IHC for human GLP1R expression. Pancreata from wild-type (+/+) and B-hGLP1R mice (H/H) were stained using an antibody specific for human GLP1R. and only the pancreas from B-hGLP1R mice (H/H) showed hGLP1R positive signal in plasma membrane.

Human GLP1R expression in different tissues of B-hGLP1R mice by IHC. Tissues were stained with human-specific antibodies GLP1R (B-L). The spleen of wild-type C57BL/6JNifdc mice was tissue-negative control (A). The Pancreas of C57BL/6JNifdc mice shows human GLP1R negative (B). The islet of the pancreas, striatum septum of brain, gastric mucosal layer and myenteric plexus of stomach, partial blood vessels the kidney, the muscularis propria nerve plexus of both large intestine and small intestine, and the interstitial cells of the small intestine mucosal layer of B-hGLP1R mice show human GLP1R positive (C, D, F, G, K, L). Lung, liver, adipose, and skeletal muscle of B-hGLP1R mice show human GLP1R negative. Original magnification ×200. Abbreviations: IHC, immunohistochemistry.

Study of Orforglipron in B-hGLP1R mice food intake. B-hGLP1R mice (9-week-old) were acclimated for QD PO dosing with vehicle for 4 days, and mice were grouped by body weight and daily food intake. All animals will be placed in clean cages and fasted overnight, mice will be dosed with vehicle or test compound in the morning (before 10AM). All group's food will be added 15 minutes post dosing, and food remaining will be recorded at 2-,4-,6-,8-, 24-, 32-, and 48h post dosing. Values are expressed as mean ± SEM.

Analysis of spleen leukocyte subpopulations by FACS. Splenocytes were isolated from female C57BL/6 and B-hGLP1R mice (n=3, 9-week-old). Flow cytometry analysis of the splenocytes were performed to assess leukocyte subpopulations. A. Representative FACS plots. Single live cells were gated for the CD45+ population and used for further analysis as indicated here. B. Results of FACS analysis. Percent of T cells, B cells, NK cells, monocytes, dendritic cells, granulocytes and macrophages in homozygous B-hGLP1R mice were similar to those in the C57BL/6 mice, demonstrating that GLP1R humanized does not change the overall development, differentiation or distribution of these cell types in spleen. Values are expressed as mean ± SEM.

Analysis of T cell subpopulation in spleen, blood and lymph node. The lymphocytes were isolated from spleen, lymph node and blood in C57BL/6 and B-hGLP1R mice (n=3, 9-week-old). The proportion of T cells subpopulation was tested by flow cytometry. There were no differences between C57BL/6 and B-hGLP1R mice, demonstrating that humanized of GLP1R does not change the overall development, differentiation or distribution of these T cell subtypes. Values are expressed as mean ± SEM.
