Immunological features of EGFR-mutant non-small cell lung cancer and clinical practice: a narrative review.

Immune checkpoint inhibitors (ICIs) have significantly improved outcomes for patients with advanced driver-negative non-small cell lung cancer (NSCLC). However, targeted therapy remains the preferred treatment for advanced driver-positive NSCLC, including cases with epidermal growth factor receptor (EGFR) mutations. Considering the variability in EGFR-mutant NSCLC, including expression levels of programmed cell death ligand 1 (PD-L1), tumor mutation burden (TMB), and other immunological features, the application of immunotherapy in this group is still a subject of investigation.

Mechanism of action of the nucleotide-binding oligomerization domain-like receptor protein 3 inflammasome and its regulation in liver injury.

Nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) is a cytosolic pattern recognition receptor that recognizes multiple pathogen-associated molecular patterns and damage-associated molecular patterns. It is a cytoplasmic immune factor that responds to cellular stress signals, and it is usually activated after infection or inflammation, forming an NLRP3 inflammasome to protect the body. Aberrant NLRP3 inflammasome activation is reportedly associated with some inflammatory diseases and metabolic diseases.

RNA-binding protein HNRNPD promotes chondrocyte senescence and osteoarthritis progression through upregulating FOXM1.

Osteoarthritis (OA) is a common age-related disease that is correlated with a high number of senescent chondrocytes in joint tissues. Heterogeneous nuclear ribonucleoprotein D (HNRNPD) is an RNA-binding protein whose expression imbalance is associated with cell senescence, but the role of HNRNPD in the occurrence and development of OA has not been reported. In this study, HNRNPD was found to be associated with the chondrocyte senescence process.

Diagnostic Accuracy of Computational Fluid Dynamics-Based Fractional Flow Reserve Derived From Coronary Angiography: The ACCURATE Study.

Tumor cell membrane-based vaccines: A potential boost for cancer immunotherapy.

Because therapeutic cancer vaccines can, in theory, eliminate tumor cells specifically with relatively low toxicity, they have long been considered for application in repressing cancer progression. Traditional cancer vaccines containing a single or a few discrete tumor epitopes have failed in the clinic, possibly due to challenges in epitope selection, target downregulation, cancer cell heterogeneity, tumor microenvironment immunosuppression, or a lack of vaccine immunogenicity. Whole cancer cell or cancer membrane vaccines, which provide a rich source of antigens, are emerging as viable alternatives.
