Inflammation in Dry Eye Disease-Pathogenesis, Preclinical Animal Models, and Treatments.

J Ocul Pharmacol Ther

December 2024

Buchanan Ocular Therapeutics Unit, Department of Ophthalmology, Aotearoa-New Zealand National Eye Centre, Faculty of Medical and Health Sciences, The University of Auckland, Auckland, New Zealand.

Dry eye disease (DED) is a rapidly growing ocular surface disease with a significant socioeconomic impact that affects the patients' visual function and, thus, their quality of life. It is distinguished by a loss of tear film homeostasis, leading to tear film instability, hyperosmolarity, ocular surface inflammation, and neurosensory abnormalities, with all of these playing etiological roles in the propagation of the vicious DED circle. While current treatments primarily focus on reducing tear film instability and hyperosmolarity, increasingly more attention is being placed on tackling the underlying inflammation that propagates and potentiates these factors.

Article Synopsis
  • The study aims to understand how specific molecular changes, particularly the expression of a certain gene, influence the clinical outcomes of patients with pulmonary carcinoids, which can range from slow-growing to deadly tumors.
  • Researchers analyzed RNA sequencing data from two cohorts of pulmonary carcinoid patients (totaling 193) to determine the prognostic value of this gene expression and its relationship with telomerase activity, which is linked to tumor aggressiveness.
  • Results showed that high expression of the gene correlates with worse survival rates and is an independent predictor of poor clinical outcomes, suggesting that it could be a key factor in assessing the severity of pulmonary carcinoids.

Exp Brain Res

November 2024

Institute of Neuroscience & Medicine (INM-3), Cognitive Neuroscience, Forschungszentrum Jülich, Leo-Brandt-Str. 5, 52425, Jülich, Germany.

Efficient responses in dynamic environments rely on a combination of readiness and flexibility, regulated by anticipatory and online response control mechanisms. The latter are required when a motor response needs to be reprogrammed or when flanker stimuli induce response conflict and they are crucially modulated by anticipatory signals such as response and conflict expectations. The mutual influence and interplay of these control processes remain to be elucidated.
