Lymphangiogenesis via VEGF-C/VEGFR-3 Pathway Following Myocardial Ischemia-Reperfusion Injury due to Myocardial Infarction

Melanie L. Painter Introduction. Myocardial infarction results from insufficient blood flow to the heart. Endogenous lymphangiogenesis is initiated after myocardial infarction and serves a protective role against the development of heart failure by reducing inflammation and edema.3 Vascular Endothelial Growth Factor C (VEGF-C) and VEGF Receptor 3 (VEGFR-3) both increase…

Macrophage Polarization and Renal Migration in the Etiology of Hypertension

Chris Ortigoza Introduction. Heart disease is the greatest cause of death in the United States.1 Hypertension represents the most important modifiable risk factor implicated in heart disease,2 representing a major risk factor in coronary and peripheral atherosclerosis, cardiac hypertrophy3, heart failure, ischemic stroke, intracerebral hemorrhage and chronic end-stage renal disease.3…

Altered Synthesis of Hydrogen Sulfide Plays a Key Role in the Pathogenesis of Renovascular Hypertension

Clarence Lim Introduction. Renovascular hypertension is defined as a systolic blood pressure greater than 130 mmHg or a diastolic blood pressure greater than 80 mmHg with renovascular etiologies7. Renovascular hypertension accounts for approximately 3% of cases in unselected hypertensive patients7. Altered metabolism is a key cause in hypertension5,6,8,9. Studies have…

Pathogenesis of how IL-17A produced by CD4+ T helper 17 cells result in renal and vascular dysfunction and augment angiotensin II induced hypertension

Adiba Hasnat Introduction.  Angiotensin II hypertension is strongly linked to the immune system since many of the detrimental effects are caused by the inflammatory response mediated by immune cells such as Th17 cells7. Th17 have been shown to augment and not just be a secondary response to hypertension by promoting…

Myocarditis following treatment with Immune Checkpoint Inhibitors

Kenneth Ford  Introduction. Immune checkpoint inhibitors are some of the most exciting new therapies in the world of cancer treatment. These inhibitors of PD-1 and CTLA-4 have become first line therapy for metastatic melanoma, non-small cell lung cancer, and second line drugs for an increasing number of malignancies.1 Immune checkpoint…

CCR7-Mediated Chemotaxis: Expansion of the Cardiovascular Lymphatic Network via VEGF-C therapy in Atherosclerosis

Wajahat Dawood Introduction. Atherosclerosis is an accumulation of immune cells due to CCR7-mediated chemotaxis as a result of LDL buildup in the intimal layers of endothelial cells. Atherosclerosis is a major cause of cardiovascular diseases with increased risks of ischemic stroke, peripheral arterial disease, and myocardial infarctions.1,2 Researchers found the…
