MHC1-TIP enables single-tube multimodal immunopeptidome profiling and uncovers intratumoral heterogeneity in antigen presentation.

Profiling antigens presented on MHC class I molecules on the cell surface is essential to identify candidate antigens for targeted and personalized immunotherapies. However, mass spectrometry-based immunopeptidomics has traditionally been limited by high input requirements, extensive sample manipulation, and expensive reagents. To overcome these challenges, we developed MHC1-TIP: a scalable, single-tube and cost-effective workflow to enable robust MHC-I ligandome recovery from cell lines, patient-derived organoids, and sub-milligram amounts of clinical tissues.

Subclonal immune evasion in non-small cell lung cancer.

Cancers rarely respond completely to immunotherapy. While tumors consist of multiple genetically distinct clones, whether this affects the potential for immune escape remains unclear due to an inability to isolate and propagate individual subclones from human cancers. Here, we leverage the multi-region TRACERx lung cancer evolution study to generate a patient-derived organoid - T cell co-culture platform that allows the functional analysis of subclonal immune escape at single clone resolution.

Development of the GreenIF: A Framework to Identify Implementation Factors for Nature-Based Interventions in Healthcare Settings.

Nature-based interventions (NBIs) in healthcare settings have the potential to enhance physical and mental wellbeing of patients, healthcare staff, and visitors but are often underutilized. Knowledge about factors influencing effective implementation of NBIs in healthcare settings is scarce. This study aimed to develop a framework for identifying implementation factors relevant to NBIs in hospitals, long-term care facilities for elderly, and rehabilitation centers.

Ribociclib-Letrozole Combination as an Alternative for Neoadjuvant Chemotherapy in Selected Postmenopausal Patients with Luminal Breast Cancer (BOOG 2017-01).

Purpose: In hormone receptor-positive, HER2-negative, early-stage breast cancer, cyclin-dependent kinase 4 and 6 inhibition combined with endocrine therapy could represent a less toxic alternative to neoadjuvant chemotherapy (CT). The NEOLBC trial studied whether neoadjuvant ribociclib plus letrozole (RL) results in a doubling of complete cell-cycle arrest (CCCA; Ki67 <1% on IHC) compared with CT in the surgical specimen in luminal breast cancer.

Patients And Methods: This randomized phase II trial tailored neoadjuvant therapy in postmenopausal patients with early, luminal, HER2-negative, stage II/III breast cancer based on the percentage of Ki67-positive cancer cells after 2 weeks of letrozole.

The VEGF decoy receptor soluble Fms-like tyrosine kinase 1 binds to macrophages.

Background: Soluble Fms-like Tyrosine kinase-1 (sFLT1) is a native inhibitor of VEGF, best known for its antiangiogenic effects in preeclampsia. sFLT1 also reduces chronic inflammation and promotes tissue repair. In experimental diabetic nephropathy, we previously found that sFLT1 ameliorates kidney fibrosis and reduces the infiltration of macrophages.
