Decomposing Differences In Coronavirus Disease 2019-Related Case-Fatality Rates Across Seventeen Nations, Ashley Wendell Kranjac, Dinko Kranjac Dec 2020

Decomposing Differences In Coronavirus Disease 2019-Related Case-Fatality Rates Across Seventeen Nations, Ashley Wendell Kranjac, Dinko Kranjac

Sociology Faculty Articles and Research

As of 1 November 2020, estimated case-fatality rates associated with coronavirus disease 2019 are not uniformly patterned across the world and differ substantially in magnitude. Given the global spatial heterogeneity in case-fatality rates, we applied the Blinder-Oaxaca regression decomposition technique to identify how putative sociodemographic, structural, and environmental sources influence variation in case-fatality rates. We show that compositional and associational differences in country-level risk factors explain a substantial proportion of the coronavirus disease 2019-related case-fatality rate gap across nations. Asian countries fair better vis-à-vis case-fatality rate differences mainly due to variation in returns to sociodemographic, structural, and environmental sources among …

Molecular Virology Of Kshv In The Lymphocyte Compartment—Insights From Patient Samples And De Novo Infection Models, Farizeh Aalam, Jennifer Totonchy

Pharmacy Faculty Articles and Research

The incidence of Kaposi’s sarcoma-associated herpesvirus (KSHV)-associated Kaposi Sarcoma has declined precipitously in the present era of effective HIV treatment. However, KSHV-associated lymphoproliferative disorders although rare, have not seen a similar decline. Lymphoma is now a leading cause of death in people living with HIV (PLWH), indicating that the immune reconstitution provided by antiretroviral therapy is not sufficient to fully correct the lymphomagenic immune dysregulation perpetrated by HIV infection. As such, novel insights into the mechanisms of KSHV-mediated pathogenesis in the immune compartment are urgently needed in order to develop novel therapeutics aimed at prevention and treatment of KSHV-associated lymphoproliferations. …

Pharmacy Faculty Articles and Research

The virion proteins of Kaposi sarcoma-associated herpesvirus (KSHV) were initially characterized in 2005 in two separate studies that combined the detection of 24 viral proteins and a few cellular components via LC-MS/MS or MALDI-TOF. Despite considerable advances in the sensitivity and specificity of mass spectrometry instrumentation in recent years, leading to significantly higher yields in detections, the KSHV virion proteome has not been revisited. In this study, we have re-examined the protein composition of purified KSHV virions via ultra-high resolution Qq time-of-flight mass spectrometry (UHR-QqTOF). Our results confirm the detection of all previously reported virion proteins, in addition to 17 …

Covid-19 Viral Testing Disparities In Los Angeles City, Laura Cyphers

Student Scholar Symposium Abstracts and Posters

Hispanic and Black communities have been disproportionately impacted by COVID-19-related morbidity and mortality (California Department of Public Health, 2020). Inequitable access to viral testing resources may have exacerbated these COVID-19-related racial and ethnic health disparities. For example, reports from the Los Angeles Department of Public Health revealed glaring viral testing disparities in April 2020 (early pandemic), with predominantly White communities in Los Angeles County receiving 65% more tests than Hispanic and Black communities. In response, California statewide testing was expanded for communities of color (Vann et al., 2020). To investigate access to viral testing in Los Angeles City, the current …

Despite 25 years of research, the basic virology of Kaposi Sarcoma Herpesviruses (KSHV) in B lymphocytes remains poorly understood. This study seeks to fill critical gaps in our understanding by characterizing the B lymphocyte lineage-specific tropism of KSHV. Here, we use lymphocytes derived from 40 human tonsil specimens to determine the B lymphocyte lineages targeted by KSHV early during de novo infection in our ex vivo model system. We characterize the immunological diversity of our tonsil specimens and determine that overall susceptibility of tonsil lymphocytes to KSHV infection varies substantially between donors. We demonstrate that a variety of B lymphocyte …


Cytokine-Targeted Therapeutics For Kshv-Associated Disease, Nedaa Alomari, Jennifer Totonchy Sep 2020

Cytokine-Targeted Therapeutics For Kshv-Associated Disease, Nedaa Alomari, Jennifer Totonchy

