Dysregulation of Astrocytic ATP/Adenosine Release in the Hippocampus Cause Cognitive and Affective Disorders: Molecular Mechanisms, Diagnosis, and Therapy

open access: yesMedComm, Volume 6, Issue 5, May 2025.
Reactive astrocytes release various molecules, which play a role in maintaining central nervous system (CNS) homeostasis. (1) Gliotransmitters, such as glutamate, γ‐aminobutyric acid (GABA), ATP, and D‐serine, are secreted by vesicular exocytosis. In addition, astrocytes can also release ATP and glutamate through (2) P2X7Rs, (3) connexin‐43 (Cx43 ...

Spatiotemporal Control Over Circadian Rhythms With Light

open access: yesMedicinal Research Reviews, Volume 45, Issue 3, Page 968-984, May 2025.
ABSTRACT Circadian rhythms are endogenous biological oscillators that synchronize internal physiological processes and behaviors with external environmental changes, sustaining homeostasis and health. Disruption of circadian rhythms leads to numerous diseases, including cardiovascular and metabolic diseases, cancer, diabetes, and neurological disorders.

Circadian regulation of key physiological processes by the RITMO1 clock protein in the marine diatom Phaeodactylum tricornutum

open access: yesNew Phytologist, Volume 246, Issue 4, Page 1724-1739, May 2025.
Summary Phasing biological and physiological processes to periodic light–dark cycles is crucial for the life of most organisms. Marine diatoms, as many phytoplanktonic species, exhibit biological rhythms, yet their molecular timekeepers remain largely uncharacterized.

The clockwork of insect activity: Advancing ecological understanding through automation

open access: yesJournal of Animal Ecology, Volume 94, Issue 4, Page 597-610, April 2025.
The study demonstrates that time‐controlled insect sampling using an automated Malaise trap in combination with metabarcoding allows for the observation and documentation of taxon‐specific activity patterns. These recorded activity patterns can provide valuable insights into the underlying ecological processes, including parasitoid–host relationships ...
