Predicting Immunotherapy Outcomes in NSCLC Using RNA and Pathology from Multicenter Clinical Trials

Advanced Science, EarlyView.
LIRA, a machine learning‐based model, is developed using transcriptomic data from 891 NSCLC patients in the OAK and POPLAR cohorts. Its predictive performance is validated in multiple external cohorts. Patients stratified by LIRA‐score exhibit distinct clinical characteristics and tumor microenvironment profiles.

A Replicable and Generalizable Neuroimaging‐Based Indicator of Pain Sensitivity Across Individuals

Advanced Science, EarlyView.
Humans differ in their sensitivity to pain. With six large and diverse fMRI datasets (total N = 1046), this study finds that such individual differences in pain sensitivity can be tracked by fMRI responses to painful stimuli. A highly generalizable machine learning model is further built to predict pain sensitivity across all datasets and analgesic ...

Mesenchymal Stromal Cells Play an Analgesic Role Through a Npy2r Sensory Neuron‐Mediated Lung‐to‐Brain Axis

Advanced Science, EarlyView.
Mesenchymal stromal cells (MSC) are considered a promising alternative for neuropathic pain (NP) treatment, but underlying mechanisms remain elusive. Huang et al. illustrate that a Npy2r sensory neuron‐related lung–brain axis contributes to MSC analgesia.

Targeted Delivery of CNS‐Specific Hesperidin as a Leptin Sensitizer for Treating Obesity‐Associated Sleep‐Disordered Breathing

Advanced Science, EarlyView.
Hesperidin nanoparticles (HE NPs) effectively combat obesity and sleep‐disordered breathing in mice by enhancing leptin sensitivity. Through suppression of hypothalamic endoplasmic reticulum stress and restoration of leptin signaling, HE NPs promote weight loss and improve breathing during sleep.
