The diagnosis and management of inflammatory bowel disease relies on histological assessment, which is costly, subjective, and lacks utility for point-of-care diagnosis. Fourier-transform infra-red spectroscopy provides rapid, non-destructive, reproducible, and automatable label-free biochemical imaging of tissue for diagnostic purposes. This study characterises colitis using spectroscopy, discriminates colitis from healthy tissue, and classifies inflammation severity. Hyperspectral images were obtained from fixed intestinal sections of a murine colitis model treated with cell therapy to improve inflammation. Multivariate analyses and classification modelling were performed using supervised and unsupervised machine-learning algorithms. Quantitative analysis of severe colitis showed increased protein, collagen, and nucleic acids, but reduced glycogen when compared with normal tissue. A partial least squares discriminant analysis model, including spectra from all intestinal layers, classified normal colon and severe colitis with a sensitivity of 91.4% and a specificity of 93.3%. Colitis severity was classified by a stacked ensemble model yielding an average area under the receiver operating characteristic curve of 0.95, 0.88, 0.79, and 0.85 for controls, mild, moderate, and severe colitis, respectively. Infra-red spectroscopy can detect unique biochemical features of intestinal inflammation and accurately classify normal and inflamed tissue and quantify the severity of inflammation. This is a promising alternative to histological assessment.

Oligodendrocytes (OLs) myelinate central nervous system (CNS) axons and provide metabolic support to maintain axonal integrity. Thyroid hormone (TH) is a mitogen for oligodendroglial precursor cells (OPCs) maturation into myelinating OLs. Cellular uptake of TH is mediated by monocarboxylate transporter 8 (MCT8; encoded by slc16a2 ), and its dysfunction results in intracellular triiodothyronine (T3) deprivation, leading to hypomyelination and myelin degeneration during neuroinflammation. We showed that MCT8 expression is maintained in OPCs residing within the sub–ventricular zone (SVZ) throughout CNS development, suggesting a role during OL development. We identified MCT8 deficiency during neuroinflammatory and cuprizone demyelination models, as well as in secondary progressive multiple sclerosis (SPMS). These conditions were associated with dysregulated AKT–mTOR–PANK2 signaling and abrogated Co Enzyme A and lipid synthesis pathways in the CNS during myelin degeneration. Hence, neuroprotection during SPMS maybe achieved by overcoming MCT8 deficiencies in OLs.
