Subunit protein CD40.SARS.CoV2 vaccine induces SARS-CoV-2-specific stem cell-like memory CD8 T cells.

Background: Ideally, vaccination should induce protective long-lived humoral and cellular immunity. Current licensed COVID-19 mRNA vaccines focused on the spike (S) region induce neutralizing antibodies that rapidly wane.

Methods: Herein, we show that a subunit vaccine (CD40.

Macrophages are activated toward phagocytic lymphoma cell clearance by pentose phosphate pathway inhibition.

Macrophages in the B cell lymphoma microenvironment represent a functional node in progression and therapeutic response. We assessed metabolic regulation of macrophages in the context of therapeutic antibody-mediated phagocytosis. Pentose phosphate pathway (PPP) inhibition induces increased phagocytic lymphoma cell clearance by macrophages in vitro, in primary human chronic lymphocytic leukemia (CLL) patient co-cultures, and in mouse models.

Transcatheter Edge-to-Edge Repair for Severe Isolated Tricuspid Regurgitation: The Tri.Fr Randomized Clinical Trial.

Importance: Correction of tricuspid regurgitation using tricuspid transcatheter edge-to-edge repair (T-TEER) in addition to guideline-directed optimized medical therapy (OMT) may improve clinical outcomes.

Objective: To evaluate the efficacy of T-TEER + OMT vs OMT alone in patients with severe, symptomatic tricuspid regurgitation.

Design, Setting, And Participants: Investigator-initiated, prospective, randomized (1:1) trial evaluating T-TEER + OMT vs OMT alone in adult patients with severe, symptomatic tricuspid regurgitation.

Insights from Ecstatic Epilepsy: From Uncertainty to Metacognitive Feelings.

Ecstatic epilepsy is a rare form of focal epilepsy linked to the anterior insula in which patients experience a blissful state with a unique set of symptoms, including a feeling of physical well-being, mental clarity, a sense of oneness with the universe, and time dilation. In this chapter, we reflect on how these symptoms coincide with our current knowledge of the insula's functions and explore how this stunning natural model can further inform our understanding of the insula's role in the sentient self, uncertainty and surprise monitoring, and metacognitive feelings.
