There are potent immunomodulators in saliva of the bloodfeeding arthropods which transmit many of the world's most serious diseases that may benefit the arthropod by preventing the vertebrate host from becoming sensitized to the saliva. In addition, saliva can enhance transmission of parasites/pathogens by arthropods. As a result, vaccines that target the arthropod (e.g. salivary immunomodulato...

Helminths are the largest and most complex pathogens to invade and live within the human body. Since they are not able to outpace the immune system by rapid antigen variation or faster cell division or retreat into protective niches not accessible to immune effector mechanisms, their long-term survival depends on influencing and regulating the immune responses away from the mode of action most ...

Active-targeted delivery to lymph nodes represents a major advance toward more effective treatment of immune-mediated disease. The MECA79 antibody recognizes peripheral node addressin molecules expressed by high endothelial venules of lymph nodes. By mimicking lymphocyte trafficking to the lymph nodes, we have engineered MECA79-coated microparticles containing an immunosuppressive medication, t...

Atherosclerosis results from endothelial cell dysfunction and inflammatory processes affecting both macro- and microvasculature which are involved in vascular diabetic complications. Glucagon-like peptide-1 (GLP-1) is an incretin hormone responsible for amplification of insulin secretion when nutrients are given orally as opposed to intravenously and it retains its insulinotropic activity in pa...

t w m m c a t t s h s n t p t i e i b c c nterstitial cystitis (IC) is a disorder of the urinary bladder characterized by urgency, freuency, nocturia, and chronic pelvic pain. The ain pathologic findings include dysfunction of he bladder glycosaminoglycan protective layer1 nd a high number of activated bladder mast cells2; hese processes could lead to neurogenic inflamation and immune damage of...

HELMINTH DEFENCE MOLECULES (HDMs)—ANTIMICROBIALS OR IMMUNOMODULATORS? Parasitic helminths (worms) are one of the most successful animal groups in nature. They are large multicellular organisms and therefore cannot penetrate host cells but must reside inside tissue or organs. They infect over 1 billion people globally, mostly in tropical/sub-tropical regions, taking an enormous toll on animal an...

There is growing evidence that tumor-associated immune imbalance is an important prognostic factor in several types of malignancy. Results from basic research as well as several case reports on sarcoma patients suggest that immune function may be improved by plant immunomodulators. Such treatments hold promise to partially restore the impaired balance along the regulatory access of the innate i...

Background and aims With expanding available treatment options and evolving understanding of the risks and benefits of medical therapies for inflammatory bowel disease (IBD), there is the possibility of significant variations in treatment and outcomes. Little is known about the variation in treatment between IBD specialists and other gastroenterology (GI) physicians. Evaluating possible variati...

A highly effective strategy for combating infectious diseases is to enhance host defenses using immunomodulators, either preventatively, through vaccination, or therapeutically. The effectiveness of many vaccines currently in use is due in part to adjuvants, molecules that have little immunogenicity by themselves but which help enhance and appropriately skew the immune response to an antigen. T...

Immunoglobulin G4-related disease (IgG4-RD) is a novel clinical entity characterized by elevated serum IgG4 levels and histopathologic features of storiform fibrosis, obliterative phlebitis, tissue eosinophilia, and infiltration of IgG4-positive plasma cells. Although it can involve almost any organ, IgG4-RD rarely involves the nervous system. The principal neurologic manifestations include hyp...
