For instance, seven lncRNAs (RP11-324I22.2 (IBD), RP5-1011O1.2 (CeD), AC074391.1 (IBD), AC012370.2 (IBD), ALG9-IT1 (PsCh), BSN-AS1 (IBD, PsCh), CTC-349C3.1 (UC)) were only expressed in four T-helper cell subtypes (ThP, Th0, Th1 and Th2), whereas one lncRNA (CTD-2113 L7.1 (PBC)) was expressed in all the T cells investigated. Here, ALG9 is linked to inflammatory bowel disease.
