Type 2-Low Asthma: Epidemiology, Multiomics, And Emerging Therapies, Philip Mendez, Alanis Rosado, Juan Carlos Cardet

Department of Pediatrics Faculty Publications

Purpose of Review

Type 2-low (T2-low) asthma, characterized by low blood and sputum eosinophils and low fractional exhaled nitric oxide (FeNO), remains a major unmet need because of frequent corticosteroid insensitivity and a lack of targeted therapies. This review summarizes recent advances in its epidemiology, multiomics, and therapeutic landscape.

Recent findings

T2-low inflammation is highly prevalent, affecting approximately 14%-39% of adults with current asthma and up to 60% of children. Its pathogenesis reflects complex non-T2 mechanisms, including IL-17 signaling, innate immune activation through IL-1β and IL-33, and neutrophilic inflammation. Heterogeneity is further shaped by systemic factors such as obesity and …

Synthesis And Characterization Of Succinate Dehydrogenase Inhibitors H2/Z14 And C6/Z96 In Order To Combat Small Cell Lung Cancer, Lauren M. Graves

Honors Undergraduate Theses

The use of ubiquinone inhibitors to combat cancer is a recent development in medicinal science and procedures to efficiently synthesize these drugs remain limited. C6/Z96 and H2/Z14, two succinate dehydrogenase inhibitors, have been previously tested in vitro against NSCLC with positive results. Their similarity to ubiquinone is what makes them a strong candidate for a succinate dehydrogenase inhibitor at the ubiquinone binding site. The heterocyclic scaffolds and substituents are proposed to bind strongly through a combination of electronics, hydrogen-bonding, and fit, allowing them to bind well and prove to be more favorable than ubiquinone when competing for the Q-site. By …

Senescent Fibroblasts In Aging And Pulmonary Fibrosis, Sara B. Palega, Aiwei Y. Borengasser, Yan Y. Sanders

Microbiology & Molecular Cell Biology Faculty Publications

Aging is a major risk factor for many chronic lung diseases, including Idiopathic Pulmonary Fibrosis (IPF), a fatal and incurable disease characterized by progressive fibrotic remodeling. Age-associated structural alterations, impaired regenerative capacity, and dysregulated cellular signaling collectively create a pro-fibrotic microenvironment. A central driver of this pathological shift is the accumulation of senescent cells, which undergo irreversible growth arrest and develop a robust pro-inflammatory senescence-associated secretory phenotype (SASP). Emerging evidence identifies senescent lung fibroblasts as critical mediators of IPF pathogenesis. These cells promote excessive extracellular matrix deposition, myofibroblast differentiation, and tissue stiffening, while simultaneously impairing epithelial regeneration. Together, these effects …

Deletion Of Stim1 In Treg Cells Protects Against Lung Fibrosis And Associated Cardiovascular Complications In A Pre-Clinical Mouse Model, Nagaraja Nagre, Balaji Srinivas, Nicholas Richards, Ryan Washington, Gregory Nicholson, Yan Sanders, Beata Kosmider, Khalid Matrougui

Department of Biomedical and Translational Sciences Faculty Publications

Idiopathic pulmonary fibrosis (IPF) is a progressive and incurable lung disease characterized by excessive tissue remodeling and impaired gas exchange. Evidence highlights the critical interplay between immune regulation, calcium signaling, and redox biology implications in the pathogenesis of fibrotic lung disease. Regulatory T-cells (Tregs), known to modulate cardiovascular and immune function, are diminished in IPF, contributing to inflammation and tissue damage. Here, we demonstrate that the stromal interaction molecule 1 (STIM1), a key regulator of intracellular calcium homeostasis, is significantly upregulated in Treg cells isolated from IPF patients and mice subjected to bleomycin-induced lung injury. This upregulation is associated with …

Systemic Sclerosis-Associated Interstitial Lung Disease: Improved Understanding And Advances In Management, Amit Syal, Chris T. Derk

