TRB or IGH gene usage in T1D. One Tconv sample derived from spleen (nPOD 6263) was sequenced in two separate runs. From this technical replicate, we approximated a clonal abundance threshold for reproducible sampling of the repertoire pool (%; Supplemental Figure 1 ). For clones present at or above this cutoff, we examined pLN TRBV and IGHV gene usage and observed apparent trends toward unique V gene family distribution within the T and B cell subsets for T1D versus control subjects ( Figures 2 and 3 ). These data suggest that T1D subjects demonstrate multiple receptor biases ( 27 ); however, we cannot exclude the possibility that this observation may be subject to HLA influences or other components of disease state.
Phloem is an equally important plant tissue as it also is part of the 'plumbing system' of a plant. Primarily, phloem carries dissolved food substances throughout the plant. This conduction system is composed of sieve-tube member and companion cells, that are without secondary walls. The parent cells of the vascular cambium produce both xylem and phloem. This usually also includes fibers, parenchyma and ray cells. Sieve tubes are formed from sieve-tube members laid end to end. The end walls, unlike vessel members in xylem, do not have openings. The end walls, however, are full of small pores where cytoplasm extends from cell to cell. These porous connections are called sieve plates. In spite of the fact that their cytoplasm is actively involved in the conduction of food materials, sieve-tube members do not have nuclei at maturity. It is the companion cells that are nestled between sieve-tube members that function in some manner bringing about the conduction of food. Sieve-tube members that are alive contain a polymer called callose, a carbohydrate polymer, forming the callus pad/callus, the colourless substance that covers the sieve plate. Callose stays in solution as long as the cell contents are under pressure. Phloem transports food and materials in plants upwards and downwards as required.
