- Cellular therapies with CD4+ T regulatory cells (Tregs) hold promise of efficacious treatment for the variety of autoimmune and allergic diseases as well as posttransplant complications. Nevertheless, current manufacturing of Tregs as a cellular medicinal product varies between different laboratories, which in turn hampers precise comparisons of the results between the studies performed. While the number of clinical trials testing Tregs is already substantial, it seems to be crucial to provide some standardized characteristics of Treg products in order to minimize the problem. We have previously developed reporting guidelines called minimum information about tolerogenic antigen-presenting cells, which allows the comparison between different preparations of tolerance-inducing antigen-presenting cells. Having this experience, here we describe another minimum information about Tregs (MITREG). It is important to note that MITREG does not dictate how investigators should generate or characterize Tregs, but it does require investigators to report their Treg data in a consistent and transparent manner. We hope this will, therefore, be a useful tool facilitating standardized reporting on the manufacturing of Tregs, either for research purposes or for clinical application. This way MITREG might also be an important step toward more standardized and reproducible testing of the Tregs preparations in clinical applications.

- We report the draft genome of the black cottonwood tree, Populus trichocarpa. Integration of shotgun sequence assembly with genetic mapping enabled chromosome-scale reconstruction of the genome. More than 45,000 putative protein-coding genes were identified. Analysis of the assembled genome revealed a whole-genome duplication event; about 8000 pairs of duplicated genes from that event survived in the Populus genome. A second, older duplication event is indistinguishably coincident with the divergence of the Populus and Arabidopsis lineages. Nucleotide substitution, tandem gene duplication, and gross chromosomal rearrangement appear to proceed substantially more slowly in Populus than in Arabidopsis. Populus has more protein-coding genes than Arabidopsis, ranging on average from 1.4 to 1.6 putative Populus homologs for each Arabidopsis gene. However, the relative frequency of protein domains in the two genomes is similar. Overrepresented exceptions in Populus include genes associated with lignocellulosic wall biosynthesis, meristem development, disease resistance, and metabolite transport.

- The identification of sensitive assay formats capable of distinguishing islet autoreactive T cells directly ex vivo in blood is a major goal in type 1 diabetes research. Recently, much interest has been shown in the cytokine enzyme linked immunospot assay (CK ELISpot), an assay potentially capable of fulfilling these difficult criteria. To address the utility of this assay in detecting autoreactive T cells, a 'wet' workshop was organized using the same fresh blood sample and coded antigens. Five different laboratories participated, using three distinct CK ELISpot assay formats. Samples from two subjects were pre-tested for responses to sub-optimal concentrations of tetanus toxoid, representing a low frequency recall response, and peptides from diabetes associated autoantigens GAD65, IA-2 and HSP60. All participants measured interferon-? production and combinations of interleukins-4, -5, -10 and -13. In the workshop 4 of 5 laboratories detected low frequency recall responses in both subjects and 3 of 5 detected at least one of the autoreactive peptide responses concordant with pre-testing. Significant assay format related differences in sensitivity and signal-to-noise ratio were observed. The results demonstrate the potential for detection of low-level autoreactive T cell responses and identify assay characteristics that will be useful for studies in type 1 diabetes. ⌐ 2003 Elsevier Ltd.
