Comparative Models in German Elections: Using the German Far-Right Party as a Proxy for Ethnic Conflict

In 2017, the Alternative für Deutschland (AfD) became the first the far-right party to win seats in the Bundestag since 1933. By campaigning on ethnic division, the AfD saw an unprecedented rise in support, especially in East Germany. This paper tests two models of ethnic conflict within comparative politics, primordialism and constructivism, to see which better explains the result of the AfD’s 2017 election. By examining the rhetorical use of political advertisements, the Manifesto Project’s analysis of the AfD’s platform, and differences of support between East and West Germany, the paper finds that constructivism better shows that highly-educated elites within the AfD purposefully constructed ethnic division to gain political support. Clear implications are drawn for the future of the two ethnic models and for European far-right politics

Killer Cell Inhibitory Receptor Recognition of Human Leukocyte Antigen (HLA) Class I Blocks Formation of a pp36/PLC-γ Signaling Complex in Human Natural Killer (NK) Cells

The killer cell inhibitory receptors (KIR) of human natural killer (NK) cells recognize human leukocyte antigen class I molecules and inhibit NK cell cytotoxicity through their interaction with protein tyrosine phosphatases (PTP). Here, we report that KIR recognition of class I ligands inhibits distal signaling events and ultimately NK cell cytotoxicity by blocking the association of an adaptor protein (pp36) with phospholipase C-γ in NK cells. In addition, we demonstrate that pp36 can serve as a substrate in vitro for the KIR-associated PTP, PTP-1C (also called SHP-1), and that recognition of class I partially disrupts tyrosine phosphorylation of NK cell proteins, providing evidence for KIR-induced phosphatase activity

The IMGT/HLA database

It is 14 years since the IMGT/HLA database was first released, providing the HLA community with a searchable repository of highly curated HLA sequences. The HLA complex is located within the 6p21.3 region of human chromosome 6 and contains more than 220 genes of diverse function. Of these, 21 genes encode proteins of the immune system that are highly polymorphic. The naming of these HLA genes and alleles and their quality control is the responsibility of the World Health Organization Nomenclature Committee for Factors of the HLA System. Through the work of the HLA Informatics Group and in collaboration with the European Bioinformatics Institute, we are able to provide public access to these data through the website http://www.ebi.ac.uk/imgt/hla/. Regular updates to the website ensure that new and confirmatory sequences are dispersed to the HLA community and the wider research and clinical communities. This article describes the latest updates and additional tools added to the IMGT/HLA project
