- A specific gene-microbe interaction drives the development of Crohn’s disease–like colitis in mice
Combined deficiency of NOD2 and NAPDH oxidase triggers Crohn’s-like disease driven by a mouse pathobiont, Mucispirillum.
- Prolonged evolution of the memory B cell response induced by a replicating adenovirus-influenza H5 vaccine
Ad4-H5 vaccine induces prolonged increases in H5-specific B cell frequency, antibody affinity, and somatic hypermutation.
- AIRE expression controls the peripheral selection of autoreactive B cells
T cells and their proper AIRE-dependent selection prevent the accumulation of autoreactive naïve B cells in the periphery.
- Modulation of asymmetric cell division as a mechanism to boost CD8+ T cell memory
CD8+ T cell memory potential can be improved by enforcement of asymmetric cell division.
- How C-terminal additions to insulin B-chain fragments create superagonists for T cells in mouse and human type 1 diabetes
In type 1 diabetes, mouse and human CD4+ T cells recognize mutated and chimeric superagonist insulin B-chain epitopes similarly.

About The Cover
ONLINE COVER Superagonist Autoantigen. Featured on the cover is a computer-generated illustration of a 3D protein structure showing the α and β chains of a human T cell receptor (TCR) recognizing a high-affinity ligand formed by binding of a modified insulin B-chain peptide to the major histocompatibility complex (MHC) class II antigen HLA-DQ8. Wang et al. used x-ray crystallography to study human and mouse TCR recognition of variant forms of an insulin B-chain peptide. C-terminal modifications of this peptide yield peptide-MHC complexes that are potent ligands for autoreactive diabetogenic T cells. These studies provide fresh insights into the structural features of the peptide ligands that spark early steps in human type 1 diabetes. [CREDIT: JOHN KAPPLER]
