This technology includes MRS4322, which is an A3 agonist that is currently being evaluated for treatment of traumatic brain injury. Although its affinity in the receptor is in the micromolar range, it enters the brain in sufficient concentration to activate a protective CNS receptor, A3 adenosine receptor. Potential applications of such A3 agonists could also include neurodegenerative conditions.

Scientists at the NIH disclosed a novel adeno-associated virus (AAV) termed "44-9." AAV44-9 based vectors have high gene transfer activity in a number of cell types, including salivary gland cells, liver cells, and different types of neurons (e.g., cells of the cortex, olfactory bulb, and brain stem, and Purkinje cells of the cerebellum). These vectors can increase the transduction efficiency and decrease the potential of being neutralized by preexisting antibodies compared to the wild type AAV.

Methods for modifying the genome of a Neural Stem Cell (NSC) are disclosed. Also, methods for differentiating NSCs into neurons and glia are described. NSCs are multipotent, self-renewing cells found in the central nervous system, capable of differentiating into neurons and glia. NSCs can be generated efficiently from pluripotent stem cells (PSCs) and have the capacity to differentiate into any neuronal or glial cell type of the central nervous system.

This technology provides a novel method of treating or preventing pruritis (itch) using natriuretic polypeptide b (Nppb) blocking agents. Itch (also known as pruritis) is a sensation that may be perceived as an unpleasant skin irritation and may drive an urge to scratch. Conditions such as, for example, psoriasis, atopic dermatitis, renal failure, liver cirrhosis and some cancers may cause persistent itch. Itch is triggered by somatosensory neurons expressing the ion channel TRPV1 (transient receptor potential cation channel subfamily V member 1).

Knockout mouse is a valuable model to study biological functions of target genes. When Cre expressing mice are bred with mice containing a loxP-flanked gene, the gene between the loxP sites will be deleted in the offsprings. Scientists at the NIH have generated mNF-H-cre transgenic mouse lines that express Cre recombinase under the control of the promoter of the neurofilament-H gene, which is expressed in the late stage of neuronal maturation. The transgenic mice express cre in neurons (but not astrocytes) with highest expression in the cortex and hippocampus.

This technology includes GABAa a5 Negative Allosteric modulators (GABAa a5 NAMs) which have been recently discovered to act as fast-acting antidepressants in a variety of mouse models of depression. These NAMs are actively metabolized in vivo. This invention involves the conceptualization and synthesis of GABAa a5 NAM molecules with a deuterium in the active metabolic position. This significantly increased the metabolic stability, while still retaining the antidepressant activity.

CDC researchers have developed an improved dynamometer device and method for measuring maximum hand grip force or grip-strength. Human test subjects were used in conducting experiments to evaluate the handle and to assess the measurement method. In contrast to the currently used "Jamar handle" grip strength dynamometer devices, the cylindrical handle proved to be able to determine the overall grip strength for a subject, as well as show the grip force distribution around the circumference of the handle.

CDC researchers have developed the Portable Exposure Assessment System (PEAS), a field-based, remotely deployed tool to monitor and provide early warning of working conditions that have a high likelihood of musculoskeletal injury. PEAS is a noninvasive, real-time, instrument-based system. Sensor technology simultaneously measures and collects data regarding the body loads and awkward postures imposed by package handling as well as driving-related, low-frequency vibrations.

This CDC-developed technology describes a novel ergonomic device that supports a portion of the worker's weight while kneeling, relieving the knee pressure and pain common to many manual labor occupations. Unfortunately, many of the devices that have been used in the past to relieve pressure on the knees are bulky, heavy, and of questionable durability.
