Comparative single-cell and spatial transcriptomics illuminate bat immunity and barrier tissue evolution

Project description:Bats have adapted to pathogens through diverse mechanisms, including increased resistance - rapid pathogen elimination, and tolerance - limiting tissue damage following infection. In the Egyptian fruit bat (an important model in comparative immunology) several mechanisms conferring disease tolerance were discovered, but mechanisms underpinning resistance remain poorly understood. Previous studies on other species suggested that elevated basal expression of innate immune genes may lead to increased resistance to infection. Here, we test whether such transcriptional patterns occur in Egyptian fruit bat tissues through single-cell and spatial transcriptomics of gut, lung and blood cells, comparing gene expression between bat, mouse and human. Despite numerous recent loss and expansion events of interferons in the bat genome, interferon expression and induction are remarkably similar to that of mouse. In contrast, central complement system genes are highly and uniquely expressed in key regions in bat lung and gut epithelium, unlike in human and mouse. These genes also evolve rapidly in their coding sequence across the bat lineage. Finally, the bat complement system displays strong hemolytic and inhibitory activities. Together, these results indicate a distinctive transcriptional divergence of the complement system, which may be linked to bat resistance, and highlight the intricate evolutionary landscape of bat immunity.

Repurposing Large-Format Microarrays for Scalable Spatial Transcriptomics

Project description:Purpose: Here, we describe a method, Array-seq, to repurpose classical oligonucleotide microarrays for spatial transcriptomics profiling. We demonstrate that Array-seq yields spatial transcriptomes with high detection sensitivity and localization specificity using histological sections from mouse tissues as test systems. Moreover, we show that the large surface area of Array-seq slides enables the generation of spatial transcriptomes at high throughput by profiling multi-organ sections, in three dimensions by processing serial sections from one sample, and across whole human organs using spleen sections. Experimental Methods: To generate Array-seq slides, we first obtain microarrays carrying custom-design probes that contain common sequences flanking unique barcodes at known coordinates. Second, we perform a simple, two-step reaction that produces mRNA capture probes across all spots on the microarray and thereby creates Array-seq slides set for spatial transcriptomics. Following in-situ mRNA capture, reverse transcription, libaray preparation, Array-seq libraries are sequenced using the Illumina sequencing-by-synthesis (SBS) platform.

Photo-isolation chemistry for high-resolution and deep spatial transcriptome with tissue sections

Project description:We established a high-depth spatial transcriptomics technology, photo-isolation chemistry (PIC; Honda, et al., Nat Commun, 2021), which is able to isolate gene expression profiles only from photo-irradiated region out of whole tissues. In the original protocol, only the fresh-frozen sections were available, but we have now optimized it applicable to formalin-fixed frozen and formalin-fixed paraffin sections. Here, we provide an updated protocol of PIC.
