The vacuolar anti- activity of neutrophil primary granule peptidyl-arginine deiminase enzymes.

The role of neutrophils in host defense involves several cell processes including phagocytosis, degranulation of antimicrobial proteins, and the release of neutrophil extracellular traps (NETs). In turn, dysregulated cell activity is associated with the pathogenesis of airway and rheumatic diseases, in which neutrophil-derived enzymes including peptidyl-arginine deiminases (PADs) play a role. Known physiological functions of PADs in neutrophils are limited to the activity of PAD isotype 4 in histone citrullination in NET formation.

All hands on deck during the COVID-19 pandemic. Maintaining face-to-face medical education and clinical placements.

Medical students must have robust educational experiences, graduate and commence timely employment. Here, we describe how the Royal College of Surgeons in Ireland (RCSI) delivered clinical placements in medical programmes over the first three waves of the COVID-19 pandemic in Ireland, including a student-centred, holistic approach to students' educational, social and health needs with strong student involvement, re-organising the university's primary care team, developing COVID-19 PCR testing on site and re-focusing communications and student services. This resulted in re-arranging the students into learning communities, and students and staff electronically recorded their COVID-19 symptom status daily.
