Postinfusion PD-1+ CD8+ CAR T cells identify patients responsive to CD19 CAR T-cell therapy in non-Hodgkin lymphoma.

Chimeric antigen receptor (CAR) T-cell therapy has revolutionized treatment for relapsed/refractory B-cell non-Hodgkin lymphoma (NHL). Robust biomarkers and a complete understanding of CAR T-cell function in the postinfusion phase remain limited. Here, we used a 37-color spectral flow cytometry panel to perform high dimensional single-cell analysis of postinfusion samples in 26 patients treated with CD28 costimulatory domain containing commercial CAR T cells for NHL and focused on computationally gated CD8+ CAR T cells.

Development and consensus of entrustable professional activities for final-year medical students in anaesthesiology.

Background: The transfer of classic concepts of competency-based medical education into clinical practice has been proven to be difficult in the past, being described as partially fragmented, misleading and inadequate. At the beginning of training, novice doctors commonly feel overwhelmed, overloaded and exposed to extreme time pressure. The discrepancy between expected and actual clinical competence of doctors at the start of their speciality training jeopardizes patient safety.

Quorum Sensing and Cyclic di-GMP Exert Control Over Motility of KB2B1.

Bacterial motility is critical for symbiotic colonization by of its host, the squid , facilitating movement from surface biofilms to spaces deep inside the symbiotic organ. While colonization has been studied traditionally using strain ES114, others, including KB2B1, can outcompete ES114 for colonization for a variety of reasons, including superior biofilm formation. We report here that KB2B1 also exhibits an unusual pattern of migration through a soft agar medium: whereas ES114 migrates rapidly and steadily, KB2B1 migrates slowly and then ceases migration.
