HLA-G genetic variants and hepatocellular carcinoma: a meta-analysis

A. V. C. Coelho, Moura, R. R., Crovella, S., Celsi, F., Coelho, A. V. C., Moura, R. R., Crovella, S., and Celsi, F., HLA-G genetic variants and hepatocellular carcinoma: a meta-analysis, vol. 15, p. -, 2016.

Human leukocyte antigen (HLA)-G is a key tolerogenic molecule mainly expressed in the placenta and is crucial for implantation of the embryo and immunological tolerance of the fetus during pregnancy. However, under pathological conditions, such as cancer or viral infections, HLA-G can be expressed in other tissues. The gene coding for HLA-G (HLA-G, chromosome 6p21.3) presents numerous polymorphisms, some of them influencing its expression. One of the most studied, is the 14 bp ins/del (rs371194629) situated at the 3'-UTR of the gene.

Characterization and phylogenetic analysis of the swine leukocyte antigen 3 gene from Korean native pigs

H. Y. Chung, Choi, Y. C., and Park, H. N., Characterization and phylogenetic analysis of the swine leukocyte antigen 3 gene from Korean native pigs, vol. 14, pp. 5270-5279, 2015.

We investigated the phylogenetic relationships between pig breeds, compared the genetic similarity between humans and pigs, and provided basic genetic information on Korean native pigs (KNPs), using genetic variants of the swine leukocyte antigen 3 (SLA-3) gene. Primers were based on sequences from GenBank (accession Nos. AF464010 and AF464009). Polymerase chain reaction analysis amplified approximately 1727 bp of segments, which contained 1086 bp of coding regions and 641 bp of the 3'- and 5'-untranslated regions.

N-terminal functional region of the invariant chain efficiently targets the binding of a CTL epitope to MHC class I molecules during cross-presentation

C. Wu, Zhang, D. G., Chen, F. F., Liu, X. L., Liu, S. J., and Yu, W. Y., N-terminal functional region of the invariant chain efficiently targets the binding of a CTL epitope to MHC class I molecules during cross-presentation, vol. 13, pp. 2438-2450, 2014.

Cross-presentation (CP) is important for priming T cell responses to many viral, bacterial, and tumor antigens. Here, we designed two Ii mutants, based on evidence that the invariant chain (Ii, also named CD74) binds newly synthesized MHC class I molecules with the class II-associated invariant chain peptide (CLIP) region of Ii, which occupies the peptide-binding groove.
