Deletion of CD226 in Foxp3+ T cells Reduces Diabetes Incidence in Non-Obese Diabetic Mice by Improving Regulatory T Cell Stability and Function

P. Thirawatananond, M. Brown, L. Sachs, J. Arnoletti, W.-I. Yeh, A. L. Posgai, M. Shapiro, Y.-G. Chen, T. Brusko

This study shows that deleting CD226 in regulatory T cells reduces diabetes in NOD mice by enhancing Treg stability and function.

Insulin-like Growth Factor-1 Synergizes with IL-2 to Induce Homeostatic Proliferation of Regulatory T cells

M. R. Shapiro, L. D. Peters, M. E. Brown, C. Cabello-Kindelan, A. L. Posgai, A. L. Bayer, T. M. Brusko

This study shows that IGF1 and IL-2 together expand regulatory T cells more effectively than either alone, through distinct signaling pathways and receptor expression changes.

ACE2 and SARS-CoV-2 Expression in the Normal and COVID-19 Pancreas

I. Kusmartseva, W. Wu, F. Syed, V. van der Heide, M. Jorgensen, P. Joseph, X. Tang, E. Candelario-Jalil, C. Yang, H. Nick, J. Harbert, A. L. Posgai, R. Lloyd, S. Cechin, A. Pugliese, , M. A. Atkinson

This study examines ACE2 and SARS-CoV-2 expression in normal and COVID-19 pancreas tissues, finding prominent ACE2 expression in ductal epithelium and microvasculature, with limited endocrine cell expression and no strong evidence of SARS-CoV-2 infection of endocrine cells.
