People with Long COVID Have Distinct Hormonal and Immune Differences From Those Without This Condition

Research conducted at Mount Sinai and Yale confirms long COVID is a biological disease by showing blood biomarkers that can predict who has it

Why Do Some Long Covid Patients Continue to Have Difficulty Exercising?

In a study published in the Journal of Infectious Diseases, a team of researchers from UC San Francisco found that lower than expected exercise capacity was common among people with Long COVID and chronotropic incompetence (inadequate heart rate increase during exercise) was the most common reason. They also found reduced exercise capacity to be correlated with early post-Covid elevations of inflammatory biomarkers. In addition, they found that reactivation of Epstein-Barr virus (EBV) may be related to reduced heart rate while exercising.

Monitoring Epstein-Barr viral load after liver transplant may reduce risk for rare posttransplant complication

A study of adult recipients of liver transplants has found that monitoring transplant recipients for Epstein-Barr virus viral load (EBV VL) helped to reduce risk for posttransplant lymphoproliferative disease (PTLD), a rare but serious potential complication of transplantation. The findings are published in Annals of Internal Medicine.

Wistar Scientists Make Pivotal Discovery on the Mechanism of Epstein-Barr Virus Latent Infection

Wistar researchers have discovered a new enzymatic function of the Epstein-Barr Virus (EBV) protein EBNA1, a critical factor in EBV’s ability to transform human cells and cause cancer. Published in Cell, this study provides new indications for inhibiting EBNA1 function, opening up fresh avenues for development of therapies to treat EBV-associated cancers.
