ロックフェラー大学のLeslie Vosshall研究室を中心とする国際チームは、黄熱病蚊 Aedes aegypti の全身細胞を網羅した世界初の「モスキート・セル・アトラス」を作成し、論文を Cell 誌に発表した。単一核RNAシーケンシングにより、19組織・36万7千以上の細胞核を解析し、69種類の細胞型と14分類群を特定。これまで知られていなかった多感覚ニューロンの存在や、雌雄での遺伝子発現の違い、吸血後のメス脳での劇的な遺伝子変化を明らかにした。また、脚や口器が甘味や水分を感知する能力を持つことも発見。データセットは一般公開され、感染症媒介蚊の行動・神経・生殖研究の基盤として期待されている。

Highlights

  • snRNA-seq atlas (>367,000 nuclei) from 19 male and female Aedes aegypti mosquito tissues
  • Or82 and ppk317 cells show sex-specific expression in the antenna
  • Appendage sensory neurons co-express genes from multiple chemosensory receptor families
  • Glia, not neurons, show the most dramatic transcriptional changes in the brain after blood feeding

Summary

The female Aedes aegypti mosquito’s remarkable ability to hunt humans and transmit pathogens relies on her unique biology. Here, we present the Aedes aegypti Mosquito Cell Atlas, a comprehensive single-nucleus RNA sequencing dataset of more than 367,000 nuclei from 19 dissected tissues of adult female and male Aedes aegypti, providing cellular-level resolution of mosquito biology. We identify novel cell types and expand our understanding of sensory neuron organization of chemoreceptors across all sensory tissues. Our analysis uncovers male-specific cells and sexually dimorphic gene expression in the antenna and brain. In female mosquitoes, we find that glial cells, rather than neurons, undergo the most extensive transcriptional changes in the brain following blood feeding. Our findings provide insights into the cellular basis of mosquito behavior and sexual dimorphism. The Aedes aegypti Mosquito Cell Atlas resource enables systematic investigation of cell-type-specific expression across all mosquito tissues.
