Abstract: Herein, we provide genetically engineered immune effector cells, among other cells, which express CAR and secret a bispecific “trap” protein co-targeting a checkpoint protein and TGF-? or TGF-? receptor, so as to improve the antitumor immunity of the immune effector cells. Compared with conventional CAR-T cells and CAR-T cells secreting a polypeptide checkpoint inhibitor, the provided genetically engineered immune effector cells CAR-T cells with “trap” protein secretion attenuate inhibitory T cell signaling, enhance T cell persistence and expansion, and improve effector functionalities and resistance to exhaustion. In a xenograft mouse model, CAR-T cells with “trap” protein secretion significantly enhanced antitumor immunity and efficacy. Methods of using these genetically engineered cells, as well as using polynucleotides encoding the CAR and the “trap” protein, are also provided, for example, as a therapy against solid tumors.

Abstract: Provided herein are methods for detecting an antigen or for detecting expression of a chimeric antigen receptor (CAR). The methods include obtaining a sample from a subject, contacting the sample with a fusion protein comprising a reporter fused to a single chain antibody specific to the antigen or fused to an extracellular domain of an antigen targeted by the CAR or fused to Protein L and assaying the activity of the reporter, wherein presence of reporter activity or increase in reporter activity relative to a reference value is indicative of presence of the antigen or presence of the expression of the chimeric antigen receptor in the sample.

Abstract: A universal chimeric antigen receptors (CAR)-modified immune cell is provided, including engineering natural killer (NK) cells and/or T cells which recognizes 2,4-dinitrophenyl (DNP) and can subsequently be redirected to target various epitopes of envelop protein gp160 using DNP-conjugated broad neutralizing antibodies as adaptor molecules.

This system can recognize and kill mimic HIV-infected cell lines expressing at least one of subtypes B and C gp160. Presently provided system containing universal CAR-NK cells and (bNAbs) overcome the limitations of conventional anti-HIV CARs, as the latter targets a single epitope of the HIV envelope glycoprotein gp160 and falls short of countering the enormous diversity and mutability of viruses.

Abstract: Described herein is a novel, mitochondrial encoded, open reading frame, that leads to the production of a new mitochondrial peptide. Residing within the ND-Two subunit, a specific small nucleotide polymorphism disrupts expression of this mitochondrial peptide, and is correlated with an increase in obesity and diabetes, particularly in certain ethnic populations. In vitro administration of the peptide increases insulin secretion, decreases fat accumulation and improves glucose uptake in muscle cell. Antibodies generated against the peptide can be used for detecting peptide deficiency, in addition to SNP detection, supporting diagnostic approaches. In vivo studies further revealed that administration of the peptide improves glucose tolerance, thereby providing a new therapeutic avenue for a novel diabetes therapy and decreases bodyweight, thus serving as a novel obesity therapy. Generation of synthetic analogs further enhance or abrogated activity relative to the natural peptide.

Abstract: Devices, computer-readable media, and methods for making a cache admission decision regarding a video chunk are described. For instance, a processing system including at least one processor may obtain a request for a first chunk of a first video, determine that the first chunk is not stored in a cache, and apply, in response to the determining that the first chunk is not stored in the cache, a classifier to predict whether the first chunk will be re-requested within a time horizon, where the classifier is trained in accordance with a set of features associated with a plurality of chunks of a plurality of videos. When it is predicted via the classifier that the first chunk will be re-requested within the time horizon, the processing system may store the first chunk in the cache.

Abstract: A lacrimal tear flow measurement device, and methods of manufacture and use, are described that includes a polymer microcapillary tube or similar structure having at least one end coated on the outside with soft silicone rubber and one end treated on the inside to be hydrophobic. The hydrophobic end keeps liquid from escaping or entering that end while allowing air to pass. The rest of the tube's insides may be hydrophilic or a neutral hydrophobe. As a Schirmer's test strip replacement, the entrance end of the device can be touched to the lacrimal lake of a patient's eye to collect suck up, or merely collect, tear fluid within the collection tube for weighing, volume measurement, or other analysis. Long-term collection devices for wear between doctors' visits can have a bypass channel allowing liquid to flow back onto the eye.
