IgA is produced in large quantities at mucosal surfaces by IgA+ plasma cells (PC), protecting the host from pathogens, and restricting commensal access to the subepithelium. It is becoming increasingly appreciated that IgA+ PC are not constrained to mucosal barrier sites. Rather, IgA+ PC may ...
Upon reaching a recipient cell, exosomes can be internalized via endocytosis, direct fusion with the plasma membrane, or interaction with cell-surface receptors, triggering intracellular signaling pathways [15]. Endocytosis, where cells engulf extracellular material via the plasma membrane, is the ...
This insight is useful for improved risk management in the case of unwanted health effects but also for developing novel medical therapies. The concepts that help us better understand particles’ and fibres’ risks include the fate of particles in the body; exposure, dosimetry and dose-metrics ...
