Previously, we developed a dynamic magnetic field (DMF) device using neodymium magnets that induced c-fos expression in cortical neurons, while activity-regulated cytoskeleton-associated protein (Arc), and brain-derived neurotrophic factor (BDNF) remained unaffected. The precise signal transduction pathway for c-fos induction under DMF was unclear. This study aimed to investigate the mechanism of immediate early gene (IEG) induction using calcium channel blockers (CCBs).

Combined and highly active anti-retroviral therapies (cART) have transitioned HIV into a more chronic disease. Roughly half of people living with HIV (PLWH) still experience neurocognitive disorders, albeit less severely than in the pre-cART era. Sex-related effects on memory/cognition remain understudied, although the percentage of PLWH that are female has increased.

The dopamine D1-like receptor is a dopamine (DA) receptor regulating diverse brain functions. Once the dopamine D1-like receptor is activated, it induces activation of the Protein Kinase A (PKA) that phosphorylates the cAMP Response Element-Binding (CREB) transcription factor, which once active elicits the expression of the critical synaptic elements Activity-regulated cytoskeleton-associated (Arc) and the Brain-Derived Neurotrophic Factor (BDNF). The temporality and subcellular localization of proteins impact brain function.

Activity-regulated cytoskeleton-associated protein (Arc) forms virus-like capsids for mRNA transport between neurons. Unlike HIV-1 Group-specific Antigen (Gag), which uses its Nucleocapsid (NC) domain to bind HIV-1 genomic mRNA, mammalian Arc lacks the NC domain, and their direct mRNA binding interactions remain underexplored. This study examined rat Arc's binding to rat Arc 5' UTR (A5U), HIV-1 5' UTR (H5U), and GFP mRNAs, revealing weak binding with no significant preference.

Intermittent hypoxia (IH), a major pathophysiologic alteration in obstructive sleep apnea syndrome (OSAS), is an important contributor to cognitive impairment. Increasing research suggests that melatonin has anti-inflammatory properties and improves functions related to synaptic plasticity. However, it is unclear whether melatonin has a protective effect against OSAS-induced cognitive dysfunction in aged individuals and the involved mechanisms are also unclear.
