E a molecular foundation for this phenomenon. As an 130370-60-4 Purity example, superior levels of PKB activity are needed to downregulate the expression of KLF2 and its goal gene S1P1; the latter may be the chemokine receptor that mediates T-cell exit from secondary lymphoid organs into the lymphatics (43). The downregulation of S1P1 adhering to immune activation is among the mechanisms that retains activated T cells in lymph nodes and so may well arise only if there was a strong activation of PKB. A low-affinity TCR ligand that induced the weak activation of PKB as a result might support T-cell survival and proliferation but can be unable to change off S1P1 expression and,therefore, will be struggling to retain cells while in the secondary lymphoid tissue. The premature exit of activated T cells into your blood would curtail their publicity to antigen-primed antigenpresenting cells and trigger an attenuated immune reaction.ACKNOWLEDGMENTS This project was supported by a Wellcome Belief Principal Investigate Fellowship (D.A.C.) and Program Grant no. 065975/Z/01/A.
