Several Fibroblast Growth Factor Receptor 4 (FGFR4) specific antibodies with binding affinity at the nanomolar range have been successfully developed at the Genetics Branch. These antibodies have been made into different formats of therapeutic including Antibody Drug Conjugate (ADC), Bispecific T cell engager (BiTE) ae well as Chimeric Antigen Receptor (CAR)-T cells.

Proof of principle experiments have shown that when treated with FGFR4 positive tumor cells:  

Primary liver tumors and secondary hepatic malignancies are among the leading causes of cancer-related deaths. Liver metastases account for 95% of all hepatic cancers, and the liver is the most common site for organ metastasis in the body. The gut microbiome serves an important role in antitumor immunity regulating the efficacy of chemo- and immunotherapies. The liver is exposed to gut bacteria through blood from the intestine, with 70% of the whole liver’s blood supply coming from intestinal blood. Changes in the commensal microbiome may affect immune cell function in the liver.

Researchers at the National Cancer Institute (NCI) have developed a method of stimulating an immune response in humans at risk for infection by, or already infected with, an Human Immunodeficiency Virus (HIV)-1 retrovirus. This method utilizes deoxyribonucleic acid (DNA) vaccines to stimulate CD8+ T cell immune responses. The DNA vaccine encodes antigens known to be effective against retroviruses, such as HIV-1gag, gp120, nefCTL, and proCTL. The same antigens are also expressed by the pox virus vaccine, which elicits an increased immune response when combined with the DNA vaccine.

The National Cancer Institute is seeking parties interested in collaborative research to co-develop, evaluate, or commercialize a new mouse model for monoclonal antibodies and immunoconjugates that target malignant mesotheliomas.  Applications of the technology include models for screening compounds as potential therapeutics for mesothelioma and for studying the pathology of mesothelioma.

Researchers at the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) developed an MRI-method that is based on the acquisition of multiple pulsed field gradient (m-PFG) rather than single-pulsed field gradient (s-PFG) MRI sequences. In particular, double PFG (dPFG) MRI sequences offer higher sensitivity and greater robustness, as they are more sensitive to the effects of “restriction;” i.e., to water trapped within the axon’s intracellular space, and thus to the diameter of the axons.

Cancer is the second leading cause of death worldwide. The primary cause of mortality from cancer is metastasis. While the underlying mechanisms of cancer metastasis are still being unraveled, the gp78 protein involved in ER-associated degradation (ERAD) appears to play a role in metastasis in sarcoma. Targeting gp78 may be a therapeutic option in cancer treatment.

Interleukin (IL)-34 is a homodimer that is produced mainly by keratinocytes, neuronal cells and regulatory T cells (Tregs). It is believed to play important roles in chronic inflammation and the homeostasis of microglia. Currently, there is no effective treatment for many types of retinal degeneration. An improved treatment of autoimmune uveitis is also needed, as current uveitis treatment primarily uses steroidal anti-inflammation medication, which may produce significant unwanted side effects in long-term use.

The development of RNA-based nanostructures and their use in a variety of applications, including RNA interference (RNAi) and drug delivery, represents an emerging field of science, technology, and biomedicine.  RNA is a dynamic material because of its natural functionalities, its ability to fold into complex small structures, and its capacity to self-assemble. 

Interleukin-15 (IL-15) and IL-21 have been reported to support the function of anti-tumor T cells.  However, their use in the clinic has been constrained, in part, by dose-limiting toxicity and the need for repeated administration.  To overcome these limitations, researchers in the National Cancer Institute (NCI) Experimental Transplantation and Immunology Branch (ETIB) have developed synthetic IL-15 and IL-21 molecules for autocrine expression by the engineered therapeutic T cel

Tumors can develop unique genetic mutations which are specific to an individual patient. Some of these mutations are immunogenic; giving rise to autologous T cells which are tumor-reactive. Once isolated and sequenced, these neoantigen-specific TCRs can form the basis of effective adoptive cell therapy cancer treatment regimens; however, current methods of isolation are inefficient. Moreover, the process is technically challenging due to TCR sequence diversity and the need to correctly pair the a and b chain of each receptor.
