Overview of Gene Research
Ildr2, also known as angulin-3, is a member of the Ig superfamily and is implicated in tricellular tight junctions. It has a role in pancreatic islet health, immune regulation, and hepatic lipid homeostasis. In pancreatic β -cells, it may be involved in a new pathway related to hypoinsulinemic hyperglycemia [1]. In the immune system, it can deliver inhibitory signals to T cells, and ILDR2-Fc shows potential in treating autoimmune diseases by regulating immune homeostasis and inducing antigen-specific immune tolerance [3,4].
In gene-knockout studies, liver-specific Ildr2 knockout mice did not develop hepatic steatosis, indicating that previous observations of hepatic steatosis in Ildr2 knockdown mice were likely due to "off-target" effects of shRNA [2]. In Ildr2-knockout mice related to glomerulopathies, there was glomerular hypertrophy and decreased podocyte density, suggesting a protective role of ILDR2 in glomerulopathies [5].
In conclusion, Ildr2 is crucial in multiple biological processes such as pancreatic function, immune regulation, and lipid and glomerular homeostasis. Gene-knockout mouse models have been instrumental in clarifying its role in hepatic steatosis and glomerulopathies, providing insights into potential therapeutic targets for related diseases.
