The conjunctival transcriptome in scarring trachoma

ABSTRACT: Trachoma is a poorly understood immuno-fibrogenic disease process, initiated by Chlamydia trachomatis (Ct). Differences in conjunctival gene expression profiles between Ethiopians with trachomatous trichiasis (with (TTI) and without (TT) inflammation) and controls (NC) were investigated to identify relevant host responses. Tarsal conjunctival swab samples were collected for RNA isolation and Ct PCR. Transcriptome-wide microarray experiments were conducted on 42 samples (TTI 13, TT 15, NC14). Specific results were confirmed using multiplex quantitative RT-PCR for 16 mRNA targets in an independent collection of case-control samples: 386 case-control pairs (TTI 244, TT 142, NC 386). The gene expression profiles of cases were consistent with: squamous metaplasia (Keratins, SPRR), pro-inflammat
