Age-related macular degeneration (AMD) has significant genetic component, yet monozygotic twins frequently exhibit discordance in disease status, highlighting the role of non-genetic factors. To enable comparative studies of AMD pathogenesis, we generated two induced pluripotent stem cell (iPSC) lines from peripheral blood mononuclear cells (PBMCs) of a monozygotic twin pair discordant for AMD. These iPSC lines offer a unique genetically matched resource to investigate molecular differences between affected and unaffected twins, as well as their responses to genetic, epigenetic, and environmental contributors to AMD development.

Validation Of An Assay For Ngal In A Pediatric Population, Nazmin Bithi, Ridwan B Ibrahim, Estella L Tam, Radwa Almamoun, Annette C Frenk Oquendo, Ayse Akcan-Arikan, Sridevi Devaraj

Faculty, Staff and Students Publications

Background and objectives: Acute kidney injury (AKI) poses a serious clinical challenge, particularly in high-risk environments, due to its association with increased morbidity and mortality. Traditional diagnostic markers, such as serum creatinine, often detect AKI only after significant kidney damage has occurred, limiting opportunities for early intervention. Neutrophil gelatinase-associated lipocalin (NGAL) has emerged as a promising early biomarker due to its rapid upregulation following kidney ischemia. NGAL supports renal recovery by reducing toxicity and promoting tubular regeneration via heme oxygenase-1 activity. This study aimed to validate the BioPorto ProNephro AKI™ turbidimetric immunoassay for urinary NGAL on the Ortho Vitros XT7600 …

Excision And Regional Flap Reconstruction With Radiation Therapy Of Granuloma Annulare Of The Digit: A Case Report, Austin Y Jiang, Linda K Green, David Netscher

Faculty, Staff and Students Publications

Granuloma annulare (GA) is a benign, often self-limited granulomatous skin condition that typically resolves spontaneously. Treatment is often not required, but topical and injectional corticosteroids are the most common interventions. Excision is effective for diagnosis and temporary treatment, but usually not considered curative. This case report describes the unconventional treatment of a recurrent biopsy-proven GA of the index finger. Due to the combination of the recalcitrant nodules interfering with function and patient preference, the nodules were excised multiple times. Ultimately requiring reconstruction with a pedicled radial forearm flap, the patient thereafter received radiation therapy to prevent recurrence, the combination of …

Faculty, Staff and Students Publications

Febrile infection-related epilepsy syndrome (FIRES) is a rare presentation of refractory status epilepticus following a febrile illness with resulting refractory epilepsy. Evidence supports the presence of immune dysregulation in patients with FIRES, but a monogenic basis for FIRES has not been identified in most cases. We present a case of a previously healthy 16-year-old male with FIRES who was found to have a de novo predicted damaging missense variant in CSF1R on clinical whole genome sequencing, a gene encoding a critical regulator of microglial homeostasis in which pathogenic variants cause adult onset leukoencephalopathy. Molecular modeling demonstrates that the CSF1R variant …

Spatial Omics Enters The Microscopic Realm: Opportunities And Challenges, Yichen Si, Joo Sang Lee, Goo Jun, Hyun Min Kang, Jun Hee Lee

Faculty, Staff and Students Publications

Spatial transcriptomics (ST) enables systematic profiling of whole-transcriptome gene expression in tissues while preserving spatial context. Recent advances in sequencing- and imaging-based ST technologies have ushered in the era of microscopic-resolution ST (μST), allowing transcriptome mapping at cellular and even subcellular scales with unprecedented precision. Despite these advances, μST faces substantial challenges, including sparse transcript discovery per submicron (or micron)-sized spatial units and data fragmentation across platforms, hindering integration and analysis. There is also a growing demand for scalable, segmentation-free, and universally applicable analysis methods, as well as strategies for 3D mapping, multi-omics integration, and artificial intelligence (AI)-driven spatial analysis. …

Focal Adhesion Kinase Drives Rho/Rock And Mtor Signaling To Protect And Augment Aortic Dissections, Zhen Zhou, Pujun Guan, Ripon Sarkar, Yang Yu, Alexis Richard, Dar Weiss, Yuki Kawamura, Chen Zhang, Yanming Li, Tomas Vaisar, Daniel R Martin, L Maximillian Buja, Zhouxuan Li, Kartik Venkatachalam, Ying H Shen, Scott A Lemaire, Jay D Humphrey, Dianna M Milewicz

Dysfunctional mechanosensing via focal adhesions (FAs) significantly contributes to thoracic aortic dissection in the β-aminopropionitrile mouse model by triggering FA kinase activation and subsequent Rho/ROCK and mTOR signaling pathways. The present findings indicate that these signaling pathways play distinct roles in ascending vs descending dissections. Specifically, in the ascending aorta, smooth muscle cell FA kinase-Rho/ROCK signaling acts as a beneficial adaptive mechanism to prevent dissections, whereas mTOR signaling is pathogenic and contributes to dissections.

A Divergent Cyclic Nucleotide Binding Protein Promotes Plasmodium Ookinete Infection Of The Mosquito, Dominika Kwecka, Zhishuo Wang, Edvardas Eigminas, Lijia Liu, Jennifer C Regan, Choel Kim, Nisha Philip

Faculty, Staff and Students Publications

Colonisation of mosquitos by the malarial parasite is critically reliant on the invasive ookinete stage. Ookinete invasion of mosquito is coordinated by the apical complex, a specialised parasite structure containing components for secretion, attachment and penetration. While studies have investigated cytoskeletal and secretory elements, it is currently unknown if signalling modules are present or functional at the apical complex. Here we elucidate the role of a cryptic cyclic nucleotide-binding protein which we name CBP-O. PbCBP-O showed a marked localisation to the ookinete apex and disruption of the protein severely compromised ookinete invasion of mosquitos. Domain dissection analysis revealed that the …

S1pr1 Regulates Lymphatic Valve Development And Tertiary Lymphoid Organ Formation In The Ileum, Xin Geng, Gwendalyn J Randolph, Et Al.

2020-Current year OA Pubs

Efficient lymph flow is ensured by lymphatic valves (LVs). The mechanisms that regulate LV development are incompletely understood. Here, we show that the deletion of the GPCR sphingosine 1-phosphate receptor-1 (S1PR1) from lymphatic endothelial cells (LECs) results in fewer LVs. Interestingly, LVs that remained in the terminal ileum-draining lymphatic vessels were specifically dysfunctional. Furthermore, tertiary lymphoid organs (TLOs) formed in the terminal ileum of the mutant mice. TLOs in this location are associated with ileitis in humans and mice. However, mice lacking S1PR1 did not develop obvious characteristics of ileitis. Mechanistically, S1PR1 regulates shear stress signaling and the expression of …
