Mammalian epididymal epithelial cells are crucial for sperm maturation. Historically,
vacuole-like ultrastructures in epididymal epithelial cells were
observed via transmission electron microscopy but were undefined. Here, we
utilize volume electron microscopy (vEM) to generate 3D reconstructions of
epididymal epithelial cells and identify these vacuoles as intercellular organelle
reservoirs (IORs) in the lateral intercellular space (LIS), which contains
pr... Read more

Structure of the Ty3/Gypsy retrotransposon capsid and the evolution of retroviruses
Retroviruses evolved from long terminal repeat (LTR) retrotransposons by acquisition of envelope functions, and subsequently reinvaded host genomes. Together, endogenous retroviruses and LTR retrotransposons represent major components of animal, plant, and fungal genomes. Sequences from these elements have been exapted to perform essential host functions, including placental development, synaptic communication, and transcriptional regulation. They encode a Gag polypeptide, the capsid domains ... Read more

HIV-1 maturation occurs via multiple proteolytic cleavages of the Gag polyprotein, causing rearrangement of the virus particle required for infectivity. (…) How individual cleavages contribute to changes in protein structure and interactions, and how the mature, conical capsid forms, are poorly understood. Here, we employed cryoelectron tomography to determine morphology and high-resolution CA lattice structures for HIV1 derivatives in which Gag cleavage sites are mutated. These analyse... Read more

STIM1 promotes migration, phagosomal maturation and antigen cross-presentation in dendritic cells
Antigen cross-presentation by dendritic cells (DC) stimulates cytotoxic T cell activation to promote immunity to intracellular pathogens, viruses and cancer. Phagocytosed antigens generate potent T cell responses, but the signalling and trafficking pathways regulating their cross-presentation are unclear. Here, we show that ablation of the store-operated-Ca2+-entry regulator STIM1 in mouse myeloid cells impairs cross-presentation and DC migration in vivo and in vitro. Stim1... Read more
