Co-Option Of Mitochondrial Nucleic Acid-Sensing Pathways By Hsv-1 Ul12.5 For Reactivation From Latent Infection, Patryk A. Krakowiak, Matthew E. Flores, Sean R. Cuddy, Abigail L. Whitford, Sara A. Dochnal, Aleksandra Babnis, Tsuyoshi Miyake, Marco Tigano, Daniel A. Engel, Anna R. Cliffe

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Although viruses subvert innate immune pathways for their replication, there is evidence they can also co-opt antiviral responses for their benefit. The ubiquitous human pathogen, Herpes simplex virus-1 (HSV-1), encodes a protein (UL12.5) that induces the release of mitochondrial nucleic acid into the cytosol, which activates immune-sensing pathways and reduces productive replication in nonneuronal cells. HSV-1 establishes latency in neurons and can reactivate to cause disease. We found that UL12.5 is required for HSV-1 reactivation in neurons and acts to directly promote viral lytic gene expression during initial exit from latency. Further, the direct activation of innate immune-sensing pathways triggered …

Moud 2.0: A Clinical Algorithm And Implementation Evaluation Protocol For Sublingual And Injectable Buprenorphine Treatment Of Opioid Use Disorder, Brandon Joa, Eric Fung, Michael Weinstein, Lara Weinstein

Department of Family & Community Medicine Faculty Papers

BACKGROUND: Primary care is the initial contact point for most patients with opioid use disorder (OUD) but lacks tools for guiding treatment. Only a small fraction of patients access evidence-based care. Long-acting injectable buprenorphine has potential to improve medication adherence and program retention in low-barrier primary care treatment settings. We present the first clinical decision support algorithm incorporating long-acting buprenorphine (LAIB) in primary care. We include a protocol for a future evaluation of the algorithm's implementation process, "Medication for Opioid Use Disorder (MOUD) 2.0," at a housing and integrated care clinic at a Federally Qualified Health Center.

Il-1Β In Neoplastic Disease And The Role Of Its Tumor-Derived Form In The Progression And Treatment Of Metastatic Prostate Cancer, Yetunde Oyende, Luke Taus, Alessandro Fatatis

Kimmel Cancer Center Faculty Papers

Since its discovery, IL-1β has taken center stage as a key mediator of a very broad spectrum of diseases revolving around immuno-mediated and inflammatory events. Predictably, the pleiotropic nature of this cytokine in human pathology has led to the development of targeted therapeutics with multiple treatment indications in the clinic. Following the accumulated findings of IL-1β's central modulatory role in the immune system and the implication of inflammatory pathways in cancer, the use of IL-1β antagonists was first proposed and then also pursued for oncology disorders. However, this approach has consistently relied on the perceived need of interfering with IL-1β …

Transcription Factor Runx1 Regulates Coagulation Factor Xiii-A (F13a1): Decreased Platelet-Megakaryocyte F13a1 Expression And Clot Contraction In Runx1 Haplodeficiency, Fabiola Del Carpio-Cano, Natthapol Songdej, Liying Guan, Guangfen Mao, Lawrence E. Goldfinger, Jeremy G.T. Wurtzel, Kiwon Lee, Michele P. Lambert, Mortimer Poncz, A. Koneti Rao

Cardeza Foundation for Hematologic Research

BACKGROUND: Germline RUNX1 haplodeficiency (RHD) is associated with thrombocy- topenia, platelet dysfunction, and predisposition to myeloid malignancies. Platelet expression profiling of an RHD patient showed decreased F13A1, encoding for the A subunit of factor (F)XIII, a transglutaminase that cross-links fibrin and induces clot stabilization. FXIII-A is synthesized by hematopoietic cells, megakaryocytes, and monocytes.

OBJECTIVES: o understand RUNX1 regulation of F13A1 expression in platelets/mega- karyocytes and the mechanisms and consequences of decreased F13A1 in RHD.

METHODS: We performed studies in platelets, human erythroleukemia (HEL) cells, and human CD34+ cell-derived megakaryocytes including on clot contraction in cells following small inhibitor RNA knockdown …

Adenosine-Sensitive Upper Septal Fascicular Ventricular Tachycardia Associated With Takotsubo Syndrome, Parker O'Neill, Daniel Underberg, Reginald Ho, Darius Farzad, Gregary Marhefka

Department of Medicine Faculty Papers

We describe a rare case of upper septal fascicular ventricular tachycardia (VT) associated with takotsubo syndrome that failed to convert with synchronized shock but converted to normal sinus rhythm after intravenous adenosine administration. The excess catecholamine state of takotsubo syndrome likely provided substrate for cyclic adenosine monophosphate–mediated triggered activity, causing fascicular VT.

