The junctional adhesion molecule (JAM)-C is a widely expressed adhesion molecule regulating cell adhesion, cell polarity and inflammation. JAM-C expression and function in the central nervous system (CNS) has been poorly characterized to date. Here we show that JAM-C(-/-) mice backcrossed onto the C57BL/6 genetic background developed a severe hydrocephalus.(More)
Cumulative T-cell receptor signal strength and ensuing T-cell responses are affected by both antigen affinity and antigen dose. Here we examined the distinct contributions of these parameters to CD4 T-cell differentiation during infection. We found that high antigen affinity positively correlates with T helper (Th)1 differentiation at both high and low(More)
How regulatory T cells (T reg cell) control lymphocyte homeostasis is not fully understood. Here we identify two T reg cell populations with differing degrees of self-reactivity and distinct regulatory functions. Triple hi (GITR hi PD-1 hi CD25 hi) T reg cell are highly self-reactive and control lympho-proliferation in peripheral lymph nodes. Triple lo(More)
The manner in which regulatory T cells (Treg cells) control lymphocyte homeostasis is not fully understood. We identified two Treg cell populations with differing degrees of self-reactivity and distinct regulatory functions. We found that GITR(hi)PD-1(hi)CD25(hi) (Triple(hi)) Treg cells were highly self-reactive and controlled lympho-proliferation in(More)
