Project description:Genome-wide identification of RNA polymerase (RNAP) binding sites were performed in Klebsiella pneumoniae MGH 78578 (KP). Anti-RNAP is used to capture the RNAP in KP. ChIP-chip was performed on tiling array specifically made for KP.

Project description:The global rise of antibiotic-resistant Klebsiella pneumoniae (KP) underscores an urgent need for novel preventive strategies. Although human mesenchymal stem/stromal cells (hMSCs) exhibit immunomodulatory and antimicrobial properties in preclinical model, their clinical efficacy remains limited. We hypothesized that early prophylactic hUC-MSCs administration in high-risk populations could prime the pulmonary immune microenvironment, conferring protection against KP infection. This study evaluated the efficacy and mechanisms of hUC-MSC-based prophylaxis in a murine KP lung infection model.
