Target-decoy competition has been commonly used for over a decade to control the false discovery rate when analyzing tandem mass spectrometry (MS/MS) data. We recently developed a framework that uses multiple decoys to increase the number of detected peptides in MS/MS data. Here, we present a pipeline of Apache licensed, open-source software that allows the user to readily take advantage of our framework.

The first step in bottom-up proteomics is the assignment of measured fragmentation mass spectra to peptide sequences, also known as peptide spectrum matches. In recent years novel algorithms have pushed the assignment to new heights; unfortunately, different algorithms come with different strengths and weaknesses and choosing the appropriate algorithm poses a challenge for the user. Here we introduce PeptideForest, a semisupervised machine learning approach that integrates the assignments of multiple algorithms to train a random forest classifier to alleviate that issue.

Corneal neovascularization (CorNV) develops under various pathological conditions and is one of the main causes of blindness. Due to that CorNV progression involves multiple steps, anti-vascular endothelial growth factor (VEGF) drugs alone could not sufficiently suppress this process, highlighting an urgent need for an efficient delivery system for the multi-step management of CorNV. In this study, a neutrophil nanovesicle-based eye drop (NCCR) is developed for CorNV therapy that simultaneously inhibits angiogenesis and inflammation, while eliminating pathological cells through chemoexcited photodynamic therapy (PDT).

Surfactant protein-B (SP-B) deficiency is a lethal neonatal respiratory disease with few therapeutic options. Gene therapy using adeno-associated viruses (AAV) to deliver human cDNA (AAV-hSPB) can improve survival in a mouse model of SP-B deficiency. However, the effect of this gene therapy wanes.

Unlabelled: Human noroviruses (HuNoVs) are the leading cause of acute gastroenteritis worldwide. Currently, there are no targeted antivirals for the treatment of HuNoV infection. Histo-blood group antigens (HBGAs) on the intestinal epithelium are cellular attachment factors for HuNoVs; molecules that block the binding of HuNoVs to HBGAs thus have the potential to be developed as antivirals.

ModeHunter is a modular Python software package for the simulation of 3D biophysical motion across spatial resolution scales using modal analysis of elastic networks. It has been curated from our in-house Python scripts over the last 15 years, with a focus on detecting similarities of elastic motion between atomic structures, coarse-grained graphs, and volumetric data obtained from biophysical or biomedical imaging origins, such as electron microscopy or tomography. With ModeHunter, normal modes of biophysical motion can be analyzed with various static visualization techniques or brought to life by dynamics animation in terms of single or multimode trajectories or decoy ensembles.
