Live-cell imaging analysis provides tremendous information for the study of cellular events such as growth cone migration in neuronal development. Here, we describe a protocol for live-cell imaging of migrating PVD dendritic growth cones in the nematode by spinning-disk confocal microscopy. Fluorescently labeled growth cones and cytoskeletal proteins could be continuously observed for 4-6 h in mid-stage larvae. This protocol is suitable for revealing the dynamic molecular and cellular events in dendrite and axon development of . For complete details on the use and execution of this protocol, please refer to Chen et al. (2019).

We present novel fluorescent cholesteryl probes (CNDs) with a modular design based on the solvatochromic 1,8-phthalimide scaffold. We have explored how different modules-linkers and head groups-affect the ability of these probes to integrate into lipid membranes and how they distribute intracellularly in mouse astrocytes and fibroblasts targeting lysosomes and lipid droplets. Each compound was assessed for its solvatochromic behavior in organic solvents and model membranes.

Objective: Abnormal mechanical stress is intimately coupled with osteoarthritis (OA). Microtubules play a vital role in the regulation of mechanotransduction and intracellular transport. The purpose of the present study was to investigate the impact of stress-induced microtubule impairment on intracellular transport and lipid droplet (LD) accumulation in chondrocytes.

Transthyretin is a thyroid hormone binding protein with a major role in the distribution of thyroid hormones to peripheral tissues. In preeclampsia, the failing placenta releases soluble endoglin into the maternal circulation causing systemic vascular dysfunction. Our group has previously shown that transthyretin binds to soluble endoglin and is taken up as a complex into hepatocytes.

We present protocols for using an optogenetic tool called LILAC for actin imaging. LILAC is a light-controlled version of Lifeact that uses the Avena sativa LOV2 (AsLOV2) domain. By significantly reducing Lifeact's affinity for the cytoskeleton in the dark, LILAC reduces concentration-dependent negative side effects while enabling new image processing methods.

Purpose: Atopic dermatitis (AD) is the most common chronic inflammatory skin disease that severely impairs patient's life quality and represents significant therapeutic challenge due to its pathophysiology arising from skin barrier dysfunction. Topical corticosteroids, the mainstay treatment for mild to moderate AD, are usually formulated into conventional dosage forms that are impeded by low drug permeation, resulting in high doses with consequent adverse effects, and also lack properties that would strengthen the skin barrier. Herein, we aimed to develop biomimetic lamellar lyotropic liquid crystals (LLCs), offering a novel alternative to conventional AD treatment.
