PHA-stimulated (3 days) or freshly isolated human peripheral lymphocytes were fixed and permeabilized with FOXP3 Fix/Perm Buffer Set. Cells were then stained with IRF4 (clone IRF4.3E4) Alexa Fluor® 647 (open histogram with solid line: unstimulated cells, filled histogram: stimulated cells) or rat IgG1, κ Alexa Fluor® 647 isotype control (dashed line: unstimulated cells, dotted line: stimulated cells).

Description

The IRF family consists of at least nine members. IRF4 and IRF8 are highly homologous to each other and also redundant in function. IRF4 is critical for Th2 and Th17 development. Together with TRF8, it plays an essential role in macrophage and dendritic cell development and function. IRF4 is also reported to be essential for pre-B cell development, receptor editing, germinal center reactor and plasma cell differentiation.
