The results suggest that T cells and orbital fibroblasts participate in an antigen-dependent positive feedback loop in which presentation of autoantigens by fibroblasts via MHC class II and CD40-CD40L signaling results in T-cell activation. These activated T cells stimulate fibroblast proliferation, leading to fibroblast-associated diseases in GO. Thus, therapies that interfere with CD40-CD40L signaling, antigen expression by fibroblasts, or T-cell function may be effective in preventing progression of GO symptoms.

The development of efficient biomarkers and probes for monitoring and treating cancer, specifically metastatic cancer, is a critical research area that can have a significant impact on both patient outcomes and drug discovery. In this context, TiNIR has been developed to detect tumor-initiating cells (TICs), with heme oxygenase 2 (HO2) as a promising therapeutic biomarker for tumor-initiating cells. In this study, TiNIR has demonstrated its effectiveness as an in vivo metastatic lung cancer tracker, highlighting its potential as a valuable tool in cancer research and therapy. The development of innovative approaches that selectively target metastatic cancers represents a promising avenue for improving survival rates and enhancing the quality of life of cancer patients.
