Hutchinson-Gilford Progeria syndrome (HGPS) serves as a prominent model for Progeroid syndromes, a group of rare genetic disorders characterized by accelerated aging. This review explores the genetic basis, clinical presentation, and complications of HGPS. HGPS is caused by mutations in the LMNA gene, resulting in the production of a defective structural protein, prelamin A.

Bacterial cells secrete extracellular vesicles (EVs), the function of which is a matter of intense investigation. Here, we show that the EVs secreted by the human pathogen (pneumococcus) are associated with bacterial DNA on their surface and can deliver this DNA to the transformation machinery of competent cells. These findings suggest that EVs contribute to gene transfer in Gram-positive bacteria and, in doing so, may promote the spread of drug resistance genes in the population.

Article Synopsis
  • Terrestrial and aquatic environments contaminated with animal urine can spread Leptospira, which causes leptospirosis in both humans and animals, but the factors influencing its growth and virulence are not fully understood.
  • A new strain of Leptospira interrogans, named KeTo, was isolated from sewage in India and can oxidize various organic acids, demonstrating susceptibility to ethyl acetoacetate that inhibits its growth and biofilm formation.
  • Genetic analysis revealed that KeTo shares a high similarity to pathogenic strains and has specific genes for utilizing acetoacetate, indicating its metabolic capabilities and the need for further research on its growth inhibition.
