Summary: The electrical regulation of plasmonic Au nanodisk (AuND) arrays integrated with conductive polymers (PPy, PANI, and PEDOT) is systematically investigated in this work. By altering the complex dielectric function of the polymer coatings based on electrically controlled redox reaction, the reflection spectrum and structural color of the hybrid AuND arrays are dynamically modulated. Different polymers exhibit distinct refractive index responses to external voltage, resulting in different spectral variations, response time, and cycle stability for the polymer-coated AuND arrays.

Summary: Electrohydrodynamic (EHD) printing is used to fabricate microfibrous architectures for cellular orientation, but orderly deposition of microfibers with cell-scale spacing is challenging. A finite element method is established to analyze the electrostatic forces induced on the EHD-printed microfibers, and it is found that uniform fiber arrangement can be achieved when the fiber spacing is five times larger than the fiber diameter. Decreasing the fiber spacing improves neurite outgrowth length and Schwann cell migration.

Summary: This study highlights the molecular changes in cell-cell adhesion caused by POMGNT1 deficiency, revealing an increased abundance of N-cadherin and site-specific changes in N-glycan structures. Furthermore, POMGNT1-deficient cells activate ERK1/2 and p38 signaling pathways and trigger transcriptional changes comparable to epithelial-mesenchymal transition (EMT), suggesting a potential molecular mechanism underlying the observed phenotype. The impact of changes in O-mannosylation on N-glycosylation may contribute to the complex clinical symptoms of MEB or alpha-dystroglycanopathy.

Summary: Embryonic Dissociated Dorsal Root Ganglia (DRG) cultures are commonly used to study the role of novel molecular pathways or drugs in Schwann cell development and myelination. This study found that the transition from SCP to iSC occurs between the 5th and 7th day in culture, and immature Schwann cells can differentiate into myelinating Schwann cells as early as 4 days post the induction of myelination in cocultures. Furthermore, coculture-derived Schwann cell monocultures exhibit similar myelinating potential to cultures established from neonatal sciatic nerves, providing valuable insight for future studies on Schwann cell development and myelination.

Summary: This study introduces an approach inspired by biological tissues, where azide-modified living cells are covalently cross-linked with alkyne-modified alginate polymers via bioorthogonal reactions to create self-healing hydrogels. The unique self-healing capabilities of these hydrogels come from cadherin-mediated adhesion between cells within the gel. This research showcases the incorporation of living components into synthetic materials to enhance self-healing properties.

Summary: This study focused on electrically controlled transdermal drug delivery using pectin/bacteria cellulose hydrogel composites. The research showed that drug release was optimized at 30 wt% bacteria cellulose content, and could be increased to 78% under applied electrical potential. The hydrogel composites also exhibited remarkable antibacterial activity, making them valuable alternative materials for transdermal drug delivery.

Summary: Paclitaxel-induced peripheral neuropathy (PIPN) is a neurological disorder caused by paclitaxel (PTX) treatment in cancer patients. Schwann cell-derived exosomes (SC-EXOs) have been found to effectively improve PIPN both in vitro and in vivo. SC-EXOs alleviate PTX-induced mechanical nociceptive sensitization, ameliorate nerve fiber loss and DRG injury, and protect damaged neurons by upregulating miR-21 to repress the PTEN signaling pathway. These findings provide a novel strategy for the treatment of PIPN.

Summary: This study transformed industrial lignin into a lignin-based polyporous carbon@polypyrrole (LPC@PPy) using a hydrothermal-activation-in situ polymerization strategy for removal of reactive blue 19. The adsorption capacity of LPC@PPy for reactive blue 19 is significantly higher compared to LPC and LC, due to the even distribution of oxygen and nitrogen groups in the 3D pore structure. LPC@PPy maintained a high adsorption capacity even after 8 cycles and N and O groups, such as pyridinic-N, C-OH, -COOR, -C-O-, and C--C, played important roles in the adsorption process.

Summary: The chronic reliability of bioelectronic neural interfaces has been challenged by foreign body reactions, but engineered microtopographies, such as Sharklet (TM), have shown potential in manipulating cellular responses to the implanted device. While surface patterning is a strong physical tool for modulating cell behavior, responses to micropatterns are highly dependent on the cell type, with Schwann cells found to be more metabolically active and aligned than fibroblasts when compared between the same pattern.

Summary: Microphysiological systems (MPS) incorporating 3D skeletal myobundles are used to study new medical treatments for sarcopenia. In this study, myobundles derived from young, active individuals showed better response to electrical stimulation and increased hypertrophic potential compared to myobundles derived from older sedentary individuals. This research provides a disease model and experimental platform for studying the effects of electrical stimulation on muscle aging and evaluating the efficacy and toxicity of new drugs for sarcopenia.