A Proposed Mhealth Intervention To Address Patient Barriers To Colposcopy Attendance: Qualitative Interview Study Of Clinic Staff And Patient Perspectives, Jennifer Hemler, Rachel Wagner, Brittany Sullivan, Myneka Macenat, Erin Tagai, Jazmarie Vega, Enrique Hernandez, Suzanne Miller, Kuang-Yi Wen, Charletta Ayers, Mark Einstein, Shawna Hudson, Racquel Kohler

Department of Medical Oncology Faculty Papers

BACKGROUND: Cervical cancer disparities persist among minoritized women due to infrequent screening and poor follow-up. Structural and psychosocial barriers to following up with colposcopy are problematic for minoritized women. Evidence-based interventions using patient navigation and tailored telephone counseling, including the Tailored Communication for Cervical Cancer Risk (TC3), have modestly improved colposcopy attendance. However, the efficacious TC3 intervention is human resource-intense and could have greater reach if adapted for mobile health, which increases convenience and access to health information.

OBJECTIVE: This study aimed to describe feedback from clinic staff members involved in colposcopy processes and patients referred for colposcopy regarding adaptions …

BACKGROUND: In recent years, many studies have demonstrated the efficacy of an early switch to oral antibiotics after surgical treatment in orthopedic-related infections. However, large analyses on periprosthetic joint infections (PJIs) are lacking.

MATERIAL AND METHODS: We conducted a retrospective observational multicenter study in patients diagnosed with an early post-operative PJI, defined as one occurringdebridement, antibiotics, and implant retention (DAIR). Patients from Europe and the USA were included. We took advantage of the fact that an early oral antibiotic switch is routine practice in Europe as opposed to a long duration of intravenous (IV) antibiotic treatment in the USA. Failure …

Skeletal And Dental Tissue Mineralization: The Potential Role Of The Endoplasmic Reticulum/Golgi Complex And The Endolysosomal And Autophagic Transport Systems, Irving M. Shapiro, Makarand V. Risbud, Tengteng Tang, William J. Landis

Department of Orthopaedic Surgery Faculty Papers

This paper presents a review of the potential role of the endoplasmic reticulum/Golgi complex and intracellular vesicles in mediating events leading to or associated with vertebrate tissue mineralization. The possible importance of these organelles in this process is suggested by observations that calcium ions accumulate in the tubules and lacunae of the endoplasmic reticulum and Golgi. Similar levels of calcium ions (approaching millimolar) are present in vesicles derived from endosomes, lysosomes and autophagosomes. The cellular level of phosphate ions in these organelles is also high (millimolar). While the source of these ions for mineral formation has not been identified, there …

Department of Surgery Faculty Papers

Individuals with chronic inflammatory and immune disorders are at an increased risk of atherosclerotic events and premature cardiovascular (CV) disease. Despite extensive literature exploring the relationship between "non-traditional" atherosclerotic conditions and CV risk, many aspects remain unresolved, including the underlying mechanisms promoting the "non-traditional CV risk", the development of an innovative and comprehensive CV risk assessment tool, and recommendations for tailored interventions. This review aims to evaluate the available evidence on key "non-traditional" CV risk-enhancer conditions, with a focus on assessing and managing CV risk factors. We conducted a comprehensive review of 412 original articles, narrative and systematic reviews, and …

Perinuclear Organelle Trauma At The Nexus Of Cardiomyopathy Pathogenesis Arising From Loss Of Function Lmna Mutation, Jason C. Choi

Center for Translational Medicine Faculty Papers

Over the past 25 years, nuclear envelope (NE) perturbations have been reported in various experimental models with mutations in the LMNA gene. Although the hypothesis that NE perturbations from LMNA mutations are a fundamental feature of striated muscle damage has garnered wide acceptance, the molecular sequalae provoked by the NE damage and how they underlie disease pathogenesis such as cardiomyopathy (LMNA cardiomyopathy) remain poorly understood. We recently shed light on one such consequence, by employing a cardiomyocyte-specific Lmna deletion in vivo in the adult heart. We observed extensive NE perturbations prior to cardiac function deterioration with collateral damage in the …

Department of Neurosurgery Faculty Papers

Pediatric low-grade gliomas (pLGGs) exhibit heterogeneous prognoses and variable responses to treatment, leading to tumor progression and adverse outcomes in cases where complete resection is unachievable. Early prediction of treatment responsiveness and suitability for immunotherapy has the potential to improve clinical management and outcomes. Here, we present a radiogenomic analysis of pLGGs, integrating MRI and RNA sequencing data. We identify three immunologically distinct clusters, with one group characterized by increased immune activity and poorer prognosis, indicating potential benefit from immunotherapies. We develop a radiomic signature that predicts these immune profiles with over 80% accuracy. Furthermore, our clinicoradiomic model predicts progression-free …
