Opportunist mycobacteria express ligands that stimulate production of human V gamma 9V delta 2 T lymphocytes.

Description : Human gamma delta T cells are known to respond at high frequencies to pathogenic mycobacteria. Here we show that opportunistic strains of mycobacteria share with pathogenic mycobacteria the ability to trigger at high frequencies human V gamma 9V delta 2 T-cell-receptor-positive T lymphocytes. Stimul...

Negative-acting factor and superantigen are separable activities of the mouse mammary tumor virus long terminal repeat.

Description : The open reading frame contained within the long terminal repeat (LTR) of mouse mammary tumor virus encodes Naf, a negative regulator of transcription, as well as a superantigen activity, Sag, which causes the deletion of specific classes of T cells. In the present study, the effect of Naf expressio...

Methylation pattern of fish lymphocystis disease virus DNA.

Description : The content and distribution of 5-methylcytosine in DNA from fish lymphocystis disease virus was analyzed by high-pressure liquid chromatography, nearest-neighbor analysis, and with restriction endonucleases. We found that 22% of all C residues were methylated, including methylation of the following...

Cell type-specific activation of mitogen-activated protein kinases by CpG-DNA controls interleukin-12 release from antigen-presenting cells.

Description : Activation of antigen-presenting cells (APCs) by invariant constituents of pathogens such as lipopolysaccharide (LPS) or bacterial DNA (CpG-DNA) initiates immune responses. We have analyzed the mitogen-activated protein kinase (MAPK) pathways triggered by CpG-DNA and their significance for cytokine ...

A neuronal learning rule for sub-millisecond temporal coding

Description : An unresolved paradox exists in auditory and electrosensory neural systems {Carr93,Heiligenberg91}: they encode behaviourally relevant signals in the range of a few microseconds with neurons that are at least one order of magnitude slower. We take the barn owl's auditory system as an example and pre...
