In this study, we aimed to characterize immune cells in the appendix of UC patients. Method: We performed scRNA-seq on appendix cells from UC and non-UC patients. Result: A wide variety of immune cells were found in the appendix, with a marked increase in IgG-producing Plasma blast in the appendix of UC patients. Conclusion: The appendix of patients with UC were characterized by an increased number of IgG-producing cells.2026/07/29GSE284191GSM8679619GSM8679618GSM8679615GSM8679614GSM8679617GSM8679616GSM8679611GSM8679610GSM8679599GSM8679613GSM8679612GSM8679596GSM8679598GSM8679597GSM8679608GSM8679607GSM8679609GSM8679604GSM8679603GSM8679606GSM8679605GSM8679600GSM8679622GSM8679621GSM8679602GSM8679601GSM867962028038284191Homo sapiens
