Generation of Allogeneic CAR‐T Circumvents Functional Deficits in Patient‐Derived Autologous Product for Glioblastoma

open access: yesInternational Journal of Cancer, EarlyView.
Clinical trials of chimeric antigen receptor T‐cell (CAR‐T) therapies in glioblastoma have shown limited clinical benefits. Whether this may be explained by the basal quality of CAR‐T products, which are currently generated using patient, autologous T‐cells, has been little explored.

Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...
