Interferon-α promotes neo-antigen formation andpreferential HLA-B-restricted antigen presentation in pancreatic β-cells

This study shows that IFN-α increases HLA-B-restricted antigen presentation in pancreatic β-cells, potentially influencing T1D pathogenesis.

Interferons are the key cytokines acting on pancreatic islets in type 1 diabetes

This study identifies IFN and IFNγ as key cytokines affecting pancreatic beta cells in type 1 diabetes through RNA-sequencing analysis and comparison with T1D islet signatures.

Differential CpG methylation at Nnat in the early establishment of beta cell heterogeneity

This study identifies differential CpG methylation at the Nnat gene as a mechanism establishing beta cell heterogeneity during development and its potential role in diabetes.

Increased expression of viral sensor MDA5 in pancreatic islets and in hormone-negative endocrine cells in recent onset type 1 diabetic donors

This study shows increased MDA5 expression in pancreatic islets and hormone-negative endocrine cells in recent-onset T1D donors compared to non-diabetic controls.

Reduced miR-184-3p expression occurring in Type 2 diabetic pancreatic islets protects β-cells from lipotoxic and proinflammatory apoptosis via a CRTC1-dependent mechanism

The paper shows reduced miR-184-3p in T2D pancreatic islets protects β-cells from apoptosis by upregulating CRTC1, with NKX6.1 controlling miR-184-3p expression.

SARS-CoV-2 receptor Angiotensin I-Converting Enzyme type 2 (ACE2) is expressed in human pancreatic β-cells and in the human pancreas microvasculature

This study shows ACE2 is expressed in human pancreatic β-cells and microvasculature, suggesting a potential link between SARS-CoV-2 and diabetes through β-cell infection or microvasculature involvement.
