Immunotherapy efficacy is limited in melanoma, and combinations of immunotherapies with other modalities have yielded limited improvements but also adverse events requiring cessation of treatment. In addition to ineffective patient stratification, efficacy is impaired by paucity of intratumoral immune cells (itICs); thus, effective strategies to safely increase itICs are needed. We report that dietary administration of l-fucose induces fucosylation and cell surface enrichment of the major histocompatibility complex (MHC)-II protein HLA-DRB1 in melanoma cells, triggering CD4+ T cell-mediated increases in itICs and anti-tumor immunity, enhancing immune checkpoint blockade responses. Melanoma fucosylation and fucosylated HLA-DRB1 associate with intratumoral T cell abundance …

Paxlovid-Induced Tacrolimus Toxicity In The Treatment Of Covid-19: A Case Report., Stephanie Michael, Rachel Heilbronner, Christopher M Lloyd, Howard W Levitin

Pharmacy Articles

Paxlovid^TM (nirmaltrelvir/ritonavir) received emergency use authorization from the Food and Drug Administration (FDA) in December 2021 to treat coronavirus disease 2019 (COVID-19). Given the actions of Paxlovid on cytochrome P450-3A4 (CYP3A4) enzymes, it is imperative to check for potential drug-drug interactions before prescribing. We describe a case in which the common emergency department presentation of generalized weakness was found to be caused by interactions between Paxlovid and a patient's home medications resulting in tacrolimus toxicity.

Colorblind Nationalism And The Limits Of Citizenship, Ming Hsu Chen

Cardozo Law Review

Policymakers and lawyers posit formal citizenship as the key to inclusion. Rather than presume that formal citizenship will necessarily promote equality, this Article examines the relationship between citizenship, racial equality, and nationalism. It asks: What role does formal citizenship play in excluding noncitizens and Asian, Latinx, and Muslim citizens racialized as foreigners? What effects does it have on the meaning of being American as a non-White citizen? The Article argues that commitments to colorblind equality and democratic self-governance of the nation stand in contradiction to aspirations to protect all persons within the nation. Consequently, individual rights designed to remedy racial …

Faculty, Staff and Students Publications

Acute aortic dissection is one of the most lethal diseases, affecting the lining of the aortic wall. We describe a case of Stanford Type A aortic dissection in a patient with underlying primary antiphospholipid syndrome (APS) complicated by coronavirus disease 2019 (COVID-19). APS is characterized by recurrent venous and/or arterial thrombosis, thrombocytopenia, and rarely vascular aneurysms. The hypercoagulable milieu attributable to APS and the prothrombotic state from COVID-19 posed a challenge in achieving optimal postoperative anticoagulation in our patient.

Pd-L1 Translocation To The Plasma Membrane Enables Tumor Immune Evasion Through Mib2 Ubiquitination, Xinfang Yu, Wei Li, Haidan Liu, Xu Wang, Cristian Coarfa, Chao Cheng, Xinlian Yu, Zhaoyang Zeng, Ya Cao, Ken H Young, Yong Li

Faculty, Staff and Students Publications

Programmed death-ligand 1 (PD-L1), a critical immune checkpoint ligand, is a transmembrane protein synthesized in the endoplasmic reticulum of tumor cells and transported to the plasma membrane to interact with programmed death 1 (PD-1) expressed on T cell surface. This interaction delivers coinhibitory signals to T cells, thereby suppressing their function and allowing evasion of antitumor immunity. Most companion or complementary diagnostic devices for assessing PD-L1 expression levels in tumor cells used in the clinic or in clinical trials require membranous staining. However, the mechanism driving PD-L1 translocation to the plasma membrane after de novo synthesis is poorly understood. Herein, …

Broad Protective Vaccination Against Systemic Escherichia Coli With Autotransporter Antigens, Yikun Xing, Justin R Clark, James D Chang, Dylan M Chirman, Sabrina Green, Jacob J Zulk, Joseph Jelinski, Kathryn A Patras, Anthony W Maresso

Faculty, Staff and Students Publications

Extraintestinal pathogenic Escherichia coli (ExPEC) is the leading cause of adult life-threatening sepsis and urinary tract infections (UTI). The emergence and spread of multidrug-resistant (MDR) ExPEC strains result in a considerable amount of treatment failure and hospitalization costs, and contribute to the spread of drug resistance amongst the human microbiome. Thus, an effective vaccine against ExPEC would reduce morbidity and mortality and possibly decrease carriage in healthy or diseased populations. A comparative genomic analysis demonstrated a gene encoding an invasin-like protein, termed sinH, annotated as an autotransporter protein, shows high prevalence in various invasive ExPEC phylogroups, especially those associated with …

