Cellular immunology, T cell immunity, autoimmune diseases: The immune system plays a fundamental role in the defense against microbial pathogens. However, erroneous activation of the immune system can lead to autoimmune diseases. This laboratory pursues several lines of investigation to understand how T cells contribute to autoimmune diseases and protection from infection, and how to modulate T cell immunity for therapeutic purposes in humans.
Brian Hermann, Ph.D.
Student projects in my lab will revolve around cell-fate decisions in Spermatogonial Stem Cells (SSC). SSCs are adult-tissue stem cells in the mammalian testis that balance self renewing and differentiating fate decisions to give rise to and sustain the entire spermatogenic lineage. The molecular mechanisms that control these fate decisions in SSCs are largely unknown transcriptional programs critical for SSC function. We are testing the hypothesis that specific transcription factors form regulatory networks to execute gene expression programs important for SSC fate decisions (self-renewal and differentiation), and ultimately, spermatogenesis. My laboratory also studies fertility preservation in male cancer patients.

Jose Lopez-Ribot, Pharm.D., Ph.D.
Research focuses on opportunistic pathogenic fungus Candida albicans. C. albicans is part of the normal human microbiota. However, as an opportunistic pathogen it is capable of causing overt disease (candidiasis), but usually only in hosts with defective immunity. The frequency of candidiasis has increased dramatically in the last decades as a result of an expanding population of immunocompromised patients. As a result, candidiasis is now the fourth most common nosocomial infections. Even with treatment using available antifungal agents, mortality rates lie in the 30- 40% range for these infected patients. As an opportunistic pathogen, it is clear that mechanisms of host immunity and pathogen virulence intertwine, giving rise to the highly complex nature of host-fungus interactions. However, most investigations into these topics are overwhelmingly "one-sided" which has resulted in a dangerous dichotomy between "microorganism-centered" and "host-centered" views of candidal pathogenesis.
Martha Lundell, Ph.D.
Current research is focused on elucidating a mechanism of differentiation for one particular neuronal cell type, the serotonergic neurons in the ventral nerve cord of Drosophila. The sophisticated molecular and genetic techniques available in Drosophila allow one to ask specific questions on cellular differentiation that cannot be asked in any other model system. A number of genes and cell signaling pathways have been characterized that are important to the development of the serotonergic lineage and are now examining how these molecules interact to specify serotonin cell fate. Another area of research in the laboratory is the relationship of genomic instability and aging. Investigation includes the genomic instability using a transgenic Drosophila lacZ-reporter system.

Carlos Paladini, Ph.D.
Research focuses on two broad approaches to study dopamine system physiology: 1) direct manipulation of receptor interactions on individual dopamine neurons in vivo and in vitro to investigate normal physiology and function; and 2) behaviorally-induced changes of receptor interactions via drug self-administration assays, which will determine the causal relationship between altered receptor interactions and drug-seeking behaviors. To achieve the first goal, we measure physiological responses (i.e., current, voltage and calcium fluxes) of dopamine neurons to electrophysiological stimulation and direct application of pharmacological agents. For the second goal, we use behavioral measures and electrophysiological techniques in tandem. Through combined electrophysiological, imaging, pharmacological, and behavioral methods we investigate dopamine neuron function to arrive at the functional contribution of this system in both normal and pathological states.
Robert Renthal, Ph.D.
Research focus includes: 1) Insect sensory reception: How is information stored and transferred by social insects? Ant colonies are considered to be prime examples of "self-organizing" systems.

Using biophysical and genetic methods, studies are involved in association and folding of model transmembrane peptides and integral membrane proteins.

Some of the highlights of this research program are: i) the role of morphogenetic conversions (shape changes) in the pathogenesis of candidiasis, ii) analysis of global gene expression changes during infection and iii) high throughput screening of small molecule libraries in an attempt to identify potential new therapeutic agents for candidiasis.
Valerie Sponsel, Ph.D.
Research looks at growth and development in the model plant Arabidopsis thaliana, which is easy to grow, has a short life cycle, has a small genome, and produces thousands of seeds per plant. By making genetic mutants of Arabidopsis we are able to select for mutant plants in which processes that are known to be controlled by gibberellins are altered. An investigation into which biochemical processes have been altered or perturbed in a mutant can lead to a clearer understanding of how those processes operate in wild-type individuals. In turn this information may be use to determine how plant growth or development could be manipulated in a specific manner to improve crop productivity and yield.

The focus of my research is to examine bone cell interactions with biomaterials and to study the pathways of cell differentiation into mature tissues. To clarify cell-biomaterial interactions we examine the integrin receptor activity of cells during their first contact with a biomaterial. Sub-cellular signaling pathways have been identified to track key players such as the stress activated protein kinases (SAPK), viability markers such as P38 and differentiation gene transcription factor RUNX2. By following pathways from outside the cell, through internal protein signaling and finally to the production of specific proteins by the cell, we can help explain the mechanisms responsible for implant rejection or successful long-term integration.
