Neuronal injury from ischemic stroke is aggravated by invading peripheral immune cells. Early infiltrates of neutrophil granulocytes and T-cells influence the outcome of stroke. So far, however, neither the timing nor the cellular dynamics of neutrophil entry, its consequences for the invaded brain area, or the relative importance of T-cells has been(More)
Lymphocytes use the integrin leukocyte function-associated antigen-1 (LFA-1) to cross the vasculature into lymph nodes (LNs), but it has been uncertain whether their migration within LN is also LFA-1 dependent. We show that LFA-1 mediates prolonged LN residence as LFA-1(-/-) CD4 T cells have significantly decreased dwell times compared with LFA-1(+/+) T(More)
Regulatory T-cells (Tregs) are central for immune homeostasis and divided in thymus-derived natural Tregs and peripherally induced iTreg. However, while phenotype and function of iTregs are well known, a remarkable lack exists in knowledge about signaling mechanisms leading to their generation from naïve precursors in peripheral tissues. Using antigen(More)
