Determining Effective Treatment Regimens For Breast Cancer Using Combined Immunotherapy And Chemotherapy In Vivo, Akhila Kunuthuru

AUCTUS: The Journal of Undergraduate Research and Creative Scholarship

Breast cancer has the highest incidence rate of all cancers globally in women, and those of African descent, especially West African females, face higher rates of triple-negative breast cancer (TNBC), a more aggressive form of breast cancer. Immunotherapy for breast cancer is a relatively new treatment option, and research is ongoing to identify the best combination treatments for increasing survival of those diagnosed with TNBC. Eganelisib (IPI-549: a PI3K-gamma inhibitor that works to shift M2 macrophages to M1 to augment T cell function) with other combinatory treatments has shown promising results in reducing tumor growth and increasing survival in mice. …

Infiltrating Cd8+ T Cells Exacerbate Alzheimer’S Disease Pathology In A 3d Human Neuroimmune Axis Model, Jefin Jose, Devam Purohit

VCU's Medical Journal Club: The Work of Future Health Professionals

In this study, Jorfi et al. employed a neuroimmune axis model containing neurons, astrocytes, and microglia to examine the role of immune cells in Alzheimer's disease. Jorfi et al. found that T cells selectively infiltrated the BRAIN compartment of the neuroimmune axis model as compared to B cells and monocytes. Jorfi et al. further found that CD8+ T cells demonstrated heightened cytotoxicity in the Alzheimer's disease brain, illuminating the role of immune cells in neurodegeneration. Upon further examination, the CXCR3-CXCL10 signaling pathway was found to have an important role in inflammation.

A Genome-Wide In Vivo Crispr Screen Identifies Essential Regulators Of T Cell Migration To The Cns In A Multiple Sclerosis Model, Jefin Jose

VCU's Medical Journal Club: The Work of Future Health Professionals

Kendirli et al. (2023) used a CRISPR screen to determine the proteins involved in T cell migration into the CNS in multiple sclerosis. Overall, eighteen facilitators and five brakes to T cell infiltration into the CNS were identified. Kendirli et al. specifically identified ITGA4, FERMT3, and HSP90B1 to make up the adhesion module, CXCR3, GNAI2, and TBX21 to make up the chemotaxis module, and GRK2 and S1PR2 to make up the egress module. This study demonstrated the ability of a CRISPR screen to identify elements in a disease process and thus identify targets for future multiple sclerosis therapies.

Pediatrics Publications

To identify predictors of neonatal ECMO circuit health, a retrospective analysis of circuit functional pressure and flow parameters as well as infant clotting values were collected 48 h prior to and 24 h post circuit change. Circuit impairment was defined as need for partial or total circuit change. Statistical analysis used multivariate statistics and non-parametric Mann–Whitney U-test with possible non-normality of measurements. A total of 9764 ECMO circuit and clotting values in 21 circuits were analyzed. Circuit delta-P mean, and maximum values increased from 8.62 to 48.59 mmHg (p < 0.011) and 16.00 to 53.00 mmHg (p < 0.0128) respectively prior to need for circuit change. Maximum and mean Pump Flow Revolutions per minute (RPM) increased by 75% (p < 0.0043) and 81% (p < 0.0057), respectively. Mean plasma free hemoglobin (pfHb) increased from 26.45 to 76.00 mg/dl, (p < 0.0209). Sweep, venous pressure, and clotting parameters were unaffected. ECMO circuit delta-P, RPM, and pfHb were early predictors of circuit impairment.

Cystic Fibrosis And Sleep Circadian Rhythms, Mariam Louis, Peter Staiano, Lavender Micalo, Nauman Chaudary Jan 2022

Cystic Fibrosis And Sleep Circadian Rhythms, Mariam Louis, Peter Staiano, Lavender Micalo, Nauman Chaudary

Internal Medicine Publications

Cystic fibrosis (CF) is due to a mutation in the cystic fibrosis transmembrane conductance regulator gene (CFTR), which leads to unusual water and chloride secretion across epithelial surfaces. The lungs are responsible for most morbidity, though other organs are frequently affected. Sleep abnormalities have long been recognized in CF. Abnormal ventilation and oxygenation, sinus disease, deconditioning due to muscle weakness and recurrent infections, and inflammation have been thought to play a role in sleep disorders in CF. However, there is evidence that CFTR gene dysregulation can affect circadian rhythms in CF. Early recognition and treatment of circadian rhythms may improve …

Trankle, Dinesh Kadariya, Salvatore Carbone, Georgia Thomas, Jeremy Turlington, Roshanak Markley, Justin M. Canada, Giuseppe G. Biondi‐Zoccai, Michael C. Kontos, Benjamin W. Van Tassell, Antonio Abbate

