Summary: The basis of third harmonic generation microscopy and its versatile applications in cell and tissue research are reviewed, as well as its emerging applicability in clinical practice.

Summary: Computational modelling, or ‘microscopy’, has emerged as a powerful tool to study cell membranes across a broad range of resolutions, complementing experimental microscopy methods.


Summary: This study reveals a new function of Sp5 in mouse embryonic stem cell (ESC) self-renewal mediated by CHIR99021 and LIF, and reprogramming of EpiSCs into naїve ESCs.


Highlighted Article: This study shows new roles for the protein tyrosine phosphatase PTP-PEST in controlling EphA3 receptor tyrosine kinase activity, trafficking and Eph-induced cell retraction.

Summary: ENaCs endogenous to human endothelial cells are mechano-sensitive. Persistent activation of ENaCs will inevitably lead to endothelium dysfunction and even vascular diseases.

Highlighted Article: This study identifies the formins FHOD1 and INF2 as new components of podosomes in primary human macrophages, which regulate inter- and intra-structural contractility at discrete podosome substructures.

Summary: Reactive oxygen species cause two opposite and transient Tyr23-based modifications of annexin A2; its dephosphorylation in the nucleus and phosphorylation at the cell cortex, resulting in release of the protein in exosomes.

Highlighted Article: A combination of a Rab7 sensor and confocal FRET imaging techniques revealed that the Mon1–Ccz1 complex activates Rab7 only on late endosome and dissociates from lysosome in mammalian cells.

Summary: PGL-1 and PGL-3, members of a family of constitutive germ-granule components, suppress excessive germline apoptosis by repressing both the protein levels of CED-4 and the cytoplasmic translocation of SIR-2.1 in C. elegans.

Summary: FGF signaling modulates zygotic E-cadherin distribution to maintain posterior midgut epithelial 3D architecture, impacting on primordial germ cell motility during Drosophila early embryonic development.

Summary: Srv2/CAP is required for efficient endocytosis owing to its role in the formation of the actin patches that aid in vesicle invagination and in the formation of the actin cables that these move along.

Summary: PAK6 targeting to cell–cell contacts is dependent on both a polybasic motif and binding to Cdc42. Disruption of PAK6 targeting to cell–cell contacts inhibits epithelial cell colony escape.

Summary: CULD, a CUB- and LDLa-domain transmembrane protein that is enriched in photoreceptor cells, is required in endocytic turnover of rhodopsin and TRPL.

Summary: Down-modulation of the expression of haemoglobin-degrading falcipains in P. falciparum renders early ring stage parasites resistant to artemisinins.

Summary: Human Orc5 associates with H3 histone acetyl transferase GCN5, enhancing the chromatin-opening function of Orc5 during G1 and allows the establishment of preRCs at the origins.

Summary: Live-imaging genetic screens revealed that Rop, a homolog of the syntaxin-interacting protein Sec1/Munc18, is required for maintaining contractile ring integrity and cell shape during furrow ingression.


Highlighted Article: We provide here a novel correlative workflow combining intravital microscopy, microCT and 3D electron microscopy to reveal metastatic events in mouse brain and skin tissue at high resolution.