Student Papers, Posters & Projects

Interstitial lung disease (ILD), a common manifestation of systemic sclerosis (SSc), has the highest organ-specific morbidity and mortality, particularly in patients with diffuse cutaneous SSc (dcSSc). Recent advances in diagnostics-including artificial intelligence (AI)-enhanced high-resolution computed tomography (HRCT) and biomarkers such as Krebs van den Lungen (KL)-6-have enabled earlier detection and monitoring of disease progression. Therapeutically, the approval of antifibrotics like nintedanib (NINT) and immunomodulators such as tocilizumab (Toci) has significantly expanded treatment options. Updated international guidelines from the American College of Rheumatology (ACR), American College of Chest Physicians (CHEST), American Thoracic Society (ATS), and European league against Rheumatism (EULAR) now …

The Loss Of Meg3 Causes Abnormal Alveolar Epithelial Progenitor Cell Differentiation, Arlo Colvard, Gianluca Digiovanni, Isabella Gaona, Sergey S. Gutor, Ujjal Singha, Taylor P. Sherrill, David S. Nichols, Yunli Zhou, Jonathan A. Kropski, Jason J. Gokey

Student Scholar Symposium

Idiopathic pulmonary fibrosis (IPF) is an interstitial lung disease (ILD) characterized by excessive extracellular matrix (ECM) deposition. The prognosis of IPF is poor, with the only curative option for the disease being lung transplantation. Prior studies have described increased expression of the lncRNA Meg3 in the lungs of IPF patients. Increased expression of Meg3 is associated with impaired lung repair through inhibition of lung basal progenitor cell differentiation. In this study, the lung alveolar epithelium was investigated in murine models of IPF and organoid culture. Lineage tracing and immunofluorescence confocal microscopy techniques were employed to identify the cell fate of …

Urinothorax And Empyema: Presentation Of An Unusual Complication Of A Rare Condition, Nolan Fox, Nicholas Fox, Shourjo Chakravorty, Neeraj Sinha

Division of Pulmonary, Allergy, and Critical Care Medicine Faculty Papers

A 68-year-old male with a history of metastatic bladder cancer and urinary obstruction presented with intractable hiccups and chest pain is presented in this case. He was found to have a unilateral pleural effusion in addition to ipsilateral renal metastasis abutting the diaphragm. Imaging revealed empyema. Thoracentesis revealed positive cultures and a lack of malignant cells on cytology. Comorbid urinary obstruction and urinary tract infection suggested the rare diagnosis of an infected urinothorax. Thoracentesis also revealed pleural fluid creatinine greater than serum creatinine, meeting the most specific diagnostic criteria for urinothorax and establishing the diagnosis. Treatment aimed at evacuating the …

Dermal Lymphatic Carcinomatosis As A Cutaneous Metastasis From Epidermal Growth Factor Receptor-Positive Lung Adenocarcinoma: A Case Report, Sarah A. Hemelt, Jonathan M. Joseph, Nicholas Culotta

School of Medicine Faculty Publications

Cutaneous metastases are an uncommon but clinically significant manifestation of internal malignancies. We present a rare case of dermal lymphatic carcinomatosis arising from epidermal growth factor receptor (EGFR)-positive lung adenocarcinoma, a presentation that may closely mimic inflammatory dermatoses and indicate therapeutic resistance or disease progression. We describe the clinical course of a 65-year-old woman who developed a violaceous cutaneous metastatic lesion beneath the left breast during treatment for metastatic lung adenocarcinoma. This case highlights the importance of recognizing cutaneous signs as indicators of disease progression and emphasizes the diagnostic challenges and prognostic implications of cutaneous metastases in lung cancer.

School of Medicine Faculty Publications

Introduction: There are no treatments directly targeting the pulmonary vasculature in chronic obstructive pulmonary disease (COPD), and further characterization of the underlying endothelial cell (EC) abnormalities could be helpful in drug development. Methods: We investigated the influence of exercise and the prostacyclin analog iloprost on extracellular vesicles derived from ECs (eEVs) in 15 moderate–severe COPD patients who were enrolled in a randomized, placebo-controlled crossover trial of iloprost. Results: Active smokers had a profile consistent with inflammatory-derived EVs, while exacerbation-prone COPD subjects had a profile consistent with apoptosis-derived eEVs. There were no significant effects of iloprost on eEV levels. However, there …
