Despite global eradication efforts over the past century, malaria remains a devastating public health burden, causing almost half a million deaths annually (WHO, 2016). A detailed understanding of the mechanisms that control malaria infection has been hindered by technical challenges of studying a complex parasite life cycle in multiple hosts. While many interventions targeting the parasite have been implemented, the complex biology of

Distinct Transcriptome Profiles Of Gag-Specific Cd8+ T Cells Temporally Correlated With The Protection Elicited By Sivδnef Live Attenuated Vaccine, Wuxun Lu, Yanmin Wu, Fangrui Ma, R. Paul Johnson, Qingsheng Li

Nebraska Center for Virology: Faculty Publications

The live attenuated vaccine (LAV) SIVmac239Δnef (SIVΔnef) confers the best protection among all the vaccine modalities tested in rhesus macaque model of HIV-1 infection. This vaccine has a unique feature of time-dependent protection: macaques are not protected at 3±5 weeks post vaccination (WPV), whereas immune protection emerges between 15 and 20 WPV. Although the exact mechanisms of the time-dependent protection remain incompletely understood, studies suggested that both cellular and humoral immunities contribute to this time-dependent protection. To further elucidate the mechanisms of protection induced by SIVΔnef, we longitudinally compared the global gene expression profiles of SIV Gag-CM9+ CD8+ (Gag-specific CD8+) …

Chloroviruses Have A Sweet Tooth, James L. Van Etten, Irina V. Agarkova, David D. Dunigan, Michela Tonetti, Cristina De Castro, Garry A. Duncan

Nebraska Center for Virology: Faculty Publications

Chloroviruses are large double-stranded DNA (dsDNA) viruses that infect certain isolates of chlorella-like green algae. They contain up to approximately 400 protein-encoding genes and 16 transfer RNA (tRNA) genes. This review summarizes the unexpected finding that many of the chlorovirus genes encode proteins involved in manipulating carbohydrates. These include enzymes involved in making extracellular polysaccharides, such as hyaluronan and chitin, enzymes that make nucleotide sugars, such as GDP-L-fucose and GDP-D-rhamnose and enzymes involved in the synthesis of glycans attached to the virus major capsid proteins. This latter process differs from that of all other glycoprotein containing viruses that traditionally use …

Tryptophan 375 Stabilizes The Outer-Domain Core Of Gp120 For Hiv Vaccine Immunogen Design, Duoyi Hu, Dane Bowder, Wenzhong Wei, Jesse Thompson, Mark A. Wilson, Shi-Hua Xiang

Nebraska Center for Virology: Faculty Publications

The outer-domain core of gp120 may serve as a better HIV vaccine immunogen than the full-length gp120 because of its greater stability and immunogenicity. In our previous report, we introduced two disulfide bonds to the outer-domain core of gp120 to fix its conformation into a CD4-bound state, which resulted in a significant increase in its immunogenicity when compared to the wild-type outer-domain core. In this report, to further improve the immunogenicity of the outer-domain core based immunogen, we have introduced a Tryptophan residue at gp120 amino acid sequence position 375 (375S/W). Our data from immunized guinea pigs indeed shows a …

How To Explain Cancer To A Child And The Effects Of Coloring Therapy In Children With Cancer, Alexandra Mauer

Undergraduate Honors Thesis Collection

Did you know that doodling or coloring in a book can have significant therapeutic effects? It has been studied and proven that art therapy can help with anxiety, depression, and even some diseases such as cancer.1 Although coloring may not be able to cure cancer, it can make coping with it more manageable.1 When a child who has cancer is waiting to be seen in a doctor’s office or at the hospital, a coloring book can keep his or her mind off of the diagnosis, provide entertainment, and elicit a relaxing mindset. This coloring book could also have a storyline …

Assessment Of Coronary Artery Outward Remodeling In Consequence Of Excision Of Epicardial Adipose Tissue In Ossabaw Swine, Kelly Coderre

Undergraduate Honors Thesis Collection

Background

Coronary artery disease (CAD) results from the buildup of cholesterol, inflammatory factors, and proliferating smooth muscle cells within a vessel wall. This plaque impedes on the vessel lumen, decreasing the space through which blood can flow, leading to an array of complications in the human body. To offset these effects, the arterial wall undergoes outward remodeling, a compensatory physiologic phenomenon that blood vessels undertake when burdened with a blockage, such as CAD. In a previously conducted study, a coronary epicardial adipose tissue excision (cEATx) surgery was performed above the left anterior descending (LAD) in Ossabaw swine to investigate the …

Rare Presentation Of High Grade Retroperitoneal Angiosarcoma In A Patient Status Post Endovascular Aortic Repair (Evar), Jairo Espinosa M.D., Alan Hifko, Julia Miladore M.D., John T. Collins

Research Day

INTRODUCTION: Primary angiosarcoma of the aorta is a rare malignancy arising from the aorta’s endothelial lining. The most common presentation is claudication, however in the presence of an endograft a tumor originating in the aneurysmal sac may remain undetected and mimic common graft pathology. Diagnosis is typically delayed due to vague clinical presentation and imaging being indistinguishable from common complications of endografts such as leaks, infections or hematomas. We report a case of primary angiosarcoma of the aorta after endovascular repair of an abdominal aortic aneurysm. This case report describes the sixth case in the literature of primary angiosarcoma arising …

Mechanical Loading As Potential Treatment For Wnt Inhibitor Induced Bone Loss, Juraj Zahatnansky Md, Daniel Dick, Gabrielle Foxa, Robert Baker, Bart Williams Phd

Research Day

The Wnt signaling pathway has been shown to play a role in bone homeostasis and carcinogenesis. On the one hand, a decrease in signaling has been associated with a decrease in bone mass, on the other, an increase in signaling with cancer development. LGK974 is a Wnt signaling inhibitor currently being investigated as a potential cancer therapeutic agent. This molecule inhibits Porcupine, a transmembrane protein necessary for Wnt ligand secretion. In light of the above and based on our preliminary data, treatment with LGK974 leads to bone mass loss. Our investigation aims to address whether such bone loss can be …
