Molecular Biology Of A Surface-Exposed Protein Family Of Bartonella Bacilliformis, Hannah Fay 2017 University of Montana

Molecular Biology Of A Surface-Exposed Protein Family Of Bartonella Bacilliformis, Hannah Fay

Undergraduate Theses and Professional Papers

Bartonella bacilliformis is a gram negative alpha-proteobacterium native to the Andes of South America. Bartonella causes Carrion’s disease, a potentially life threatening disease transmitted by the sand fly. It has a mortality rate of 88% when untreated and 10% when treated. Diagnostics and control measures for the disease are underdeveloped and no vaccine is available. Recent outbreaks indicate that the range of the pathogen is increasing with nearly 1.7 million people in western South America at risk. Little is known about the epidemiology and pathogenesis of B. bacilliformis. Recent research done by UC San Diego found a paralogous ...

Inflammasome activation is associated with numerous diseases. However, in vivo detection of the activated inflammasome complex has been limited by a dearth of tools. We have developed transgenic mice that ectopically express the fluorescent adaptor protein, apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) and characterized the formation of assembled inflammasome complexes ("specks") in primary cells and tissues. In addition to hematopoietic cells, we have found that a stromal population in the lung tissues formed specks during the early phase of influenza infection, whereas myeloid cells showed speck formation after 2 days. In a peritonitis and group B streptococcus ...


Human Monoclonal Antibodies To Plasmodium Falciparum Circumsporozoite Protein For Transient Passive Protection Of Malaria Travelers To Endemic Areas, Stuart Nelson, Douglas Golenbock, Ann M. Moormann, Colby A. Souders, Lisa Cavacini 2016 University of Massachusettts Medical School

Human Monoclonal Antibodies To Plasmodium Falciparum Circumsporozoite Protein For Transient Passive Protection Of Malaria Travelers To Endemic Areas, Stuart Nelson, Douglas Golenbock, Ann M. Moormann, Colby A. Souders, Lisa Cavacini

Ann M. Moormann

Plasmodium falciparum, is a protozoa that causes over 214 million cases of Malaria worldwide and the World Health Organization reported an estimated 438,000 deaths attributed to malaria in 2015. Current prevention strategies have reduced malaria cases but they are either costly, have poor efficacy or resistance has begun to develop. There is a global need for an effective pre-exposure prophylaxis treatment.

The leading Malaria vaccine candidate is RTS,S which contains a monovalent Plasmodium falciparum circumsporozoite protein (CSP). The goal of this vaccine is to induce anti-CSP antibodies that would block sporozoite invasion of hepatocytes and thereby hinder parasite ...


N-Methylation Of A Bactericidal Compound As A Resistance Mechanism In Mycobacterium Tuberculosis, Kenan C. Murphy, Carl F. Nathan 2016 University of Massachusetts Medical School

N-Methylation Of A Bactericidal Compound As A Resistance Mechanism In Mycobacterium Tuberculosis, Kenan C. Murphy, Carl F. Nathan

Open Access Articles

The rising incidence of antimicrobial resistance (AMR) makes it imperative to understand the underlying mechanisms. Mycobacterium tuberculosis (Mtb) is the single leading cause of death from a bacterial pathogen and estimated to be the leading cause of death from AMR. A pyrido-benzimidazole, 14, was reported to have potent bactericidal activity against Mtb. Here, we isolated multiple Mtb clones resistant to 14. Each had mutations in the putative DNA-binding and dimerization domains of rv2887, a gene encoding a transcriptional repressor of the MarR family. The mutations in Rv2887 led to markedly increased expression of rv0560c. We characterized Rv0560c as an S-adenosyl-L-methionine-dependent ...


Genomic Insights Into The Ixodes Scapularis Tick Vector Of Lyme Disease, Monika Gulia-Nuss,, Daniel R. Caffrey, Neal S. Silverman, Adam R. Wespiser, Catherine A. Hill 2016 Purdue University

Genomic Insights Into The Ixodes Scapularis Tick Vector Of Lyme Disease, Monika Gulia-Nuss,, Daniel R. Caffrey, Neal S. Silverman, Adam R. Wespiser, Catherine A. Hill

Neal Silverman

Ticks transmit more pathogens to humans and animals than any other arthropod. We describe the 2.1 Gbp nuclear genome of the tick, Ixodes scapularis (Say), which vectors pathogens that cause Lyme disease, human granulocytic anaplasmosis, babesiosis and other diseases. The large genome reflects accumulation of repetitive DNA, new lineages of retro-transposons, and gene architecture patterns resembling ancient metazoans rather than pancrustaceans. Annotation of scaffolds representing approximately 57% of the genome, reveals 20,486 protein-coding genes and expansions of gene families associated with tick-host interactions. We report insights from genome analyses into parasitic processes unique to ticks, including host 'questing ...

Cannabinoids Suppress The Innate Immune Response To Periodontal Pathogen Porphyromonas Gingivalis In Gingival Epithelial Cells., Rajarshi Guha Niyogi

Electronic Theses and Dissertations

Marijuana is widely used in the United States for recreational and medicinal purposes. Despite the proposed beneficial effects of cannabis on certain medical conditions, there is also a concern there is also a concern over negative health consequences of marijuana smoking. Recently, cannabis use has been established as a dose related risk factor for chronic periodontitis. Although the induction / exacerbation of chronic periodontitis in marijuana users has been established epidemiologically, the mechanisms underlying such predisposition are still unknown. It has long been suggested that marijuana has anti-inflammatory properties, while human epithelial cells are known to express cannabinoid receptor type 2 ...

Zika virus has emerged as a severe health threat with a rapidly expanding range. The IFITM family of restriction factors inhibits the replication of a broad range of viruses, including the closely related flaviruses West Nile virus and dengue virus. Here, we show that IFITM1 and IFITM3 inhibit Zika virus infection early in the viral life cycle. Moreover, IFITM3 can prevent Zika-virus-induced cell death. These results suggest that strategies to boost the actions and/or levels of the IFITMs might be useful for inhibiting a broad range of emerging viruses.

The flaviviruses dengue virus (DENV) and Zika virus (ZIKV) are severe health threats with rapidly expanding ranges. To identify the host cell dependencies of DENV and ZIKV, we completed orthologous functional genomic screens using RNAi and CRISPR/Cas9 approaches. The screens recovered the ZIKV entry factor AXL as well as multiple host factors involved in endocytosis (RAB5C and RABGEF), heparin sulfation (NDST1 and EXT1), and transmembrane protein processing and maturation, including the endoplasmic reticulum membrane complex (EMC). We find that both flaviviruses require the EMC for their early stages of infection. Together, these studies generate a high-confidence, systems-wide view of ...
