The disclosure provides anti-CD30 antibody-drug conjugates and methods of using the same to increase CD4.sup.+ T-cell lymphocyte count or treat 1-IIV infection. The disclosure also provides articles of manufacture or kits comprising said antibody drug-conjugates that bind to CD30 for increasing CD4.sup.+ T-cell lymphocyte count or treating HIV infection.

Methods and composition for cell-based therapy as well as somatostatin receptor-based therapy are described. For example, in certain aspects methods for administering an anti-tumor therapy using a signaling defective somatostatin receptor mutant are described. Furthermore, the invention provides compositions and methods involve a somatostatin constitutively active somatostatin receptor mutant.

The present invention relates to multimers of polypeptides which are covalently bound to molecular scaffolds such that two or more peptide loops are subtended between attachment points to the scaffold. The invention also describes the multimerization of polypeptides through various chemical linkers and hinges of various lengths and rigidity using different sites of attachments within polypeptides. In particular, the invention describes multimers of peptides which are high affinity binders and activators of CD137. The invention also includes drug conjugates comprising said peptides, conjugated to one or more effector and/or functional groups, to pharmaceutical compositions comprising said peptide ligands and drug conjugates and to the use of said peptide ligands and drug conjugates in preventing, suppressing or treating a disease or disorder mediated by CD137.

Disclosed herein are interleukin (IL) conjugates (e.g., IL-2 conjugates) and use in the treatment of one or more indications. Also described herein are pharmaceutical compositions and kits comprising one or more of the interleukin conjugates (e.g., IL-2 conjugates).

The present application relates to a method of preparing urate oxidase (Uox) including a non-nature amino acid (NNAA) and Uox prepared thereby. The present application showed that the method of preparing Uox including an NNAA may be effectively used to prolong the half-life of a protein which is difficult to be linked to a carrier.

In addition, the Uox produced by the method may be effectively used for various biopharmaceuticals since its efficacy is maintained and drug persistency increases due to site-specific conjugation of a carrier, a risk of an immune response is reduced, and it is easily separated due to formation of uniform conjugate.

Provided are structural properties of double-stranded RNA molecules for inducing RNA interference, and more specifically, a novel nucleic acid molecule structure for inducing RNAi with improved stability, and a use thereof. A nucleic acid molecule for inducing RNAi provided herein is capable of significantly improving stability of a double-stranded RNA molecule in vivo while maintaining inhibition efficiency for a target gene, and therefore, as a expandable platform for targeting various genes, the RNA nucleic acid molecule is expected to replace siRNA molecules in the art, and be usefully utilized in the field of diagnosis or treatment of various diseases in research and clinical fields.

The disclosure is directed to compositions comprising a prodrug and an immunomodulator, which can self-assemble into a nanofiber hydrogel at the site of application in a human. The prodrug comprises one or more cytotoxic agents conjugated to a hydrophilic moiety by a linker. The compositions may be used to kill cancer cells, such as glioblastoma and colorectal cancer cells.
