TH2 and ILC2 cells both express the transcription factor GATA-3, which promotes the production of TH2 cytokines, including the interleukins (ILs). IL-5 controls the development of eosinophils in the bone marrow, as they differentiate from myeloid precursor cells. Their lineage fate is determined by transcription factors, including GATA and C/EBP. Eosinophils produce and store many secondary … WebThe tumor is characterized by large polygonal cells with abundant eosinophilic granular cytoplasm and small, round, dark-staining nuclei.
