Abstract:

Naltrexone is an opioid antagonist usually used in the treatment of patients addicted to drugs or alcohol. However, since the 1980s naltrexone has been used at lower doses to treat patients with cancer and autoimmune diseases such as multiple sclerosis and Crohn’s disease. The mechanism of action of naltrexone in treating these diseases is unknown, however, evidence suggests that the drug has immune modulating effects. Toll like receptors (TLR) are type I membrane receptors that are crucial in the innate immune response. TLR recognise exogenous and endogenous ligands to induce the production o

Abstract:

Patients with inflammatory or infectious conditions such as periodontitis, peri-implantitis, osteomyelitis, rheumatoid arthritis, septic arthritis and loosened joint prosthesis display varying severity of destruction in the adjacent bone tissue. Bone loss in inflammatory diseases is considered a consequence of cytokine induced RANKL and subsequent enhanced osteoclast formation. Hence, osteotropic cytokines and their receptors have been suggested to be important for the pathogenesis of inflammation-induced osteolysis. It is, here, suggested that bacterial components, so called “pathogen associa

Abstract:

Chemokines triggered by Toll-like receptors (TLRs) are small chemoattractant proteins, which mainly regulate leukocyte trafficking in inflammatory reactions via interaction with G protein-coupled receptors. Forty-two chemokines and 19 cognate receptors have been found in the human genome. Prior to this study, only 11 chicken chemokines and 7 receptors had been reported. The objectives of this study were to identify systematically chicken chemokines and their cognate receptor genes in the chicken genome and to annotate these genes and ligand-receptor binding by a comparative genomics approach.

Abstract:

Background: In the last two decades the discovery of the Toll-Like Receptor (TLR) family in humans revealed the importance of innate immunity in providing host defence against invading pathogens. Moreover, TLRs have a vital role in mediating the interactions between the reproductive and immune systems. Similar to TLRs, (NOD)-like receptors (NLRs); retinoic acid-inducible gene-1, RIG-1-like receptors (RLRs) are also important pattern recognition receptors in the female reproductive system. Successful implantation requires effective reciprocal interactions between receptive endometrium and compe

Abstract:

Hepatitis C Virus (HCV) is the primary cause of liver transplantation due to its chronic nature in up to eighty percent of infected cases. Around 3 percent of the world’s population is infected with HCV. Treatment for HCV is a combined Ribavirin and interferon-α (IFN-α) therapy effective in only fifty to eighty percent of patients depending on HCV genotype. The growing health concern with this disease is the lack of a cure despite liver transplantation. HCV targets hepatocytes, liver cells, but is not cytolytic. HCV has been shown to induce end stage liver disease through sustained inflammatio

Recently, it has been demonstrated that invasive but nonpathogenic Salmonella typhimurium i.t. injected into melanoma B16-bearing mice led to complete regression of the tumor, although Salmonella was unable to directly kill B16 tumor cells in vitro. Since we found high levels of IFN-γ in infected tumor masses in vivo, we wondered whether this cytokine might be involved in tumor cell death. In this work, we have demonstrated that IFN-γ shows a cytotoxic effect only when administered in combination with Salmonella. In addition, this combined treatment is able to enhance TLR transcription, mainly

Abstract:

Antigen recognition by B cells results in their activation followed by specific antibody production. These events are initiated by antigen binding to their surface B cell receptors (BCR) which triggers both signalling and internalization of the receptor bound antigen to the endosome. However B cells also express features of the innate immune system such as Toll like receptors (TLRs), that can be located either on the surface of the cell or intracellularly where they recognize bacterial and viral nucleic acids. Engagement of these receptors within B cells is associated with enhancement of humor

Microbiome transformation is involved in pathogenesis of alimentary tract cancer and also in the development of Barrett’s metaplasia.

However, little is known of the AMP profile and variability within the AM. In addition, the effects of processing, storage, and preoperative preparation on AMPs in the transplant ready amniotic membrane (TRAM) are not clear. This can alter the therapeutic potential of

Abstract:

La mucosa del tracte gastrointestinal (TGI) constitueix la superfície de contacte més àmplia de l’organisme amb el medi extern. A la llum del TGI, la barrera epitelial permet la separació entre els bilions de microorganismes residents i els immunòcits. En aquest context, el manteniment de la tolerància a la microbiota resident és essencial per a preservar l’homeòstasi; qualsevol esdeveniment que causi la desregulació d’aquestes interaccions pot desencadenar respostes pro-inflamatòries com les observades a la malaltia inflamatòria intestinal (MII). Els receptors Toll-like (TLR) regulen el diàle

Abstract:

Stimulation of Toll-like receptors (TLRs) in cells of the innate immune system activates the expression of a proinflammatory and antimicrobial gene program controlled by a network of transcriptional regulators. We show that NFAT5, which belongs to the Rel family of transcription factors and was previously characterized as an osmostress responsive factor, is required for the expression of a group of TLR-responsive genes in macrophages, such as Nos2, Il6 and Tnf. NFAT5 recruitment to its target genes is dependent on IKKβ activity, de novo protein synthesis and is sensitive to histone deacetylase

Abstract:

Toll-like receptors (TLRs) are a group of trans-membrane proteins playing important roles as pattern-recognition receptors (PRRs) of innate immunity that are mainly expressed on professional antigen presenting cells (APCs). Stimulation of APC with TLR ligands, a variety of Jnolecular components derived from microorganisms, triggers innate immunity and establishes adaptive immune responses. I studied the impact of TLR specific for bacterial components on antigen processing and presentation of protective antigen (PA) of B. anthracis by bone marrow macrophages from mice.

Abstract:

L’exposition aux rayonnements ionisants de la sphère abdomino-pelvienne est associée à une haute incidence de complications. Lors des cas les plus importants, l’apparition d’ulcérations peut entrainer le décès des patients en absence de lourds traitements. Dans ces cas, des essais cliniques sont réalisés avec des Cellules Souches Mésenchymateuses (CSM). Les radiothérapies abdomino-pelvienne peuvent provoquer à court et/ou long terme des effets délétères. Des études démontrent que l’injection de motifs bactériens confère une radioprotection au niveau intestinal. Ils stimulent des récepteurs (To
