Monoclonal antibodies (mAbs) to the polysaccharide capsule of Cryptococcus neoformans can prolong survival in mice. However, the properties of antibodies that mediate protection are not fully understood. The IgM mAbs 12A1 and 13F1 originated from the same B cell and differ only by somatic mutations in their variable regions; yet mAb 12A1 protects against serotype D infection, while mAb 13F1 doe...
Aβ (amyloid β-peptide) has a central role in AD (Alzheimer's disease) where neuronal toxicity is linked to its extracellular and intracellular accumulation as oligomeric species. Searching for molecules that attenuate Aβ aggregation could uncover novel therapies for AD, but most studies in mammalian cells have inferred aggregation indirectly by assessing levels of secreted Aβ peptide. In the pr...
S.typhimurium is a gram negative bacterium causing serious enteric or extraintestinal infections in human, cattle and birds. These kinds of infections may lead to some permanent or nonpermanent complications like endophthalmitis, Guillain-Barre syndrome and osteomyelitis . Multi-resistant strains of S.typhimurium have been reported from several countries, and these infections are a major public...
abstract background antibiotic resistance makes antimicrobial peptides (amps) agents an alternative for treatment of pathogenic diseases. they are isolated from various animals invertebrates, vertebrates and plants. the present study shows the electrophoretic pattern of protein and peptides from vicia faba seed and reports our first attempt to study the antibacterial activity of vicia faba seed...
Background: Bioactive compounds such as terpenoids, chondroitin sulfate, and polysaccharides with added value can be found in prestine marine creatures. These compounds often do have highly valuable therapeutic applications such as being antioxidant, antitumorogenic, anti-infl ammatory and anti-angiogenic. For the latter, varieties of angiogenesis factors can suppress this issu...
The formulation of a broadly protective vaccine to prevent the serogroup B Neisseria meningitidis (MenB) disease is still an unmet medical need. We have previously reported the induction of bactericidal and protective antibodies against MenB after immunization of mice with a phage-displayed peptide named 4 L-5. This peptide mimics a capsular polysaccharide (CPS) epitope in MenB. With the aim of...
In traditional medicine, extracts of polysaccharide-containing plants are widely employed for the treatment of cutaneus wounds. The brittle star, as one of marine organisms, encompasses bioactive compounds, which confer the healing potency of damaged arms. The aim of the present study is to investigate the effects of extracted polysaccharide from the Persian Gulf brittle star )Ophiocoma erinace...
