Explores NAMPT's role in promoting myeloid differentiation in hematopoietic stem cells, indicating a new therapeutic target in Crohn's disease.

The research aims to investigate how eNAMPT influences myeloid differentiation in hematopoietic stem cells during Crohn’s disease progression.
Used a DNBS-induced colitis model in BALB/c mice.
Administered recombinant eNAMPT to mimic systemic levels seen in Crohn’s disease.
Analyzed colon, blood, and bone marrow samples using flow cytometry and various RNA sequencing techniques.
Administration of eNAMPT resulted in increased weight loss and worse colon damage.
Enhanced fibroblast activation and collagen deposition were observed following eNAMPT treatment.
Increased myeloid cell infiltration and expansion of hematopoietic compartments were noted in treated mice.

Travelli et al. (2026) studied this question.
