Background and Objective: As the main virulence factor of Helicobacter pylori, HP-NAP has an important role in immunoprotection against this pathogen. This antigen is a strong candidate as a part of multi-component vaccine in the clinical trial against this bacterium. Due to NAP importance, it was used in this study as a template for optimization of heterologous genes with a low A-T content and...
Cutaneous biopsies (n = 94) obtained from 88 patients with American tegumentary leishmaniasis were studied by conventional and immunohistochemical techniques. Specimens were distributed as active lesions of cutaneous leishmaniasis (n = 53) (Group I), cicatricial lesions of cutaneous leishmaniasis (n = 35) (Group II) and suggestive scars of healed mucosal leishmaniasis patients (n = 6) (Group II...
A Th1/Th2 imbalance in tuberculosis (TB) patients caused by a decreased Th1 response and an increased Th2 response is a significant factor in the pathogenesis and development of TB. Protective immune responses to TB include bacteriostatic and bactericidal responses. Unfortunately, however, immunoprotection and immune pathology co-exist in TB patients. Immunotherapy for TB principally aims to re...
The macromolecules contributed by the freshwater gastropod Biomphalaria glabrata, intermediate host of Schistosoma mansoni, to developing offspring inside egg masses are poorly known. SDS-PAGE fractionated egg mass fluids (EMF) of M line and BB02 B. glabrata were analyzed by MALDI-TOF (MS and tandem MS). A MASCOT database was assembled with EST data from B. glabrata and other molluscs to aid in...
Stress is thought to be immunosuppressive but paradoxically exacerbates inflammatory and autoimmune diseases. We initially showed that acute stress enhances skin immunity. Such immunoenhancement could promote immunoprotection in case of wounding, infection or vaccination but could also exacerbate immunopathological diseases. Here we identify the molecular and cellular mediators of the immunoenh...
Respiratory Syncytial Virus (RSV) is a major pathogen causing low respiratory tract disease (bronchiolitis), primarily in infants. Helminthic infections may alter host immune responses to both helminths and to unrelated immune triggers. For example, we have previously shown that filarial cystatin (AvCystatin/Av17) ameliorates allergic airway inflammation. However, helminthic immunomodulators ha...
The majority of group B streptococcus (GBS) isolates express one or more of a family of surface-anchored proteins that vary by strain and that form ladder-like patterns on Western blotting due to large repeat units. These proteins, which are important as GBS serotype markers and as inducers of protective antibodies, include the alpha C (Calpha) and R4 proteins and the recently described alpha-l...
Caseous Lymphadenitis (CL) is an infectious chronic disease that affects sheep and goats, worldwide distribution, caused by Corynebacterium pseudotuberculosis which leads to formation of granulomas in superficial lymph nodes and some internal organs. A naturally attenuated strain of C. pseudotuberculosis, called T1was recently isolated, showing considerable promise as likely immunogen in initia...
Islet transplantation in diabetes is hampered by the need of life-long immunosuppression. Encapsulation provides partial immunoprotection but could possibly limit oxygen supply, a factor that may enhance hypoxia-induced beta cell death in the early posttransplantation period. Here we tested susceptibility of alginate microencapsulated human islets to experimental hypoxia (0.1-0.3% O2 for 8 h, f...
