Alzheimer's disease (AD) is a common copathology in Lewy body dementia (LBD). The presence of AD is associated with a distinct clinical presentation, faster progression, and shorter survival in LBD. However, the relationship between-alpha synuclein and AD remains incompletely understood.

Cell cultures, organs-on-chip and microphysiological systems become increasingly relevant as models, , in drug development, disease modelling, toxicology or cancer research. It has been underlined repeatedly that culture conditions and metabolic cues have a strong or even essential influence on the reproducibility and validity of such experiments but are often not appropriately measured or controlled. Here we review microsensor systems for cell metabolism for the continuous measurement of culture conditions in microfluidic and lab-on-chip platforms.

A recent study in PLOS Biology on the epigenetic recombination regulator PRDM9 in salmonid fish reveals that its function has been preserved across vertebrates for hundreds of millions of years, with rapidly evolving DNA-binding domains being a defining attribute.

Intricate coupling between metabolism and protein post-translational modifications (PTMs) has emerged as a fundamental aspect of cellular regulation. Recent studies demonstrate that protein modifications can originate from diverse metabolites, and that their regulation is closely tied to the cellular metabolic state. Here we explore recently uncovered PTMs, including the concept of 'modification of a modification', as well as associated feedback and feedforward regulatory mechanisms, in which modified proteins impact not only related metabolic pathways but also other signaling cascades affecting physiology and diseases.
