Early Appearance of TNF-α and Other Cytokines in Bronchus Associated Lymphoid Tissues (BALT) from Growing Wistar Rats. What is the Role of TNF-α?

Several different cytokines trigger the development of determined cell subsets in BALT of growing Wistar rats. Early appearance (4 days post partum) of γδT cells in BALT has been shown, as well as its role in up-regulating TNF-α production. In the present report, we studied in the BALT: (1) the profile of the cytokines, TNF-α, INF-γ and IL-10 and (2) in TCR γδ
