The present invention relates to a biologically active placenta-derived liquid human substrate (hpS) comprising extracellular matrix (ECM) proteins, cytokines and growth factors and use thereof. The present invention also provides methods of producing a composition comprising biologically active placenta-derived liquid human substrate (hpS).

Methods for producing an antibody or an antigen-binding fragment thereof specifically binding to an antigen of interest, methods for inducing proliferation of PBMCs, B cell activation and differentiation, B cell maturation, and/or promoting class switch in an antibody-producing PBMC to produce IgG, compositions for the in vitro immunization and methods for identifying an antibody-enhancing factor for in vitro immunization.

The present disclosure relates generally to the manufacture of regulatory T cells (Tregs) for use in adoptive cell therapy. In particular, the present disclosure relates to simplified approaches for the expansion of Tregs ex vivo. Tregs produced in this way are suitable for use in various immunotherapy regimens.

Provided is a method for preparation of a composition comprising activated human CD8.sup.+ and natural killer (NK) lymphocytes. The method entails use of mature dendritic cells as feeder cells added at an early stage in CD4.sup.+ mediated activation of the CD8.sup.+ cells. Also provided is a method for treatment of cancer using the cells obtained from the process.

The present invention is drawn, in part, to biocompatible compositions comprising a biocompatible polymer matrix and conditioned cell medium comprising i) a cell culture medium and ii) one or more agents synthesized by and secreted from one or more cells cultured in the cell culture medium, as well as therapeutic uses thereof, particularly in modulating bone and/or gum tissue growth.

Embodiments of the disclosure include methods and compositions for treatment or reduction in risk of coagulopathy of any kind, including associated with inflammation. In specific embodiments, the coagulopathy is associated with upregulated production of tissue factor in the individual. In specific embodiments, the coagulopathy is in an individual that has SARS-CoV-2 infection or is at risk for having SARS-CoV-2 infection. In specific embodiments, the methods and compositions include fibroblasts, and/or modified fibroblasts, and/or derivatives of fibroblasts, including those fibroblasts exposed to TNF-alpha or one or more other inflammatory agents before activation of the fibroblasts.

The current disclosure relates to methods for treating ovarian cancer based on specific antigen expression of the cancer. Furthermore, the expressed antigen may be used in immunotherapeutic methods for treatment of the ovarian cancer. Aspects of the disclosure relate to immunotherapies targeting CT45 polypeptides, methods for treating ovarian cancer based on CT45 expression, and kits for detecting CT45 polypeptides and nucleotides.

The present invention relates to a method for inducing an immune response in a human or animal subject, as well as to a pharmaceutical composition for inducing an immune response, furthermore to a method for producing the pharmaceutical composition in vitro and the use of cytotoxic CD8+ T-lymphocytes activated to recognize an antigenic peptide in a pharmaceutical composition or in a method for inducing an immune response.

The present invention relates to a composition and method for treating rheumatoid arthritis, comprising interleukins (ILs), including IL-1β, stimulated human umbilical cord mesenchymal stem cells (hUCMSCs). The IL stimulated hUCMSCs of the present invention may induce the apoptosis of fibroblast-like synoviocytes rheumatoid arthritis (HFLS-RA) cells. IL stimulated hUCMSCs are useful to alleviate RA symptoms, such as inflammation, swelling and cartilage erosion, and exhibit therapeutic effects on rheumatoid arthritis.

The present invention provides methods of expanding γδ T cells from a non-haematopoietic tissue source. Further provided are compositions of expanded γδ T cells and methods of using the expanded γδ T cells (e.g., a part of an adoptive T cell therapy).
