Helminth extracellular vesicles co-opt host monocytes to drive T cell anergy.

Parasitic helminths secrete extracellular vesicles (EVs) into their host tissues to modulate immune responses, but the underlying mechanisms are poorly understood. We demonstrate that Ascaris EVs are efficiently internalised by monocytes in human peripheral blood mononuclear cells and increase the percentage of classical monocytes. Furthermore, EV treatment of monocytes induced a novel anti-inflammatory phenotype characterised by CD14, CD16, CC chemokine receptor 2 (CCR2) and programmed death-ligand 1 (PD-L1) cells.

Psychological interventions in the Italian national health system: appropriateness and accountability.

In the field of clinical governance, the search for progressive high-quality health interventions is accompanied by the different health values they assume for the different stakeholders involved. With increasing frequency, the value of clinical psychology and psychotherapy interventions in the public service is also supported by their ability to be appropriate and measurable in terms of their effectiveness. As such, their expected future is one of systematic inclusion within increasingly defined and specific care pathways.

Do You Want to Stay Single? Considerations on Single-Arm Trials in Drug Development and the Postregulatory Space.

Single-arm trials (SATs), while not preferred, remain in use throughout the drug development cycle. They may be accepted by regulators in particular contexts (e.g.

A pulsar in a binary with a compact object in the mass gap between neutron stars and black holes.

Some compact objects observed in gravitational wave events have masses in the gap between known neutron stars (NSs) and black holes (BHs). The nature of these mass gap objects is unknown, as is the formation of their host binary systems. We report pulsar timing observations made with the Karoo Array Telescope (MeerKAT) of PSR J0514-4002E, an eccentric binary millisecond pulsar in the globular cluster NGC 1851.
