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.

A Potent, Selective, Small-Molecule Inhibitor of DHX9 Abrogates Proliferation of Microsatellite Instable Cancers with Deficient Mismatch Repair.

DHX9 is a multifunctional DExH-box RNA helicase with important roles in the regulation of transcription, translation, and maintenance of genome stability. Elevated expression of DHX9 is evident in multiple cancer types, including colorectal cancer (CRC). Microsatellite instable-high (MSI-H) tumors with deficient mismatch repair (dMMR) display a strong dependence on DHX9, making this helicase an attractive target for oncology drug discovery.

Increased threat learning after social isolation in human adolescents.

In animal models, social isolation impacts threat responding and threat learning, especially during development. This study examined the effects of acute social isolation on threat learning in human adolescents using an experimental, within-participant design. Participants aged 16-19 years underwent a session of complete isolation and a separate session of isolation with virtual social interactions, counterbalanced between participants, as well as a baseline session.

Investigation of the mental health and cognitive correlates of psychological decentering in adolescence.

The ability to notice and reflect on distressing internal experiences from an objective perspective, often called psychological decentering, has been posited to be protective against mental health difficulties. However, little is known about how this skill relates to age across adolescence, its relationship with mental health, and how it may impact key domains such as affective executive control and social cognition. This study analysed a pre-existing dataset including mental health measures and cognitive tasks, administered to adolescents in Greater London and Cambridge (mean age (SD) = 14.

Affective control in adolescence: The influence of age and depressive symptomatology on working memory.

People exhibit marked individual variation in their ability to exercise cognitive control in affectively charged situations. Affective control is typically assessed in laboratory settings by comparing performance in carefully constructed executive tasks performed in both affectively neutral and affectively charged contexts. There is some evidence that affective control undergoes significant improvement throughout adolescence, though it is unclear how adolescents deemed at risk of developing depression exercise affective control despite poor affective control being identified as a contributing factor to ongoing mental ill health in adulthood.
