Faculty, Staff and Student Publications

Neutrophils and neutrophil extracellular traps (NETs) contribute to early neuromyelitis optica (NMO) histopathology initiated by IgG targeting astrocytic aquaporin-4 (AQP4) water channels. Yet, the mechanisms underlying neutrophil recruitment and their pathogenic roles in disease progression remain unclear. To investigate molecular-cellular events preceding classical complement cascade activation in a mouse NMO model, we continuously infused, via spinal subarachnoid route, a non-complement-activating mouse monoclonal AQP4-IgG. Parenchymal infiltration of netting neutrophils containing C5a ensued with microglial activation and motor impairment but no blood-brain barrier leakage. Motor impairment and neuronal dysfunction both reversed when AQP4-IgG infusion stopped. Two-photon microscopy and electron microscopy-based reconstructions revealed …

Faculty, Staff and Student Publications

Background: Cancer is a systemic disease with most deaths attributed to metastatic burden. Primary and metastatic tumors, albeit at different anatomic locations, are interconnected through multiple biological processes. Pre-clinical and clinical observations of growth acceleration of metastases after surgery, or abscopal effects outside the radiation field are widely reported, yet reliably triggering favorable and avoiding unfavorable systemic responses remains an unmet clinical need. Understanding local and systemic tumor interaction dynamics will help guide future treatments.

Methods: We analyze the data of multiple in vivo tumor models. We formalize the systemic interplay of tumors as mathematical differential equation and calibrate parameters …

Huntington's disease (HD) is a neurodegenerative disorder caused by an abnormal CAG expansion in the Huntingtin (HTT) gene. Given its simple genetic cause but complex pathogenic mechanisms, interest in targeting HTT for HD treatment is growing, necessitating a clear understanding of HTT regulation. HTT protein primarily exists in a core complex with HAP40, forming a highly ordered structure with two large globular domains connected by a bridge. We previously demonstrated that HAP40 is conserved in

Carotid Endarterectomy Remains A Feasible Bailout For Progressive Disease After Transcarotid Artery Revascularization: A Case Report, Aidin Baghbani, Blaz Podgorsek, Jason B Storch, Gordon H Martin, Naveed U Saqib, Daniel G Miles

Faculty, Staff and Student Publications

Carotid endarterectomy (CEA) remains the gold standard for carotid revascularization, though transcarotid artery revascularization (TCAR) has emerged as a less invasive alternative. We present a 67-year-old man with prior bilateral TCAR who developed severe right internal carotid artery restenosis 14 months after the procedure. Imaging confirmed >80% stenosis due to progressive plaque burden compressing the stent. The patient underwent successful CEA with en bloc stent explant using a standard technique. Recovery was uneventful. This case demonstrates the technical feasibility and safety of surgical stent explant after TCAR and reinforces CEA as a reliable salvage strategy when stent failure or disease …

A Treat-To-Target Approach For Obesity Management: A Post Hoc Analysis Of The Surmount-5 Trial., Carel W Le Roux, Luca Busetto, Louis Aronne, Deborah Bade Horn, Georgios K Dimitriadis, Beverly Falcon, Luis-Emilio Garcia-Perez, Elisa Gomez Valderas, Theresa Hunter Gibble, Cagri Senyucel, Julia P Dunn

Faculty, Staff and Student Publications

Introduction: With new advancements in obesity medicine, clarity on goals and expectations for successful disease management is limited. This post hoc analysis assessed application of proposed treat-to-target (TtT) thresholds for obesity to the outcome measures of SURMOUNT-5, which randomised participants with obesity to tirzepatide or semaglutide.

Methods: The proportion of participants in each treatment group reaching proposed TtT thresholds for waist to height ratio (WHtR) < 0.53, body mass index (BMI) < 27 kg/m2, or a combination was evaluated. The associations between the thresholds and achieving low disease activity to remission (meeting goals for at least four of five defined cardiometabolic risk parameters) and normalisation or improvement in SF-36v2 physical component score (PCS) from baseline to week 72 were explored.

Results: About 23.1%-33.9% of participants treated with tirzepatide and 14.2%-20.7% treated with semaglutide reached the TtT thresholds, with greater weight reduction than the overall population. About 77% of participants who reached WHtR < 0.53 achieved low disease activity to remission, with an odds ratio of 2.31 (p < 0.001) compared to those who did not reach this target. The BMI threshold was not statistically associated with the assessed outcomes for SF-36v2 PCS.

Conclusion: In this …

Platelets Cause Microvascular Occlusion And Delayed Neurological Deficits After Subarachnoid Hemorrhage In Mice., Ari Dienel, Sung-Ha Hong, Kiara Torres, Kanako Matsumura, Jose Guzman, Peeyush Thankamani Pandit, Bibek Samal, Harveen Kaur, Samitha Nemirajaiah, Angelica Bernal, H Alex Choi, Louise D Mccullough, Spiros L Blackburn, Jaroslaw Aronowski, Devin W Mcbride

Faculty, Staff and Student Publications

After subarachnoid hemorrhage (SAH), some patients develop delayed neurological deficits (DND). Microthrombi are considered a contributing factor to DND, but clinical trials of antiplatelets had mixed results. Existing research suggests that platelets play a role in the etiology of DND, but no comprehensive study has tested causality between platelets and DND after SAH. Here we hypothesize that after SAH, platelet activation promotes microthrombi formation, occlusion of the brain microvasculature and contributes to DND, and that inhibiting platelet aggregation is a therapeutic strategy. Mice experiencing SAH were administered various interventions. The animals were subjected to stimulation of platelets, platelet depletion, or …
