A Quality Metric for the Systematic Evaluation of Clearing Protocols
3D multicellular spheroids are of interest for studying tumor behavior and evaluating the response of pharmacologically active agents, because they mimic the in vivo tumor environment better than…Read article
New Light Shed on the Nanodomain Organization of the Endoplasmic Reticulum (ER)
The endoplasmic reticulum (ER) is a continuous membrane organelle in charge of protein synthesis, lipid synthesis and detoxification. The ER structure is described in terms of smooth peripheral…Read article
Human NK Cell Development Requires CD56-mediated Motility and Formation of the Developmental Synapse
While distinct stages of natural killer (NK) cell development have been defined, the molecular interactions that shape human NK cell maturation are poorly understood. Here we define intercellular…Read article
Actin-Dependent Vacuolar Occupancy of the Cell Determines Auxin-Induced Growth Repression
The cytoskeleton is an early attribute of cellular life, and its main components are composed of conserved proteins. The actin cytoskeleton has a direct impact on the control of cell size in animal…Read article
Variety of RNAs in Peripheral Blood Cells, Plasma, and Plasma Fractions
Human peripheral blood contains RNA in cells and in extracellular membrane vesicles, microvesicles and exosomes, as well as in cell-free ribonucleoproteins. Circulating mRNAs and noncoding RNAs, being…Read article
Super-Resolution Optical Microscopy of Lipid Plasma Membrane Dynamics
Plasma membrane dynamics are an important ruler of cellular activity, particularly through the interaction and diffusion dynamics of membrane-embedded proteins and lipids. FCS (fluorescence…Read article
Adeno-associated Viral Vectors do not Efficiently Target Muscle Satellite Cells
Adeno-associated viral (AAV) vectors are becoming an important tool for gene therapy of numerous genetic and other disorders. Several recombinant AAV vectors (rAAV) have the ability to transduce…Read article
The Actin Cytoskeleton Modulates the Activation of iNKT Cells by Segregating CD1d Nanoclusters on Antigen-Presenting Cells
The ability of invariant natural killer T (iNKT) cells to recognize endogenous antigens represents a distinct immune recognition strategy, which underscores the constitutive memory phenotype of iNKT…Read article
Highly Selective Fluorescent and Colorimetric Probe for Live-cell Monitoring of Sulphide Based on Bioorthogonal Reaction
H2S is the third endogenously generated gaseous signaling compound and has also been known to involve a variety of physiological processes. To better understand its physiological and pathological…Read article
TFG Promotes Organization of Transitional ER and Efficient Collagen Secretion
Collagen is the most abundant protein in the animal kingdom. It is of fundamental importance during development for cell differentiation and tissue morphogenesis as well as in pathological processes…Read article
The Bimodally Expressed MicroRNA miR‐142 Gates Exit from Pluripotency
A stem cell's decision to self‐renew or differentiate is thought to critically depend on signaling cues provided by its environment. It is unclear whether stem cells have the intrinsic capacity to…Read article
Cross-strand Binding of TFAM to a Single mtDNA Molecule Forms the Mitochondrial Nucleoid
Scientists from three Max Planck Institutes have gained fundamental insights into the organization of mitochondrial DNA (mtDNA). The researchers observed in high-resolution images gained with nobel…Read article
Fluorescent Proteins Illuminate Cell Biology
Green fluorescent protein (GFP) isolated from the jellyfish Aequorea victoria and GFP-like fluorescent proteins from other animals have had an important role in the technical innovations that have…Read article
Cortical Actin Networks Induce Spatio-temporal Confinement of Phospholipids in the Plasma Membrane – A Minimally Invasive Investigation by STED-FCS
Important discoveries in the last decades have changed our view of the plasma membrane organisation. Specifically, the cortical cytoskeleton has emerged as a key modulator of the lateral diffusion of…Read article
Correlating Intravital Multi-Photon Microscopy to 3D Electron Microscopy of Invading Tumor Cells Using Anatomical Reference Points
Cancer research unsing multiphoton microscopy and 3D electron microscopy. Correlative microscopy combines the advantages of both light and electron microscopy to enable imaging of rare and transient…Read article
