Summary: To understand the regulation of sleep-wakefulness cycles, it is important to study the relationship between the preoptic area (POA) and lateral hypothalamic area (LHA), which have opposing roles in sleep-wakefulness regulation. This study revealed the direct connection between GABA- and galanin-producing neurons in the ventrolateral preoptic nucleus (VLPO) and orexin-producing neurons in the LHA. It also discovered that the VLPOGABA-LHA pathway plays a previously unknown role in the regulation of sleep and wakefulness.

Summary: The hypothalamic preoptic area (POA) plays a crucial role in regulating arousal states in both natural and drug-induced forms of unconsciousness. While known for promoting sleep and wake, the complexity and molecular heterogeneity of the POA make it challenging to distinguish between different populations of neurons involved in these processes.

Summary: The SDN-POA is a sexually dimorphic brain structure that is larger in males and is associated with mating preference. Microglia play a crucial role in reducing the size of the SDN in females by engulfing more neurons. Inhibiting microglia phagocytosis increases the SDN volume in females and affects their preference for male odors in adulthood.

Summary: Mammals regulate their body temperature by utilizing internal circadian clocks and thermosensitivity. The preoptic area of the hypothalamus houses temperature-sensitive circadian clocks that are influenced by temperature changes but not by light cues.

Summary: Sleep and body temperature are tightly interconnected in mammals, with the preoptic area of the hypothalamus playing a crucial role in regulating these behaviors. Recent research on sleep- and thermo-regulatory POA neurons has raised new questions about the overlap and pathways of these neurons and the role of signaling molecules in coordinating sleep and body temperature regulation.

Summary: In the guinea pig preoptic area (POA), most CB+ and CR+ neurons are GABAergic and express VGAT, while a fraction of them also express VGLUT. The majority of PV+ neurons express VGAT, and a similar proportion of them express VGLUT. This indicates that these neurons may have a dual GABA/glutamate phenotype.

Summary: This study found that injection of agmatine into the preoptic area (POA) of male rats induced hyperthermic responses associated with increased heat production and locomotor activity. The most effective injection sites were located in the medial preoptic area (MPA). Results suggest that agmatine injection can cause thermogenic, shivering, and locomotor responses by inhibiting warm-sensitive neurons in the POA.

Summary: In this paper, a deep learning network combined with the SD-ARX model framework is proposed to build a nonlinear system model. Different hybrid models, including RNN-ARX, CNN-ARX, and RNN-CNN-ARX, are built to extract the dynamic characteristics of nonlinear systems. Based on these models, three model-based predictive control strategies are designed, and the feasibility and effectiveness are validated through real-time control experiments.

Summary: A recent study has found that there are sex differences in response to general anesthesia, but the neural mechanisms behind this are unclear. This study showed that male mice were more sensitive to sevoflurane anesthesia and that estrogen receptor alpha in the medial preoptic area played a critical role in regulating sleep in males. Furthermore, pharmacological inhibition of estrogen receptor alpha eliminated sex differences in sevoflurane anesthesia.

Summary: This study investigated the effect of apelin-13 on different brain areas at varying doses, and found that it can induce lordosis behavior, with a more pronounced effect in the VMH of EB-primed rats, and only the 0.75 μg infusion of apelin in the POA induced significant lordosis at 120 and 240 min.

Summary: Nicotine exposure during development may affect the sexual differentiation of the developing brain, potentially influencing adult sexual behavior in rodents. This study found that developmental nicotine exposure had an impact on the sexual differentiation of the preoptic area (POA) in rats, with the normal sex differences in male sexual behavior and POA area eliminated in nicotine-treated animals. In neonates, nicotine exposure also induced changes in gene expression and DNA methylation levels at sexually-dimorphic regions, suggesting the involvement of epigenetic mechanisms in the masculinization of the rat POA.

Summary: This article investigates the genetic regulatory mechanisms of Drosophila intestinal stem cells. The study found that most target genes co-regulated by Esg and STAT show a consistent gene expression pattern. However, manipulating these validated targets in vivo rarely replicated the effects of manipulating Esg and STAT, suggesting the presence of complex genetic interactions among the downstream targets of these two master regulator genes.

Summary: Researchers found that conditional deletion of Robo2 in adult mice led to a significant loss of islet architecture without affecting beta cell identity or function, suggesting that Robo2 plays a role in actively maintaining adult islet architecture. Understanding the factors required for islet architecture maintenance is crucial for developing future diabetes therapies.

Summary: Knock-in reporter (KI) animals are essential for studying gene expression in biomedical research. This study developed a new strategy using minicircle technology and a minimal promoter to enhance knock-in events and establish stable KI transgenic reporter lines. The study also highlighted the importance of selecting the proper KI line due to potential inappropriate influence of genome editing on reporter gene expression.
