Development and characterization of a cell donor registry for virus-specific T cell manufacture in a blood bank.

Adoptive cell therapy using virus-specific T cells (VST) is a strategy for treating common opportunistic viral infections after transplantation, particularly when these infections do not resolve through antiviral drug therapy. The availability of third-party healthy donors allows for the immediate use of cells for allogeneic therapy in cases where patients lack an appropriate donor. Here, we present the creation of a cell donor registry of human leukocyte antigen (HLA)-typed blood donors, REDOCEL, a strategic initiative to ensure the availability of compatible cells for donation when needed.

Connectivity in transfusion medicine: Challenges, benefits, and goals.

Transfusion medicine requires meticulous record keeping from the time a blood donation is made to the time a patient receives a transfusion. As such, blood collection establishments and processing laboratories generate large amounts of data. This data must be managed, analyzed, and visualized appropriately to ensure safety of the blood supply.

Human Anelloviruses: Influence of Demographic Factors, Recombination, and Worldwide Diversity.

Anelloviruses represent the major and most diverse component of the healthy human virome, referred to as the anellome. In this study, we determined the anellome of 50 blood donors, forming two sex- and age-matched groups. Anelloviruses were detected in 86% of the donors.

Pathogen inactivation methods to prevent transfusion-transmissible arboviruses: A systematic review and meta-analysis.

Objective: Arboviruses are emerging as a relevant threat to transfusion safety. Pathogen inactivation methods (PIMs) may reduce the risk of transmission through transfusion, as long as they meet minimum standards for effectiveness. This study aims to assess the log reduction of viral load achieved with different PIMs, according to the blood product they are used on and the arbovirus targeted.

Exploring the Diversity of the Human Blood Virome.

Metagenomics is greatly improving our ability to discover new viruses, as well as their possible associations with disease. However, metagenomics has also changed our understanding of viruses in general. The vast expansion of currently known viral diversity has revealed a large fraction of non-pathogenic viruses, and offers a new perspective in which viruses function as important components of many ecosystems.
