A role for nitric oxide-driven retrograde signaling in the consolidation of a fear memory

open access: yesFrontiers in Behavioral Neuroscience, 2010
In both invertebrate and vertebrate models of synaptic plasticity, signaling via the putative “retrograde messenger” nitric oxide (NO) has been hypothesized to serve as a critical link between functional and structural alterations at pre- and

The basic chemistry of exercise-induced DNA oxidation:oxidative damage, redox signalling and their interplay [PDF]

open access: yes, 2015
Acute exercise increases reactive oxygen and nitrogen species generation. This phenomenon is associated with two major outcomes: (1) redox signalling and (2) macromolecule damage.

A Central Somatic Transmission Mediates Proprioceptive Facilitation of Muscle Pain

open access: yesAdvanced Science, EarlyView.
Zhang et al. uncover a novel central mechanism for persistent muscle pain, in which TRPA1 sensitization in MeV proprioceptive neurons enhances somatic secretion. This, in turn, disinhibits descending pain control from neighboring noradrenergic locus coeruleus neurons via local GABAergic circuits, thereby promoting inflammatory muscle pain.

Recent Advances in Understanding Carotenoid Derived Signaling Molecules in Regulating Plant Growth and Development

open access: yesFrontiers in Plant Science, 2015
Carotenoids (C40) are synthesized in plastids and perform numerous important functions in these organelles. In addition, carotenoids can be processed into smaller signaling molecules that regulate various phases of the plant’s life cycle.

Timing Mechanotransduction: Mechanically Dynamic Biomaterials Reveal the Temporal Hierarchy of YAP/TAZ Control Nodes

open access: yesAdvanced Science, EarlyView.
This work develops dynamically softening polyacrylamide hydrogels for time‐resolved imaging during continuous mechanical transitions. The study revealed that mechanotransduction is biphasic; YAP/TAZ inactivation is driven by early loss of the nucleocytoskeletal continuum connecting subnuclear adhesions, F‐actin, and the nuclear envelope, coupled with ...

A Mathematical model for Astrocytes mediated LTP at Single Hippocampal Synapses

open access: yes, 2012
Many contemporary studies have shown that astrocytes play a significant role in modulating both short and long form of synaptic plasticity. There are very few experimental models which elucidate the role of astrocyte over Long-term Potentiation (LTP ...

Mitochondrial and chloroplast stress responses are modulated in distinct touch and chemical inhibition phases [PDF]

open access: yes, 2016
Previous studies have identified a range of transcription factors that modulate retrograde regulation of mitochondrial and chloroplast functions in Arabidopsis (Arabidopsis thaliana).

A new alternative in plant retrograde signaling [PDF]

open access: yesGenome Biology, 2014
AbstractThe reduced or oxidized state of plastoquinone in chloroplasts regulates splicing in the nucleus to control nuclear gene expression in response to changing environmental conditions.

CRP Deficiency Rescues Periodontitis‐Induced Hippocampal Neurogenesis Impairment by Suppressing OPC‐Derived BMP4 Signaling in Rats

open access: yesAdvanced Science, EarlyView.
Chronic periodontitis elevates circulating CRP, which enters the hippocampus to upregulate BMP4 in oligodendrocyte precursor cells (OPCs), thereby impairing neurogenesis and inducing anxiety/depression‐like behaviors in rats. Counteracting this pathway, CRP deficiency helps confer functional resilience to OPCs.

Cell signaling dependence of rapid glucocorticoid-induced endocannabinoid synthesis in hypothalamic neuroendocrine cells

open access: yesNeurobiology of Stress, 2019
Glucocorticoids induce a rapid synthesis of endocannabinoid in hypothalamic neuroendocrine cells by activation of a putative membrane receptor. Somato-dendritically released endocannabinoid acts as a retrograde messenger to suppress excitatory synaptic ...
