In mammals, T cells develop along two discrete pathways characterized by expression of either the αβ or the γδT cell receptors. Human, mouse, and dog display a low peripheral blood γδ T cell percentage, while sheep accounts for a high proportion of γδ T lymphocytes. In all these species, the genomic organization of the T cell receptor gamma (TRG) locus is(More)
The present study identifies the genomic structure and the gene content of the T cell receptor beta (TRB) locus in the Oryctolagus cuniculus whole genome assembly. The rabbit locus spans less than 600 Kb and the general genomic organization is highly conserved with respect to other mammalian species. A pool of 74 TRB variable (TRBV) genes distributed in 24(More)
In mammals, T cells develop along two discrete pathways characterized by expression of either the αβ or the γδ T cell receptors. Human and mouse display a low peripheral blood γδ T cell percentage ("γδ low species") while sheep, bovine and pig accounts for a high proportion of γδ T lymphocytes ("γδ high species"). While the T cell receptor alpha (TRA) and(More)
BACKGROUND In most species of mammals, the TRB locus has the common feature of a library of TRBV genes positioned at the 5'- end of two in tandem aligned D-J-C gene clusters, each composed of a single TRBD gene, 6-7 TRBJ genes and one TRBC gene. An enhancer located at the 3'end of the last TRBC and a well-defined promoter situated at the 5'end of the TRBD(More)
The bottlenose dolphin (Tursiops truncatus) is a mammal that belongs to the Cetartiodactyla and have lived in marine ecosystems for nearly 60 millions years. Despite its popularity, our knowledge about its adaptive immunity and evolution is very limited. Furthermore, nothing is known about the genomics and evolution of dolphin antigen receptor immunity.(More)
Ventricular arrhythmias are one of the most common causes of death in developed countries. The use of implantable cardiac defibrillators is the most effective treatment to prevent sudden cardiac death. To date, the ejection fraction is the only approved clinical variable used to determine suitability for defibrillator placement in subjects with heart(More)
RNA metabolism controls multiple biological processes, and a specific class of small RNAs, called piRNAs, act as genome guardians by silencing the expression of transposons and repetitive sequences in the gonads. Defects in the piRNA pathway affect genome integrity and fertility. The possible implications in physiopathological mechanisms of human diseases(More)
