Immunogenic fusion proteins against coronavirus. A fusion protein is disclosed, which comprises a CD40-binding domain; an antigen of SARS-CoV2; a translocation domain located between the CD40-binding domain and the antigen, and a furin and/or cathepsin L cleavage site located between the CD40-binding domain and the translocation domain. In one embodiment, the translocation domain is a Shiga toxin (Stx) translocation peptide, and the antigen is located at the N-terminal of the fusion protein. In another embodiment, the translocation domain is a Pseudomonas Exotoxin A (PE) translocation peptide, and the CD40-binding domain is located at the N-terminal of the fusion protein. Also disclosed are pharmaceutical compositions, expression vectors and use of the fusion proteins of the invention for eliciting an antigen-specific cell-mediated immune response, and/or for reducing, inhibiting, treating and/or ameliorating symptoms caused by SARS-CoV2 infection in a subject in need thereof.

4-Amino-imidazoquinoline compounds and use thereof are disclosed. The compounds of the invention are Toll-like receptor 7 (TLR7) and TLR8 dual agonists, which exhibit activities in inducing IL-12 and IP-10 expression without over-inducing IL-6. The TLR 7/8 dual agonists are potentially useful medications as immune response modifiers. Use of a compound or salt thereof according to the invention in the manufacture of a medicament for treating a disease or a condition wherein activation of TLR7 and/or TLR8 provides a benefit in a subject in need thereof is disclosed. A compound or a pharmaceutical composition for use in treating a viral infection, cancer, and/or an allergic disease, or for use in activating immune responses that are effective against a viral infection, a tumor, and/or an allergic disease in a subject in need thereof is also disclosed.

A method of manufacturing a sensor comprises: providing a substrate; forming a photoresist layer on the substrate, wherein the photoresist layer comprises a hole array which comprises a plurality of holes which pass through from one side of the photoresist layer to the substrate; sputtering a metallic glass material on the photoresist layer to deposit the metallic glass material on a hole wall of each hole and a part of the substrate defined by the hole wall; removing the photoresist layer and forming a nanotube array structure of the metallic glass material, wherein the nanotube array structure comprises a plurality of nanotubes, and each nanotube has an open end opposite to the substrate; performing a surface treatment on the nanotube array structure to form a plurality of functional groups in each nanotube; and anchoring a plurality of aptamers in each nanotube by activating the plurality of functional groups.
摘要:
A testing cartridge for metering of a sample to be tested. The testing cartridge includes a casing defining a casing opening and a sliding member defining a sliding member opening. The casing opening or the sliding member opening can define a specified volume, wherein the casing opening and the sliding member opening collectively define a sample application region dimensioned to accommodate receiving an amount of sample exceeding the specified volume. The sliding member is movable transversely to the casing opening by having the sliding member and the casing traverse across each other's respective openings to remove excess sample from the received amount of sample and retain the specified volume from the received amount of sample.

摘要:
A surface egress and/or ingress housing is provided for an elongate flexible member. A front opening in a front surface of the housing can receive a connector for the elongate flexible member. A base of the housing can be at least partially received under an embedding layer for mounting the housing on the surface. An internal cavity in the housing can communicate with the front opening and with a rear opening in the base. The rear opening and the cavity can be wider than the elongate flexible member to facilitate mounting of the housing.
摘要:
Fusion proteins for immunotherapy against cancer and infectious diseases are disclosed. A fusion protein according to the invention comprises a CD40-binding domain; an antigen; and a translocation domain located between the CD40-binding domain and the antigen, in which a furin and/or cathepsin L cleavage site is present in the fusion protein between the CD40-binding domain and the translocation domain. The antigen is an antigen of a pathogen or a tumor antigen. The furin and/or cathepsin L cleavage site permits removal of the CD40-binding domain away from the fusion protein via furin and/or cathepsin L cleavage. Also disclosed are pharmaceutical compositions, expression vectors and use of the fusion proteins of the invention for eliciting an antigen-specific cell-mediated immune response, treating a tumor and/or a disease caused by a pathogen in a subject in need thereof.
