MAFB is essential for the maintenance of adult human α-cell identity and glucagon secretion

Katie Colbert Coate, Jinhua Liu, Min Guo, Xin Tong, Vy M. N. Coykendall, Cristina Harmelink, Nandita Dey, Garrett Reynolds, Neha Mohanty, Regina Jenkins, Radhika Aramandla, Jeeyeon Cha, Alvin C. Powers, Patrick E. MacDonald, Seung K. Kim, Roland W. Stein

This study shows that MAFB is essential for maintaining adult human α-cell identity and function, linking its downregulation to impaired glucagon secretion and mitochondrial dysfunction in diabetes.

Interruption of glucagon signaling augments islet non-alpha cell proliferation in SLC7A2- and mTOR-dependent manners

Katie Colbert Coate, Chunhua Dai, A. K. Singh, Jade E. Stanley, Brittney A. Covington, Amber M. Bradley, Favour O. Oladipupo, Yulong Gong, Scott Wisniewski, Katelyn Sellick, Erick Spears, Greg Poffenberger, Anna Marie R Schornack, Alexandria Bustabad, Tyler J. Rodgers, , E. Danielle Dean

This study shows that blocking glucagon signaling increases non-alpha cell proliferation in islets, dependent on SLC7A2 and mTORC1, across multiple species and models.
