In kidney transplantation, donor HLA antibodies are a risk factor for graft loss. Accessibility of donor eplets for HLA antibodies is predicted by the ElliPro score. The clinical usefulness of those scores in relation to transplant outcome is unknown. In a large Dutch kidney transplant cohort, Ellipro scores of pretransplant donor antibodies that can be assigned to known eplets (donor epitope specific HLA antibodies [DESAs]) were compared between early graft failure and long surviving deceased donor transplants. We did not observe a significant Ellipro score difference between the two cohorts, nor significant differences in graft survival between transplants with DESAs having high versus low total Ellipro scores. We conclude that Ellipro scores cannot be used to identify DESAs associated with early versus late kidney graft loss in deceased donor transplants.

The present study aimed to evaluate the key characteristics of rhoptry protein 4 (TgROP4), including physicochemical parameters, structural features, immunogenic epitopes, and virtual immune simulation, using several bioinformatics-based servers and tools. Based on allergenicity and antigenicity outputs, the TgROP4 protein seemed to have an immunogenic and non-allergenic nature. The quality of the three-dimensional (3D) structure improved after refinement, according to the outcomes of the Ramachandran plot and the ProSA-web servers.

Objective: Analyze phylogenetic relationships and molecular mimicry of Cit s 2 and other plant profilins.
Methods: Online bioinformatics tools including Basic Local Alignment Search Tool (BLASTP), PRALINE and MEGA were used for multiple alignments and phylogenetic analysis. A 3D-homology model of Cit s 2 was predicted.

Different tissues of various plants contain allelochemicals such as phenolics, flavonoids, etc., which exhibit antioxidants and protect the plants from harmful infections. The widespread group of plant allelochemicals in the ecosystem is phenolic compounds.

Allorecognition of donor HLA is a major risk factor for long-term kidney graft survival. Although several molecular matching algorithms have been proposed that compare physiochemical and structural features of the donors' and recipients' HLA proteins in order to predict their compatibility, the exact underlying mechanisms are still not fully understood. We hypothesized that the ElliPro approach of single ellipsoid fitting and protrusion ranking lacks sensitivity for the characteristic shape of HLA molecules and developed a prediction pipeline named Snowball that is fitting smaller ellipsoids iteratively to substructures.
