Summary: Global inactivation of IKK-alpha leads to defective lymph node formation and B cell maturation. IKK-alpha in distinct EC-derived compartments is uniquely required to promote B cell homeostasis and LN development, and LEC-intrinsic IKK-alpha is absolutely essential for LN formation.

Summary: ERK1/2 plays a complex role in LPS-induced inflammatory activation and permeability of human lung microvascular endothelial cells, with inhibition of ERK1/2 enhancing IL-6 and VCAM-1 production while promoting IL-6 production in monocytes. ERK1/2 activation limits IL-6 production by HMVEC but promotes HMVEC permeability, suggesting its important role in regulating endothelial cell inflammation and vascular permeability in sepsis and injury.

Summary: The study demonstrated that punicalagin has a protective effect on HUVECs activation through an endothelial-mediated mechanism, which may be used in the treatment of various disorders such as cancer, rheumatoid arthritis, and cardiovascular disease. This effect is achieved by reducing adhesion of monocyte cells to HUVECs, decreasing expression of ICAM-1 and VCAM-1, and inhibiting permeability, proliferation, migration, and tube formation in VEGF-induced HUVECs. Additionally, punicalagin suppresses IKK-mediated activation of NF-kappa B signaling and inhibits VEGFR2 activation and downstream p-PAK1.

Summary: The transcription factor family NF-kappa B plays a crucial role in inflammation and immunity. Live cell imaging has revealed the dynamic nature of NF-kappa B activation, including oscillations in its nuclear localization. This interdisciplinary research has provided insights into the heterogeneous response of NF-kappa B in different cell types and its impact on gene expression. Future steps in this field should focus on filling existing knowledge gaps.

Summary: The protein NONO is a multifunctional nuclear protein that regulates transcriptional regulation, mRNA splicing, and DNA repair. This study shows that NONO has a critical role in B-cell development and B-cell activation. Deletion of NONO impairs early B-cell development and B-cell maturation, as well as the activation of pathways involved in B-cell activation, such as ERK, AKT, and NF-kappa B.

Summary: This study reveals that USP4 plays a crucial role in the progression of esophageal squamous cell carcinoma (ESCC) by modulating proliferation, migration, and invasion. USP4 interacts with TAK1 and stabilizes its protein levels in ESCC cells. Additionally, USP4 promotes ESCC progression through the activation of the MEK/ERK signaling pathway.

Summary: Inflammatory pathways are activated in most glomerular diseases, with the induction of Rarres1 expression being a common molecular mechanism in chronic kidney diseases. The overexpression of Rarres1 in endothelial cells promotes kidney damage in a model of glomerulonephritis through the Nuclear Factor-kappa B signaling pathway, highlighting its pathogenic role in inflammation and fibrosis.

Summary: In this study, two arginine kinases (AKs) in Sarcoptes scabiei were found to play important roles in the host immune response. These AKs promote cell proliferation and inhibit cell apoptosis by activating the NF-κB signaling pathway and increasing the expression of Bcl-2 and Bcl-xl. Additionally, they also alter the immune balance by affecting the secretion of specific cytokines, participating in the allergic inflammation caused by S. scabiei.

Summary: Mice lacking the I kappa BNS protein exhibit impaired antibody responses to both T cell-independent and T cell-dependent antigens. Conditional knock-out mice with I kappa BNS ablation specifically in B cells show normal T cell populations and germinal center formation, but still have defective antibody responses to T cell-dependent antigens.

Summary: In this study, the regulatory pathway of miR-let-7b/TLR4/NF-kappa B in neutrophils was investigated. Overexpression of miR-let-7b down-regulated TLR4 expression and decreased proinflammatory factors while increasing anti-inflammatory factor in vitro. Treatment with miR-let-7b agomir in septic mice improved survival, reduced organ injuries, and inhibited neutrophil recruitment.

Summary: This study found that IQGAP1 is highly expressed in esophageal squamous cell carcinoma (ESCC) and is positively correlated with MMP2 expression. IQGAP1 overexpression promotes the growth, migration, and invasion of ESCC cells, upregulates MMP2 expression, and increases NF-kappa B expression and nuclear localization. Treatment with PDTC or JSH-23 can reverse IQGAP1-mediated cell migration and invasion ability, as well as MMP2 expression.

Summary: Post-COVID-19 Condition (PCC) is a multisystemic syndrome that persists for months after SARS-CoV-2 infection, affecting cognitive function and neuropsychiatric features. A study on COVID-19 survivors in Brazil found that these patients experienced significant difficulties in overall cognition, memory, working memory, and inhibitory control, as well as fatigue, anxiety, and depressive symptoms. In addition, elevated levels of inflammatory markers in the blood were associated with brain microstructural damage and cognitive impairments.

Summary: Neuronanomedicine is a multidisciplinary field that aims to develop innovative nanotechnologies for the treatment of neurodegenerative disorders. Nanoparticles are an important component of neuronanomedicine, as they can improve drug properties and enhance safety and delivery across the blood-brain barrier. However, a major challenge for neuronanomedicine translation is the poor understanding of bio-nano interactions, partly due to inconsistent reporting in published works. This review provides specific recommendations to guide researchers in harnessing the unique properties of nanoparticles for breakthrough treatments of Alzheimer's and Parkinson's disease.

Summary: Depressed patients show changes in immune-inflammatory markers in their blood and cerebrospinal fluid. The Choroid Plexus, located at the base of the brain ventricles, plays a key role in regulating the exchange of substances between the brain and immune cells. Patients with bipolar disorder or major depressive disorder have larger Choroid Plexus volumes compared to healthy controls. Age and levels of circulating cytokines are associated with Choroid Plexus volumes in the clinical groups.

Summary: There is a strong male bias in many neurodevelopmental disorders such as autism spectrum disorder, but the mechanisms behind this bias are unknown. Infection during the perinatal period increases the risk of neurodevelopmental disorders. Using a mouse model, researchers found that early-life immune activation only induced deficits in social behaviors in male mice. These behavioral changes were associated with alterations in microglial immune signaling, mitochondrial morphology, gene expression, and function specifically in microglia, the brain's innate immune cells. Furthermore, the vulnerability to early-life immune activation and its effects on behavior and microglial mitochondria were programmed by the male-typical perinatal gonadal hormone surge. These findings highlight the role of microglia-specific mechanisms shaped by early developmental events in regulating male social behavior throughout lifespan.

Summary: Cytokines, such as interleukin-15 (IL-15), play important roles in modulating the central nervous system (CNS). In this study, the authors found that exposure to IL-15 enhances GABA release and reduces glutamatergic currents in hippocampal slices. Chronic treatment with IL-15 has negative effects on memory formation. Serotonin is involved in mediating these effects, as a selective 5-HT3A receptor antagonist prevents the effects on inhibitory neurotransmission and improves performance in a memory test.
