The identification of tumor-specific antigens (TSAs) is critical for developing effective cancer immunotherapies. Mass spectrometry (MS)-based immunopeptidomics has emerged as a powerful tool identifying TSAs physical molecules. However, current platforms face challenges in measuring low-abundance precise, sensitive, and reproducible manner from small needle-tissue biopsies (<1 mg). Inspired by recent advances single-cell proteomics, microfluidics technology offers promising solution to these limitations providing improved isolation human leukocyte antigen (HLA)-associated peptides with higher sensitivity. In this context, we highlight the sample preparation rationale immunopeptidomics. Additionally, provide an overview microfluidic methods, including microchip pillar arrays, valved-based systems, droplet microfluidics, digital discuss latest research on their application MS-based proteomics.

Efficacy of cancer immunotherapies relies on correct recognition tumor antigens by lymphocytes, eliciting thus functional responses capable eliminating cells. Therefore, important efforts have been carried out in antigen identification, with the aim understanding mechanisms response to immunotherapy and design safer more efficient strategies. In addition classical tumor-associated identified during last decades, implementation next-generation sequencing methodologies is enabling identification neoantigens (neoAgs) arising from mutations, leading development new neoAg-directed therapies. Moreover, there are numerous non-classical originated other sources methodologies. Here, we review relevance neoAgs different results obtained applying neoAg-based addition, types best approaches for their described. This will help increase spectrum targetable molecules useful immunotherapies.

Abstract RNA velocity exploits the temporal information contained in spliced and unspliced counts to infer transcriptional dynamics. Existing models often rely on coarse biophysical simplifications or numerical approximations solve underlying ordinary differential equations (ODEs), which can compromise accuracy challenging settings, such as complex weak transcription rate changes across cellular trajectories. Here we present cell2fate, a formulation of based linearization ODE, allows solving biophysically more accurate model fully Bayesian fashion. As result, cell2fate decomposes solutions into modules, providing connection between statistical dimensionality reduction. We comprehensively benchmark real-world demonstrating enhanced interpretability power reconstruct dynamics dynamical signals rare mature cell types. Finally, apply developing human brain, where spatially map modules onto tissue architecture, connecting spatial organization tissues with transcription.
