Background: Chronic rhinosinusitis (CRS) is a global health issue, with some patients experiencing anxiety and depression-like symptoms. This study investigates the role of HMGB1 in anxiety and depression-like behaviors associated with the microglial Notch1/Hes-1 pathway in CRS mice.
Methods: A CRS mouse model was developed, and behavioral assessments were conducted to evaluate anxiety and depression-like behaviors.

Purpose: This study aimed to compare systemic immune responses and metastatic effects induced by radiofrequency ablation (RFA) and irreversible electroporation (IRE) in murine tumor models. We assessed cytokine production, growth of treated and untreated metastatic tumors, and synergy with immune checkpoint inhibitors (ICIs).
Materials And Methods: Hep55.

Tissue inhibitor of matrix metalloproteinase 1 (TIMP1) is a multifaceted, cytokine-like bioactive molecule whose levels are elevated in a wide range of inflammatory diseases and are associated with prognosis. Additionally, TIMP1 may play a role in driving systemic inflammation. TIMP1 immunohistochemistry and TIMP1 serum concentrations were analyzed in a cohort of 776 colorectal cancer patients.

Liver fibrosis is a critical liver disease that can progress to more severe manifestations, such as cirrhosis, yet no effective targeted therapies are available. Here, we identify that ATF4, a master transcription factor in ER stress response, promotes liver fibrosis by facilitating a stress response-independent epigenetic program in hepatic stellate cells (HSCs). Unlike its canonical role in regulating UPR genes during ER stress, ATF4 activates epithelial-mesenchymal transition (EMT) gene transcription under fibrogenic conditions.

Background: The multifunctional cytokine interleukin-6 (IL-6) plays a pivotal role in chronic and acute inflammatory responses, underscoring the importance of accurately determining IL-6 levels for early diagnosis, prevention, and treatment of inflammation.
Results: This study developed a versatile and innovative single-particle surface-enhanced Raman spectroscopy (SERS) sensing platform for the precise and sensitive quantification of IL-6 in complex samples using a novel one-pot synthesized, silver ions-doped three-dimensional porous gold microparticles (PGMs) with abundant hot spots for robust SERS enhancement. By rationally designing rich cytosine-Ag-cytosine base pairs between IL-6 aptamers and complementary chains on the PGMs, we harnessed the SERS-enhancing effect to achieve highly sensitive and specific IL-6 quantification within a wide range of 10 to 10 mg/mL and a limit of detection (LOD) of 0.
