Cortisol, Anxiety, and TNFα Mediate the Relationship Between BMI and Executive Functions

open access: yesStress and Health, Volume 41, Issue 4, August 2025.
ABSTRACT Overweight and obesity are associated with poorer executive functions (EF). The underlying mechanisms contributing to this relationship are not yet conclusive, but cortisol, anxiety, and inflammation are likely among the contributing factors. Our objective was to evaluate whether fibrinogen, tumour necrosis factor alpha (TNFα), cortisol, and ...

Aetiopathogenesis of infantile epileptic spasms syndrome and mechanisms of action of adrenocorticotrophin hormone/corticosteroids in children: A scoping review

open access: yesDevelopmental Medicine &Child Neurology, Volume 67, Issue 8, Page 1004-1025, August 2025.
Why does infantile epileptic spasms syndrome (IESS) occur with a variety of underlying conditions and why does it respond to adrenocorticotrophin hormone (ACTH)/corticosteroids? Our scoping review summarizes five hypotheses from the literature: gene/epigenetic regulation, stress/HPA axis activation, neuroinflammation/immune function, altered neuronal ...

Structural Basis of Regioselective Bromination of Tricyclic Tryptoline by the Tryptophan Halogenase Thal

open access: yesChemBioChem, Volume 26, Issue 13, July 11, 2025.
This study shows that the flavin‐dependent tryptophan halogenase Thal also regioselectively halogenates the tricyclic non‐native substrate tryptoline, a β‐carboline with various pharmacological activities. Interestingly, Thal brominates a different position of the shared pharmacophore indole in tryptoline than it does in tryptophan. A crystal structure

Muscle‐Derived Small Extracellular Vesicles Mediate Exercise‐Induced Cognitive Protection in Chronic Cerebral Hypoperfusion

open access: yesAdvanced Science, Volume 12, Issue 27, July 17, 2025.
sEVs have a critical role in orchestrating interorgan crosstalk and mediating exercise‐induced therapeutic effects. Lin et al. demonstrates that sEVs miR‐17/20a‐5p mediates the muscle‐brain crosstalk and emphasizes the central role of mTOR signaling in executing molecular programs that can protect brain health in response to exercise. Abstract Physical

First‐in‐human phase 1 study of KHK2455 monotherapy and in combination with mogamulizumab in patients with advanced solid tumors

open access: yesCancer, Volume 131, Issue 13, 1 July 2025.
Abstract Background Indoleamine 2,3‐dioxygenase 1 (IDO1) is a heme‐containing enzyme that degrades tryptophan (Trp) to kynurenine (Kyn), which suppresses effector T cells and reduces antitumor activity. KHK2455 is a long‐acting selective IDO1 inhibitor that blocks the heme component of the IDO holoenzyme.
