Receptor tyrosine kinases (RTKs) are membrane sensors that monitor alterations in the extracellular milieu and translate this information into appropriate cellular responses. Epidermal growth factor receptor (EGFR) is the most well-known model in which gene expression is upregulated by mitogenic signals through the activation of multiple signaling cascades or by nuclear translocation of the full-length EGFR protein. RON (Receptuer d'Origine Nantatise, also known as macrophage stimulating 1 receptor, MST1R) has recently gained attention as a therapeutic target for human cancer.

Langerhans cell histiocytosis (LCH) is characterized genetically by diverse gene mutations of the mitogen-activated protein kinase signaling cascade. BRAFN486_T491delinsK mutation is a rare mutation that involves the β2-αC ring domain, causing activation of the mitogen-activated protein kinase pathway, and is predicted to be resistant to the chemotherapy and BRAFV600E inhibitor in adult LCH cases. Here, we report a childhood LCH case with this novel BRAF mutation and had a good response to conventional chemotherapy.

Respiratory syncytial virus (RSV) is one of the most important etiologies of acute respiratory infections that cause bronchiolitis in children under 5 years of age. Treatments are expensive, no vaccine is available, and this is an important cause of hospitalization. Costimulatory molecules have been reported to be good inducers of antiviral type 1 immune response.

The vascular wilt fungus Verticillium dahliae is a destructive soil-borne pathogen that causes yield loss on various economically important crops. Membrane-spanning sensor protein SLN1 have been demonstrated to contribute to virulence in varying degrees among numerous devastating fungal pathogens. However, the biological function of SLN1 in V.

BRAF inhibitors (BRAFi) represent a cornerstone in melanoma therapy due to their high efficacy. However, the emergence of resistance causes a significant challenge to their clinical utility. This study aims to investigate the potential of diclofenac as a sensitizer for BRAFi therapy in melanoma and to elucidate its underlying mechanism.
