Innovative studies have uncovered critical molecular and cellular mechanisms across various diseases. Senescent cells are characterized as metabolically active yet dysfunctional contributors to aging and cancer progression, prompting development of senolytic therapies. Advances in gene editing trace the evolutionary origin of CRISPR Type V RNA-splitting systems. New insights into immune cell subsets and molecular markers offer avenues for improved stratification and treatment of hematologic malignancies and neurodegenerative diseases.
