Genome-wide association studies (GWAS) have identified multiple loci associated with complex diseases, but these are mostly on regulatory genes in the non-coding part of the genome and it has proved difficult to identify the effector genes that they control. Now, researchers in the U.K. have shown how single cell sequencing at scale can be used to precisely link non-coding GWAS loci to specific protein coding genes and cell types.

The microbiome and a frontline innate antimicrobial sensor, Toll-like receptor 5 (TLR5), play an essential role in the development of idiopathic pulmonary fibrosis (IPF). A scientific collaboration led by researchers at the National Institute of Environmental Health Sciences has revealed how TLR5 protects against fibrosis through its ability to modulate the lung microbiome. Their study also shows that activating TLR5 protects against fibrosis and corrects pulmonary dysbiosis.
