Interleukin‐39 is a Prognostic Biomarker and Therapy Target for Sepsis

open access: yesAdvanced Science, EarlyView.
Sepsis triggers a significant increase in IL‐39 production, with circulating levels markedly elevated and positively correlated with disease severity and poor clinical prognosis in sepsis patients. Mechanistically, macrophage‐derived IL‐39 activates the GP130 signaling pathway via a ligand‐receptor interaction, thereby fueling the pro‐inflammatory ...

Innovative Approach Reveals How Receptors Control G Protein State Equilibria

open access: yesAdvanced Science, EarlyView.
Using conformational specific trFRET biosensors of the Gi protein (depicted at the bottom), the authors show that receptor activation can not only release GDP from the inactive G protein, but can also release GTP from the activated G protein, leading to the reformation of the RG ternary complex.

Comparative Evaluation of Chelator‐Conjugated Peptides for Lead‐Labeled SSTR2‐Targeted Theranostics: Integrated Computational Modeling and Preclinical Validation

open access: yesAdvanced Science, EarlyView.
The study integrates density functional theory with radiochemical and biological validation to compare DOTA‐, PSC‐, and DOTAM‐based chelator‐conjugates for 203Pb/212Pb theranostic applications. Distinct differences in metal coordination, electrostatic properties, conformational flexibility, cellular uptake, biodistribution, and dosimetry are identified

The Role of Glutamatergic and Dopaminergic Genes in Resistant Schizophrenia: A Systematic Review

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Psychosis is a heterogeneous disorder, with approximately one‐third of patients experiencing treatment resistance, predominantly among individuals diagnosed with Schizophrenia. Treatment‐resistant schizophrenia (TRS) may stem from a distinct biological signature, involving abnormalities in the dopaminergic and glutamatergic systems.

The integrated Lei‐CNS PBPK‐PD model effectively predicts clozapine brain disposition and D2 receptor occupancy in humans

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aim Clozapine, used for treatment‐resistant schizophrenia, has a narrow therapeutic window and highly variable plasma pharmacokinetics (PK), necessitating careful monitoring. Direct measurement of unbound brain PK in humans is unethical. To develop a physiologically based pharmacokinetic–pharmacodynamic (PBPK‐PD) model to predict clozapine brain ...
