Summary: This study identifies the role of the protein Rai14 in the regulation of dendritic spine dynamics and its association with stress-induced depressive-like behaviors. Rai14-deficient neurons exhibit reduced dendritic spine density and impaired synaptic activity. Rai14 forms a complex with Tara, preventing its degradation and accumulating in the dendritic spine neck, enhancing spine maintenance. Rai14 deficiency also alters gene expression relevant to depression and increases depressive-like behaviors.

Summary: The distribution of neurogenesis in the dentate gyrus is positionally associated with active excitatory neurons and dissociated from a type of interneuron with high-burst tendency. This suggests that behaviorally relevant activity of excitatory-inhibitory neuronal circuits can define a microenvironment stimulating/inhibiting neurogenesis, contributing to strategic recruitment of new neurons for modification of functionally relevant neural circuits.

Summary: This study reveals the crucial role of mitochondria in neural progenitors and their association with the protein amyloid-beta, which is linked to Alzheimer's disease. Mitochondrial dysfunction inhibits neuronal differentiation, leading to deficits in adult hippocampal neurogenesis and cognitive function. The research suggests that lysine demethylase 5A epigenetically suppresses differentiation in response to mitochondrial damage.

Summary: Heavy alcohol consumption leads to neuronal cell death and cognitive impairment. The production of ceramide, a sphingolipid metabolite, may be responsible for the neuronal cell death induced by ethanol. However, the molecular mechanisms underlying this process have not been fully understood.

Summary: Adolescence is a sensitive developmental period during which alcohol use can lead to long-term social impairments, particularly in males. However, the neuronal underpinnings for this sex-specific effect are not well understood. This study aimed to investigate whether social anxiety-like alterations in adolescent male rats following intermittent ethanol exposure are accompanied by changes in neuronal activation in brain regions associated with social behavior. The results suggest that AIE produces sex-specific social impairments potentially driven by differential neuronal activation states in specific brain regions.

Summary: Cellular senescence is a stable cell cycle arrest accompanied by a senescence-associated secretory phenotype (SASP), and calcium signaling has been identified as a key regulator in cellular senescence. This study reveals that the nuclear receptor RXRA inhibits the endoplasmic reticulum calcium release channel ITPR2 to control intracellular calcium signaling during cellular senescence. Additionally, the zinc finger protein ZBTB17 is found to interact with RXRA and play a role in regulating cellular senescence.

Summary: Infection with Toxoplasma gondii alters norepinephrine levels by down-regulating dopamine ss-hydroxylase (DBH) gene expression. Intracerebral injection of TINEVs induces DBH down-regulation and disrupts catecholaminergic signalling. TINEV treatment also leads to hypermethylation upstream of the DBH gene and the presence of an antisense lncRNA to DBH in purified TINEV preparations.

Summary: Chronic stress can induce depressive-like behavior and inhibit adult hippocampal neurogenesis. Chronic corticosterone treatment decreases the proliferation and survival of neural stem cells, impairs the migration of newborn neurons, and increases neuronal autophagy. Inhibiting hyperactive neuronal autophagy can reverse the decrease in neuronal brain-derived neurotrophic factor levels, rescue neurogenesis, and exert antidepressant effects.

Summary: The study introduces a new assay, FLEA, to accurately measure incentive motivation in Drosophila by adjusting electrical current levels in each feeding well. It is found that external incentives and internal motivational state can drive flies to overcome higher currents for better food, and current perception is not discounted as the flies become more food-deprived. Additionally, it is demonstrated that neuropeptide F plays a role in sensory processing of electrical current in fruit flies.

Summary: The study identified serine protease HTRA1 as a novel podocyte antigen in primary membranous nephropathy (MN) patients. Anti-HTRA1 antibodies in patients with HTRA1-associated MN were predominantly IgG4 and seemed to correlate with clinical disease activity. Screening of 118 quadruple-negative patients revealed a 4.2% prevalence of HTRA1-associated MN.

Summary: The intracellular chloride concentration in the small ventral lateral (sLN(v)) pacemaker neurons of fruit flies can regulate the length of the circadian period by influencing the activation of the WNK-Fray signaling pathway and the activation of an inwardly rectifying potassium channel. This finding helps us understand the regulatory mechanism of circadian rhythms.

Summary: The APOL1 genotypes can modify the association between dietary potassium and CKD progression. Higher urinary potassium excretion is associated with lower risk of CKD progression in individuals with high-risk APOL1 genotypes, and higher risk of CKD progression in individuals with low-risk APOL1 genotypes.
