Polycomb repressive complex 1.1 restricts precocious myeloid differentiation of hematopoietic stem/progenitor cells and expansion of myeloid progenitors, thereby serving as a gatekeeper of emergency myelopoiesis and myeloid transformation.

A novel pathway of emergency myelopoiesis is induced by repetitive virus stimulation at peripheral barrier sites which bypasses the requirement of conventional pathways and expands myeloid infiltration in tissues.
The thioredoxin-1 (Trx1) system promotes inflammation by positively regulating both NLRP3 inflammasome responses, by detoxifying excessive ROS independently of Txnip and NF-κB binding to target DNA.
Chronic and excessive inflammation can lead to exhaustion of the supply of hematopoietic stem cells and to myeloid malignancies in mice, mimicking important aspects of the myelodysplastic syndrome found in humans.

In-silico modeling of gene and protein emergence reveals how colony-stimulating factors contributed to the evolution and functional adaptions observed in mammalian neutrophils.
