PU.1, a Shared Transcriptional Regulator of Innate and Adaptive Immune Cell Fates

PU.1, a shared transcriptional regulator of innate and adaptive immune cell fates.

Killer Cell Immunoglobulin-Like Receptors Influence the Innate and Adaptive Immune Responses

Natural killer (NK) cells are a subset of lymphocytes which play a crucial role in early innate immune response against infection and tumor transformation. Furthermore, they secrete interferon-γ (IFN-γ) and tumor necrosis factor (TNF) prompting adaptive immu-nity. NK cells distinguish the unhealthy cells from the healthy ones through an array of cell-surface receptors. Human NK cells use inhibi...

A recurrent network involving the transcription factors PU.1 and Gfi1 orchestrates innate and adaptive immune cell fates.

The transcription factor PU.1, encoded by the Sfpi1 gene, functions in a graded manner to regulate macrophage versus B cell generation; its higher concentration favors the macrophage fate. We demonstrated that Gfi1 reciprocally promoted B cell fate choice at the expense of myeloid progeny. Gfi1(-/-) multipotential progenitors (MPPs) were unable to constrain the expression of PU.1 because Gfi1 f...

Single cell transcriptional analysis reveals novel innate immune cell types

Single-cell analysis has the potential to provide us with a host of new knowledge about biological systems, but it comes with the challenge of correctly interpreting the biological information. While emerging techniques have made it possible to measure inter-cellular variability at the transcriptome level, no consensus yet exists on the most appropriate method of data analysis of such single ce...
