Inhibition of PDE4 and PI3Kδ in Addition to Stimulation of Nuclear Hormone Receptor PPAR in Emphysema Caused By Smoking

June 29, 2022 Haani Tai
Haani Tai Introduction. Smoking-related emphysema induces a disruption to many cellular signaling pathways especially related to inflammation. With inhibition of Phosphoinositide 3-kinase δ (PI3Kδ) showing promising results for reducing inflammation as well as agonizing peroxisome proliferator-activated receptor γ (PPARγ) to induce an anti-inflammatory response and prevent a proinflammatory response.1 Methods. Two…

Mesenchymal Stem Cells as a Treatment for Acute Respiratory Distress Syndrome

June 24, 2022 Michael Biskup
Michael Biskup Introduction. Acute Respiratory Distress Syndrome (ARDS) is an inflammatory reaction of the lungs to cellular damage. ARDS commonly develops after trauma, infection, pleuritis, and aspiration. Hypoxemic respiratory failure is a defining characteristic. In the beginning stages of ARDS, the body releases inflammatory mediators such as IL-1. Neutrophils then…

Exploration of Novel Anti-Quorum Sensing Compounds in Pseudomonas Aeruginosa Inhabited Cystic Fibrosis Patients

June 1, 2022 Karan Hooda
Karan Hooda Introduction. Cystic Fibrosis (CF) is a genetic disorder in which there is a deletion of F508 in the cystic fibrosis transmembrane conductance regulator gene (CFTR).1 This leads to mucus buildup and dehydration of respiratory airway surfaces, providing the optimal environment for pathogens to inhabit.2 Pseudomonas aeruginosa is a…

Mesenchymal Stem Cells Suppress T-Cell Activation/Proliferation via PD-1/PD-L1 in Fibrotic Conditions such as Systemic Sclerosis.

August 5, 2021 James Risinger
James Risinger Introduction. Systemic sclerosis (SSc) is an immune-mediated that is uncommon, but has a high morbidity and mortality1. The common clinical presentation of SSc includes perioral soft tissue loss, sclerodactyly, facial telangiectasis, dilated nail-fold capillaries, extensive calcinosis cutis1. Interstitial lung disease (ILD) is a common complication of systemic sclerosis and the…

The Role of WNT5a as a Regulator of Cystic Airspace Enlargement in Pulmonary Lymphangioleiomyomatosis

July 28, 2021 Ashley Kidwell
Ashley Kidwell Introduction. Pulmonary lymphangioleiomyomatosis (LAM) is a rare, lymphatic disease that affects 5-9 million women of child-bearing age.1,2 This is the second leading cause of mortality in women with tuberous sclerosis.3 Pulmonary LAM begins with a loss of function mutation in tuberous sclerosis complex 2 (Tsc2).1 This removes its…

The Underlying Mechanisms of Thoracic Radiation Therapy Induced Lung Diseases: Extracellular Adenosine Production by CD73

July 25, 2019 Tasfia Rouf
Tasfia Rouf Introduction: The lungs fall in the irradiation field for several thoracic cancer therapies. Radiation induced lung injury can cause acute radiation pneumonitis in the early phases of treatment and radiation-induced pulmonary fibrosis during later phases. Damage to normal lung tissue plays a large role in dose limitation for…
