In men, lower urinary tract dysfunction (LUTD) is commonly linked to prostatic collagen accumulation through inflammation-mediated mechanisms. Researchers used 8- to 10-week-old male reporter mice, exposed to either sterile phosphate buffered saline (PBS) or Escherichia coli, to identify that circulating Lyz2+S100a4+Gli1+ myeloid-derived cells are recruited to the prostate to drive inflammation and collagen synthesis. Researchers also used 8- to 10-week-old male Ccr2‑/ - null and Ccr2+/- control mice, exposed to either sterile PBS or E. coli, to determine if Ccr2 is necessary for the fibrotic response to prostatic uropathogen infection. Results demonstrated that CCR2+ cells mediate the collagen abundance and fibrotic response to prostate inflammation. This study elucidates the cell types underlying prostate fibrosis and can be utilized to develop targeted therapies. Supported by ORIP (T32OD010957), NCI, NIDDK, and NIEHS.
The Monarch Initiative in 2024: An Analytic Platform Integrating Phenotypes, Genes and Diseases Across Species

The Monarch Initiative aims to bridge the gap between the genetic variations, environmental determinants, and phenotypic outcomes critical for translational research. The Monarch app provides researchers access to curated data sets with information on genes, phenotypes, and diseases across species and advanced analysis tools for such diverse applications as variant prioritization, deep phenotyping, and patient profile matching. Researchers describe upgrades to the app, including scalable cloud-based infrastructure, simplified data ingestion and knowledge graph integration systems, enhanced data mapping and integration standards, and a new user interface with novel search and graph navigation features. A customized plugin for OpenAI’s ChatGPT allows the use of large language models to interrogate knowledge in the Monarch graph and increase the reliability of the responses of Monarch’s analytic tools. These upgrades will enhance clinical diagnosis and the understanding of disease mechanisms. Supported by ORIP (R24OD011883), NLM, and NHGRI.
