Provided herein are proteins comprising an anti-CD26 antigen-binding domain. Also provided herein are methods of treating an aging-related disease or an inflammatory disease in a subject that include administering to the subject one of these proteins or a cell expressing one of these proteins.

Some embodiments of the present disclosure relate to one or more compositions that upregulate the production of one or more sequences of mRNA. The sequences of mRNA may encode for translation of a target biomolecule, thereby causing an increase in bioavailability of the target biomolecule within a subject that is administered the one or more compositions. In some embodiments of the present disclosure, the target biomolecule is a fusion protein with an Fc fragment, such as a toll-like receptor 3-Fc (TLR3-Fc). In some embodiments of the present disclosure, the target biomolecule is toll-like receptor 9-Fc (TLR9-Fc). In some embodiments of the present disclosure, the target biomolecule is deoxyribonuclease I-Fc (DNAse I-Fc). In some embodiments of the present disclosure, the target biomolecule is neural growth factor-Fc (NGF-Fc). In some embodiments of the present disclosure, the target biomolecule is insulin-Fc.

An antibody or an antigen-binding fragment thereof that binds to human CD38. The antibody or the antigen-binding fragment thereof can effectively bind to human CD38 and is applied to preparing a drug for treating diseases having strong CD38 expression such as multiple myeloma.

The disclosure features compositions, systems, and uses thereof, comprising polynucleotide(s) encoding target molecule(s), and polynucleotide(s) encoding repressor(s) or timer(s). The repressor(s) or timer(s) delay expression of the target molecule(s).

The present disclosure is directed recombinant T cell receptors capable of binding a CCND1 epitope and nucleic acid molecules encoding the same. In some aspects, the nucleic acid molecules further comprise a second nucleotide sequence, wherein the second nucleotide sequence or the polypeptide encoded by the second nucleotide sequence inhibits the expression of an endogenous TCR. Other aspects of the disclosure are directed to vectors comprising the nucleic acid molecule and cells comprising the recombinant TCR, the nucleic acid molecule, or the vector. Still other aspects of the disclosure are directed to methods of using the same. In some aspects, the methods comprise treating a cancer in a subject in need thereof.

The present disclosure is directed recombinant T cell receptors capable of binding a tyrosinase epitope, a MAGA-A1 epitope, a MART1 epitope, a MAGE-A3 epitope, or an SSX2 epitope and nucleic acid molecules encoding the same. In some embodiments, the nucleic acid molecules further comprise a second nucleotide sequence, wherein the second nucleotide sequence or the polypeptide encoded by the second nucleotide sequence inhibits the expression of an endogenous TCR. Other aspects of the disclosure are directed to vectors comprising the nucleic acid molecule and cells comprising the recombinant TCR, the nucleic acid molecule, or the vector. Still other aspects of the disclosure are directed to methods of using the same. In some embodiments, the methods comprise treating a cancer in a subject in need thereof.
