Modern subunit vaccines require the development of new adjuvant strategies. Recently, we showed that CpG-ODN formulated with a liquid crystal nanostructure formed by self-assembly of 6-O-ascorbyl palmitate (Coa-ASC16) is an attractive system for promoting an antigen-specific immune response to weak
Biologics have changed the management of inflammatory bowel disease (IBD), but there are concerns with unexpected systemic toxicity and loss of therapeutic response following administration by injection. Rectal administration of biologics offers potentially reduced therapy costs, as well as safer
Inflammation is associated with enhanced vascular permeability, production of inflammatory markers and over production of reactive oxygen species (ROS) with depletion of endogenous antioxidants. Several drug targeting approaches to inflammation taking clues from these events have been evolved.
As a major producer of the inflammatory cytokine interleukin-1 (IL-1), peripheral macrophages can augment IL-1 expression via type 1 IL-1 receptor (IL-1R1) mediated autocrine self-amplification. In the CNS, microglial cells are the major producers of inflammatory cytokines, but express negligible
There is a clinical need for new, more effective treatments for chronic and debilitating inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis. Targeting drugs selectively to the inflamed intestine may improve therapeutic outcomes and minimize systemic toxicity. We
The effects of several antioxidants on the three major functions of human neutrophils--oxidative burst, secretion and leukotriene formation--were investigated with special emphasis on the lipophilicity. The most striking differences were obtained when ascorbate and the lipophilic ester ascorbyl
The adjuvants approved in human vaccine with recombinant/purified antigens induce weak cellular immune response and so the development of new adjuvant strategies is critical. CpG-ODN has successfully been used as an adjuvant (phase I-III clinical trials) but its bioavailability needs to be improved.
Hydroquinone has been successfully used to treat hyperpigmentation disorders for many years. Recently, new formulations containing hydroquinone have become available, including Lustra and Lustra-AF (Medicis). These products also contain glycolic acid 2%, an active antioxidant system (ascorbyl
Vitamin C (ascorbic acid) is a non-enzymatic antioxidant important in protecting the lung against oxidative damage and is decreased in lung lining fluid of horses with airway inflammation. To examine possible therapeutic regimens in a species with ascorbate-synthesising capacity, we studied the
Aspasomes of methotrexate with antioxidant, ascorbyl palmitate, were developed and optimized using factorial design by varying parameters such as lipid molar ratio, drug to lipid molar ratio, and type of hydration buffer for transdermal delivery for disease modifying activity in rheumatoid arthritis
Skin becomes thin, dry, pale, and finely wrinkled with age. Retinoids are a large class of compounds that are important in modern therapy for dermatological treatment of wrinkled skin. Of the retinoids, retinol and vitamin A palmitate are thought to induce thickening of the epidermis and to be
Background: Present investigation was aimed to develop aspasomal gel of Mometasone Furoate for the treatment of Psoriasis that are biologically active and deliver drug at controlled rate and decrease dosing frequency.
