PTPRC and infection: Again, at different time points of infection (e.g., 12 h, d5 and d6) we observed that the expression of IL-4 was primarily found in CD45+SiglecF+ eosinophils and some other myeloid cells, but not in CD45+SiglecF− ILC2 (D. Barinberg, S. Obermeyer and U. Schleicher, unpublished observation).
