PXD026819 - lgG4 lesion of EoE patient biopsy by AutoSTOMP

Dataset Information

LgG4 lesion of EoE patient biopsy by AutoSTOMP

ABSTRACT: To test the ability of the Automated Spatially Targeted Optical Micro Proteomics (AutoSTOMP) protocol for clinical research. We collected from a patient diagnosed with active EoE (≥15 eosinophils/hpf), according to consensus guidelines, using standard endoscopy procedures, then we try to selectively obtain the proteome from the discrete lgG4+ lesions of the biopsy sections by AutoSTOMP, and try to link the lesion structure with its specially skewed constituents comparing to the rest of the tissue.

Tissue microenvironment properties like blood flow, extracellular matrix, or proximity to immune-infiltrate are important regulators of cell biology. However, methods to study regional protein expression in the native tissue environment are limited. To address this need, we developed a novel approach to visualize, purify, and measure proteins <i>in situ</i> using automated spatially targeted optical microproteomics (AutoSTOMP). Here, we report custom codes to specify regions of heterogeneity in ...[more]
