Project description:Human naïve CD4 T cells were purified from healthy volunteers' blood and were differentiated into induced Tregs in vitro by culturing for 5 days in the presence of anti-CD3 and CD28 antibodies (2 µg/ml each), IL-2 (100 units/ml) and TGF-β1 (5 ng/ml) for 5 days, then in presence of anti-CD3 and CD28 antibodies for 2 days. Human iTregs were harvested on day 7 post differentiation, then treated with either vehicle or IL-21 (100 ng/ml) in serum-free RPMI media for 18 hours.
Project description:A large gap in our understanding of infant immunity is why natural killer (NK) cell responses are deficient, which makes infants more prone to viral infection. Here we demonstrate that transforming growth factor-beta (TGF-beta) was responsible for NK cell immaturity during infancy. We found more fully mature NK cells in CD11cdnR mice, whose NK cells lack TGF-beta receptor (TGF-beta R) signaling. Ontogenic maturation of NK cells progressed faster in the absence of TGF-beta signaling, which results in the formation of a mature NK cell pool early in life. As a consequence, infant CD11cdnR mice efficiently controlled viral infections. These data thus demonstrate an unprecedented role for TGF-beta in ontogeny that can explain why NK cell responses are deficient early in life.
Project description:C57BL/6 mice were subjected to sham surgery or orthotopic Hepa1-6 hepatic tumor inoculation. Spleen tissues from mice subjected to sham surgery (control mice), mice bearing a 2-week orthotopic hepatoma, and mice bearing a 4-week othotopic hepatoma were collected. Total RNA was extracted from the spleen tissues, and we used the RT² Profiler PCR array-mouse common cytokines (SABioscience) array panels to quantitate gene expression of cytokine genes from the spleens.
