Vista sequence

Below is the results page. It lists every organism you submitted, and provides you with three viewing options using each organism as base. These three options are: Text Browser, which provides all the detailed information -- sequences, alignments, conserved sequence statistics, etc; VISTA Browser, which is an interactive visualization tool which can be used to dynamically browse the resulting alignments and adjust VISTA curve and conserved sequence parameters; and a PDF file, which is a static VISTA plot of the alignment.

At the bottom of the table there is a link that allows you to adjust conservation and visualization parameters. By clicking on it, the user can change certain parameters that are used to calculate conserved regions and to display VISTA graphs for each pair of submitted sequences. At the top of the page is a banner that displays the aligned organisms. The sequence listed in the darker header area is acting as base to choose a different base, go back to the results page and click on the Text Browser link next to the desired base sequence name.

This banner also lists the program used to align your sequences. Underneath is the navigation area, which shows the coordinates of the currently displayed region, offers a link to the Vista Browser see below , and a link to a list of all conserved regions found. In addition, if Shuffle-Lagan was used as the alignment program, there will be a link to download dot-plots of the produced alignments.

Following that is the main table, which lists each alignment that was generated for the base organism. Each row is a separate alignment. Each column, except the last one, refers to the sequences that were submitted for analysis. The last column contains information pertaining to the whole alignment.

The first cell of each row also contains a preview of the VISTA plot of this particular alignment, which allows one to quickly evaluate the quality of this alignment and to see alignment overlaps. By looking at a row in this table, you can see which section of each organism aligned to which.

The "Sequence" links will return a fasta-formatted piece of the organism sequence that participates in the alignment. The last column provides links to alignments in human readable and MFA multi-fasta alignment formats, a list of conserved regions from this alignment alone, and links to pdf plots of this alignment alone.

The browser's clean display makes it easy to identify regions of high conservation across multiple species. The PDF file is the visual representation of the alignment and conserved regions found.

This graph shows the percent of conservation or percent difference, if you used the cVISTA option between the two organisms at any given coordinate. The top and bottom percentage bounds are shown to the right of every row.

The coloring of the different conserved regions corresponds to the annotation of the region. Gaps in the base sequence are signified by red sections of line underneath the plot. The color legend is summarized in the upper left-hand corner of the display. Arrows signifying genes are drawn above the graphs, pointing in the direction of the gene. Alignments are aligned to other alignments using the sum-of-pairs metric.

Abstract VISTA is a potent negative regulator of T cell function that is expressed on hematopoietic cells and leukocytes. Keywords: Antibody immunotherapy, growth factor receptors and other surface molecules as targets for therapy, immunomodulation, VISTA, Checkpoint regulators. Introduction Immune responses must be tightly controlled to allow effective clearance of invading pathogens or cancerous cells, and yet maintain tolerance to self.

Cell Preparation Human apheresis samples were obtained from unidentified healthy human donors. Flow Cytometry For staining following culture, cells were harvested and transferred into V-bottomed well plates.

Immunohistochemistry We performed a fluorescence-based multiplex IHC assay as previously described[ 19 ] with slight modifications in Leica Bond automated staining station. Open in a separate window. Discussion The studies presented are the first to describe the structure, function and expression of human VISTA, a novel, hematopoietically-expressed negative checkpoint regulator. We propose VISTA as a promising new target for cancer immunotherapy, either as a single target or in combination with other immunotherapeutic strategies VISTA has an interesting expression pattern, with greatest mRNA detected in either hematopoietic tissues i.
