Novel Methods of MHC-I - LILRB Checkpoint Inhibition

The technology encompasses antibodies and methods that may overcome the shortcomings of commercial checkpoint inhibitors (CPIs). Scientists at NIAID have identified MHC-I specific antibodies that selectively inhibit interactions with inhibitory leukocyte immunoglobin-like receptors (LILRs) but not T-cell receptors. Administration of the antibodies increased proliferation and activation of both innate and adaptive immune system cells, and lead to anti-tumor and anti-viral activity in an array of relevant mouse models of disease.

Neuronal Decoding Algorithm for Prosthetic Limbs

The invention is a new algorithm for decoding neuronal responses based on the discovery that neuronal spike trains can be described using order statistics. The device has applications in the direct control of prosthetic limbs by neuronal signals originating from electrodes placed in the brain. The method allows for decoding neuronal responses by monitoring sequences of potentials from neurons while specific motor tasks are carried out.

Development of Reagents to Examine the Expression and Function of CYP2J Subfamily P450s

Cytochrome P450s catalyze the metabolism of a wide range of exogenous compounds, including drugs, industrial chemicals, environmental pollutants, and carcinogens. The 2C family of cytochrome P450 metabolizes an extensive number of drugs which include tolbutamide, S-Warfarin, mephenytoin, diazepam and taxol. The inventors cloned the cDNAs for several different CYP2J subfamily members including human CYP2J2, rat CYP2J3, mouse CYP2J5, mouse CYP2J6, and mouse CYP2J9. The recombinant proteins were expressed in insect cells.

Endotracheal Tube Using Unique Leak Hole to Lower Dead Space

Through injury or diseases, human or animal lungs may become too weak to sustain a sufficient flow of oxygen to the body and to remove adequate amounts of expired carbon dioxide. The present invention is a tracheal tube ventilation apparatus which efficiently rids patients of expired gases and promotes healthier breathing. This is accomplished by creating one or more leak holes in the wall of the endotracheal tube above the larynx, such as in the back of the mouth (i.e., oropharynx), so that expired gases can leak out of the endotracheal tube.

Tryptophan as a Functional Replacement for ADP-ribose-arginine in Recombinant Proteins

Bacterial toxins such as cholera toxin and diphtheria toxin catalyze the ADP-ribosylation of important cellular target proteins in their human hosts, thereby, as in the case of cholera toxin, irreversibly activating adenylyl cyclase. In this reaction, the toxin transfers the ADP-ribose moiety of Nicotinamide Adenine Dinucleotide (NAD) to an acceptor amino acid in a protein or peptide. ADP-ribosylation leads to a peptide/protein with altered biochemical or pharmacological properties. Mammalians proteins catalyze reactions similar to the bacterial toxins.

Rapid Motion Perception MRI Navigator Method

Available for licensing and commercial development is a non-breathhold flow sensitive navigator technique for reducing respiratory motion artifacts in magnetic resonance (MR) images. The method, called Rapid Motion Perception (RaMP), tracks bulk translational motion of the heart in real-time. The position of the blood volume is a direct representation of the heart position. RaMP tracks fast-moving blood volume during systole as a marker for the heart position, while suppressing stationary or slow moving spins.

Isolation of Hybridomas Producing Monoclonal Antibodies (MAbs) Inhibitory to Human CYP2J2

The National Institutes of Health announces three specific monoclonal antibodies that strongly inhibit and/or immunoblot the human cytochrome P450 2J2 (CYP2J2).

Cytochrome P450s catalyze the NADPH-dependent oxidation of arachidonic acid to various eicosanoids found in several species. The eicosanoids are biosynthesized in numerous tissues including pancreas, intestine, kidney, heart and lung where they are involved in many different biological activities.

Vaccines Comprising Sand Fly Salivary Proteins for Control of Leishmania Infection

This invention relates to the use of several peptides from the salivary glands of various sand fly species for the control of leishmania infection. Many of these peptides were shown to be effective in eliciting potent immune responses in animal models and are excellent candidates for the development of vaccines against the disease. A vaccine comprising one of the peptides was used to protect mice challenged with parasites and salivary gland homogenates.
