Background: Coeliac disease is a chronic small intestinal immune-mediated enteropathy precipitated by exposure to dietary gluten, and possible relationships between coeliac disease and dental pathogenic conditions during childhood have been poorly investigated.
Aim: The dental pulp plays a pivotal role in the immune defence against possible entry of pathogens from teeth, and the aim of this work was to investigate quantitative transcription levels of selected genes (IL-9, IL-11, IL-15, IL-18, IL-21, IL-27, MICA, IFN-γ) coding for pro-inflammatory immune innate activities in the pulp of primary teeth from healthy children and children with coeliac disease.
Design: The pulp from primary teeth of 10 healthy children and 10 children with coeliac disease was used to extract RNA and prepare cDNA for quantitative PCR transcription analysis employing commercial nucleotide probes for selected genes.
Antimicrobial peptides (AMPs) are considered one of the most ancient components of the innate immune system. They are able to exert their protection activity against a variety of microorganisms, and are widely distributed in both vertebrates and invertebrates. In this paper we focused on an AMP identified in the Antarctic teleost Chionodraco hamatus, an icefish species.

The successive expression of pro-inflammatory cytokines and chemokines limits pathogen spread, and attracts and activates immune cells to help in the elimination of the invaders. In this paper we focused on the analyses of the 3D structures of three pro-inflammatory molecules (interleukin-1β, tumor necrosis factor-α, interleukin-8) from selected Teleost fish species (Oncorhynchus mykiss, Dicentrarchus labrax, Chionodraco hamatus) generated using as template models those of experimental homologous proteins.

In recent years the cloning of genes coding for immuno-regulatory peptides, as well as the sequencing of genomes, provided fish immunologists with a growing amount of information on nucleotide sequences. Research is now also addressed in investigating the functional immunology counterpart of nucleotide sequence transcripts in various fish species. In this respect, studies on functional immunology of T cell activities are still at their beginning, and much work is needed to investigate T cell responses in teleost fish species.

A total of 1632 ESTs from this library were initially analysed for sequence quality and vector sequences and, after this control, 1264 (77% of total clones sequenced) high-quality ESTs were further processed. The total collection of D.
