NOS2 and infection: Whereas the frequency of transcripts expressed by innate immune cells (i.e., Tnf, Il6, Inos, Il12) in the granuloma at different time points after infection was similar, several transcripts expressed by T- or B cells (Cd3e, Cd19, Ccr6, Ifng) showed an increased relative localization in the granuloma at later time points.
