The largest and most comprehensive cell map of the human lung is announced in Natural medicine today (June 8). By revealing the great diversity of cell types in the lung and the key differences between health and disease, the Human Lung Cell Atlas will be a valuable resource for lung researchers.
By combining data from nearly 40 studies, the researchers created the first integrated single-cell atlas of the lung, revealing rare cell types and highlighting cellular differences between healthy people. In addition, the study found common cell states between pulmonary fibrosis, cancer, and COVID-19, offering new ways to understand lung disease, which could help identify new therapeutic targets.
The study is part of the global Human Cell Atlas* (HCA) initiative to map every type of cell in the human body, to transform our understanding of health, infection and disease.
Lung research has benefited greatly from recent single cell studies showing which genes are active in each cell. Despite this, research has so far been limited by the number of samples and individuals included per study. To better understand healthy lungs and determine what is going wrong in disease, a comprehensive atlas was needed, however this has been difficult to achieve.
Now, a large team of researchers have successfully combined 49 lung data sets, from nearly 40 separate studies, into a single integrated Atlas, using advanced machine learning. By pooling and integrating data sets from all the major single-cell RNA sequencing lung studies published to date, the team created the first integrated atlas of human lung cells. This Atlas covers more than 2.4 million cells from 486 individuals and provides new insights into lung biology not previously possible.
Dr. Malte Luecken, lead author of the paper and group leader at the Institute for Computational Biology and Institute for Lung Health and Immunity in Helmholtz Munich, Germany, said: “A comprehensive organ atlas requires many data sets to capture the diversity between both cells and individuals, but combining different data sets is a great challenge We developed a benchmarking pipeline to find the optimal method to integrate all data sets into the Atlas, using artificial intelligence, and successfully combined the knowledge and data from nearly 40 previous lung studies.
Professor Fabian Theis, lead author of the paper and director of the Helmholtz Institute for Computational Biology in Munich, said: “We have created a first reference atlas of the human lung, which includes data from more than a hundred healthy people and reveals how the cells of the lungs “Individuals vary with age, sex, and smoking history. The large number of cells and individuals involved now gives the power to see rare cell types and identify new cellular states that have not been previously described.”
While the core of the Human Lung Cell Atlas is data from healthy lungs, the team also took data sets from more than 10 different lung diseases and projected them onto the healthy data to understand disease states.
The team found that different lung diseases shared common immune cell states, including the finding that a subset of macrophages (a type of immune cell) shared similar gene activity in pulmonary fibrosis, cancer, and COVID-19. The shared states indicate that these cells might play a similar role in lung scarring in all three diseases and provide pointers for potential therapeutic targets.
Professor Martijn Nawijn, lead author of the paper and professor at the University Medical Center Groningen, The Netherlands, said: “This is the first effort to compare healthy and diseased lungs in a study in an integrated manner. Our study not only supports the presence of pulmonary fibrosis in COVID-19, allows us to identify and define a shared cellular state between patients with pulmonary fibrosis, COVID-19, and lung cancer.Finding these disease-associated shared cells is really exciting and reveals a totally different way of analyzing diseases pulmonary diseases, opening possibilities for new treatment targets and developing biomarkers of treatment response. Our findings also suggest that therapies that work for one disease may help alleviate others.”
The Lung Atlas Integration project was an international collaborative effort with nearly 100 partners from more than 60 departments, including key researchers from Helmholtz Munich, University Medical Center Groningen, and Northwestern University. The team is part of the Human Cell Atlas Lung Biological Network**, which traces its roots to the Chan Zuckerberg Initiative Seed Networks for the Human Cell Atlas, and the EU-funded DiscovAIR lung network. At the start of the COVID-19 pandemic in 2020, single cell lung communities quickly came together and formed the HCA Lung Biological Network to help understand COVID-19, which then led to the global effort to integrate all the data.
Lisa Sikkema, first author of the paper and a PhD student at the Helmholtz Institute for Computational Biology Munich, said: “One of the big problems in creating the integrated lung cell atlas was cell type annotation. Different research groups used different names for the same cell type, or the same name for different cells, so as a team we worked to standardize them using the data from the atlas.The atlas is a first step toward a consensus annotation of the human lung, which will help bring together the field of lung research”.
The Human Lung Cell Atlas, the first major body integrated within the Human Cell Atlas initiative, is publicly available to researchers around the world, as a central resource for studying the lung in health and disease.
Dr. Alexander Misharin, lead author of the paper and associate professor at Northwestern University Feinberg School of Medicine, USA, can be mapped onto the HLCA, transforming research in lung biology and disease As the first comprehensive reference atlas of a As a major organ, the HLCA also represents a milestone toward achieving a comprehensive Human Cell Atlas that will transform our understanding of biology and disease and the foundation for a new era of healthcare.”
