Complex sphingolipid profiling and identification of an inositol-phosphorylceramide synthase in .

is a professional phagocyte frequently used to study cellular processes underlying the recognition, engulfment, and infection course of microbial pathogens. Sphingolipids are abundant components of the plasma membrane that bind cholesterol, control membrane properties, participate in signal transmission, and serve as adhesion molecules in recognition processes relevant to immunity and infection. By combining lipidomics with a bioinformatics-based cloning strategy, we show here that produces phosphoinositol-containing sphingolipids with predominantly phytoceramide backbones.

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.

Fungal hyphae colonization by relies on biofilm matrix components.

Bacteria interact with their environment including microbes and higher eukaryotes. The ability of bacteria and fungi to affect each other are defined by various chemical, physical and biological factors. During physical association, bacterial cells can directly attach and settle on the hyphae of various fungal species.
