In this study, we searched the amphibian species Xenopus laevis and Silurana (Xenopus) tropicalis for the presence of genes homologous to mammalian KIRs and avian CHIRs (KRIR family). By experimental and computational procedures, we identified four related ILR (Ig-like Receptors) genes in S. tropicalis and three in X laevis. ILRs encode type I transmembrane receptors with 3-4 Ig-like extracellular domains. All predicted ILR proteins appear to be activating receptors. ILRs have a broad expression pattern, the gene transcripts were found in both lymphoid and non-lymphoid tissues. Phylogenetic analysis shows that the amphibian KRIR family receptors evolved independently from their mammalian and avian, counterparts. The only conserved structural element of tetrapod KRIRs is the NxxR motif-containing transmembrane domain that facilitates association with FcR gamma subunit. Our findings suggest that if KRlRs of various vertebrates have any common function at all, such a function is activating rather than inhibitory. (C) 2009 Elsevier Ltd. All rights reserved.

Evolution and Potential Subfunctionalization of Duplicated fms-Related Class III Receptor Tyrosine Kinase flt3s and Their Ligands in the Allotetraploid Xenopus laevis

Matthieu Paiola, Siyuan Ma, Jacques Robert

Summary: The fms-related tyrosine kinase 3 (Flt3) and its ligand (Flt3lg) play important roles in hematopoiesis and dendritic cell homeostasis. They show differences among species and duplicated genes in Xenopus laevis. The homoeologs of Flt3 and Flt3lg exhibit conformational divergence and different expression patterns in tadpoles and adult frogs. Flt3lg and Flt3 are involved in XL cell homeostasis and XL cells have hematopoietic origin. In addition, macrophage/monocyte marker Csf1r.S is expressed on XL cells, indicating a common evolutionary origin of vertebrate DCs.

Mechanisms of type I interferon production by chicken TLR21

Rodrigo Guabiraba, Damaris Ribeiro Rodrigues, Paul T. Manna, Melanie Chollot, Vincent Saint-Martin, Sascha Trapp, Marisa Oliveira, Clare E. Bryant, Brian J. Ferguson

Summary: The innate immune response relies on the ability of host cells to detect and respond to microbial nucleic acids. Toll-like receptors (TLRs) play a crucial role in this process by distinguishing self from non-self. This study focused on TLR21, an avian TLR that recognizes bacterial DNA motifs. The findings suggest that avian TLR21 shares similar activation mechanisms to mammalian TLR9, highlighting the conservation of nucleic acid sensing mechanisms across species.

Distribution and spatiotemporal development of organised lymphoid tissues in the chicken intestinal tract

Safieh Zeinali, Kate Sutton, Lonneke Vervelde

Summary: Chickens have a unique immune structure characterized by the absence of draining lymph nodes and the presence of well-developed mucosa-associated lymphoid tissue. The structure and development of chicken lymphoid tissues in the intestine, particularly Peyer's patches, have been poorly studied. However, the use of CSF1R-eGFP reporter transgenic chickens has allowed for the visualization and investigation of the development and distribution of these tissues. This research provides insights that could benefit mucosal vaccination strategies and the development of targeted vaccine delivery systems.
