标 题:Genetically engineered coronavirus-specific effector cells for in situ synthesis of antiviral proteins
发明人：BHATNAGAR PARIJAT; SSEMADAALI MARVIN A
权利人:STANFORD RES INST INT
摘要:An example genetically engineered effector cell comprises an exogenous polynucleotide sequence that includes a receptor element, an actuator element, and an effector element. The receptor element encodes a chimeric antigen receptor (CAR) comprising an extracellular antigen binding domain operably linked to a transmembrane domain, and an intracellular signaling domain, wherein the extracellular antigen binding domain recognizes an antigen on a surface of a Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2)-infected cell. The actuator element encodes a transcription factor binding site that upregulates synthesis of an antiviral protein. The effector element encodes the antiviral protein operably linked to a signal peptide, wherein, in response to the antigen binding domain of the CAR binding to the antigen of SARS-CoV-2-infected cell, the engineered effector cell is configured to activate and, to synthesize and secrete the antiviral protein.

摘要:Some embodiments relate to genetically engineered bacterial strains for modulation of levels of the bacterial metabolite 4-ethylphenol (4EP) and its sulfated form, 4-ethylphenyl sulfate (4EPS). In some embodiments, the bacteria reduce or inhibit production of 4EP or 4EPS in the gut of a subject. The bacteria can ameliorate, delay the onset, or reduce the likelihood of one or more symptoms associated with anxiety and/or autism spectrum disorder (ASD) in the subject.

摘要:Many Gram-negative pathogens assemble adhesive structures on their surfaces that allow them to colonize host tissues and cause disease. Novel compositions which inhibit or prevent the formation of a pilus chaperone-subunit complex are disclosed. Interfering with the function of the pili chaperone negatively affects the chaperone/usher pathway which is one molecular mechanism by which Gram-negative bacteria assemble adhesive pili structures and thus prevent or inhibit pilus assembly. Also provided are methods for the treatment or prevention of diseases caused by tissue-adhering pilus-forming bacteria by inhibiting the function of pilus chaperones. Also provided are pharmaceutical preparations capable of inhibiting or preventing the formation of a pilus chaperone-subunit complex. Also provided are methods of synthesizing the N-substituted amino acid compounds and compounds useful for the synthesis thereof. In particular, novel fluorinated linker compounds and methods of synthesis are provided. Methods for using the fluorinated linker compounds in methods of solid-phase synthesis of the N-substituted amino acid compounds are also disclosed.
