Summary: FKBP5 is a protein that inhibits the translocation of the glucocorticoid receptor, and its expression is related to psychiatric disorders. Deletion of FKBP5 in the brain makes rodents resilient to stress-induced depression. Our study found that FKBP5 deletion in the hippocampus causes changes in synaptic transmission and insensitivity to activated glucocorticoid receptors.

Summary: The study indicates that hippocampal mitogen-activated protein kinase phosphatase-1 (MKP-1) plays a crucial role in connecting brain dysfunction with systemic illness under stress. Chronic corticosterone (CORT) treatment results in behavioral emotionality and systemic pathophysiological effects, including elevated renal inflammation protein markers.

Summary: Copper is essential for human health, but chronic stress can lead to disorders in copper metabolism. In this study, it was found that corticosterone impairs copper transport by down-regulating intestinal CTR1 expression via GR-mediated transcriptional inhibition. This study provides a theoretical basis for regulating copper homeostasis under chronic stress.

Summary: Abnormal activation of the stress-response system in early life can cause long-term neurological changes. High levels of glucocorticoids can promote oxidative damage in the brain. Selenium, an essential trace element, can mitigate this damage by synthesizing antioxidant selenoproteins. This study demonstrates that early life exposure to excess glucocorticoid levels can alter selenoprotein levels in the developing brain.

Summary: The study compared the effects of two common maternal deprivation schedules on cognitive ability in young rats, finding that daily separation impaired spatial learning, while randomly spaced separation did not affect maze performance. Additionally, some biological effects were observed, such as differences in body weight and thymus weight normalized by body weight.

Summary: The use of glucocorticoid medications can cause metabolic side effects such as overeating, weight gain, and insulin resistance. The hypothalamus, a regulator of feeding behavior and energy expenditure, is responsive to glucocorticoids and may play a role in metabolic defects. Selenium has been found to counter the effects of glucocorticoids and is important for hypothalamic function. This study aimed to investigate if selenium could protect hypothalamic cells from dysfunction caused by glucocorticoid exposure.

Summary: CORT inhibits Lhcgr expression in mouse ovarian granulosa cells (GCs), leading to impaired follicular development. The effect of CORT is mediated by its receptor Nr3c1 in GCs. Nr3c1 may regulate Lhcgr transcription by inhibiting the expression of Lhcgr transcription factors AP1 and Creb.

Summary: Binge drinking causes rapid changes in neuroimmune gene expression and activates the hypothalamic-pituitary-adrenal axis. Inhibiting the synthesis of corticosterone can prevent the gene expression changes caused by ethanol. Ethanol can suppress the expression of IL-1 beta and TNF alpha in the hippocampus through the release of corticosterone. These findings provide potential interventions to reduce alcohol intake and alleviate ethanol-induced neuroimmune activation.

Summary: The study analyzed the effects of corticosterone supplementation on feather corticosterone concentrations (fCORT) in layer pullets, finding that increased corticosterone levels led to decreased body weight, shorter and lighter feathers, and a delayed molt. The results suggest that fCORT measurement can be a useful tool for evaluating long-term stress in chickens and may have implications for animal welfare research.

Summary: The study found that different doses of corticosterone have dual effects on hippocampal cell survival and spatial memory in rats, with low doses improving cell survival and memory, while high doses may have the opposite effect. This suggests that endogenous glucocorticoids have neuroprotective and neurotoxic effects depending on the threshold level, and caution should be exercised with higher doses after traumatic brain injury.

Summary: In this longitudinal study, it was found that IL6 levels are negatively correlated with the functional status and respiratory function in ALS patients, specifically in those carrying the IL6R(358)Ala variant. This suggests that the association between IL6 and ALS is driven by genetic factors, and targeted therapeutic approaches may be more effective in this subset of patients.

Summary: The study aimed to investigate the safety, tolerability, and target engagement of tocilizumab in ALS patients. Results showed a significant decrease in CRP levels in the treatment group, with potential CSF effects associated with IL-6R genotype. However, no differences were observed between groups in terms of PBMC gene expression and clinical measures.

Summary: The apple-shaped anatomical pattern that comes with visceral obesity increases the risk of multiple chronic diseases, including those that affect the brain. However, it is challenging to distinguish between the consequences of visceral obesity and the metabolic and cardiovascular pathologies associated with adiposity. This review summarizes the current literature on the relationship between adipose tissue distribution and cognition, particularly in preclinical models, and discusses the potential role of tissue- and cell type-specific insulin resistance.

Summary: The nervous and immune systems are closely related and influence each other. Immune cells play important roles in shaping and pruning neuronal synapses, as well as in neuro-development and disease pathology. The maintenance of the blood-brain barrier, regulated by extracellular matrix components, can be disrupted after brain insult, leading to changes in composition. These changes and immune infiltration have detrimental effects on neurophysiology and are characteristic of certain diseases.
