During mitosis, numerous proteins accumulate around the mitotic spindle to help it assemble and segregate sister chromatids correctly. Schweizer et al. reveal that a membranous spindle envelope facilitates the accumulation of these proteins by excluding large organelles from the spindle region. This biosights episode presents the paper by Schweizer et al. from the August 31st, 2015, issue of The Journal of Cell Biology and includes an interview with the paper's senior author, Helder Maiato...

Epithelial cells bordering a wound respond by forming two types of actin-based structure: dynamic membrane protrusions that help the cells crawl into the wound and/or seal it and an actomyosin cable that encircles the wound and closes it like a purse string. Matsubayashi et al. reveal that the endocytic remodeling of intercellular adherens junctions promotes Drosophila epidermal wound healing by coordinating the activity of multiple actin regulators at the wound edge.

Centrosomes undergo dramatic changes in size and structure during the rapid cell cycles of early Drosophila embryos. Lerit et al. reveal that a scaffold formed by the proteins centrosomin and PLP is required to maintain the activity of interphase centrosomes, which is essential for nuclear spacing and proper chromosome segregation. This biosights episode presents the paper by Lerit et al. from the July 6th, 2015, issue of The Journal of Cell Biology and includes an interview with two of the...

Aim: To evaluate whether the presence of apical periodontitis (AP), root canal treatment (RCT) and endodontic burden (EB) – as the sum of AP and RCT sites – were associated with long-term risk of incident cardiovascular events (CVE), including cardiovascular-related mortality, using data on participants in the Baltimore Longitudinal Study of Ageing (BLSA). Methodology: This retrospective cohort included 278 dentate participants in the BLSA with complete medical and dental examinations....

The BLOC-2 complex contains three subunits encoded by genes mutated in Hermansky-Pudlak syndrome, a disease caused by defects in the trafficking pathways that form melanosomes and other lysosome-related organelles. Dennis et al. reveal that the BLOC-2 complex promotes the delivery of melanosomal cargo by targeting recycling endosomal tubules to maturing melanosomes. This biosights episode presents the paper by Dennis et al. from the May 25, 2015, issue of The Journal of Cell Biology and...
