Involvement of MST1/mTORC1/STAT1 activity in the regulation of B-cell receptor signalling by chemokine receptor 2.

Background: CCR2 is involved in maintaining immune homeostasis and regulating immune function. This study aims to elucidate the mechanism by which CCR2 regulates B-cell signalling.

Methods: In Ccr2-knockout mice, the development and differentiation of B cells, BCR proximal signals, actin movement and B-cell immune response were determined.

Abelson tyrosine kinase controls BCR signalling and B-cell differentiation by promoting B-cell metabolism.

As a nonreceptor tyrosine kinase, Abelson tyrosine kinase (c-Abl) was first studied in chronic myelogenous leukaemia, and its role in lymphocytes has been well characterised. c-Abl is involved in B-cell development and CD19-associated B-cell antigen receptor (BCR) signalling. Although c-Abl regulates different metabolic pathways, the role of c-Abl is still unknown in B-cell metabolism.

Sodium butyrate ameliorates Schistosoma japonicum-induced liver fibrosis by inhibiting HMGB1 expression.

Schistosomiasis is a prevalent zoonotic parasitic disease caused by schistosomes. Its main threat to human health is hepatic granuloma and fibrosis due to worm eggs. Praziquantel remains the first choice for the treatment of schistosomiasis but has limited benefit in treating liver fibrosis.

Capsaicin Protects Against Lipopolysaccharide-Induced Acute Lung Injury Through the HMGB1/NF-κB and PI3K/AKT/mTOR Pathways.

Purpose: Capsaicin (8-methyl-N-geranyl-6-nonamide; CAP) is an alkaloid isolated from chili peppers, which has complex pharmacological properties, including beneficial effects against various diseases. The aim of this study was to investigate the role of CAP in lipopolysaccharide (LPS)-induced acute lung injury (ALI), and the possible underlying mechanisms.

Materials And Methods: ALI was induced by intranasal administration of LPS (0.

CCL2 regulation of MST1-mTOR-STAT1 signaling axis controls BCR signaling and B-cell differentiation.

Chemokines are important regulators of the immune system, inducing specific cellular responses by binding to receptors on immune cells. In SLE patients, decreased expression of CCL2 on mesenchymal stem cells (MSC) prevents inhibition of B-cell proliferation, causing the characteristic autoimmune phenotype. Nevertheless, the intrinsic role of CCL2 on B-cell autoimmunity is unknown.

The role of microRNAs in the pathogenesis, grading and treatment of hepatic fibrosis in schistosomiasis.

Schistosomiasis is a prevalent parasitic disease worldwide. The main pathological changes of hepatosplenic schistosomiasis are hepatic granuloma and fibrosis due to worm eggs. Portal hypertension and ascites induced by hepatic fibrosis are usually the main causes of death in patients with chronic hepatosplenic schistosomiasis.
