Transcriptomic Profiling Of Thymic Dysregulation And Viral Tropism After Neonatal Roseolovirus Infection, Andrei Belean, Eden Xue, Benjamin Cisneros, Elisha D O Roberson, Michael A Paley, Tarin M Bigley

2020-Current year OA Pubs

INTRODUCTION: Herpesviruses, including the roseoloviruses, have been linked to autoimmune disease. The ubiquitous and chronic nature of these infections have made it difficult to establish a causal relationship between acute infection and subsequent development of autoimmunity. We have shown that murine roseolovirus (MRV), which is highly related to human roseoloviruses, induces thymic atrophy and disruption of central tolerance after neonatal infection. Moreover, neonatal MRV infection results in development of autoimmunity in adult mice, long after resolution of acute infection. This suggests that MRV induces durable immune dysregulation.

METHODS: In the current studies, we utilized single-cell RNA sequencing (scRNAseq) to study …

Loss Of Β-Cell Identity And Dedifferentiation, Not An Irreversible Process?, Sumit Patel, Maria S Remedi

2020-Current year OA Pubs

Type 2 diabetes (T2D) is a polygenic metabolic disorder characterized by insulin resistance in peripheral tissues and impaired insulin secretion by the pancreas. While the decline in insulin production and secretion was previously attributed to apoptosis of insulin-producing β-cells, recent studies indicate that β-cell apoptosis rates are relatively low in diabetes. Instead, β-cells primarily undergo dedifferentiation, a process where they lose their specialized identity and transition into non-functional endocrine progenitor-like cells, ultimately leading to β-cell failure. The underlying mechanisms driving β-cell dedifferentiation remain elusive due to the intricate interplay of genetic factors and cellular stress. Understanding these mechanisms holds the …

Case Report: Increased Efficacy Of Cetuximab After Pembrolizumab Failure In Cutaneous Squamous Cell Carcinoma, Renee Morecroft, Jordan Phillipps, Alice Zhou, Omar Butt, Karam Khaddour, Tanner Johanns, George Ansstas

2020-Current year OA Pubs

Immunotherapy is the first-line option for treating advanced cutaneous squamous cell carcinoma (cSCC). However, up to half of patients experience no benefit and treatment resistance, warranting newer therapeutic approaches. Combinatory approaches, including cetuximab, may help overcome immunotherapy resistance and improve response rates in advanced cSCC. We report three cases of metastatic cSCC that achieved significant clinical responses after cetuximab therapy following initial progression on pembrolizumab. We have retrospectively reviewed these cases at a single academic center between 2018 and 2023. All patients initially progressed on pembrolizumab, after which cetuximab (mono- or combination therapy) was added with two complete responses and …

Hormonal And Circuit Mechanisms Controlling Female Sexual Behavior, Sayaka Inoue

2020-Current year OA Pubs

Sexual behavior is crucial for reproduction in many animals. In many vertebrates, females exhibit sexual behavior only during a brief period surrounding ovulation. Over the decades, studies have identified the roles of ovarian sex hormones, which peak in levels around the time of ovulation, and the critical brain regions involved in the regulation of female sexual behavior. Modern technical innovations have enabled a deeper understanding of the neural circuit mechanisms controlling this behavior. In this review, I summarize our current knowledge and discuss the neural circuit mechanisms by which female sexual behavior occurs in association with the ovulatory phase of …

Negligence In Biomedical Research: An Anti-Racist Approach For Substance Use Researchers, Jonathan Lehman, Danniella Balangoy, Angie P Mejia, Carlos Cardenas-Iniguez, Scott Marek, Anita C Randolph

2020-Current year OA Pubs

Racism is embedded in the fabric of society at structural, disciplinary, hegemonic, and interpersonal levels, working as a mechanism that drives health disparities. In particular, stigmatized views of substance use get entangled with racialization, serving as a tool to uphold oppressive systems. While national health institutions have made commitments to dismantle these systems in the United States, anti-racism has not been integrated into biomedical research practice. The ways in which substance use researchers use and interpret race data-without engaging in structural racism as a mechanism of health inequity-can only be described as inadequate. Drawing upon concepts from the Public Health …

Traversing The Bench To Bedside Journey For Inkt Cell Therapies, Julie O'Neal, Melissa Mavers, Reyka G Jayasinghe, John F Dipersio

2020-Current year OA Pubs

Invariant natural killer T (iNKT) cells are immune cells that harness properties of both the innate and adaptive immune system and exert multiple functions critical for the control of various diseases. Prevention of graft-versus-host disease (GVHD) by iNKT cells has been demonstrated in mouse models and in correlative human studies in which high iNKT cell content in the donor graft is associated with reduced GVHD in the setting of allogeneic hematopoietic stem cell transplants. This suggests that approaches to increase the number of iNKT cells in the setting of an allogeneic transplant may reduce GVHD. iNKT cells can also induce …

2020-Current year OA Pubs

Dementia is characterized by a decline in memory and thinking that is significant enough to impair function in activities of daily living. Patients seen in dementia specialty clinics are highly heterogenous with a variety of different symptoms that progress at different rates. Recent research has focused on finding data-driven subtypes for revealing new insights into dementia's underlying heterogeneity, rather than assuming that the cohort is homogenous. However, current studies on dementia subtyping have the following limitations: (i) focusing on AD-related dementia only and not examining heterogeneity within dementia as a whole, (ii) using only cross-sectional baseline visit information for clustering …

Systematic Computer-Aided Disulfide Design As A General Strategy To Stabilize Prefusion Class I Fusion Proteins, Karen J Gonzalez, Kevin C Yim, Jorge C G Blanco, Marina S Boukhvalova, Eva-Maria Strauch

2020-Current year OA Pubs

Numerous enveloped viruses, such as coronaviruses, influenza, and respiratory syncytial virus (RSV), utilize class I fusion proteins for cell entry. During this process, the proteins transition from a prefusion to a postfusion state, undergoing substantial and irreversible conformational changes. The prefusion conformation has repeatedly shown significant potential in vaccine development. However, the instability of this state poses challenges for its practical application in vaccines. While non-native disulfides have been effective in maintaining the prefusion structure, identifying stabilizing disulfide bonds remains an intricate task. Here, we present a general computational approach to systematically identify prefusion-stabilizing disulfides. Our method assesses the geometric …

Sexual Dimorphism In Hepatic Ppar Alpha And Cyp4a12a Expression Is Associated With Reduced Development Of Drug-Induced Non-Alcoholic Steatohepatitis In Female Il-33-/- Mice, Chloe Thomas, Dolores B Njoku

2020-Current year OA Pubs

Males are at higher risk for developing metabolic dysfunction-associated steatohepatitis (MASH) than females; however, mechanisms mediating sexual dimorphism in MASH development are not completely understood. Nutrition-based mouse models suggest that dysregulated fatty acid biosynthesis promotes MASH. Drugs recapitulate MASH without diet variabilities. This brief report investigates associations of sexual dimorphism with male susceptibility to MASH utilizing a drug-induced MASH model and focuses on very-long-chain fatty acid biosynthesis pathways. We assessed male and female mouse livers at 5 and 15 weeks following MASH induction by immunizations and age-matched un-immunized controls utilizing Western blot. Our results suggest that PPAR alpha and CYP4a12a …
