To Move or Not to Move: When and How Bacteria Suppress Flagellar Motility

open access: yesMolecular Microbiology, EarlyView.
Motility cessation in bacteria is a key regulatory strategy that provides multiple survival advantages including enhanced community cooperation, niche adaptation and evasion of host immune responses. This process is controlled by associated mechanisms such as post‐translational modifications and second messenger signalling that stabilise non‐motile ...

Understanding exosomes in regenerative dentistry

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Regenerative dentistry is shifting from cell‐based strategies to cell‐free biologics capable of orchestrating intricate tissue repair. Exosomes, nanosized extracellular vesicles carrying bioactive molecular payloads, have emerged as central modulators of intercellular communication.

Computational modelling of cardiac fibroblast signalling reveals a key role for Ca2+ in driving atrial fibrillation‐associated fibrosis

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A pre‐existing fibroblast signalling model was enhanced by integrating atrial‐specific components and reactions linked to atrial fibrosis and atrial fibrillation (AF). The analysis highlights the central role of Ca2⁺ signalling in driving profibrotic responses to AF‐relevant stimuli, angiotensin‐II and transforming growth factor ...

Human‐derived cardiac‐neural microtissues reveal catecholaminergic polymorphic ventricular tachycardia is also a disease of the sympathetic neuron

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic diagram illustrating the proposed pathway in which regulatory defects might occur in sympathetic neurons derived from hiPSC in catecholaminergic polymorphic ventricular tachycardia (CPVT). Specifically, enhanced calcium transients appeared to derive from three sources: enhanced membrane excitability (due to loss of ...

An age‐associated decline in the role of the sarcoplasmic reticulum and associated calcium‐handling proteins sets the pace for sinoatrial node function

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Stable, responsive pacemaking in the sinoatrial node is driven by the activity of the funny current (membrane clock), interplay of calcium cycling and release from the sarcoendoplasmic reticulum with depolarising sodium‐calcium exchange current (calcium clock). With increasing age, key proteins associated with calcium cycling are

Differential Impact of Pharmacokinetic and Pharmacodynamic Variability on Response to Combination Therapy

open access: yesPharmacology Research &Perspectives, Volume 14, Issue 4, August 2026.
ABSTRACT Interindividual variability (IIV) in drug response complicates both fixed‐dose design and individualized therapy. Understanding how pharmacokinetic (PK) and pharmacodynamic (PD) processes jointly shape this variability is essential, particularly in combination therapy, where multiple interacting pathways influence outcomes. This study employed

Chiral (Stereoselective) Drugs, Asymmetric Synthesis, and Racemic Resolution Methods

open access: yesChirality, Volume 38, Issue 7, July 2026.
Chirality is crucial in drug development since both biological targets in the organism and the majority of pharmaceutical compounds are chiral. The synthesis and resolution of chiral compounds are critical steps while developing chiral drugs. Asymmetric synthesis and racemic resolution are the two most common methods for obtaining enantiopure drugs ...

Multi‐Targeting Ligands as Prospective Therapeutics for Alzheimer's Disease, a Prevalent Neurodegenerative Disorder: Mechanistic Insights, Emerging Targets and Drug Discovery Campaigns

open access: yesMedicinal Research Reviews, Volume 46, Issue 4, Page 1173-1229, July 2026.
ABSTRACT Alzheimer's disease (AD) is a debilitating neurodegenerative condition characterized by progressive cognitive impairment, memory deterioration, and neuronal dysfunction. Its complex pathophysiology involves multiple interlinked processes, including amyloid‐β (Aβ) aggregation, tau hyperphosphorylation, oxidative stress, neuroinflammation ...

Fecal Proteomics Suggest Potential Biomarkers for Non‐Alcoholic Fatty Liver Disease and Steatohepatitis

open access: yesPROTEOMICS – Clinical Applications, Volume 20, Issue 4, July 2026.
ABSTRACT Background and aims Non‐alcoholic Fatty Liver Disease (NAFLD) affects about a quarter of the world's population. Liver biopsy remains the gold standard for diagnosing the progressive form of NAFLD called Non‐alcoholic Steatohepatitis (NASH) but it is invasive, prone to sampling errors and observer variability, and impractical for widespread ...
