RESEARCH INTEREST
Cardiovascular Biology, Cell Signaling, Physiology, Toxicology, Translational Medicine

Research in my laboratory focuses on the cardiovascular effects of air pollution and other environmental pollutants in human, animal, and in vitro models, as well as the dietary interventional strategies to mitigate the adverse health effects of air pollution exposure. We are currently conducting two clinical studies to investigate the cardiopulmonary effects of air pollution exposure, and to determine whether dietary omega-3 fatty acids can mitigate the air pollution-induced health effects in human volunteers. These studies provide good training opportunities for students who are interested in training in clinical and translational toxicology research.

The focus of the work in the Martinez lab is to examine the non-canonical roles for the autophagy machinery during inflammation. Our recent work about LC3-associated phagocytosis (LAP) higlights the importance of this non-canonical autophagic process in maintaining tolerance and preventing unwanted autoinflammatory pathologies.

Cytoskeletal-associated proteins are critical for the maintenance of cellular homeostasis, and their involvement in cancer and in numerous neurodegenerative, neurodevelopmental, psychiatric, heart, muscular, and metabolic disorders underscores their functional relevance.

Our lab investigates the contribution of the cytoskeleton to key physiological processes and the mechanistic basis of cytoskeleton-associated disorders. Our goal is to understand the roles of cytoskeletal proteins in the regulation of cellular dynamics and bioenergetics in metabolically active tissues as well as their involvement in brain development and connectivity. Our initial efforts focus on the ankyrin and spectrin families of cytoskeletal-associated proteins, which deficits have direct implications in the regulation of cell migration, in metabolic disorders such as obesity and diabetes, and may also underlie neurological diseases, including spinocerebellar ataxias, autism and West syndrome.

We combine human genetics, cellular and biochemistry approaches with Omics technologies and high resolution imaging-based assays in primary cells and in animal models of development and human disease.

During cell shape change and motility, a dynamic cytoskeleton produces the force to initiate plasma membrane protrusion, while vesicle trafficking supplies phospholipids and membrane proteins to the expanding plasma membrane. Extracellular cues activate intracellular signaling pathways to elicit specific cell shape changes and motility responses through coordinated cytoskeletal dynamics and vesicle trafficking. In my lab we are investigating the role of two ubiquitin ligases, TRIM9 and TRIM67, in the cell shape changes that occur during neuronal development. We utilize a variety techniques including high resolution live cell microscopy, gene disruption, mouse models, and biochemistry to understand the complex coordination of cytoskeletal dynamics and membrane trafficking driving neuronal shape change and growth cone motility in primary neurons.

Our primary research is in the area of computational systems biology, with particular interest in the study of biological signaling networks; trying to understand their structure, evolution and dynamics. In collaboration with wet lab experimentalists, we develop and apply computational models, including probabilistic graphical and multivariate methods along with more traditional engineering approaches such as system identification and control theory, to current challenges in molecular biology and medicine. Examples of recent research projects include: prediction of protein interaction networks, multivariate modeling of signal transduction networks, and development of methods for integrating large-scale genomic data sets.

My lab studies a recently identified pathogen-sensing signaling complex known as the inflammasome. The inflammasome is responsible for the proteolytic maturation of some cytokines and induces a novel necrotic cell death program. We have found that critical virulence factors from certain pathogens are able to activate NLRP3-mediated signaling, suggesting these pathogens may exploit this host signaling system in order to promote infections.  Our lab has active research projects in several areas relating to inflammasome signaling ranging from understanding basic molecular mechanisms of the pathway to studying the role of the system in animal models of infectious diseases.

We use an integrated approach (genomics, proteomics, computational biology) to study the molecular mechanisms of hormone and drug desensitization. Our current focus is on RGS proteins (regulators of G protein signaling) and post-translational modifications including ubiquitination and phosphorylation.

We study host defense mechanisms in the lungs, particularly the inflammatory and innate immune processes important in the pathogenesis and course of bacterial pneumonia, acute lung injury/acute respiratory distress syndrome, and cigarette smoke-associated lung disease. Basic and translational studies address mechanisms of host defense, including recruitment and function of leukocytes, vascular permeability leading to edema, bacterial clearance and resolution.  Cell signaling pathways initiated by binding of leukocyte-endothelial cell adhesion molecules and molecular mechanisms underlying the functions of neutrophils are two particular areas.

We study how mammalian cells regulate their survival and death (apoptosis). We have focused our work on identifying unique mechanisms by which these pathways are regulated in neurons, stem cells, and cancer cells. We utilize various techniques to examine this in primary cells as well as in transgenic and knock out mouse models in vivo. Our ultimate goal is to discover novel cell survival and death mediators that can be targeted for therapy in neurodegeneration and cancer.
