Innate Immune Activation Is a Strong Suppressor of CCL22 and Impedes Regulatory T Cell–Dendritic Cell Interaction

Immunology, EarlyView.
During homeostasis, CCL22 is secreted by dendritic cells (DC), which mediate contacts between regulatory T cells (Treg) and DC to maintain immune balance. Activation of innate immunity via microbes or pattern recognition receptor (PRR) agonists induces the secretion of several soluble factors (e.g., type I and II interferons, IL‐10), which mediate ...

Pathogen‐reduced platelet concentrates in France: Impact on the risk of transfusion‐transmitted infections, 2017–2024

Vox Sanguinis, EarlyView.
Abstract Background and Objectives Pathogen reduction (PR) using amotosalen‐UVA was implemented for 100% of platelet concentrates (PCs) in France in November 2017. No bacterial testing was in place earlier. The impact of PR on the risk of transfusion‐transmitted infections (TTIs) from November 2017 to December 2022 (vs.

Neurologic abnormalities in HTLV-I– and HTLV-II–infected individuals without overt myelopathy [PDF]

Neurology, 2009
Human T-lymphotropic virus (HTLV) type I is the causative agent of HTLV-associated myelopathy (HAM)/tropical spastic paraparesis, and a number of HAM cases with HTLV-II infection have also been reported. However, despite some reports, it is unclear whether HTLV-I or -II infection is associated with other neurologic manifestations.An analysis of medical
