specific receptors, signal transduction pathways, and transcription factors that result from exposure to psychostimulants (eg, cocaine and amphetamine) and opiates (eg, morphine and heroin). These adaptations are important as they mediate the processes of drug tolerance, dependence, sensitization, withdrawal and craving, which form the basis of addictive disease. The roles of these molecules and pathways in addiction-related behaviors are investigated using several relevant animal models. Some of these studies focus on identification of novel targets for the prevention of relapse and treatment of addiction. Other studies investigate the relationship between stress, anxiety, and relapse to drug use.  It is anticipated that by identifying neurobiological alterations that occur during exposure to drugs of abuse, the molecular mechanisms of drug addiction will be elucidated and effective therapeutic strategies will follow. These research projects have been supported in part by grants from the National Institute on Drug Abuse (NIDA), the Department of Health, and Temple University.
