Article Abstract
Drawing inspiration from the extracellular matrix (ECM), where fiber organization profoundly influences cell behavior, electrospun scaffolds have emerged as powerful tools for modulating cellular responses in vitro. While electrospinning enables the replication of ECM architecture, selecting suitable materials is paramount for effective cell adhesion and growth. In this study, we aimed to develop cost-effective scaffolds for human adipose-derived mesenchymal stromal cells (hAD-MSCs) using gelatin methacrylate (GelMA) blended with either polycaprolactone (PCL) or poly(ethylene glycol) dimethacrylate (PEGDMA). Through comparing randomly oriented and aligned fibers, we identified fiber direction as a critical factor in determining cell behavior. Surprisingly, we found that despite material hydrophobicity, the cells aligned with the fiber direction, highlighting the dominant influence of fiber alignment on cell spreading. This research underscores the importance of material selection and fiber orientation in engineering scaffolds for directing cell behavior in tissue regeneration applications.

The human chemokine receptor 8 (CCR8) received attention as target for the treatment of various autoimmune disorders. Phenoxybenzylpiperidine analogues are known to act as CCR8 agonists, although their structure-activity relationship (SAR) has been studied to a limited extent. In this study, the SAR of phenoxybenzylpiperidinyl analogues was explored in a systematic way by fusion or insertion of various heterocyclic groups on the piperidinyl ring, yielding a set of 21 novel phenoxybenzylpiperidinyl derivatives.

Amphetamines are psychostimulants that are commonly used to treat neuropsychiatric disorders and are prone to misuse. The pathogenesis of amphetamine use disorder (AUD) is associated with dysbiosis (an imbalance in the body's microbiome) and bacterially produced short-chain fatty acids (SCFAs), which are implicated in the gut-brain axis. Amphetamine exposure in both rats and humans increases the amount of intestinal , which releases SFCAs.

This research explores the dynamical properties and solutions of actin filaments, which serve as electrical conduits for ion transport along their lengths. Utilizing the Lie symmetry approach, we identify symmetry reductions that simplify the governing equation by lowering its dimensionality. This process leads to the formulation of a second-order differential equation, which, upon applying a Galilean transformation, is further converted into a system of first-order differential equations.

Sickness-induced sleep is a behavior conserved across species that promotes recovery from illness, yet the underlying mechanisms are poorly understood. Here, we show that interleukin-6-like cytokine signaling from the gut to brain glial cells regulates sleep. Under healthy conditions, this pathway promotes wakefulness.

Morphogenetic information arises from a combination of genetically encoded cellular properties and emergent cellular behaviors. The spatio-temporal implementation of this information is critical to ensure robust, reproducible tissue shapes, yet the principles underlying its organization remain unknown. We investigated this principle using the mouse auditory epithelium, the organ of Corti (OC).
