This protocol uses G6PI mixed peptides to construct rheumatoid arthritis models that are closer to that of human rheumatoid arthritis in CD4+ T cells and cytokines. High purity invariant natural killer T cells (mainly iNKT2) with specific phenotypes and functions were obtained by in vivo induction and in vitro purification for adoptive immunotherapy.

Multiple cell types in the retina, including endothelial cells, neurons, and glial cells, express glucose transporters (GLUTs) to enable glucose uptake into cells. Using ex vivo mouse neural retina and the fluorescent glucose analog 6-NBDG, we describe a relatively quick and inexpensive method to measure glucose uptake in the whole mouse retina.

FAQs
Its position early in carbohydrate metabolism allows cells to allocate incoming glucose among several competing needs rather than committing it to one outcome immediately. The intermediate can support ATP-generating carbohydrate breakdown, biosynthetic reactions, antioxidant-related metabolism through the pentose phosphate pathway, or storage as glycogen. This branching makes its abundance informative about cellular energy demands and metabolic priorities.
Hexokinase and glucokinase catalyze the ATP-dependent step that forms glucose 6-phosphate, so their activity influences how strongly cells channel glucose into downstream metabolism. Examining these enzymes alongside the intermediate helps researchers distinguish altered glucose entry into metabolism from changes occurring later in glycolysis, biosynthesis, or storage. This relationship is relevant to investigations of glucose homeostasis and diabetes.
When cellular conditions require stronger oxidative-stress defenses, glucose 6-phosphate can be directed into the pentose phosphate pathway rather than used exclusively for energy production or storage. Measuring the intermediate together with pathway-regulating enzymes therefore helps researchers evaluate how carbohydrate metabolism is connected to antioxidant capacity. This approach is particularly informative when studying cellular adaptation or metabolic changes associated with disease.
The destination reflects the cell’s immediate balance between energy production, biosynthetic demand, oxidative-stress defense, and glucose storage. A greater need for ATP may favor carbohydrate breakdown, whereas biosynthesis or protection from oxidative stress can increase use of other routes. Comparing glucose 6-phosphate levels with relevant enzyme measurements helps reveal how cells redistribute carbon among these pathways.
Researchers assess glucose 6-phosphate by measuring the intermediate itself and, when needed, the enzymes that regulate its formation. Interpreting both measurements provides more context than either value alone because concentration can reflect changes in glucose phosphorylation or downstream pathway use. Such analyses help characterize metabolic flux, glucose homeostasis, and altered cellular metabolism in experimental biology.
Analysis is useful when researchers need to connect glucose handling with broader cellular metabolism. Studies of diabetes can examine glucose homeostasis, while investigations of inherited metabolic disorders can identify disrupted pathway regulation. Cancer metabolism research can assess altered nutrient use, and cellular-adaptation studies can relate intermediate levels and enzyme activity to changing energy or oxidative-stress conditions.