Genomic Or Non-Genomic? A Question About The Pleiotropic Roles Of Vitamin D In Inflammatory-Based Diseases, Michael F. Holick, Luciana Mazzei, Sebastián García Menéndez, Virna Margarita Martín Giménez, Fatme Al Anouti, Walter Manucha

All Works

Vitamin D (vit D) is widely known for its role in calcium metabolism and its importance for the bone system. However, various studies have revealed a myriad of extra-skeletal functions, including cell differentiation and proliferation, antibacterial, antioxidant, immunomodulatory, and anti-inflammatory properties in various cells and tissues. Vit D mediates its function via regulation of gene expression by binding to its receptor (VDR) which is expressed in almost all cells within the body. This review summarizes the pleiotropic effects of vit D, emphasizing its anti-inflammatory effect on different organ systems. It also provides a comprehensive overview of the genetic and epigenetic …

Considering Vaccination Status, Govind Persad

UC Law Journal

This Article examines whether policies—sometimes termed “vaccine mandates” or “vaccine requirements”— that consider vaccination status as a condition of employment, receipt of goods and services, or educational or other activity for participation are legally permitted, and whether such policies may even sometimes be legally required. It does so with particular reference to COVID-19 vaccines.

Part I explains the legality of private actors, such as employers or private universities, considering vaccination status, and concludes that such consideration is almost always legally permissible unless foreclosed by specific state legislation. Part II examines the consideration of vaccination status by state or federal policy. …

De La Cruz, Cory T. Overton, Laurie A. Hall, Elliott L. Matchett, Joshua T. Ackerman, Jeffery D. Sullivan, Andrew M. Ramey, Diann J. Prosser

Faculty Research, Scholarly, and Creative Activity

Understanding relationships between infection and wildlife movement patterns is important for predicting pathogen spread, especially for multispecies pathogens and those that can spread to humans and domestic animals, such as avian influenza viruses (AIVs). Although infection with low pathogenic AIVs is generally considered asymptomatic in wild birds, prior work has shown that influenza-infected birds occasionally delay migration and/or reduce local movements relative to their uninfected counterparts. However, most observational research to date has focused on a few species in northern Europe; given that influenza viruses are widespread globally and outbreaks of highly pathogenic strains are increasingly common, it is important …

Dissertations, Theses, and Capstone Projects

Diastereoselectivity of fluorination of a carbanion alpha to a sulfone in enantiomerically pure N-Boc protected (R)- and (S)-2,2-dimethyl-4-((arylsulfonyl)methyl)oxazolidines has been studied. Fluorination proceeded with good to excellent diastereoselectivity, which was base-dependent and was highest with lithium diisopropylamide (LDA). Diastereoselectivity also depended on the aryl moiety of the aryl sulfone and was highest with benzothiazole-derived sulfones. Under basic conditions, epimerization at the C–F stereogenic center alpha to the sulfone has been achieved for the first time and proceeded with good to excellent diastereoselectivity, which was highest in the case of a benzothiazole sulfone and with a lithium base. …

Tgf-B Signaling Mechanisms In Caenorhabditis Elegans Response To Bacterial Pathogens, Emma J. Ciccarelli

Dissertations, Theses, and Capstone Projects

When exposed to infection, the nematode C. elegans mounts an innate immune response through secretion of antimicrobial peptides (AMPs). Different signaling pathways in the worm regulate release of these AMPs. One highly conserved pathway is the C. elegans BMP like pathway – regulated by the ligand DBL-1. The DBL-1 pathway is noted for its significant role in development but has also been shown to regulate many post-developmental processes within the worm, including the immune response. We are interested in determining how DBL-1 signaling can mediate a response specific to immunity, separate from its other functions in the worm. Through survival …

The Immune Modulation On Innate Immunity, From Pathogen Recognition To Fungal Clearance., Ko-Wei Liu

Dartmouth College Ph.D Dissertations

The human lung is not sterile but a complex environment with various microorganisms. Besides commensals in the lung, hundreds to thousands of individual microbiomes enter the lung every day but without causing the symptom. Host innate immunity plays an important role in maintaining homeostasis of the lung environment and as the first defense line against pathogens. Aspergillus fumigatus (A. fumigatus) is a saprophytic filamentous fungus that can cause human disease in immune compromised patients. However, with functional innate immunity, immune cells can quickly recognize pathogen associated molecular patterns (PAMPs) from A. fumigatus through pattern recognition receptors (PRRs). The activation of …
