Tethered Interleukin-15 (IL-15)/IL-21 to Enhance T Cells for Cellular Therapy

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

A Rapid Method of Isolating Neoantigen-specific T Cell Receptor Sequences

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.

A Novel Carbohydrate Antibody to GalNac1-3Gal and Its Application for Cancer Diagnostic and Prognosis

Cervical cancer is one of the most common cancers among women worldwide. Currently, physical descriptors such as tumor size and depth are the primary factors used for deciding the course of treatment. Despite significant efforts to identify prognostic biochemical markers or therapeutic targets to improve diagnosis and treatment, none have achieved routine clinical use. An example of one previously identified biomarker is the Tn antigen, a carbohydrate moiety composed of a GalNAc residue linked to serine or threonine.

Systems and Devices for Training and Imaging an Awake Test Animal

Typical MRI imaging sessions can last over 45 minutes and depend on the subject remaining still during the procedure for accurate imaging. In particular, animals being imaged, such as rodents (rats) in an awakened state, are not readily compliant with the restricted movement required when being imaged. Current techniques for imaging awake animals focus on training them with full body restraints and head fixation using a bite bar and/or ear bars.

Multi-Foci Sonications For Hyperthermia Treatments Using Magnetic Resource-Guided High-Intensity Focused Ultrasound (MR-HIFU)

Hyperthermia has been used extensively and successfully in the treatment of solid tumors. For accessible solid tumors with impressive efficacy not amenable to surgery, ablative hyperthermia (>55°C for 20 s to 15 min) has been used as a definitive treatment. By contrast, for both radiotherapy and chemotherapy, mild hyperthermia (40-45°C for up to 1 hour) has been shown useful as an adjuvant.

Methods of Producing Effective T-cell Populations Using Akt Inhibitors

Adoptive cell therapy (ACT) uses cancer reactive T-cells to effectively treat patients. However, several obstacles inhibit the successful use of ACT for cancer treatment.  Current approaches for the expansion of T-cells may produce T-cells with a terminally differentiated phenotype that is associated with diminished anti-tumor activity and poor capacity for long-term persistence. Thus, there is a need for improved methods of obtaining an isolated population of effective T-cells for ACT. 

Two- and Three-Dimensional Autoradiographic Imaging Utilizing Charge Coupled Devices

A novel two- and three-dimensional autoradiographic device offers to improve the imaging of body tissues. Numerous methods and apparati have been proposed to produce a three-dimensional map or image of a distribution of radioactively-tagged tissues or chemical substances; however, many of these devices merely detect the radiation, not image it. This new device uses a charged coupling device (CCD) in combination with a microtome to produce numerous two-dimensional images of the radioactively-tagged tissue.
