Achalasia is a rare motility disorder of the esophagus resulting from abnormal immune responses, but the immunologic mechanism is unclear. Here the authors use scRNA-seq of PBMC and esophageal lower sphincter tissue and find C1QC+ macrophages and tissue-resident memory T cells with expanded compositions and altered transcriptional profiles in achalasia.
