Lymphangioleiomyomatosis (LAM) Cell Atlas

Area of Science:

• Pulmonology
• Genomics
• Bioinformatics

Background:

• Lymphangioleiomyomatosis (LAM) is a rare, progressive lung disease primarily affecting women, characterized by cystic lung remodeling and respiratory failure.
• The precise cellular makeup, microenvironment, and interactions within LAM lesions are not fully understood, hindering research and therapeutic development.

Purpose of the Study:

• To conduct an integrated analysis of single-cell data from LAM patients across multiple organs (lung, uterus, kidney).
• To develop a centralized, interactive resource, the LAM Cell Atlas (LCA) Web-Portal, for collaborative research.
• To enable detailed investigation of genetic dysregulation at transcriptomic, epigenomic, and cell-cell interaction levels within LAM.

Main Methods:

• Compiled and integrated single-cell multiomics data from three research centers, encompassing lung, uterus, and kidney tissues from LAM patients.
• Developed the LAM Cell Atlas (LCA) Web-Portal, offering interactive tools for data exploration and reanalysis.
• Utilized advanced bioinformatics approaches to analyze transcriptomic, epigenomic, and cell-cell connectome data.

Main Results:

• The LCA provides a comprehensive dataset for studying LAM pathogenesis at a single-cell resolution.
• Analysis revealed dysregulated genetic programs contributing to the disease.
• The portal facilitates visualization and reanalysis of complex multiomics data, enabling deeper insights into LAM biology.

Conclusions:

• The LAM Cell Atlas (LCA) is a valuable resource for advancing collaborative research into Lymphangioleiomyomatosis.
• Understanding the cellular and molecular underpinnings of LAM lesions is crucial for developing effective treatments.
• The LCA empowers researchers to explore multiomics data and uncover novel therapeutic targets for LAM.
