Unlabelled: Coxsackievirus B3 (CVB3) is a non-enveloped picornavirus that can cause systemic inflammatory diseases including myocarditis, pericarditis, pancreatitis, and meningoencephalitis. We have previously reported that following infection, CVB3 localizes to mitochondria, inducing mitochondrial fission and mitophagy, while inhibiting lysosomal degradation by blocking autophagosome-lysosome fusion. This results in the release of virus-laden mitophagosomes from the host cell as infectious extracellular vesicles (EVs) which allow non-lytic viral egress.

Plasma membrane protein degradation and recycling are regulated by the endolysosomal system, wherein endocytic vesicles bud from the plasma membrane into the cytoplasm and mature into endosomes and then degradative lysosomes. As such, the endolysosomal system plays a critical role in determining the abundance of proteins on the cell surface and influencing cellular identity and function. Highly polarized cells, like neurons, rely on the endolysosomal system for axonal and dendritic specialization and synaptic compartmentalization.

By self-insuring, employers bear the financial risk for enrollees' health care spending and are accountable for plan management, either directly or by contracting with a third-party administrator. Using National Association of Insurance Commissioners data, we demonstrate that insurers are deeply entrenched in the provision of administrative services only (ASO) contracts for self-insured employers.
