Biological homeostasis is a state of steady internal, physical, and chemical conditions maintained by a living organism observed at the cellular level. Biological homeostasis can vary in order to alter the cellular physical and chemical conditions.
The Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) seeks research co-development partners and/or licensees for the development of tamper-less tensor elastography imaging in assessing disease (e.g., cancer), normal and abnormal developmental processes, degeneration and trauma in the brain and other soft tissues, and other applications.
The National Cancer Institute (NCI) seeks licensees for a CRISPR/Cas9-engineered MC38 B2m knockout murine colon cancer cell line that models tumor resistance to PD-1/PD-L1 checkpoint blockade caused by loss of MHC-I antigen presentation. This research tool provides an opportunity to study checkpoint-refractory tumors and evaluate alternative or combination immunotherapy strategies for cancers that evade conventional T-cell–mediated recognition.
Cancer immunotherapy has transformed treatment for some patients, but many tumors still do not respond well to current options, including checkpoint inhibitors. Researchers at NIAID’s Laboratory of Immune System Biology (LISB) have developed new antibodies designed to help the immune system fight tumors. These lab-made antibodies, called pan-anti-HLA monoclonal antibodies, block signals that can limit immune cell activity.
In research settings, visualization of tumors or tumor cells is often done using either bioluminescence or fluorescence. However, both of these methods have shortcomings: bioluminescence is not sensitive enough to sort individual tumor cells, and fluorescence cannot be used effectively to view internal tumors and is best used with surface tumors.
