Published: February 2024

Background: Phage therapy could play an important role in the bacterial pneumonia. However, the exact role of phage therapy in bacterial pneumonia is unclear to date.

Aim: The current study aims to find out the role of phage therapy in preclinical models of bacterial pneumonia.

Methods: The studies were searched in databases with proper MeSH terms along with Boolean operators and selected based on eligibility criteria as per the PRISMA guidelines. The Odd Ratio (OR) was calculated with a 95% confidence interval and the heterogeneity was also calculated. The funnel plot was used to conduct a qualitative examination of publication bias.

Results: The OR was observed to be 0.11 (0.04, 0.27)] after 24 hrs, 0.11 [0.03, 0.34] after 7 days and 0.04 [0.01, 0.15] after 10 days that showed a significant role of phage therapy in reduction of deaths in the bacterial pneumonia models as compared to the placebo group. However, after 48hrs, a non-significant reduction was observed.

Conclusion: There was a significant role of phage therapy in the reduction of deaths in the bacterial pneumonia models.

Background: Immunotherapy is beneficial for some colorectal cancer (CRC) patients, but immunosuppressive networks limit its effectiveness. Cancer-associatedfibroblasts (CAFs) are significant in immune escape and resistance toimmunotherapy, emphasizing the urgent need for new treatment strategies.

Methods: Flow cytometric, Western blotting, proteomics analysis, analysis of public database data, genetically modified cell line models, T cell coculture, crystal violetstaining, ELISA, metabonomic and clinical tumour samples were conducted to assess the role of EDEM3 in immune escape and itsmolecular mechanisms.

Although immune checkpoint inhibitors have changed the treatment paradigm for non-small cell lung cancer (NSCLC), not all patients benefit from them. Therefore, there is an urgent need to explore novel immune checkpoint inhibitors. Neuropilin-1 (Nrp-1) is a unique immune checkpoint capable of exerting antitumor effects through CD8 T cells.

Article Synopsis
  • Quorum sensing (QS) regulates various bacterial adaptations to environmental changes and may influence phage infections, but current knowledge about this interaction is incomplete.
  • A novel phage, BUCT640, was characterized as having a unique morphology and depended on Psl polysaccharides for adsorption, revealing how bacterial QS pathways affect phage sensitivity.
  • The study discovered that QS could inhibit phage adsorption by altering biofilm thickness, suggesting that disrupting QS could enhance phage therapy efficacy against drug-resistant bacterial infections.

Article Synopsis
  • Acinetobacter baumannii, especially the carbapenem-resistant strains (CRAB), is a critical pathogen linked to antimicrobial resistance (AMR) and is prioritized by the WHO.
  • Phage therapy is being explored as a potential treatment for CRAB infections due to increasing resistance to conventional antibiotics.
  • A newly isolated lytic phage, vAbaIN10, exhibits effective lytic activity against CRAB in various conditions and shows promise in advancing treatment options for multidrug-resistant infections.