Pharmacy Faculty Articles and Research

Kaposi’s sarcoma-associated herpesvirus (KSHV) also known as human herpesvirus 8 (HHV-8), is linked to several human malignancies including Kaposi sarcoma (KS), primary effusion lymphoma (PEL), multicentric Castleman’s disease (MCD) and recently KSHV inflammatory cytokine syndrome (KICS). As with other diseases that have a significant inflammatory component, current therapy for KSHV-associated disease is associated with significant off-target effects. However, recent advances in our understanding of the pathogenesis of KSHV have produced new insight into the use of cytokines as potential therapeutic targets. Better understanding of the role of cytokines during KSHV infection and tumorigenesis may lead to new preventive or therapeutic …

Pharmacy Faculty Articles and Research

Non-invasive brain delivery of neurotherapeutics is challenging due to the blood-brain barrier. The revived interest in transferrin receptor antibodies (TfRMAbs) as brain drug-delivery vectors has revealed the effect of dosing regimen, valency, and affinity on brain uptake, TfR expression, and Fc-effector function side effects. These studies have primarily used monovalent TfRMAbs with a human constant region following acute intravenous dosing in mice. The effects of a high-affinity bivalent TfRMAb with a murine constant region, without a fusion partner, following extravascular dosing in mice are, however, not well characterized. Here we elucidate the plasma pharmacokinetics and safety of a high-affinity bivalent …

Asthma is the leading chronic condition amongst children in the United States as 7.5% of children are diagnosed with asthma. Studies have shown that positive social support is associated with positive asthma management. A strong social support system predicts good management of asthma symptoms; however, current literature has not yet examined how social support impacts lung function as opposed to merely symptom management. Stress and negative affect have been revealed to be associated with worse asthma control, as well as exacerbation of symptoms. Stressful situations, such as the death of a family member, unemployment, and familial tensions lead to worsening …

Phosphodiesterase Isoforms And Camp Compartments In The Development Of New Therapies For Obstructive Pulmonary Diseases, Martina Schmidt, Isabella Cattani-Cavalieri, Francisco J. Nuñez, Rennolds S. Ostrom

Pharmacy Faculty Articles and Research

The second messenger molecule 3′5′-cyclic adenosine monophosphate (cAMP) imparts several beneficial effects in lung diseases such as asthma, chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF). While cAMP is bronchodilatory in asthma and COPD, it also displays anti-fibrotic properties that limit fibrosis. Phosphodiesterases (PDEs) metabolize cAMP and thus regulate cAMP signaling. While some existing therapies inhibit PDEs, there are only broad family specific inhibitors. The understanding of cAMP signaling compartments, some centered around lipid rafts/caveolae, has led to interest in defining how specific PDE isoforms maintain these signaling microdomains. The possible altered expression of PDEs, and thus abnormal …

Pharmacy Faculty Articles and Research

"Alzheimer’s disease (AD) is the sixth leading cause of death in the United States with approximately 5.8 million Americans currently living with AD. Due to the lack of a disease modifying treatment for AD and the aging baby boomer generation, this number is projected to grow to 13.8 million by 2050 (Gaugler et al., 2019). Amyloid-beta (Aβ) plaque accumulation, one of the major pathological hallmarks of AD, can begin > 20 years before clinical symptoms of AD. By the time AD is clinically diagnosed, neuronal loss and neuropathological lesions (Aβ plaques and tau tangles) have already occurred in many brain regions …

Certain diseases, like colds, tend not to stop us. A paracetamol here, an ibuprofen there, and we are on the go. That is, until we, as a species, are faced with a virus that not only spreads through social contact, but has an estimated reproductive number of 2 to 2.5 and potentially kills 3–4% of those infected (WHO, 2020). To reduce transmission probability of COVID-19, governmental agencies around the world have recommended or enforced measures to decrease social contact; early evidence suggests these measures produce the intended effect (Kucharski et al., 2020).

Investigating The Interactions Between Individual Calmodulin And Hiv-1 Protein Domains, Riley K. Kendall, Jerry Larue

Student Scholar Symposium Abstracts and Posters

The World Health Organization found that 37.9 million people were living with HIV by the end of 2018. HIV is a virus that weakens the immune system through viral replication and the destruction of CD4+ T-cells, which are white blood cells that detect infection and make antibodies. A cure for HIV has not yet been discovered. HIV-1 contains a Gag polyprotein which regulates the stages of viral replication. Previous studies suggest that the myristoyl group of a matrix protein peptide found on the Gag polyprotein, MA, forms a complex with a calcium-binding, multifunctional regulatory protein called Calmodulin (CaM). CaM …
