Toll like receptors (TLRs) are a family of transmembrane proteins which play a key role in innate immunity. When TLRs come into contact with a potential threat, they initiate a signaling cascade leading to release of cytokines and chemokines, maturation of antigen presenting cells and immune activation. Molecules which can activate TLRs may be utilized for vaccine development and act as vaccine adjuvants. Adjuvants Read More

Gene therapy requires safe and effective vectors to deliver genes to their target site of action. Non-viral gene delivery systems have attracted growing attention due to their low toxicity, low immunogenicity and ease of production compared to viral vectors. Most non-viral gene delivery systems enter cells via endocytic pathways, and their escape from endosomes is therefore crucial for successful transfection. Several re Read More

Cancer has been affecting a growing number of children, adolescents and adult males in reproductive age. Male reproductive potential is adversely affected by chemotherapeutic drugs and patients are at risk for prolonged infertility. Fertility recovery is related to the chemotherapeutic agent and dosage used, being thus difficult to predict. As a result, there is a strong need to identify a natural or synthetic compound that is able to Read More

Early detection of pancreatic cancer has been a long-standing challenge in determining prognosis and management of the deadly disease. Although the incidence of pancreatic cancer is low (2% of all malignancies), it is the fourth leading cause of deaths attributable to cancer in the U.S. A major cause for the high mortality rate, which exceeds 85%, is the difficulty in diagnosing the disease early in its development. The rel Read More

Multimodal imaging agents were first introduced a decade ago and consist of a targeting moiety that is dual-labeled with radioactive and fluorescent contrast. These compounds allow whole-body and intraoperative imaging to be performed through administration of a single agent and provide complementary diagnostic information that can be used to guide tumor resection. Since their initial evaluation, interest in dual-l Read More
