A Analysis of wild-type (+/+, n = 4), knock-in (ki/ki,
n = 4), and knock-out (ko/ko, n = 3) mice for the
presence of thymic (TH) and peripheral
CD4+CD25+Fop3+ Treg cells. SP, spleen; LN,
lymph node.
B Western blot analysis of RelB expression in total thymocytes of wild-type and knock-in
mice.
C FoxP3 mRNA levels in naïve CD4+ peripheral T cells after stimulation
with anti-CD3 and anti-CD28 in the presence of TGF-β and IL-2.
D, E Analysis of CD45.1 wild-type mice that were lethally irradiated and reconstituted with a 1:1
ratio of wild-type CD45.1+ to CD45.2+ wild-type
(+/+, n = 3) or knock-in (ki/ki, n =
4) bone marrow cells, 8 weeks after transfer. Cells from lymph nodes (LN), spleen (SP), and thymus
(TH) were analyzed. The CD45.1/CD45.2 ratio was determined in total CD4+ T cells
(D) and in CD4+CD25+FoxP3+ Treg cells (E).
F CD45.2 control (+/ki) or Malt1 knock-in mice (ki/ki) were lethally irradiated and
reconstituted with wild-type CD45.1+ bone marrow cells (reciprocal chimeras) and
T-cell development analyzed 8 weeks after transfer (n = 3).