Internal Medicine Publications

Leukocytosis is a common finding in patients with ST elevation myocardial infarction (STEMI) and portends a poor prognosis. Interleukin 1-β regulates leukopoiesis and pre-clinical studies suggest that anakinra (recombinant human interleukin-1 [IL-1] receptor antagonist) suppresses leukocytosis in myocardial infarction. However, the effect of IL-1 blockade with anakinra on leukocyte count in patients with STEMI is unknown. We reviewed the white blood cell (WBC) and differential count of 99 patients enrolled in a clinical trial of anakinra (n = 64) versus placebo (n = 35) for 14 days after STEMI. A complete blood cell count with differential count were obtained at …

Gregory Hundley, Antonio Abbate

Internal Medicine Publications

Background

Radiation-induced myocardial fibrosis increases heart failure (HF) risk and is associated with a restrictive cardiomyopathy phenotype. The myocardial extracellular volume fraction (ECVF) using contrast-enhanced cardiac magnetic resonance (CMR) quantifies the extent of fibrosis which, in severe cases, results in a noncompliant left ventricle (LV) with an inability to augment exercise stroke volume (SV). The peak exercise oxygen pulse (O2Pulse), a noninvasive surrogate for exercise SV, may provide mechanistic insight into cardiac reserve. The relationship between LV ECVF and O2Pulse following thoracic radiotherapy has not been explored.

Methods

Patients who underwent thoracic radiotherapy for chest malignancies with significant incidental heart …


Calpain-Mediated Protein Targets In Cardiac Mitochondria Following Ischemia–Reperfusion, Ling Li, Jeremy Thompson, Ying Hu, Edward J. Lesnefsky, Belinda Willard, Qun Chen Jan 2022

Calpain-Mediated Protein Targets In Cardiac Mitochondria Following Ischemia–Reperfusion, Ling Li, Jeremy Thompson, Ying Hu, Edward J. Lesnefsky, Belinda Willard, Qun Chen

Internal Medicine Publications

Calpain 1 and 2 (CPN1/2) are calcium-dependent cysteine proteases that exist in cytosol and mitochondria. Pharmacologic inhibition of CPN1/2 decreases cardiac injury during ischemia (ISC)–reperfusion (REP) by improving mitochondrial function. However, the protein targets of CPN1/2 activation during ISC–REP are unclear. CPN1/2 include a large subunit and a small regulatory subunit 1 (CPNS1). Genetic deletion of CPNS1 eliminates the activities of both CPN1 and CPN2. Conditional cardiomyocyte specific CPNS1 deletion mice were used in the present study to clarify the role of CPN1/2 activation in mitochondrial damage during ISC–REP with an emphasis on identifying the potential protein targets of CPN1/2. …

Radiology Publications

Background
Although prior reports have evaluated the clinical and cost impacts of cardiovascular magnetic resonance (CMR) for low-to-intermediate-risk patients with suspected significant coronary artery disease (CAD), the cost-effectiveness of CMR compared to relevant comparators remains poorly understood. We aimed to summarize the cost-effectiveness literature on CMR for CAD and create a cost-effectiveness calculator, useable worldwide, to approximate the cost-per-quality-adjusted-life-year (QALY) of CMR and relevant comparators with context-specific patient-level and system-level inputs.

Methods
We searched the Tufts Cost-Effectiveness Analysis Registry and PubMed for cost-per-QALY or cost-per-life-year-saved studies of CMR to detect significant CAD. We also developed a linear regression meta-model (CMR …

Surgery Publications

Transforming Growth Factor β (TGFβ) is a key mediator of immune evasion in pancreatic ductal adenocarcinoma (PDAC), and the addition of TGFβ inhibitors in select immunotherapy regimens shows early promise. Though the TGFβ target SMAD4 is deleted in approximately 55% of PDAC tumors, the effects of SMAD4 loss on tumor immunity have yet to be fully explored. Using a combination of genomic databases and PDAC specimens, we found that tumors with loss of SMAD4 have a comparatively poor T-cell infiltrate. SMAD4 loss was also associated with a reduction in several chemokines with known roles in T-cell recruitment, which was recapitulated …

Repeated Exposure To Chlorpyrifos Is Associated With A Dose-Dependent Chronic Neurobehavioral Deficit In Adult Rats, Ana C. R. Ribeiro, Elisa Hawkins, Fay M. Jahr, Joseph L. Mcclay, Laxmikant Deshpande

Neurology Publications

Organophosphate (OP) chemicals include commonly used pesticides and chemical warfare agents, and mechanistically they are potent inhibitors of the cholinesterase (ChE) enzyme. Epidemiological studies report long-term neuropsychiatric issues, including depression and cognitive impairments in OP-exposed individuals. Chlorpyrifos (CPF) is one of the most widely used pesticides worldwide. Multiple laboratory studies have reported on either the long-term behavioral effect of an acute high-dose CPF (30-250 mg/kg) or studied sub-chronic behavioral effects, particularly the motor and cognitive effects of repeated low-dose CPF. However, studies are lacking on chronic mood and depression-related morbidities following repeated CPF doses that would mimic occupationally relevant OP …
