Human gammadelta T cells are considered to play a vital role in protective immunity through cytokine secretion and cytotoxic activity. We report that cells expressing the Vgamma2Vdelta2+-T cell receptor (Vdelta2+ T cells) also display principal characteristics of professional antigen-presenting cells such as dendritic cells. Thus, when activated, these(More)
For acutely lethal influenza infections, the relative pathogenic contributions of direct viral damage to lung epithelium versus dysregulated immunity remain unresolved. Here, we take a top-down systems approach to this question. Multigene transcriptional signatures from infected lungs suggested that elevated activation of inflammatory signaling networks(More)
Recent evidence indicates that astrocytes have a wide range of functions, usually attributed to cells of the immune system, which are critical for maintaining a balanced homeostatic environment in the central nervous system (CNS). Moreover, these cells are known to participate in inflammatory events within the CNS by secreting cytokines such as transforming(More)
In this study we have examined the migration responses of human peripheral blood or tonsillar B lymphocytes to a selection of 27 chemokines. Freshly isolated (CD19(+)) B lymphocytes show greatly impaired in vitro chemotaxis which is overcome by overnight culture. The best responses of cultured B lymphocytes were observed with BCA-1, SLC, ELC and SDF-1,(More)
Functionally naive CD8 T cells in peripheral blood from adult humans can be fully described by their CD45RA(bright)CCR7(+)CD62L(+) cell surface phenotype. Cord blood lymphocytes, from healthy newborns, are homogenously functionally naive. Accordingly, the majority of cord blood CD8 T cells express the same pattern of cell surface molecules. Unexpectedly,(More)
