Brain Endothelial Cells As Phagocytes: Mechanisms And Implications, Rudy T. Chang, Mark J. Fisher, Rachita K. Sumbria

Pharmacy Faculty Articles and Research

Brain microvascular endothelial cells (BECs) lining the brain capillaries form the anatomical site of the blood-brain barrier (BBB), providing a highly selective barrier to support brain homeostasis and function. While the BBB acts as a barrier to immune cells and pathogens under normal conditions, BECs can facilitate their entry into the CNS via a phagocytosis-like mechanism. A similar process is now increasingly reported for a diverse set of cargos, resulting in the categorization of BECs as “non-professional” phagocytes and redefining the conventional view that these cells are functionally non-phagocytic. This review aims to summarize research demonstrating the capacity of BECs …

Takotsubo Cardiomyopathy: A Case Of The Broken Heart, Lilian Huynh, Kaylee Putney

Annual Research Symposium

Takotsubo cardiomyopathy (TC), or "broken heart syndrome," is a rare cardiac condition causing temporary left ventricular dysfunction due to severe stress. Though the exact cause is unclear, it mimics myocardial infarction and can lead to cardiogenic shock. Current treatment lacks specific guidelines and relies on heart failure protocols. We report a case of a patient with TC-induced cardiogenic shock, likely triggered by emotional stress. She required vasopressors, a percutaneous intervention, an Impella device, and guideline-directed medication therapies. This case underscores the significance of establishing guideline optimizations for managing TC and cardiogenic shock.

Brain Delivery Of Erythropoietin Results In A Significant Reduction Of Brain Aβ And Spatial Memory Deficits In The App Knock-In Mouse Model, Rudy Tieu Chang, Devaraj V. Chandrashekar, Grace-Ann Chuli Roules, Emi Iwasaki, Nataraj Jagadeesan, Rachita K. Sumbria

Pharmacy Faculty Articles and Research

Background

Although novel treatments for Alzheimer’s disease (AD) have begun to show modest therapeutic effects, agents that target hallmark AD pathology and offer neuroprotection are desired. Erythropoietin (EPO) is a glycoprotein hormone with neuroprotective effects but is faced with challenges including limited brain uptake and increased hematopoietic side effects with long-term dosing. Therefore, EPO has been modified and bound to a chimeric transferrin receptor monoclonal antibody (cTfRMAb); the latter shuttles EPO past the blood-brain barrier (BBB) into brain parenchyma and reduces its plasma exposure and potential for side effects. Our study sought to characterize the safety and pharmacokinetics (PK) of …
