Innate Immune Reprogramming Mediated by Endogenous Retroelement Dysregulation Drives Multiple Sclerosis Progression

Annals of Clinical and Translational Neurology, EarlyView.
Epigenetic reprogramming in hematopoietic stem and progenitor cells (HSPCs) and downstream myeloid cells, mediated by H3.3 downregulation and endogenous retroelement (ERE) overexpression, contributes to the progression of multiple sclerosis (MS). ABSTRACT Background Skewed myelopoiesis in the bone marrow has been identified as a key driver of multiple ...

Long-Term Evolution

Communication Systems, 2019
The mobile communications’ standard that succeeded the UMTS system became known as Long-Term Evolution (LTE). The Long-Term Evolution–Advanced, or LTE-Advanced (LTE-A) version, was developed by the Third-Generation Partnership Project (3GPP). The LTE-A exceeds the International Telecommunication Union (ITU) requirements for the fourth-generation ...
