The present invention relates to recombinant chimeric molecules that are capable of providing T cell receptor (TCR) interaction and costimulation for activation and differentiation of pathogen-specific T cells toward effector T helper 1 (Th1) or T helper 2 (Th2) cells. The chimera may capable of elicit antibodies against pathogen-specific B cell epitope(s). The present invention also relates method of using these chimeric molecules in whole or as a component of a vaccine.

A targeted therapeutic including a lysosomal enzyme and a lysosomal targeting moiety that is a peptide containing at least one N-linked glycosylation site. Methods of producing the targeted therapeutic may include nucleotide acids encoding the same and host cells co-expressing GNPT. Pharmaceutical compositions comprising the targeted therapeutic and methods of using the same to treat a lysosomal storage disease.

The present invention relates, inter alia, to compositions and methods, including chimeric proteins having a first domain comprising an extracellular domain of a first transmembrane protein, a first secreted protein, or a first membrane-anchored extracellular protein and a second domain comprising an extracellular domain of a second transmembrane protein, a second secreted protein, or a second membrane-anchored extracellular protein, in which either or both of the first domain and the second domain decreases self-directed immune system activity when bound to its ligand/receptor. Accordingly, the present invention find use in the treatment of autoimmune diseases.

The present invention relates to a novel IL-10 variant protein and use thereof, and more particularly, to a novel IL-10 variant protein whose immune stimulatory activity is inhibited and yield of production is increased by forming monomers when expressed.

A selective IL-6-trans-signalling inhibitor can be used to treat a variety of IL-6-mediated conditions, including inflammatory diseases and cancer. The inhibitor can safely be administered to humans at a variety of doses. Moreover, the inhibitor lessens deleterious effects associated with other IL-6 inhibitors such as lowering neutrophil counts, platelet counts and levels of C-reactive protein.

The present invention relates generally to a method of increasing lipid oxidation in a mammal and to agents useful for same. More particularly, the present invention relates to a method of increasing lipid oxidation in a mammal by administering a ligand which interacts with the IL-6 receptor and signals via interaction with a gp130/LIF receptor heterodimer. In a related aspect, the present invention provides a method of increasing insulin sensitivity in a mammal. The method of present invention is useful, inter alia, in the treatment and/or prophylaxis of conditions characterized by unwanted lipid accumulation (such as obesity, obesity induced-metabolic disorders, type II diabetes, dyslipidemia, glucose intolerance, insulin resistance, obstructive sleep apnea, cardiovascular disease or non-alcoholic fatty liver disease) or inadequate insulin sensitivity.

A selective IL-6-trans-signalling inhibitor can be used to treat a variety of IL-6-mediated conditions, including inflammatory diseases and cancer. The inhibitor can safely be administered to humans at a variety of doses. Moreover, the inhibitor lessens deleterious effects associated with other IL-6 inhibitors such as lowering neutrophil counts, platelet counts and levels of C-reactive protein.

There is described herein a method for inducing Tc22 lineage T cells from a population of CD8+ T cells, the method comprising: a) providing a population of CD8+ T cells; b) activating the population of CD8+ T cells; and c) culturing or contacting the population of CD8+ T cells with IL-6.

Provided are a genetically modified immune cell, a preparation method therefor, and an application. The immune cell overexpresses HIL-6 and/or L-GP130. HIL-6 or L-GP130 continuous overexpression/conditionally induced overexpression in the immune cell reduces the side effects of CAR-T therapy while maintaining immune and anti-tumour effects, and has potential value in the treatment of malignant tumours and AIDS.

The disclosure relates to methods of culturing and expanding CD4+ and/or CD8+ T cells in culture. In some embodiments, the methods include expanding, proliferating and storing lymphocytes in tissue culture by exposing the lymphocytes to a combination of cytokines and/or nucleic acids expressing cytokines or functional fragments or variants thereof. The disclosure further relates to methods of generating and manufacturing CD4+ and/or CD8+ T cells that are specific to one or a plurality of viral antigens.
