The HALO\u2122 platform facilitated quantitative image analysis of infiltrating T lymphocytes, macrophages, and target organ insulin and glucagon cells. Whole genome sequencing (WGS) was employed to identify candidate type 1 diabetes genes.\n\nSerum IgE levels increased with age in normoglycemic BB Gimap5-DP rats. Quantification of infiltrating cells per mm2 in and around the islets indicated that T lymphocytes are the initial infiltrators, followed by macrophages. Elevated serum IgE levels inversely correlated with beta-cell mass (total mg insulin/mg pancreas). WGS refined the risk segment for islet inflammation to 1.02 Mbp, leaving 10 candidate genes, including Gimap4 and Gimap5.\n\nElevated IgE levels herald T lymphocyte and macrophage infiltration. Pancreatic islet inflammation was linked to Gimap4, Gimap5, and other potential candidate genes on rat chromosome 4.", "doi": "10.1007/s00011-025-02101-9", "pmid": "41042382", "labels": {"Bioinformatics (NBIS)": "Collaborative", "Bioinformatics Support and Infrastructure": "Collaborative", "Bioinformatics Support, Infrastructure and Training": "Collaborative", "Bioinformatics Support for Computational Resources": "Service"}, "xrefs": [{"db": "pmc", "key": "PMC12494634"}, {"db": "pii", "key": "10.1007/s00011-025-02101-9"}], "notes": [], "created": "2025-11-17T15:46:13.623Z", "modified": "2025-11-28T10:40:57.524Z"}
