A Specialized Tissue Collection Device for the Preservation and Transportation of Needle Biopsies

The ability to hold and transport tissue, especially needle biopsies in a pre-defined and controlled environment is critical for the preservation of biopsy samples in downstream analytic applications. Currently, tissue specimens are placed in open containers with variable, poorly controlled solutions applied to them, often in less than sterile conditions.  Evaluation of the tissue by examination through a stereoscope or similar approaches to determine adequacy is limited and requires manipulation of the tissue that can further damage the tissue.

Single domain CD4, HIV-1 Antibodies, and Fusion Proteins for treatment of HIV

Soluble forms of human CD4 (sCD4) inhibit HIV-1 entry into immune cells.  Different forms of sCD4 and their fusion proteins have been extensively studied in animal models and clinical trials as promising HIV-1 inhibitors. However, they have not been successful in clinical trials due to their transient efficacy.  sCD4 is also known to interact with class II major histocompatibility complex (MHCII) and, at low concentrations, could enhance HIV-1 infectivity. 

T Cell Receptors Targeting p53 Mutations for Cancer Immunotherapy and Adoptive Cell Therapy

The tumor protein p53 is a cell cycle regulator. It responds to DNA damage by triggering the DNA repair pathway and allowing cell division to occur or inducing cell growth arrest, cellular senescence, and/or apoptosis. p53 therefore acts as a tumor suppressor by preventing uncontrolled cell division. However, mutations in p53 that impair its cell cycle regulatory functions can induce uncontrolled cell division leading to cancer.

Eye Tracking Application in Computer Aided Diagnosis and Image Processing in Radiology

Medical imaging is an important resource for early diagnostic, detection, and effective treatment of cancers. However, the screening and review processes for radiologists have been shown to overlook a certain percentage of potentially cancerous image features. Such review errors may result in misdiagnosis and failure to identify tumors. These errors result from human fallibility, fatigue, and from the complexity of visual search required.

Methods for Producing Stem Cell-Like Memory T Cells for Use in T Cell-Based Immunotherapies

T cells currently employed for T cell-based immunotherapies are often senescent, terminally differentiated cells with poor proliferative and survival capacity. Recently, however, scientists at the National Cancer Institute (NCI) identified and characterized a new human memory T cell population with stem cell-like properties. Since these T cells have limited quantities in vivo, the scientists have developed methods by which high numbers of these cells can be generated ex vivo for use in T cell-based immunotherapies.

A Dendritic Cell Vaccine to Immunize Cancer Patients Against Mutated Neoantigens Expressed by the Autologous Cancer

Vaccines against non-viral cancers target mainly differentiation antigens, cancer testis antigens, and overexpressed antigens.  One common feature to these antigens is their presence in central immunological tolerance. Using these vaccines, T cells underwent depletion of high avidity clones directed against such antigens. This depletion can cause the loss of T cells bearing high affinity T cell receptors (TCRs) for their cognate antigens which have superior cytotoxic capacity, longer persistence in the tumor microenvironment, and decreased susceptibility to immune suppression.

A Triple Combination HIV Microbicide

The HIV-positive population continues to rise despite a worldwide decline in the rates of infection caused by human immunodeficiency virus (HIV).  The HIV virus continues to spread due to a lack of effective vaccines and pre-exposure prophylaxis methods, even though the availability and effectiveness of antiretroviral therapy has helped reduce acquired immunodeficiency syndrome (AIDS)-related deaths. 

Nucleic Acid Nanoparticles (NANP) and Methods of Using Same for Controlled Immunomodulation

The technology is directed to compositions and methods of designing nucleic acid nanoparticles (NANPs) composed entirely of DNA, RNA, or DNA and RNA to achieve desirable immunostimulation and decrease undesirable effects on the immune system by changing the composition of the NANP. Benefits of the invention include the desirable activation of the immune system by these particles to increase the efficacy of vaccines and immunotherapies.

New Chimeric Antigen Receptor (CAR) Format for Developing Improved Adoptive Cell Therapies

Adoptive cell therapy (ACT) is an attractive new therapeutic approach for treating various cancers. ACT has recently demonstrated a high degree of efficacy when treating patients with hematological malignancies. However, to date, no effective Chimeric Antigen Receptors (CAR) T cell therapy exists for solid tumors.
