ER-dependent membrane repair of mycobacteria-induced vacuole damage.

Tuberculosis still remains a global burden and is one of the top infectious diseases from a single pathogen. , the causative agent, has perfected many ways to replicate and persist within its host. While mycobacteria induce vacuole damage to evade the toxic environment and eventually escape into the cytosol, the host recruits repair machineries to restore the MCV membrane.

Quantitative Spatio-temporal Analysis of Phagosome Maturation in Live Cells.

Phagocytosis and phagosome maturation are central processes to the development of the innate and adaptive immune response. Phagosome maturation is a continuous and dynamic process that occurs rapidly. In this chapter we describe fluorescence-based live cell imaging methods for the quantitative and temporal analysis of phagosome maturation of beads and M.

ILC1 drive intestinal epithelial and matrix remodelling.

Organoids can shed light on the dynamic interplay between complex tissues and rare cell types within a controlled microenvironment. Here, we develop gut organoid cocultures with type-1 innate lymphoid cells (ILC1) to dissect the impact of their accumulation in inflamed intestines. We demonstrate that murine and human ILC1 secrete transforming growth factor β1, driving expansion of CD44v6 epithelial crypts.
