Metabolism is highly coordinated component of the cellular activity that involves sequential chemical transformations, within a so-called metabolic network. Through these coordinated actions, living organisms acquire energy and biosynthetic precursors to maintain cellular homeostasis and function. Metabolism relies on the breaking down of macromolecules to produce energy [catabolism] and/or intermediary metabolites that are then used to construct essential building blocks for macromolecule production [anabolism]. Overall, these metabolic processes are controlled by cellular energy status: when the energy released from catabolic processes exceeds the cellular demands the storage of metabolites in the form of lipids and glycogen takes place. These phenomena have been vastly associated with the genesis of metabolic disorders, such as obesity. In recent years, we have assisted to a rediscovery of metabolism through the identification of metabolic intermediaries that act as key players on differentiation, proliferation, and function of immune cells. This recent acknowledgement of the impact of metabolism in the overall immune response originated the ground-breaking field of immunometabolism. Here, we will provide a holistic view of metabolism highlighting the biochemical principles underlying its regulation.

Circulating tumor cells (CTCs) carry intact tumor molecular information, making them invaluable for personalized cancer monitoring. However, conventional capture methods, relying on passive diffusion, suffer from low efficiency due to insufficient collision frequency, severely limiting clinical utility. Herein, a magnetic micromotor-functionalized DNA-array hunter (MMDA hunter) is developed by integrating enzyme-propelled micromotors, magnetic nanoparticles, and nucleic acid aptamers into distinct functional partitions of a DNA tile self-assembly structure.

Heart failure (HF) is a multifactorial and pathophysiological complex syndrome, involving not only neurohormonal activation but also oxidative stress, chronic low-grade inflammation, and metabolic derangements. Central to the cellular defence against oxidative damage is nuclear factor erythroid 2-related factor 2 (Nrf2), a transcription factor that orchestrates antioxidant and cytoprotective responses. Preclinical in vitro and in vivo studies reveal that Nrf2 signalling is consistently impaired in HF, contributing to the progression of myocardial dysfunction.

Super-resolution microscopy (SRM) has revolutionized fluorescence imaging enabling insights into the molecular organization of cells that were previously unconceivable. Latest developments now allow the visualization of individual molecules with nanometer precision and imaging with molecular resolution. However, translating these achievements to imaging under physiological conditions in cells remains challenging.

Purpose Of Review: This review explores the evolving understanding of efferocytosis - the clearance of dead or dying cells by phagocytes - in the context of atherosclerosis. It highlights recent discovers in cell death modalities, impaired clearance mechanisms and emerging therapeutic strategies aimed at restoring efferocytosis to stabilize plaques and resolve inflammation.
Recent Findings: Recent studies have expanded the scope of efferocytosis beyond apoptotic cells to include other pro-inflammatory cell death modes, including pyroptosis, necroptosis and ferroptosis, revealing context-dependent clearance efficiency and immunological outcomes.

Achieving a crack-free, high-surface-area photoanode is essential for maximizing the efficiency of dye-sensitized solar cells (DSSCs). In this work, rutile titanium dioxide (rTiO) nanoflowers were synthesized hydrothermally and then conformally coated with copper(I) oxide (CuO) by RF magnetron sputtering to seal pre-existing cracks and to create a nanothorn surface favorable for dye adsorption. Systematic control of the sputtering time identified 60 min as optimal condition, yielding a photoanode thickness of about 6.
