IEDB-3D 2.0: Structural data analysis within the Immune Epitope Database.

The Immune Epitope Database (IEDB) catalogs T cell, B cell, and major histocompatibility complex ligand information in the context of infectious disease, allergy, autoimmunity, and transplantation. An important component of this information is three-dimensional structural data on T cell receptors, antibodies, and pairwise residue interactions between immune receptors and antigens, which we refer to as IEDB-3D. Such data is highly valuable for mechanically understanding receptor:ligand interactions. Here, we present IEDB-3D 2.0, which comprises a complete overhaul of how we obtain and present 3D structural data. A new 3D viewer experience that utilizes iCn3D has been implemented to replace outdated java-based technology. In addition, we have designed a new epitope mapping system that matches each epitope available in the IEDB with its antigen structural data. Finally, immunogenicity data retrieved from the IEDB's ImmunomeBrowser can now be used to highlight immunogenic regions of an antigen directly in iCn3D. Overall, the IEDB-3D 2.0 provides an updated tool platform to visualize epitope data cataloged in the IEDB.

Using Photovoice to Explore Quality of Life Factors of Adults With Crouzon Syndrome.

In the United States, one in 60,000 adults live with Crouzon Syndrome (CS) and facial malformations. Phenomenological studies about their lived experiences and quality of life are lacking. The purpose of this participatory action research study was to gain a richer understanding of the perceived biopsychosocial and socioecological factors that impact quality of life for adults living with CS using Photovoice. Another aim was to develop a conceptual framework of quality of life for those experiencing CS to enhance tailored health education and services. A purposeful sample of nine adults with CS were recruited from U.S. national surgery centers and support groups. Participants used photography to represent their experiences and participated in individual interviews and focus groups. Data were analyzed with the participants using thematic analysis, and 44 themes emerged which informed the development of a quality of life conceptual framework and action plan described in this article.
