Tuberculosis (TB) is an infectious disease that typically affects the lungs. Current therapies include a panel of antibiotics given over a range of 6-9 months. As a result of the expense of treatment, the extended timeframe needed for effective treatment, and the scarcity of medicines in some developing countries, patient compliance with TB treatment is very low and results in multi-drug resistant TB (MDR-TB). There remains a need for a faster, more effective treatment for TB.

Researchers at the National Cancer Institute’s Biopharmaceutical Development Program recently developed massively parallel sequencing methods for virus-derived therapeutics such as viral vaccines and oncolytic immunotherapies.

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin’s lymphoma and consists of three subtypes: activated B-cell (ABC), germinal center B-cell (GBC), and primary mediastinal B-cell (PMB). Despite advances in the front-line therapy for DLBCL, approximately one-third of patients will relapse. Substantially worse outcomes have been reported for patients diagnosed with ABC DLBCL and treated with standard chemoimmunotherapy, suggesting the need for novel strategies that improve treatment outcomes.

 A number of factors can play a detrimental role in the process of wound healing such as poor nutritional status, smoking, various drugs, cancer, and diabetes.  Wound healing impairment is a challenging clinical problem with no efficacious treatments currently available.  Nitric oxide (NO) has been shown to play a role in the process of wound healing by promoting both the proliferative and remodeling phases of healing. 

The National Cancer Institute, Cancer and Inflammation Program seeks parties interested in collaborative research to further co-develop inhibitors of STAT proteins for the treatment of cancer.

IFN-gamma and IL-10 are cytokine signaling molecules that play fundamental roles in inflammation, cancer growth and autoimmune diseases.  Unfortunately, there are no specific inhibitors of IFN-gamma or IL-10 on the market to date.

Natural killer T cells (NKT) are a unique lymphocyte population that has T-cell and NK cell functional properties in order to rapidly elicit an immune response.  alpha-galactosylceramide (alpha-GalCer) is a potent NKT stimulator and induces of IFN-gamma release to promote immunity against tumors and infectious agents.  Humans have natural antibodies against alpha-galactose, which may be one of the reasons why the human clinical trials of alpha-GalCer or KRN7000 were not very successful.

Current influenza vaccines mainly induce antibodies against the surface glycoprotein hemagglutinin (HA) that block viral attachment to its host receptors and viral membrane fusion to the host cell. The immunodominant head region of HA undergoes antigenic drift and antibodies directed to the head confer little cross-protections between strains or subtypes.

Molecular imaging is a disease-specific targeting modality that promises much more accurate diagnoses of serious diseases such as cancer and infections. Agents are being continually developed with a view to clinical translation, with several such therapies requiring measurement of very small doses. Currently, there is no way of accurately measuring small amounts of radioactivity used in many pre-clinical tracer studies, as on-the-market commercial dose calibrators measure at too high a dose range, typically at 10-1000 µCi and higher.
