Summary: The transition from acute to chronic pain leads to maladaptive brain remodeling and sensory hypersensitivity. This study found time-dependent plasticity of locus coeruleus (LC) neurons related to the site of injury and discovered the involvement of the LC -> dorsal reticular nucleus (DRt) pathway in chronic pain. Lidocaine blockade of LC ipsilateral to the lesion increased cold allodynia and reversed pain-induced depression. Inactivation of the LCcontra -> DRt(contra) pathway produced consistent analgesia in chronic pain and induced depressive-like behavior in naive animals.

Summary: There is a strong comorbidity between chronic pain and depression. The activation of noradrenergic locus coeruleus neurons is closely related to pain and depression. The time of injury also affects the symptoms, with early injury causing sensory hypersensitivity and long-term pain leading to depressive-like behavior.

Summary: Long-term nerve injury leads to increased spontaneous activity and exacerbated noxious-evoked responses in the locus coeruleus to stimulation of nerve-injured and even uninjured hindpaws, coinciding temporally with the development of depressive and anxiogenic-like behavior.

Summary: Insomnia is the second most common mental disorder, yet progress in understanding its underlying neurobiological mechanisms has been limited. This review explores the definition, prevalence, and susceptibility factors of insomnia, including genetic variants, early life stress, major life events, and brain structure and function. The proposed model suggests that in individuals vulnerable to developing insomnia, the locus coeruleus may be more sensitive to salience network input, leading to a spiral of hyperarousal and impaired sleep.

Summary: A new study reveals that infra-slow cortical norepinephrine oscillations play a crucial role in shaping the micro-structure of sleep and transitions between wakefulness, micro-arousals, and REM sleep. Furthermore, prolonged descending phases of these oscillations enhance the occurrence of spindle-rich intermediate sleep, which is involved in memory consolidation.

Summary: Astrocytes in the spinal dorsal horn have increased Ca2+ levels following intraplantar injection of formalin, with mechanisms regulated by descending noradrenergic signals. The Ca2+ response can be suppressed by ablating locus coeruleus-NAergic neurons projecting to the SDH or by losing alpha(1A)-adrenaline receptors in astrocytes.

Summary: Growing evidence suggests that the histamine system could be a promising target for the management of neuropathic pain. This study investigated the role of H4R in the anti-hyperalgesic action of the H3R antagonist GSK189254 in a mouse model of spared nerve injury (SNI). The results demonstrate the selective contribution of H4R to the attenuation of hypernociceptive behavior induced by the H3R antagonist, which could help identify innovative therapeutic interventions for neuropathic pain.

Summary: Nicotine can suppress mechanical hypersensitivity in central post-stroke pain by activating orexinergic neurons. By promoting neuronal activity, nicotine inhibits inflammation and neuropathic pain, reducing mechanical hypersensitivity. These findings suggest that nicotine may suppress pain in post-stroke patients by activating the descending pain control system through orexin neurons.

Summary: This study examined the effects of neuropathic pain on noradrenergic neurons in the locus coeruleus (LC) and found that neuropathic pain leads to an increase in excitatory synapse markers and a decrease in mitochondrial and lysosomal densities. Long-term pain also activates apoptosis.

Summary: Depression, anxiety, and aggression are closely associated with neuropathic pain. Effective treatment of these comorbidities can enhance pain management outcomes. The study examined the impact of antidepressants, benzodiazepine anxiolytics, and hypnotics on the intensity of depression, anxiety, and aggression in patients with neuropathic pain. The findings indicated that depression was well managed, but anxiety remained a potential treatment problem for these patients.

Summary: The locus coeruleus-noradrenergic system plays a crucial role in modulating pain and its comorbidity with anxiety and depressive disorders. However, the mechanisms underlying these effects are not fully understood. Novel research tools have helped redefine the locus coeruleus system and have shown its functional heterogeneity. This review summarizes the available data on the efferent activity of the locus coeruleus-noradrenergic system in relation to pain and its comorbidity with anxiodepressive disorders.

Summary: This study examined the relationship between plasma levels of BDNF/NGF and symptom severity in first-episode schizophrenia patients in remission. The results showed significant correlations between BDNF/NGF levels and symptom severity, but they were not predictive of relapse. These findings suggest that BDNF and NGF may serve as potential biomarkers for long-term severity in schizophrenia.

Summary: This study analyzed the plasma oxytocin and prolactin levels in FEP patients and found that low oxytocin, high prolactin, poor premorbid IQ, and sustained attention deficits are associated with FEP, indicating potential therapeutic targets. Further research in these biological and cognitive domains could lead to improved outcomes for FEP patients, possibly with gender-specific strategies.

Summary: This study evaluated the impact of serum from asymptomatic COVID-19 individuals on circulating angiogenic cells (CACs) using a proteomics-based quantitative approach. The results confirmed that SARS-CoV-2 infection in asymptomatic individuals caused protein level changes related to coagulation and inflammatory processes. Additionally, certain proteins were up-regulated only in CACs treated with serum from asymptomatic patients during the highest peak of infection. These findings provide insight into the effects of SARS-CoV-2 infection and the development of potential treatment methods.

Summary: By analyzing the association between blood co-expression modules and clinical data, we found that certain modules were correlated with clinical manifestations of schizophrenia, showing overlap with gene expression analysis in brain tissues. The hub genes in these modules were involved in multiple signaling pathways related to schizophrenia, suggesting their significant role in the development of the disease. These genes could potentially serve as targets for the development of peripheral biomarkers for schizophrenia.

Summary: This study aimed to investigate the relationship between relapse, cognitive function, and cognitive reserve in schizophrenia patients. The results showed that higher personal cognitive reserve mitigated the negative effects of relapse on attention performance, while higher cognitive reserve (both personal and familial) improved processing speed and visual memory in patients who did not relapse. These findings provide evidence for the protective effect of cognitive reserve over the course of the illness.
