Seven years after the launch of the Human Microbiome Project, we still lack sufficient tools to visualize the microbiome in a living host. A new study provides experimental tools to label and track live anaerobic bacteria in the microbial communities in the mouse gut and beyond.
Clusters of dermal dendritic cells and T cells are required for efficient activation of T cells in skin following hapten sensitization via a process dependent on interleukin 1α (IL-1α) and the chemokine CXCL2 produced by macrophages.
A new family of genetically encoded ratiometric calcium indicators optimized for imaging of calcium signals in vivo exhibits near-linear fluorescence dynamics while minimizing artifacts caused by movement.
