Intrinsic pH chemosensitivity of acutely dissociated medullary serotonergic and retrotrapezoid neurones

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Central respiratory chemoreceptors (CRCs) are critical for maintaining normal systemic levels of pH and PCO2. A CRC must respond to pH via intrinsic mechanisms. Here we quantified intrinsic chemosensitivity of medullary 5‐HT neurones and retrotrapezoid nucleus (RTN) neurones using acute dissociation.

Antagonistic response regulators spatially regulate receptor methylation in the Pseudomonas aeruginosa Pil-Chp surface sensing system

open access: yesCell Reports
Summary: Most bacterial chemosensory systems encode enzymes that are predicted to methylate and demethylate their chemoreceptors to control signaling activity.

The role of group III/IV afferent feedback in the ventilatory, pressor and metabolic responses to exercise in normoxia and hypoxia

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Participants completed cycling exercise with (placebo) and without (25 µg intrathecal fentanyl) intact group III/IV muscle afferent feedback in three settings: normoxia, acute hypoxia and chronic hypoxia after 7–9 days of acclimatisation (∼3800 m). Blocking afferent feedback suppressed exercise hyperpnoea across all environments,

Intratumoral Microbiota in Tumor: Current Understandings and Future Perspectives

open access: yesMedComm, Volume 7, Issue 7, July 2026.
Intratumoral bacteria are emerging as active regulators of cancer evolution rather than bystanders. This review outlines how tumor‐resident microbes drive tumor initiation and growth by inducing genomic instability, epigenetic reprogramming, oncogenic signaling, and chronic inflammation, while promoting metastatic spread via invasion, angiogenesis ...

Effects of Oral Health and Functional Characteristics on Taste Sensitivity in Older Adults: Comparative Analysis Using Solution and Taste Strip Tests

open access: yesJournal of Oral Rehabilitation, Volume 53, Issue 7, Page 1286-1295, July 2026.
Oral and functional status differentially modify gustatory assessment in older adults. Salivary and swallowing functions selectively affect strip and solution tests, respectively, highlighting the complementary roles of these methods for comprehensive evaluation and personalised management of taste dysfunction.

Single-array measurements reveal non-uniform, mosaic-like chemosensory arrays in bacteria

open access: yesNature Communications
Motile bacteria use supramolecular arrays to detect effector gradients in their environment. In Escherichia coli, thousands of chemoreceptor molecules with diverse sensory properties cooperatively modulate the kinase activity of these arrays and, via ...

Bioprinted Tumor Microenvironment Models Reveal Immune Evasion and Guide CAR‐NK Therapeutic Strategies

open access: yesAdvanced Science, Volume 13, Issue 36, 29 June 2026.
This study presents a 3D embedded bioprinting platform that recapitulates key stromal features of the tumor microenvironment using fibroblasts and lung‐derived ECM. The model enables functional assessment of CAR‐NK cells and provides a versatile tool to support the development of next‐generation immunotherapeutic strategies against solid tumors ...

The formation of polar chemoreceptor clusters is altered in the absence of RecA protein.

open access: yes, 2014
A) A representative fluorescence microscopy image of the ΔcheR ΔrecA strain harboring plasmid pUA1127, containing the inducible eYFP::cheR fusion. Images of the ΔcheR and ΔcheRΔcheW strains containing the gene fusion were also included as positive and ...

Reproxalap ‐ A Novel Treatment Option for Allergic Conjunctivitis – A Comprehensive Narrative Review

open access: yesHealth Science Reports, Volume 9, Issue 6, June 2026.
ABSTRACT Background and Aims Allergic conjunctivitis is a prevalent, immune‐mediated hypersensitivity disorder of the ocular surface affecting 10%–20% of the global population. Current therapeutic options, while effective to some extent, are often limited by side effects and inconsistent efficacy.
