CD8+ T cell function may predict type 1 diabetes progression

In this episode, Alice Long and colleagues demonstrate a link between disease outcome in type 1 diabetes and the phenotype and function of autoreactive CD8⁺ T cells.

Fibronectin variant mediates smooth muscle cell phenotypic switching

In this episode, Anil Chauhan, Manish Jain, and colleagues reveal that smooth muscle cell- specific fibronectin containing an extra domain A mediates phenotypic switching and neointimal hyperplasia.

Characterization of FOXN1 mutation-mediated immune deficiency

In this episode, Nicolai van Oers and colleagues demonstrate that compound heterozygous mutations in FOXN1 result in a combined immunodeficiency in patients that is distinct Nude/SCID phenotypes.

Breast milk-derived alkylglycerols support beige adipose tissue

In this episode, Tamás Röszer and colleagues demonstrate that breast-milk-derived alkylglycerols preserve beige adipocytes to protect against obesity.

Secondary insult reveals etiology of GATA2 enhancer mutation-associated blood disorder

The transcription factor GATA-2 is critical regulator of hematopoietic stem and progenitor cell (HSPC) development and function, and mutations in the enhancer region of GATA2 are linked to blood disorders. In this episode, Emery Bresnick and colleagues develop and characterize a mouse model that harbors a human disease-associated GATA2 enhancer mutation. In this model, hematopoietic development and function were normal unless the animals were exposed to a secondary stress that necessitated blood cell regeneration. The results of this study provide important insight into GATA-2-dependent pathogenesis.
