Autophagy is a housekeeping process to remove damaged cytoplasmic constituents. However, a debate persists on whether autophagy is beneficial or detrimental when an ischemic/reperfusion (I/R) insult occurs in the heart. This study tested the effects of autophagy enhancers (e.g. rapamycin and trehalose) and autophagy inhibitor (e.g. 3-methyladenine) on heart function and infarct size after global I (30 minutes) and R (45 minutes) when given prior to ischemia (pre-treatment) or at the beginning of reperfusion (post-treatment). We found that Rapamycin (25nM) pre-treatment and post-treatment significantly restored final left ventricular developed pressure (LVDP) to 75.4±9.1% and 60±5% of initial baseline respectively (both …

Background:This study investigates the potential role of herpes simplex virus type 1 (HSV-1) in the pathogenesis of neurodegenerative disorders, such as Alzheimer’s disease (AD), by exploring changes in gene expression related to antiviral immunity and the autophagic pathway. Autophagy is a process that recycles organelles and proteins to create more energy for the cell. This pathway has been linked to neurodegeneration, as malfunctions in the completion of this process lead to a decline in overall cellular health and function. Interestingly, HSV-1 has been shown to block the completion of autophagy, which would potentially contribute to the cytopathic changes observed …
