Unlocking the molecular mechanism of pathogenic and non-pathogenic Th17 cells with InTraSeq 3241

Abstract Description Single-cell RNA sequencing (scRNA-seq) provides a partial view of cellular function. To address this, InTraSeq enables the simultaneous measurement of mRNA, surface, cytoplasmic, and nuclear proteins within individual cells. This multimodal approach offers a comprehensive view of cellular function by combining RNA and protein profiling from the same sample. InTraSeq allows researchers to expand their view of critical intracellular protein expression, including post-translational modifications (PTMs) and transcription factors. This is valuable for understanding cell population heterogeneity and identifying distinct functional states. We used InTraSeq to characterize Th17 cell differentiation, simultaneously profiling RNA and protein expression in over 85,000 cells. Our results revealed novel insights into Th17 cell differentiation, including the identification of key regulatory factors and their target genes. By simultaneously measuring mRNA, extra and intra-cellular proteins, signaling proteins, and PTMs, InTraSeq offers a comprehensive understanding of cellular processes and enables the identification of novel regulatory mechanisms.
