Achieving Cell-Specific Delivery of Multiple Oligonucleotide Therapeutics with Aptamer Chimeras
(2012)Current standard cancer treatments such as chemotherapeutics, and radiation therapy are nearly as likely to kill the patient as cure the cancer. Therapies that have such a narrow window of efficacy are necessary for the ... -
Activation and Subversion of MDA5-Dependent Immune Responses by the Engineered Oncolytic Poliovirus PVSRIPO
(2018)Cancer-specific cytopathogenicity of oncolytic viruses is often defined by viralsensitivity to innate antiviral immune responses, e.g. type I Interferons (IFNs), limitingcytotoxicity to cells lacking these responses. However, ... -
Aminopeptidase-Dependent Modulation of Bacterial Biofilms by Pseudomonas aeruginosa Outer Membrane Vesicles
(2019)Pseudomonas aeruginosa, known as one of the leading causes of morbidity and mortality in cystic fibrosis (CF) patients, secretes a variety of virulence-associated proteases. These enzymes have been shown to contribute ... -
Analysis of the Interaction between Viruses, Mirnas and the Rnai Pathway
(2008-04-03)The microRNA (miRNA) and RNA interference (RNAi) pathways have recently emerged as an important aspect of virus-host cell interaction. This interaction can occur in several different ways and may favor either the virus or ... -
Antineoplastic Cytotoxicity and Immune Adjuvancy of a Recombinant Oncolytic Poliovirus
(2016)Our group has pioneered the development of a live-attenuated poliovirus, called PVSRIPO, for the purpose of targeting cancer. Despite clinical progress, the cancer selective cytotoxicity and immunotherapeutic potential of ... -
Cell Wall Lipids Promoting Host Angiogenesis During Mycobacterial Infection
(2018)Mycobacterial infection leads to the formation of characteristic immune cell aggregates called granulomas. In humans and animal models, tuberculous granuloma formation is accompanied by dramatic remodeling of host vasculature ... -
Cellular Responses to Lactic Acidosis in Human Cancers
(2010)The physiology of the tumor microenvironment is characterized by lower oxygen (hypoxia), higher lactate, extracellular acidosis and glucose starvation. We examined the global, transcriptional cellular responses to each of ... -
Cha-Cha-Cha: Variable Adhesive Activity of the <italic>Haemophilus</Italic> Cryptic Genospecies Trimeric Autotransporter Cha
(2009)Disease caused by the Gram-negative <italic>Haemophilus</italic> cryptic genospecies begins with colonization of the maternal genital or neonatal respiratory tract. The primary goal of this work was to identify and characterize ... -
Characterization of Host Factors and Anti-viral Compounds for Diverse Mosquito-borne Flaviviruses
(2016)Our ability to convert basic knowledge into robust anti-viral therapeutics requires discovery of novel host-virus interactions as well as an informed anti-viral discovery pipeline. We used a genome-scale RNAi-based screen ... -
Characterizing novel molecular regulators of antiviral gene expression
(2020)The intracellular innate immune response to viral infection is among the first lines of defense against these pathogens. For the early establishment of an antiviral cellular state and initiation of inflammatory responses, ... -
Characterizing Stress-Induced Outer Membrane Vesicle Production in Pseudomonas aeruginosa
(2013)As an opportunistic Gram-negative pathogen, Pseudomonas aeruginosa must be able to adapt to changes and survive stressors in its environment during the course of infection. To aid survival in the hostile host environment, ... -
Chemical and Microbial Regulation of Epithelial Homeostasis and Innate Immunity
(2019)The intestine is a multifunctional organ that must perform dichotomous roles in order to maintain health. While it is the primary site of absorption of dietary nutrients, it must also serve as a barrier to both the multitude ... -
Chlamydia Subversion of Host Lipid Transport: Interactions with Cytoplasmic Lipid Droplets
(2009)The <italic>Chlamydiaceae</italic> are Gram-negative, obligate intracellular bacteria that are significant pathogens of humans and animals. Intracellularly, the bacteria reside in a membrane-bound vacuole, called the inclusion, ... -
Chromatin Accessibility Dynamics Underlying Development and Disease
(2015)Despite a largely static DNA sequence, our genomes are incredibly malleable. Comparative studies of chromatin features between different cell types, tissues, and species have revealed tremendous differences in how the genome ... -
Concentration-dependent recruitment of mammalian odorant receptors
(2019)Deciphering natural odor plumes with dynamic changes in odor concentrations presents a common challenge to all animals. A fundamental challenge in studying the organization principles of the olfactory system to encode odor ... -
Cooption of Innate Immune Cells in Promoting and Combating Infections
(2018)The key components of innate immune defense to pathogens are various migratory as well as tissue resident innate immune cells, however, their interactions with pathogens as well as their immune-orchestrating roles are often ... -
Defining the Role of Antibodies in Protection Against Cytomegalovirus Acquisition and Congenital Disease for Rational Vaccine Design
(2018)Human cytomegalovirus (HCMV) is the most common cause of congenital infection worldwide, impacting 1 in 150 live-born infants. Children afflicted by congenital HCMV frequently suffer from lifelong, debilitating neurologic ... -
Defining the Role of Host Cell Chromatin Traps in Chlamydia trachomatis Pathogenesis
(2016)Chlamydia trachomatis (CT) is the most common bacterial agent of sexually transmitted infection and can cause damaging inflammation of the female reproductive tract. As an obligate intracellular pathogen, CT must exit exhausted ... -
Dengue Virus Host Factors
(2009)Dengue fever and dengue hemorrhagic fever are estimated to afflict 50-100 million people annually and are caused by one of the four serotypes of dengue virus. Dengue virus is carried and transmitted to humans by mosquitoes ... -
Diversity of Species and Sexual Reproduction in the Fungal Genus Cryptococcus
(2019)Speciation is a central mechanism of biological diversification. While speciation is well studied in plants and animals, in comparison, relatively little is known about speciation in fungi. One fungal model is the Cryptococcus ...
