The availability of genomic clones representative of the T-cell receptor constant gamma (TRGC) ovine genes enabled us to demonstrate, by fluorescent in situ hybridization (FISH) on cattle and sheep metaphases, the presence of two T-cell receptor gamma (TRG1@ and TRG2@) paralogous loci separated by at least five chromosomal bands on chromosome 4. Only TRG1@(More)
gammadelta T cells commonly account for 0.5%-5% of human (gammadelta low species) circulating T cells, whereas they are very common in chickens, and they may account for >70% of peripheral cells in ruminants (gammadelta high species). We have previously reported the ovine TRG2@ locus structure, the first complete physical map of any ruminant animal TCR(More)
A series of genomic clones derived from a sheep library were used to determine the germline configuration and the exon-intron organization of TRGC2, TRGC3, and TRGC4 genes. Based on the outcomes of molecular analysis, we compared and aligned the genomic sequences with the known complete cDNA sequences of sheep and deduced the exon-intron organization of(More)
The availability of genomic clones representative of the T cell receptor gamma (TRG1@ and TRG2@) ovine loci enabled us to compare the germline genomic organization and nucleotide diversity of joining (J) segments and reconstruct their evolutionary history by phylogenetic analysis of cattle, sheep and human expressed sequences. Expression profiling (RT-PCR(More)
BACKGROUND In humans and mice ("gammadelta low species") less than 5% of the peripheral blood T lymphocytes are gamma/delta T cells, whereas in chicken and artiodactyls ("gammadelta high species") gamma/delta T cells represent about half of the T cells in peripheral blood. In cattle and sheep (Bovidae) two paralogous T cell receptor gamma loci (TRG1 and(More)
Twelve patients, aged 35 to 60, having adult periodontitis were treated with scaling and root planning performed with ultrasonic and hand scalers. Biopsies were taken, gingival crevicular fluid and clinical parameters were analyzed at different times, and the healing process was monitored. Findings showed a clear correlation between the amount of crevicular(More)
In order to evaluate the structural potentialities of the placenta, we analyzed placentas in the following conditions: normal full term gestation, hypertensive status, twin pregnancy and abortion at 8-12 weeks of gestation, comparing cell structures, surface organization and tissue reaction. We quantitatively evaluated (1) the arborization of the placental(More)
