Analysis of tumor-infiltrating exhausted T cells highlights IL-6 and PD1 blockade as a combined immunotherapy strategy for non-small cell lung cancer.

Objective: Given the limitations of immunotherapy for treating non-small cell lung cancer (NSCLC), we investigated the phenotype and function of exhausted CD8T cells and analyzed a novel combination immunotherapy to restore the effector killing function of tumor-infiltrating CD8T lymphocyte (TIL).

Methods: We examined the expression and function of immunosuppressive molecules on CD8T cells of peripheral blood mononuclear cells (PBMCs) and TILs by using prospectively collected peripheral blood, pleural effusions, and tumor tissues from patients with NSCLC and correlated the results with clinical data. We then evaluated the effect of interleukin 6 (IL-6) stimulation on CD8T cells.

Regional changes in brain metabolism during the progression of mild cognitive impairment: a longitudinal study based on radiomics.

Background: This study aimed to establish radiomics models based on positron emission tomography (PET) images to longitudinally predict transition from mild cognitive impairment (MCI) to Alzheimer's disease (AD).

Methods: In our study, 278 MCI patients from the ADNI database were analyzed, where 60 transitioned to AD (pMCI) and 218 remained stable (sMCI) over 48 months. Patients were divided into a training set (n = 222) and a validation set (n = 56).

Differential effects of alcohols on conformational switchovers in alpha-helical and beta-sheet protein models.

Organic solvents may induce non-native structures of proteins that mimic folding intermediates and/or conformations that occur in proximity to biological membranes. Here we systematically investigate the effects of simple (i.e.

Interface mutation in heptameric co-chaperonin protein 10 destabilizes subunits but not interfaces.

We here report on a human mitochondrial co-chaperonin protein 10 (cpn10) variant in which the conserved interface residue leucine-96 is replaced with glycine (Leu96Gly cpn10). According to analytical ultracentrifugation, the mutation does not perturb the ability to assemble into a heptamer and electron microscopy reveals that Leu96Gly cpn10 is ring-shaped like wild-type cpn10. Despite elimination of a hydrophobic residue, the subunit-subunit affinity is essentially identical in Leu96Gly cpn10 and in wild-type cpn10.
